Can direct air capture technology save us from global warming? “By the end of the century, DAC could require the equivalent of over half of today’s global energy needs”

By Simon Levey 22 July 2019 (Grantham Institute) – “We’ve fallen in and out of love with outlandish technologies in the hope that they might save us from climate change,” says Dr Ajay Gambhir, Senior Research Fellow at the Grantham Institute – Climate Change and the Environment at Imperial College London. “Some are just unicorns; […]

Where lions once ruled, they are now quietly disappearing – Lion population has declined by 50 percent in 25 years

By Olivia Prentzel 18 July 2019 (National Geographic) – For every lion in the wild, there are 14 African elephants, and there are 15 Western lowland gorillas. There are more rhinos than lions, too. The iconic species has disappeared from 94 percent of its historic range, which once included almost the entire African continent but […]

Wildfires rage in Siberia around the “Mouth of Hell” – Scientist warns fires will accelerate growth of Batagai Depression, a giant gash in the tundra

16 July 2019 (The Siberian Times) – After a month of warm, dry weather and wildfires, the huge crater nicknamed ‘Mouth of Hell’ is now under direct threat. The fear is that flames burning on the rim of the depression will weaken the permafrost and cause a major enlargement of the Batagai or Batagaika ‘megaslump’, […]

76 billion opioid pills: Newly released federal data unmasks the epidemic – “America should brace itself for the harsh reality of the scope of the opioid epidemic”

By Scott Higham, Sari Horwitz, and Steven Rich 16 July 2019 (The Washington Post) – America’s largest drug companies saturated the country with 76 billion oxycodone and hydrocodone pain pills from 2006 through 2012 as the nation’s deadliest drug epidemic spun out of control, according to previously undisclosed company data released as part of the […]

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 […]

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 […]

Combined land and ocean temperature anomalies in June in Europe, 1910-2019. 26–30 June 2019 brought the greatest June heat wave in European history. Hundreds of stations with a long-term period of record (POR) set their all-time June maximum temperature records. Graphic: James P. Galasyn / NOAA

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 […]

World map showing risk assessment of future changes in potential tree cover. (A) Illustration of expected losses in potential tree cover by 2050, under the “business as usual” climate change scenario (RCP 8.5), from the average of three Earth system models commonly used in ecology (cesm1cam5, cesm1bgc, and mohchadgem2es). (B) Quantitative numbers of potential gain and loss are illustrated by bins of 5° along a latitudinal gradient. Graphic: Bastin, et al., 2019 / Science

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 […]
