Carbon dioxide levels in atmosphere hit record high in May 2019

4 June 2019 (NOAA) – Atmospheric carbon dioxide continued its rapid rise in 2019, with the average for May peaking at 414.7 parts per million (ppm) at NOAA’s Mauna Loa Atmospheric Baseline Observatory. The measurement is the highest seasonal peak recorded in 61 years of observations on top of Hawaii’s largest volcano and the seventh consecutive […]

Flooded farms in the U.S. Midwest can’t plant crops – Corn and soybean acres not planted at record high – “The frequency of these disasters, I can’t say we’ve experienced anything like this since I’ve been working in agriculture”

By Michael J. Coren 30 May 2019 (Quartz) – The angst on farmer Twitter is palpable. Across the Midwest, torrential rains have soaked the fields, leaving the sodden soil unsuitable for planting millions of acres with corn, soybeans, and other crops, presaging a terrible harvest. Seeds are usually in the ground this time of year. […]

Graph of the Day: NOAA Annual Greenhouse Gas Index, 1700-2018

30 May 2019 (Desdemona Despair) – Last week, the NOAA Earth System Research Laboratory posted its annual update to the NOAA Annual Greenhouse Gas Index (AGGI), which measures the climate-warming influence of long-lived trace gases, including carbon dioxide and methane. To nobody’s surprise, the AGGI continued its inexorable rise in 2018 because, for another year, […]

The methane detectives: On the trail of a global warming mystery – “The bottom line is that methane is going up and doesn’t look like it will stop anytime soon”

By Jonathan Mingle 13 May 2019 (Undark) – Every week, dozens of metal flasks arrive at NOAA’s Earth System Research Laboratory in Boulder, Colorado, each one loaded with air from a distant corner of the world. Research chemist Ed Dlugokencky and his colleagues in the Global Monitoring Division catalog the canisters, and then use a series of […]

The wealth detective who finds the hidden money of the super rich – “The bottom half of Americans combined have a negative net worth”

By Ben Steverman 23 May 2019 (Bloomberg Businessweek) — Gabriel Zucman started his first real job the Monday after the collapse of Lehman Brothers. Fresh from the Paris School of Economics, where he’d studied with a professor named Thomas Piketty, Zucman had lined up an internship at Exane, the French brokerage firm. He joined a […]

Louisiana unveils ambitious plan to help people get out of the way of climate change

By Christopher Flavelle and Mira Rojanasakul 15 May 2019 (Bloomberg) – Gerard Braud has no plans to leave his handsome Creole-style house with its 15-foot-high front porch on the north shore of Lake Pontchartrain, a short drive from New Orleans. “Peacefulness and tranquility” is how he explains the appeal of living here. Except that thanks […]

Exponential growth in impacts from abrupt climate change

By Nick Humphrey 2 May 2019 (Patreon) – I get asked a lot about what the future holds. I discussed the projections of global average temperature and sea level rise in an upcoming interview on Radio Ecoshock (will be posted next week). However, while trying to write an article on this, I found myself frustrated […]

Projected change in population density in Ethiopia by 2050 under a pessimistic climate change scenario. As climate change worsens even moderately, it could cause water shortages in Ethiopia severe enough to prompt 1.5 million Ethiopians to migrate by 2050. They’ll most likely move out of the northern highlands and Addis Ababa into the southern highlands and Ahmar Mountains. Addis Ababa lies at the center of Ethiopia’s agricultural region, and lower crop yields will result in movement out of the urban center, which is currently the hub of the country’s economic development.

Get ready for tens of millions of climate refugees

By Susan Cosier 24 April 2019 (Technology Review) – In 2006, the British economist Nicholas Stern warned that one of the biggest dangers of climate change would be mass migration. “Climate-related shocks have sparked violent conflict in the past,” he wrote, “and conflict is a serious risk in areas such as West Africa, the Nile […]

Summer extremes of 2018 linked to stalled giant waves in jet stream

29 April 2019 (PIK) – Record breaking heatwaves and droughts in North America and Western Europe, torrential rainfalls and floods in South-East Europe and Japan – the summer of 2018 brought a series of extreme weather events that occurred almost simultaneously around the Northern Hemisphere in June and July. These extremes had something in common, […]

Scientists race against time to find out if Antarctica’s Thwaites Glacier is doomed – “This is where rapid change is really happening, and we’re actually standing and looking at the bit that’s rapidly changing”

By Carolyn Beeler 13 May 2019 (PRI) – Peter Sheehan, an oceanographer on the Nathaniel B. Palmer, was one of the first people on Earth to get this view of Thwaites Glacier — the part that juts out to sea. He’s pored over plenty of Google images of ice shelves, but there’s nothing like the […]
