Climate collapse could happen fast – “For a long time, we were within the range of normal. And now we’re really not. And it has happened fast enough that people have a memory of it happening.”

By Lois Parshley 20 July 2023 (The Atlantic) – Ever since some of the earliest projections of climate change were made back in the 1970s, they have been remarkably accurate at predicting the rate at which global temperatures would rise. For decades, climate change has proceeded at roughly the expected pace, says David Armstrong McKay, a […]

Pacific island sea levels rising faster than global average, WMO says – Economic damage in Southwest Pacific due to flooding in 2022 was $8.5 billion, almost triple compared to the previous year

By Gabrielle Tétrault-Farber 17 August 2023 GENEVA (Reuters) – Sea levels in the South-West Pacific are rising faster than the global average, threatening low-lying islands while heat damages marine ecosystems, the U.N. meteorological agency said on Friday. In its State of the Climate in the South-West Pacific 2022 report, the World Meteorological Organization (WMO) said […]

How climate scientists feel about seeing their dire predictions come true – “I used to think, ‘I’m concerned for my children and grandchildren.’ Now it’s to the point where I’m concerned about myself.”

By Corinne Purtill 18 August 2023 (Los Angeles Times) – You are correct. It is, in fact, extremely unusual to be on hurricane watch in Southern California. If Hurricane Hilary continues on the trajectory forecasters are currently predicting, it will be the first tropical storm to make landfall in California since 1939, and only the second one to do […]

Ghost forests: coastal forests dying off as sea-level rise accelerates

By Ginger Zee, Daniel Manzo, and Kelly Livingston 6 July 2023 (ABC News) – As people around the world contend this week with the hottest temperatures ever recorded on Earth, more visual evidence of climate change is emerging with the spread of ghost forests. The globe is naturally warming and seas naturally rise, but greenhouse […]

Humans have pumped so much groundwater that we’ve nudged the earth’s spin – “As a resident of Earth and a father, I’m concerned and surprised to see that pumping groundwater is another source of sea-level rise”

WASHINGTON, 15 June 2023 (AGO) – By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study published in Geophysical Research Letters, AGU’s journal for short-format, high-impact research with […]

What happens to a people when their land disappears – “We could lose our status as a state”

By Jonathan Watts 27 June 2023 (The Guardian) – Small island nations would rather fight than flee, but rising sea levels have prompted apocalyptic legal discussions about whether a state is still a state if its land disappears below the waves. The Pacific Islands Forum, which represents many of the most vulnerable countries, has invited international […]

Land around the U.S. is sinking. Here are some of the fastest areas.

By Kasha Patel 30 May 2023 (The Washington Post) – Imagine Earth’s surface is like a stack of pancakes. The pancakes, or layers of soil and rocks, may appear fairly evenly stacked and fluffy. Over time though, the stack can become compressed, thinner and shorter. Scientists observe this downward motion of land, called land subsidence, […]

Accelerated melting of glaciers in Greenland – Greenland’s glaciers have lost at least 587 cubic km of ice over the last century

26 May 2023 (University of Leeds) – A study has found widespread mass loss of glaciers and ice caps in Greenland since the start of the 20th century. The research provides critical insights into long-term changes to the glaciers and ice caps as a result of climate change, which has contributed about one fifth to […]

WMO annual report highlights continuous advance of climate change – “While greenhouse gas emissions continue to rise and the climate continues to change, populations worldwide continue to be gravely impacted by extreme weather and climate events”

Geneva, 21 April 2023 (WMO) – From mountain peaks to ocean depths, climate change continued its advance in 2022, according to the annual report from the World Meteorological Organization (WMO). Droughts, floods, and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record […]
