Nunavut is warmer than Victoria in long, hot summer across the Arctic – “It’s really quite spectacular. This is unprecedented.”

By Bob Weber 15 July 2019 (The Canadian Press) – Weather watchers are focused on the world’s most northerly community, which is in the middle of a record-breaking heat wave. “It’s really quite spectacular,” said David Phillips, Environment Canada’s chief climatologist. “This is unprecedented.” The weather agency confirmed that Canadian Forces Station Alert hit a record […]

Scientists declare Masai giraffes “Endangered” – “We have to regulate the international giraffe trade or risk losing one of our planet’s most remarkable animals”

WASHINGTON, 11 July 2019 (Center for Biological Diversity) – Highlighting the need for global action to fight giraffes’ silent extinction, a body of scientific experts today declared giraffes in Kenya and Tanzania — called Masai giraffes — endangered. Masai giraffes, one of nine giraffe subspecies, had long been considered a key population for the species. But […]

Impact of the Powering Past Coal Alliance (PPCA) pledges. To keep global warming within 1.5 °C of pre-industrial levels, there needs to be a substantial decline in the use of coal power by 2030 and in most scenarios, complete cessation by 2050. Graphic: Jewell, et al., 2019 / Nature Climate Change

Current coal phase-out pledges are insufficient to hit Paris climate goal

27 June 2019 (Chalmers University of Technology) – ​The Powering Past Coal Alliance, or PPCA, is a coalition of 30 countries and 22 cities and states that aims to phase out unabated coal power. But analysis led by Chalmers University of Technology, Sweden, published in Nature Climate Change, shows that members mainly pledge to close […]

Humanity’s climate “carbon budget” dwindling fast – At current CO2 emission rates the budget will be exhausted in less than 14 years – “The trillion-dollar question is how much of a carbon budget do we have left?”

17 July 2019 (AFP) – The concept of a carbon budget is dead simple: figure out how much CO2 humanity can pump into the atmosphere without pushing Earth’s surface temperature beyond a dangerous threshold. [cf. What Counts for Our Climate: Carbon Budgets Untangled and Budgeting for our future climate. –Des] The 2015 Paris climate treaty […]

June 2019: Earth’s hottest June on record and greatest June heat wave in European history

By Dr. Jeff Masters 18 July 2019 (Weather Underground) – June 2019 was the planet’s warmest June since record keeping began in 1880, said NOAA’s National Centers for Environmental Information (NCEI) on Tuesday. NASA also rated June 2019 as the warmest June on record, well of ahead of the previous record set in 2015. The global heat in June […]

“Committed” CO2 emissions jeopardize international climate goals – Existing, planned fossil fuel-burning infrastructure must be retired early, replaced – “Without such radical changes, we fear the aspirations of the Paris agreement are already at risk”

IRVINE, California, 1 July 2019 (UCI News) – The nations that have signed agreements to stabilize the global mean temperature by 2050 will fail to meet their goals unless existing fossil fuel-burning infrastructure around the world is retired early, according to a study [pdf] – published today in Nature – by researchers at the University […]

Expert reaction to study looking at trees, carbon storage, and climate change – “It is time to stop suggesting there is a ‘nature-based solution’ to ongoing fossil fuel use. There isn’t. Sorry.”

4 July 2019 (Science Media Centre) – A new study, published in Science, reports on the capacity for trees to reduce atmospheric carbon levels. Dr James Borrell, Researcher at the Royal Botanic Gardens, Kew, said: “Global forest restoration clearly has remarkable potential to address climate change, but restoring forest on this scale is a significant […]

Global warming drives 8X increase in California summer wildfires and 5X increase in area burned – “The ability of dry fuels to promote large fires is nonlinear”

By Kevin Krajick 15 July 2019 (Columbia University) – Against a backdrop of long-term rises in temperature in recent decades, California has seen ever higher spikes in seasonal wildfires, and, in the last two years, a string of disastrous, record-setting blazes. This has led scientists, politicians and media to ponder: what role might warming climate be […]

Athlete vs. heat: Scorching conditions are increasingly common at sporting events, creating risks and challenges for athletes – “It’ll be the hottest Summer Olympics in history”

By Rick Maese 15 July 2019 LOVELL CANYON, Nevada (The Washington Post) – It was 73 degrees and the early-morning sun was still rising over the Mojave Desert as nearly six dozen long-distance runners gathered at the start line and anxiously watched numbers tick down on the digital clock overhead. “Make sure that you’re staying […]

Melting of Himalaya glaciers has doubled in recent years

By Kevin Krajick 19 June 2019 (Columbia University) – A newly comprehensive study shows that melting of Himalayan glaciers caused by rising temperatures has accelerated dramatically since the start of the 21st century. The analysis, spanning 40 years of satellite observations across India, China, Nepal and Bhutan, indicates that glaciers have been losing the equivalent of more than […]
