Portion of West Antarctica twice size of California partially melted in 2016

By James Ayre, Clean Technica, 21 June 2017  A portion of West Antarctica over twice the size of the US state of California partially melted in 2016 as the result of high temperatures brought by an especially pronounced El Niño, compounded by a rapidly warming climate, according to new research published in the journal Nature Communications. While it’s been clear …

7 reasons to be alarmed by record-setting levels of CO2

By Joe Romm, Climate Progress, June 2017:  Trump puts humanity back on track to CO2 levels not seen since it was 5° to 10°F warmer and seas were 75 to 120 feet higher.   Despite the best efforts of the Trump administration to ignore or contradict scientific reality, carbon dioxide levels continue to soar far outside the bounds of what Homo …

Instead of expecting people to understand climate change, reframe the problem entirely and talk about pollution or sensible risk policies or health

“Believe In Climate Change” The Way You Believe In Gravity OR reframe the problem entirely and talk about pollution or sensible risk policies or health By Michael Barnard, Clean Technica, 10 June 2017 There’s a problematic question in journalism and science communication. Various people are asking journalists to stop asking politicians whether they “believe in climate change” and to start …

How scientific causation came to be solidified in the tobacco use vs. lung cancer death rates era, relevance to climate skeptics now

By Seth Miller, see Newsfeed for the whole article, June 2017 Data credit: cancer.org, original image slightly reformatted by me in Tableau Long before research exposed evidence that humans cause global warming, science made another sensational claim — that smoking caused lung cancer.  That case has been proven beyond doubt. But there is a science story from this era that is mostly forgotten: The battle …

Allergy, oak pollen and ragweed seasons growing with climate change

More children could wind up in hospital emergency rooms suffering from allergy-induced asthma if greenhouse gas emissions continue to rise and cause longer oak pollen seasons, according to a new study. The new research finds that if greenhouse gas emissions continue to increase through the end of this century, the oak pollen season in some areas could extend by up …

Declining precipitation in Colorado River Basin worsened by rising temperatures

Scientists found that another factor affected the runoff ratio: temperature. Over the last few centuries, the runoff ratio was reduced when temperatures were warmer. And the influence of temperature strengthened during drier years: When the snowpack was shallow, warm temperatures reduced the runoff ratio more than when the snowpack was deep, further exacerbating drought conditions. The low runoff ratios seen …

Ancient carbon in the tundra, an Arctic carbon-freezer, is melting

By Joe Romm, Climate Progress, 15 May 2017 The permafrost, or tundra, has been a very large carbon freezer. For a very long time, it has had a very low decomposition rate for the carbon-rich plant matter. But we’ve been leaving the freezer door wide open and are witnessing the permafrost being transformed from a long-term carbon locker to a …

Scientists warned the US president about global warming and risks from it 2 years ago

On 5 November 1965 climate scientists summarized the risks associated with rising carbon pollution in a report for Lyndon Baines Johnson. By Dana Nuccitelli in The Guardian  President Lyndon B Johnson in the Oval Sitting Room of the family quarters of the White House. Photograph: Bettmann/Corbis Fifty years ago today, as the American Association for the Advancement of Science highlighted, …

97% or 99.999% agreement by scientists on human-caused climate change? It’s the latter and its 500x different

Reprinted from Clean Technica, July 31st, 2015 by Sandy Dechert James L. Powell, director of the National Physical Sciences Consortium and whistleblower on climate change denial, has a mission to bring media and readers up to date on how many scientists believe people cause climate change. The anthropogenic climate change number is larger than you might think. Dr. Powell has …
