Record-breaking European heat wave heads north, massive melting likely in Arctic – “This actually primes things for more sea ice loss later, on the order of weeks”

By Bob Henson 29 July 2019 (Weather Underground) – Over the next few days, meltwater will cascade across the Greenland Ice Sheet, and sea ice will dissolve into the Arctic Ocean in amounts that could be unprecedented for late July and early August. The same air mass that led to the sharpest, hottest heat wave ever […]

Unit 2 of Millstone Power Plant near New London was shut down on 12 August 2012 after temperatures in the sound exceeded 75 degrees for 24 hours, the maximum temperature at which the nuclear power plant has permits to extract cooling water for the unit.

Nuclear power, once seen as impervious to global warming, threatened by heat waves – “You need to solve global warming for nuclear plants to survive”

By Alan Neuhauser 1 July 2019 (US News) – There’s a reason nuclear plants are built close to water. Harnessing the enormous power of nuclear fission, plants generate steam, which shoots through pipes to spin a turbine that generates massive amounts of electricity. To keep from getting dangerously hot, the plants suck up surrounding water […]

Stability diagram of the West Antarctic Ice Sheet (WAIS), rate R versus duration T of mass addition with unstable regime in red and stable regime in blue. Interpolation of the field is based on the conducted ensemble of stabilization experiments (gray circles). The critical threshold Rc (white curve) of stabilization is approximated by function given at the top right corner. White stars highlight simulations that share the same total amount of deposited mass (M = 8000 Gt), added at differing rate and duration, showing that the combination of both determines potential stabilization.

Adding 8 trillion tons of artificial snow to the West Antarctic Ice Sheet could stop it from collapsing – “The fundamental trade-off is whether we as humanity want to sacrifice Antarctica to save the currently inhabited coastal regions”

By Katherine J. Wu 17 July 2019 (PBS) – Gird your loins, humans: The time has come to turn part of the South Pole into our own giant snow globe. Or has it? In a study published today in the journal Science Advances, a team of German researchers suggests that dumping 8 trillion tons of artificial snow onto […]

Example of coastal flooding in Alamitos Bay, California with 0.25 m of sea level rise and storms. This example illustrate that there are locations with significant flood risks for small amounts of sea level rise when storms are considered. Graphic: Barnard, et al., 2019 / Scientific Reports

Trump officials deleting mentions of “climate change” from U.S. Geological Survey press releases – “It’s an insult to the science”

By Scott Waldman 8 July 2019 (Science) – A March news release from the U.S. Geological Survey (USGS) touted a new study that could be useful for infrastructure planning along the California coastline. At least that’s how President Donald Trump’s administration conveyed it. The news release hardly stood out. It focused on the methodology of […]

Three islands disappeared in the past year – The same forces put coastlines around the world at risk – “The sooner we start thinking about this, the less painful it’s going to be”

By Denise Chow 9 June 2019 (NBC News) – Anote Tong can remember when Tebunginako, on the central Pacific island nation of Kiribati, was a thriving village. But beginning in the 1970s, the tide started inching closer to the houses in the village. Over the years, as strong winds whipped up monster waves and climate […]

Video: New York is building a wall to hold back the ocean

10 June 2019 (Vox) – Climate change is leading to increasingly violent storms. Can seawalls hold back floods? Staten Island recently received funding for a nearly 5-mile-long seawall to protect its coast. But the plan raises a lot of questions. We’re living in a dangerously dynamic world: Hurricanes are getting worse, wildfires are rampant in […]

Fears Pacific nuclear bomb waste site is leaking – “We pray that the Runit dome does not eventually become our coffin”

26 May 2019 (AFP) – As nuclear explosions go, the U.S. “Cactus” bomb test in May 1958 was relatively small — but it has left a lasting legacy for the Marshall Islands in a dome-shaped radioactive dump. The dome — described by a UN chief Antonio Guterres as “a kind of coffin” — was built […]

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 […]
