            Explaining climate change science & rebutting global warming misinformation

            Scientific skepticism is healthy. Scientists should always challenge themselves to improve their understanding. Yet this isn't what happens with climate change denial. Skeptics vigorously criticise any evidence that supports man-made global warming and yet embrace any argument, op-ed, blog or study that purports to refute global warming. This website gets skeptical about global warming skepticism. Do their arguments have any scientific basis? What does the peer reviewed scientific literature say?

            Lobbying against key US climate regulation ‘cost society $60bn’, study finds

            Posted on 10 June 2019 by Guest Author

            This is a re-post from Carbon Brief by Josh Gabbatiss

            Political lobbying in the US that helped block the progress of proposed climate regulation a decade ago led to a social cost of $60bn, according to a new study.

            Environmental economists Dr Kyle Meng and Dr Ashwin Rode have produced what they believe is the first attempt to quantify the toll such anti-climate lobbying efforts take on society.

            The pair say their work reveals the power firms can have in curtailing government action on climate change, in the face of “overwhelming evidence” that its social benefits outweigh the costs, which range from reduced farming yields to lower GDP.

            Crucially, they found that the various fossil-fuel and transport panies expecting to emerge as “losers” after the bill were more effective lobbyists than those expecting gains.

            The authors say their results, published in Nature Climate Change, support the conclusion that lobbying is partly responsible for the scarcity of climate regulations being enacted around the world.

            However, they tell Carbon Brief that there is still hope for those seeking to develop effective new climate policies:

            “Our bottom line is: climate policy emerges from a political process. We’ve shown that this political process can undermine the chances of passing climate policy. But we’ve also shown that careful design of climate policy can help make it more politically robust to opposition.”

            White House Tried to Stop Climate Science Testimony, Documents Show

            The White House tried to stop a State Department senior intelligence analyst from discussing climate science in congressional testimony this week, internal emails and documents show.

            The State Department’s Bureau of Intelligence and Research declined to make changes to the proposed testimony and the analyst, Rod Schoonover, an adjunct professor at Georgetown University, was ultimately allowed to speak before the House Permanent Select mittee on Intelligence on Wednesday.

            But in a highly unusual move, the White House refused to approve Dr. Schoonover’s written testimony for entry into the permanent Congressional Record. The reasoning, according to a June 4 email seen by The New York Times, was that the science did not match the Trump administration’s views.

            State of the climate: Heat across Earth’s surface and oceans mark early 2019

            Posted on 6 June 2019 by Zeke Hausfather

            This is a re-post from Carbon Brief

            Global surface temperatures in 2019 are on track to be either the second or third warmest since records began in the mid-1800s, behind only 2016 and possibly 2017.

            On top of the long-term  warming trend, temperatures in 2019 have been buoyed by a moderate El Niño event that is likely to persist through the rest of the year.

            That’s one of the key findings from Carbon Brief’s latest “state of the climate” report, a quarterly series on global climate data that now includes temperatures, ocean heat, sea levels, greenhouse gas concentrations, climate model performance and polar ice.

            Ocean heat content (OHC) set a new record in early 2019, with more warmth in the oceans than at any time since OHC records began in 1940.

            The latest data shows that the level of the world’s oceans continued to rise in 2019, with sea levels around 8.5 centimetres (cm) higher than in the early 1990s.

            Atmospheric methane concentrations have increased at an accelerating rate, reaching record highs in recent months, though scientists are divided on the cause of this trend.

            Arctic sea ice is currently at a record low for this time of year. Antarctic sea ice set new record lows in January, and is currently at the low end of the historical range.

            Third warmest start to a year

            Global surface temperatures are recorded and reported by a number of different international groups, including NASANOAAMet Office Hadley Centre/UEABerkeley Earth and Cowtan and WayCopernicus/ECMWF also produces a surface temperature estimate based on a bination of measurements and a weather model – an approach known as “reanalysis”.

            The chart below pares the annual global surface temperatures from these different groups since 1970 – or 1979 in the case of Copernicus/ECMWF. The coloured lines show the temperature for each year, while the dots on the right-hand side show the year-to-date estimate for January through March 2019. Values are shown relative to a mon baseline period, the 1981-2010 average temperature for each series. Surface temperature records have shown around 0.86C warming since the year 1970, a warming rate of about 0.19C per decade.

            Year-to-date values are only shown for NASA, NOAA, and Copernicus as data for March is not yet available from the UK Hadley Centre, which also prevents the Berkeley Earth and Cowtan and Way records from being released. The year-to-date values in this chart will be updated when that data bees available.

            Effects of Global Warming

            Posted on 3 June 2019 by Riduna

            Why are young – and not so young – people being more vociferous in their protests about global warming?  Why has climate change bee a political and partisan issue at democratic elections?  Why do ‘greenies’ try to stop the development of new coal mines and call for speedier reduction of our greenhouse gas emissions?  The answer is that the effects of greenhouse gas emissions, particularly Carbon Dioxide (CO2), are being increasingly evident and dangerous – although relatively mild at present, pared to what they could soon bee.

            Much is being said about the cost of reducing greenhouse gas emissions in terms of lost jobs, lost ine and harm to national and global economies but we hear relatively little about the catastrophic consequences of not reducing emissions.  Prioritising short term profit and ideology ahead of emissions reduction will inevitably result in an uncontrollable, unpredictable and destructive climate resulting in socio-economic collapse.

            Analysis of air trapped in ice cores shows that over the past 800,000 years the normal concentration of CO2 in the atmosphere varies between 170 parts per million (ppm) during cold periods (so called Ice Ages) to 260-300 ppm when the planet reaches its warmest.  Concentration of COin the atmosphere now stands at over 415 ppm and is continuing to rise at an accelerating rate as we burn ever increasing amounts of fossil fuels.

            For well over a century it has been widely known that COabsorbs infra-red light reflected from the earths’ surface then re-emits it, much of it back to the surface.  The higher the concentration of COin the atmosphere, the warmer the surface temperature gets, a phenomenon known as global warming which has a number of effects including 1. ocean warming, 2. loss of land-based ice and permafrost, 3. climate change which bees less predictable and 4. sea level rise.  Below is an outline of these effects.

            12 books on how climate change is transforming businesses and the global economy

            For some businesses and entrepreneurs, climate change isn't just a threat. It's an opportunity.


            The significant transformations required to meet the challenges posed by climate change are, from another perspective, fabulous opportunities. Inventors, entrepreneurs, and business strategists recognized this fact many years ago. Their activities have since been chronicled and analyzed by reporters, researchers, and, in some cases, the entrepreneurs themselves.

            For this month’s bookshelf on climate change and business, Yale Climate Connections has assembled two different lists. This first list covers books published in the last five years. The second list covers recent free reports on the same subject from international organizations, government agencies, and D.C.-based think tanks.

            Humans and volcanoes caused nearly all of global heating in past 140 years

            Posted on 30 May 2019 by dana1981

            Emissions from fossil fuels and volcanoes can explain nearly all of the changes in Earth’s surface temperatures over the past 140 years, a new study has found.

            The research refutes the popular climate denial myth that recent global warming is merely a result of natural cycles.

            Those arguments have always suffered a key physical flaw, namely that cycles are cyclical. For example, El Niño events, which temporarily raise global surface temperatures by bringing warm water up to the shallow ocean layer, are offset by La Niña events, which have the opposite effect. While a given decade might have more El Niño or La Niña events, resulting in a short-term surface warming or cooling, over the long term their effects cancel out.

            However, climate scientists have had a difficult time explaining exactly what caused a warming event in the early 20th century, between about 1910 and 1945. The average of the climate model runs incorporated in the last IPCC report only accounted for about half of the measured global surface warming trend during that period, and a study published last year suggested the other half could be due to natural cycles.

            Contrarian scientists like Judith Curry, who is frequently invited by Republicans to testify before US Congress, have often used this discrepancy to cast doubt on the expert consensus on human-caused global warming, arguing that “until we can explain the early 20th century warming, I have little confidence IPCC and [National Climate Assessment] attribution statements regarding the cause of the recent warming.”

            The new study, published in the Journal of Climate, tackles the discrepancy in part by addressing an issue with ocean temperature data during the second world war, when measurements were more often made from warmer engine room intakes than from buckets lowered over the side of ships. This has resulted in a bias, inflating estimated surface temperatures in the early-to-mid 1940s. The new study removed this bias by focusing on temperatures along continental and island coastlines.

            Four scientists make creativity a key to municating their research

            Posted on 28 May 2019 by greenman3610

            This is a re-post from Yale Climate Connections

            This month’s “This is Not Cool” original video, produced by independent videographer and YCC regular contributor Peter Sinclair, explores the creative science munication initiatives of four different scientists.

            Ecohydrologist, researcher, and science storyteller Emily Fairfax of the University of Colorado studies the intersection of water and ecosystems. “It’s very important that my science has an impact in the world,” Fairfax says. “I take all my data and try to send it out to the public in very pelling ways.” She recalls being “so scared of all the jargon” earlier in her career: “I didn’t want to say a lot of different words, because what if I say them wrong? What if I use them wrong?”

            Working on beavers and their forest environment, she decided to shorten her story to one sentence: “And that was that ‘beaver ponds persist through wildfires.'” If nothing else, she wanted her audience to leave with at least that message firmly in mind. With her infectious enthusiasm, the video shows a toy beaver persisting through a wildfire and then boosting an “I’m Okay!!” flag to assure fearful viewers that the beaver survives.

            The Sinclair video also delves into the creative painting of glaciologist and artist Jill Pelto in remote glacial environments. Her scientist-father long encouraged her to include data in her art work after a field season in the North Cascades in Washington.

            One-time cartoonist and founder of the Skeptical Science website John Cook, now at George Mason University in Virginia, describes how he uses cartoons to make climate change information more accessible. “I could be the first scientist to ever calculate the P value of a cartoon’s funniness,” Cook says, adding that the cartoons are “statistically significant and funny.”

            Cook ran an experiment to test whether logic-based or humor-based corrections to climate misinformation were more effective, and “more importantly, do either of them work.” Cook says both “significantly neutralize misinformation, but the cartoons get an order of magnitude more shares than the logic-based.”

            Beleaguered journalism interests seek to aid ailing planet

            Posted on 27 May 2019 by Guest Author

            This is a re-post from Yale Climate Connections by Bud Ward

            Let’s buy for a moment the well-traveled viewpoint that the news media like nothing better than a good crisis. Nothing like a crisis, and better yet two, to kick reporters’ and editors’, let alone media bean counters’, adrenaline into overdrive. Bring on the banner headlines, the grit and joy of covering someone else’s disasters up-close and personal, perhaps even a greater shot at one of journalism’s more glamorous prizes or awards.

            But what, one might ask, when the crisis is not someone else’s, but rather a crisis in the house of journalism itself? As with the current decades-old and decades-more-to-e demise of the subscriber- and advertiser-paid business model? What if, one well might wonder, the crisis is in journalism itself?


            And to pound the dilemma at hand, what if the crisis in journalism es during an equally, and by all accounts even more serious (truly existential?) confounding crisis? As in misery loves pany.

            Take the climate change crisis as Exhibit A.

            As luck would have it – bad luck, that is – the climate change crisis as we understand it, and as we don’t yet fully understand it, has been occurring and will continue to occur during a time of crisis for responsible journalism. Oh darn.

            Journalism gurus pretty much accept that the ongoing crises of change surrounding and overwhelming many news enterprises will go on for a number of decades before, one hopes, we can all adapt to where it ends up. We can be pretty certain that our kids, and also theirs, will be dealing with this snowballing news/information dilemma for years, probably decades, to e.

            The same, of course, applies to what many experts now feel can only fairly be characterized as a “climate crisis.” Again, as with journalism, it’s a crisis of our own making.

            It’s not like there aren’t serious efforts to help mitigate the long-term harm, to avoid the worst possible impacts. And we can take fort that that applies, at least for now, to both journalism and to climate change.

            Why school strikers are guest editing Climate Home News 

            (Photo: Pixabay)

            Over the ing weeks (or months – let’s see how it goes) Climate Home News will host reporting, personal reflections and mentary written by a group of young people who have inspired the world.

            It’s normal for us to host mentary from activists. But this is something different. Something we would never normally do. It’s an open offer to a group to use our site as a platform to express their ideas.

            We aren’t doing it because we endorse everything the school strikes or Fridays for Future movement says, does or calls for. We are doing it because it’s our job to bring you the full picture.

            Climate change is the archetypal issue of intergenerational justice. As the population ages in many countries around the world, the balance of power between young and old is being increasingly skewed. Given the plexion of the media, it is fair to question whether their voices and interests are being represented here.

            These young people have shown they are masters of disruptive forms of social media and protest. In March, just a few months after forming, they held a global strike that surpassed every organised climate rally held before it. They achieved this with no pre-existing organisational apparatus, real funding or control of traditional media platforms. They are worth listening to.

            Introducing a new citizens initiative for carbon pricing in Europe

            Posted on 22 May 2019 by BaerbelW

            A new European Citizens’ Initiative (ECI) called “The fast, fair and effective solution to climate changewas launched on May 6. The proposal asks that the European mission introduce a carbon-pricing policy known as Carbon Fee and Dividend at the European Union level. The European mission registered the proposal earlier this month.

            Organizers behind the initiative now have one year until May 6, 2020 to gather the 1 million signatures needed for the European mission to consider the proposal.

            Scientists and economists agree: Putting an increasing price on pollution and giving the returns to households works. A steadily increasing price on fossil fuels will reduce pollution by leading panies and consumers to choose cleaner, cheaper options. All money collected would be returned fairly and for example every month to citizens as a dividend. Most low- and middle-ine families will be better off by this policy.

            The European Citizens' Initiative is a democratic instrument that enables every European citizen to shape policy by submitting a legislative proposal. If at least one million signatures are collected for a citizens' initiative, the mission has to examine the proposal and indicate the steps it will take.

            "We're at a turning point in history," says Brigitte Van Gerven, spokesperson for the Initiative. "After years of apathy for the climate problem, people have awakened, thanks to the actions of Greta Thunberg and the climate strikers. The challenge now is to convert this energy into a strong and ambitious climate policy."

            As a policy to reduce greenhouse gas emissions, Carbon Fee and Dividend was implemented earlier this year in Canada, where citizens have already received their “Climate Action Incentive” checks. In the United States, carbon-fee-and-dividend legislation has been introduced by members of both parties as the Energy Innovation and Carbon Dividend Act.

            The policy is a concrete, realistic and financially feasible policy that is budget neutral for the government. Moreover, it is socially just, since it is not a tax increase, but a green tax shift - a redistribution from those who pollute a lot to those who pollute less.

            As concern grows over human-induced climate change, many scientists are looking back through Earth’s history to events that can shed light on changes occurring today. Analyzing how the planet’s climate system has changed in the past improves our understanding of how it may behave in the future.

            It is now clear from these studies that abrupt warming events are built into Earth’s climate system. They have occurred when disturbances in carbon storage at Earth’s surface released greenhouse gases into the atmosphere. One of the grand challenges for climate scientists like me is to determine where these releases came from before humans were present, and what triggered them. Importantly, we want to know if such an event could happen again.

            In a recently published study, my colleagues Katie Harazin, Nadine Krupinski and I discovered that at the end of the last glacial era, about 20,000 years ago, carbon dioxide was released into the ocean from geologic reservoirs located on the seafloor when the oceans began to warm.

            This finding is a potential game-changer. Naturally occurring reservoirs of carbon in the modern ocean could be disturbed again, with potentially serious effects to Earth’s oceans and climate.

            Earth has cycled between ice ages (low points) and warm interglacial periods over the past 800,000 years. But current climatic warming is occurring much faster than past warming events. NASA

            12 excuses for climate inaction and how to refute them

            Using moral clarity to counter defeatism around the climate crisis.


            There’s a reason why the 16-year-old Swedish climate activist Greta Thunberg has successfully goaded powerful politicians into long-overdue climate action in just six months.

            Thunberg, who is on the autism spectrum, has bee a moral authority. Again and again, she’s clearly articulated how adults have shamefully abdicated their basic duties to protect today’s children and future generations from pounding climate catastrophe. “This ongoing irresponsible behavior will no doubt be remembered in history as one of the greatest failures of humankind,” she told the British Parliament.

            “You only talk about moving forward with the same bad ideas that got us into this mess, even when the only sensible thing to do is pull the emergency brake. You are not mature enough to tell it like is. Even that burden you leave to us children,” she declared at the United Nations.

            Her ability to sway politicians and the public, in speeches and through the school strike movement, is now evident: European leaders have called for aggressive new carbon emissions reductions, citing her movement.

            Fortunately, Thunberg is just one of many great minds helping us summon moral clarity to address the tricky problem of framing the climate crisis. That includes the writers David Wallace-Wells, George Monbiot, and Anand Giridharadas; the historian Jill Lepore; and Rep. Alexandria Ocasio-Cortez (D-NY), among many others.

            As we dump more carbon into the atmosphere and the planet cooks, their arguments about what we’re up against — and why we must act now — are essential to cutting through the ties that keep us quiescent.

            These thinkers have inspired us to overe our own psychological roadblocks in facing the climate crisis. The words of writer James Baldwin are helpful here too: “Not everything that is faced can be changed. But nothing can be changed until it is faced.”

             Drawing from these and other wells of wisdom, we’ve put together 12 short answers to some of the most stymying questions to help you work through climate despair, cynicism, defeatism, and paralysis. We can’t delay any more; it’s past time for productive panic.

            IPCC Updates Methodology for Greenhouse Gas Inventories

            Posted on 14 May 2019 by Guest Author

            KYOTO, Japan, May 13 – The Intergovernmental Panel on Climate Change (IPCC) released on Monday an update to its methodology used by governments to estimate their greenhouse gas emissions and removals.

            Governments are required to report their national greenhouse gas inventories — prising estimates of greenhouse gas emissions and removals — to the United Nations Framework Convention on Climate Change (UNFCCC) including under processes such as the Kyoto Protocol and Paris Agreement.

            The updated IPCC methodology improves this transparency and reporting process by ensuring that the methodology used to determine these inventories is based on the latest science.

            The new report, the 2019 Refinement to the 2006 IPCC Guidelines on National Greenhouse Gas Inventories (2019 Refinement), was prepared by the IPCC’s Task Force on National Greenhouse Gas Inventories (TFI). A plenary session of the IPCC Panel in Kyoto, Japan, adopted the report’s Overview Chapter and accepted the main report.

            “The 2019 Refinement provides an updated and sound scientific basis for supporting the preparation and continuous improvement of national greenhouse gas inventories,” said Kiyoto Tanabe, Co-Chair of the TFI.

            The 2019 Refinement provides supplementary methodologies to estimate sources that produce emissions of greenhouse gases and sinks that absorb these gases. It also addresses gaps in the science that were identified, new technologies and production processes have emerged, or for sources and sinks that were not included in the 2006 IPCC Guidelines.

            It also provides updated values of some emission factors used to link the emission of a greenhouse gas for a particular source to the amount of activity causing the emission. Updates are provided where authors identified significant differences from values in the 2006 IPCC Guidelines.

            Over 280 scientists and experts worked on the 2019 Refinement to produce many changes to the general guidance as well as methodologies for four sectors: energy; industrial processes and product use; agriculture, forestry and other land use; and waste.

            Inspiring, not depressing, film fest messages

            Posted on 13 May 2019 by Guest Author

            This is a re-post from Yale Climate Connections by Daisy Simmons

            NEVADA CITY, CALIF. The mood at the 2019 Wild & Scenic Film Festival was brighter than one might expect from an event riddled with reminders of the perils of living in these times, from catastrophic wildfire to loss of biodiversity. But that’s the point of the SYRCL-produced affair: To inspire personal action, not just depress the audience.

            With more than 150 documentary films screening at 10 different venues, and supported by 700 volunteers, the lineup featured a number of memorable films tackling difficult climate change issues.

            Of these, several key themes emerged, but none so palpable as the sense that climate change is more than imminent; its impacts are already being painfully personal here.

            This festival took place just 50 miles away from Paradise, California, which just two months prior had been destroyed by the most destructive fire in state history. With 200 towns across the state now flagged as highly vulnerable to fire, too, it’s little wonder that fire-related films were met with full-house audiences, including for the late-night sessions with panels featuring scientists, filmmakers, and local officials.

            In addition to harrowing scenes of fire, many films covered other personal, disturbing new realities, like worsening effects of air pollution on children’s health, or the town at risk of disappearing as sea levels rise. Still, most ended with a message of hope, shining the light on ways forward that, unlike in years past, ask viewers to rethink how we live, rather than urging purely tactical actions like recycling or eating less meat.

            Also of note was a clear effort to include indigenous voices throughout the festival, from the opening ceremony featuring local Nisenan Tribal Council members, to the more than a dozen films highlighting indigenous wisdom on issues like managing fire and preserving biodiversity.

            Add these memorable climate films to your watch-list

            The main festival is over, but there are still ways to watch some of the highlighted climate feature-length films, whether by renting them online, or attending Wild & Scenic On Tour, which takes place throughout the year in around 230 locations globally.

            Following are remendations for your next climate-documentary date night:

            Proposal to spend 25% of EU budget on climate change

            Schoolchildren have been protesting climate change inaction in recent months across Europe REUTERS

            Eight European countries have called for an ambitious strategy to tackle climate change – and to spend a quarter of the entire EU budget on fighting it.

            The joint statement says the EU should have net-zero greenhouse gas emissions by 2050 "at the latest".

            It was signed by France, Belgium, Denmark, Luxemburg, Netherlands, Portugal, Spain, and Sweden.

            The group says their plan can "go hand in hand with prosperity" and "set an example for other countries to follow."

            The position paper es ahead of a major summit of European leaders in the Romanian city of Sibiu, beginning on Thursday, which will discuss the future of Europe and the EU's strategy for the next five years.

            But not everyone is on board - there are 28 countries in the EU, and several of those absent from the joint position statement are significant players - including Germany.
