Oil and Gas Emissions a Major Contributor to Bad Ozone Days: Colorado’s northern Front Range focus of new study

Oil and Gas Emissions a Major Contributor to Bad Ozone Days: Colorado’s northern Front Range focus of new study FRIDAY, NOVEMBER 3, 2017 “The high ozone levels we observed on days when oil and gas activity was a primary contributor underscore the importance of better quantifying the contribution from oil and gas operations,” Cheadle said. “That understanding could support strategies …

IPCC visuals are largely on threats, framed as distant in time and space, with minimal attention to who was impacted or needed to take adaption actions or adopt responsibility, rather than rather than goals to be achieved

with minimal attention to who was impacted or needed to take adaption actions or adopt responsibility The visual framing of climate change impacts and adaptation in the IPCC assessment reports Climatic Change Figures and graphics in reports by the Intergovernmental Panel on Climate Change (IPCC) “(still) focus primarily on showing that climate change is real and a problem, with little …

Cornell University study indicates US fracking is responsible for over half of the sizeable rise in global methane emissions between 2008 and 2014

David Roberts, Vox, Aug 2019. Methane doesn’t stay in the atmosphere as long as CO2 and is reabsorbed into terrestrial cycles via chemical reactions within 12 years or so. But while it’s up there, it’s much more potent, trapping heat at roughly 84 times the rate of CO2. Scientists estimate that around 25 percent of current global warming traces to methane. 63 percent of …

We are 50 to 100 years ahead of schedule with the slowdown of the Gulf Stream and ocean circulation pattern,’ says climate scientist Michael Mann

By Peter Sinclair, Thursday, August 15, 2019 A stubborn blue spot of cool ocean temperatures stands out like the proverbial sore thumb in a recent NASA image of the warming world – a circle of cool blue on a planet increasingly shaded in hot red. A region of the North Atlantic south of Greenland has experienced some of its coldest temperatures …

Rising water stress will affect plants: if the water potential and vapor pressure are larger in the atmosphere – water will dissipate faster and stronger from soil and plants

The increased growth rate of plants seen worldwide in response to rising CO2 levels – a phenomenon known as “global greening” – could be stalled by growing water stress, a study finds. Global warming is driving changes to water vapour levels, the research finds, which could, in turn, be affecting the rate of plant photosynthesis – the process underpinning plant growth. Article …

Climate change ‘contrarians’ get 49% more media coverage than leading scientists

If you have a yearning for abundant media coverage, presenting yourself as an expert on global warming while disputing the science is a great way to do it. A study in Nature Communications reveals just how much extra coverage so-called climate contrarians get, at least in the English language media, compared to those with genuine expertise. Scientists are overwhelmingly convinced the world …

Greenland’s ice loss has increased six-fold since the 80s. Now, over the last week, Greenland shed more than 60 billion tons of ice, enough to cover the state of Florida in nearly 5 inches of water, reaching rates scientists didn’t expect to see until the next century

By Maddie Stone, Motherboard, Aug 7 2019 Greenland is losing its ice. The rate of loss has increased sixfold since the 1980s, per a paper published earlier this year. Over the last week, Greenland shed more than 60 billion tons of ice as a heat wave enveloped the Arctic island, triggering melting on a scale not seen since 2012. From July 31 …

Attribution science for tornadoes and a range of other physical events

The figure below shows how well the effects of climate change on different extreme events are understood. It ranks each type of extreme event based on how well the effects of climate change are understood (the x-axis) and on the extent to which any individual event can be attributed to climate change (the y-axis). Understanding and attribution of climate change …

Study finds substantial warming in atmospheric rivers. Also beliefs about climate change in the aftermath of extreme flooding

Justin Gillis, the former NYT environment reporter, has written an opinion piece for the paper noting that the six US states where policies have been adopted requiring the elimination of CO2 emissions from power grids happen to be ones where the Democrats have taken full control of state government: “I think the trend holds important lessons for the Democratic Party. …

May 2019 science and impact updates

Substantial increase in minimum lake surface temperatures under climate change  (Climate Change) The average surface temperature of European lakes has risen by 0.35C per decade since the early 1970s, a new study finds. The researchers analysed observational data for 1973-2014 from eight European lakes, finding rising annual and summer average temperatures – as well as increases in annual minimum lake surface …
