Editorial cartoonists lampoon, praise Green New Deal

This is a re-post from Yale Climate Connections by Michael Svoboda Like journalists, opinion writers, and TV newscasters and commentators, political cartoonists were quick to respond to the Green New Deal (GND) climate change initiative put out in early February by two liberal northeastern Democrats in the U.S. Senate and House of Representatives. But there were striking differences in

Asteroid to hit Earth in August 2046 – Emergency IPCC UN panel formed

Scientists have today revealed that thanks to new radar imaging system, a 20 km-wide asteroid is on a probable collision course with earth and they calculate it has an 85% probability of striking the planet between 23-25 August, 2046. Observers from centers in Chile to Finland have confirmed the observations and are urging governments worldwide to begin efforts to avoid a global catastrophe. The plan is to mobilize industry and research together

US and Latin America Take Top Spots Again in the Growing Solar Tracker Market

The global solar PV tracker market grew by 20 percent last year, and the U.S. and Latin America remained the largest markets for tracker technology. Wood Mackenzie Power & Renewables breaks down the global tracker market by megawatts shipped and by region in a new report. “PV tracker shipments exceeded expectations and surpassed 20 gigawatts last year, with 36 percent year-over

First successful model simulation of the past 3 million years of climate change

Guest post by Matteo Willeit, Potsdam Institute for Climate Impact Research A new study published in Science Advances shows that the main features of natural climate variability over the last 3 million years can be reproduced with an efficient model of the Earth system. The Quaternary is the most recent geological Period, covering the past ~2.6 million years. It is defined by the presence of glacial-interglacial cycles associated with the cyclic

3 clean energy myths that can lead to a productive climate conversation

This is a re-post from Yale Climate Connections by Karin Kirk Energy use is the biggest cause of climate change, and it’s the first place to enact meaningful strategies to lower greenhouse emissions. It’s also a smart angle for talking about climate change, because it’s easy to find agreement on issues like improving energy efficiency, reducing pollution, cleaning up our energy supply, and reducing reliance on unstable

Alpine glaciers: Another decade of loss

Guest Commentary by Mauri Pelto (Nichols College) Preliminary data reported from the reference glaciers of the World Glacier Monitoring Service (WGMS) in 2018 from Argentina, Austria, China, France, Italy, Kazakhstan, Kyrgyzstan, Nepal, Norway, Russia, Sweden, Switzerland and United States indicate that 2018 will be the 30th consecutive year of significant negative annual balance (> -200mm); with a mean balance of -1247 mm for the 25 reporting reference glaciers, with only one glacier reporting a positive mass balance (WGMS, 2018).

Wallace Broecker: Scientists memorialize a titan of climate science

This is a re-post from Yale Climate Connections by Bud Ward Wally Broecker, photographed around 2010 (Credit: Bruce Gilbert, via Lamont-Doherty Earth Observatory) The climate science community has lost one of the real titans of its field. Geochemist Wallace Broecker – known as “Wally” – passed away February 18 in New York at age 87 of congestive heart failure. A pioneer in identifying Earth’s warming as a result of human emissions of carbon dioxide, Broecker is widely credited with introducing in the 1970s the term “global warming.” A 1996

New rebuttal to the myth ‘Holistic Management can reverse Climate Change’

This is the new Basic rebuttal to the myth ‘Holistic Management can reverse Climate Change’. There’s also an Advanced rebuttal. The Myth: Holistic Management can reverse Climate Change “Holistic management as a planned grazing strategy is able to reverse desertification and sequester atmospheric carbon dioxide into soil, reducing atmospheric carbon dioxide levels to pre-industrial levels in a period of forty years.” (Allan Savory, 2014) The Rebuttal: Holistic Management is a form of grazing management that has become popularised in recent years by Allan Savory, founder of the Savory Institute. The management technique has been subject of international attention, mainly due to the

New Ocean Heat Content Histories

Guest commentary from Laure Zanna (U. Oxford) and G. Jake Gebbie (WHOI) Two recent papers, Zanna et al. (2019) (hereafter ZKGIH19) and Gebbie & Huybers (2019) (hereafter GH19), independently reconstructed ocean heat content (OHC) changes prior to the instrumentally-based records (which start ~1950). The goals (and methodologies) of the two papers were quite different – ZKGIH19 investigated regional patterns of ocean warming and thermal sea level rise, while GH19 analyzed the long-term memory of

What the 2018 climate assessments say about the Gulf Stream System slowdown

Last year, twenty thousand peer reviewed studies on ‘climate change’ were published. No single person can keep track of all those – you’d have to read 55 papers every single day. (And, by the way, that huge mass of publications is why climate deniers will always find something to cherry-pick that suits their agenda.) That is why climate assessments are so important, where a lot of scientists pool their expertise and

Update day

So Wednesday was temperature series update day. The HadCRUT4, NOAA NCEI and GISTEMP time-series were all updated through to the end of 2018 (slightly delayed by the federal government shutdown). Berkeley Earth and the MSU satellite datasets were updated a couple of weeks ago. And that means that everyone gets to add a single additional annual
