Study finds Black and Hispanic Americans are disproportionately exposed to wider temperature swings

22 May 2024 (PNAS Nexus) – Extreme heat can harm human health, but so can extreme temperature swings. Large daily temperature variation (DTV) has been associated with elevated mortality in studies around the world. Trees and other vegetation can lower DTV, as trees reduce temperature through transpiration during the day and also trap long-wave radiation […]

Isle of Wight-size iceberg breaks from Antarctica – “This latest calving reduces the Brunt Ice Shelf to its smallest observed size”

By Jonathan Amos 21 May 2024 (BBC News) – Another big iceberg has broken away from an area of the Antarctic that hosts the UK’s Halley research station. It is the third such block to calve near the base in the past three years. This new one is not quite as large, but still measures […]

Climate change and rapid urbanization worsened the impact of East African rains, scientists say – “We’re likely to see this kind of intensive rainfall happening this season going into the future”

By Carlos Mureithi 23 May 2024 NAIROBI, Kenya (AP) – The impact of the calamitous rains that struck East Africa from March to May was intensified by a mix of climate change and rapid growth of urban areas, an international team of climate scientists said in a study published Friday. The findings come from World Weather Attribution, […]

Hailstorm covers Mexican city with thick ice amid heat wave

24 May 2024 (Reuters) – The unexpected storm surprised locals as hail accumulated up to several feet in some areas, transforming streets into icy rivers. The hailstorm caused widespread damage to some homes, blocking roads and knocking down trees. In the aftermath of the storm, residents were seen shoveling ice and mud in amazement at […]

How “kitty cats” are wrecking the home insurance industry – “What we’ve missed is that it wasn’t a big event that had a big impact, it was a bunch of small surprise events that just added up”

By Jake Bittle 16 May 2024 (Grist) – The rising cost of homeowner’s insurance is now one of the most prominent symptoms of climate change in the United States. Major carriers like State Farm and Allstate have pulled back from offering fire insurance in California, dropping thousands of homeowners from their books, and dozens of small […]

Global daily average temperature anomalies relative to a preindustrial baseline, 1940-2024. Data: Copernicus C3S/ECMWF Era5. Note: Data for 2024 are through February. Preindustrial baseline = 1850-1900. Graphic: The Guardian

We asked 380 climate scientists what they felt about the future – “Sometimes it is almost impossible not to feel hopeless and broken”

By Damian Carrington 8 May 2024 (The Guardian) – “Sometimes it is almost impossible not to feel hopeless and broken,” says the climate scientist Ruth Cerezo-Mota. “After all the flooding, fires, and droughts of the last three years worldwide, all related to climate change, and after the fury of Hurricane Otis in Mexico, my country, […]

Hansen: Comments on global warming acceleration, sulfur emissions, observations – “Acceleration of global warming is now hard to deny”

By James Hansen, Pushker Kharecha, and Makiko Sato 16 May 2024 (Columbia University) – Global temperature (12-month mean) is still rising at 1.56°C relative to 1880-1920 in the GISS analysis through April (Fig. 1). [Robert Rohde reports that it is 1.65°C relative to 1850-1900 in the BerkeleyEarth analysis.] Global temperature is likely to continue to […]

Monthly year-over-year change in atmospheric CO2, 1960-2024. CO2 is measured in parts per million at the Mauna Loa observatory. The largest ever recorded leap in the amount of carbon dioxide in the world’s atmosphere occurred from March 2023 to March 2024. Data: Dr. Xin Lan, NOAA/GML and Dr. Ralph Keeling, Scripps Institution of Oceanography. Graphic: The Guardian

Record-breaking increase in CO2 levels in world’s atmosphere – “We aren’t just breaking records in CO2 concentrations, but also the record in how fast it is rising”

By Oliver Milman 9 May 2024 (The Guardian) – The largest ever recorded leap in the amount of carbon dioxide laden in the world’s atmosphere has just occurred, according to researchers who monitor the relentless accumulation of the primary gas that is heating the planet. The global average concentration of carbon dioxide in March this […]

Diagrams showing parameters for the collapse of the Atlantic Meridional Overturning Circulation (AMOC). (A) The AMOC strength at 1000 m and 26°N, where the yellow shading indicates observed ranges (60, 61). The cyan-colored lines indicate the magnitude of FH. The red arrow indicates the AMOC tipping point (model year 1758; fig. S1, A and B), and the blue sections indicate the 50-year periods used in (B) to (D). Inset: The hosing experiment where fresh water is added to the ocean surface between 20°N and 50°N in the Atlantic Ocean (+FH) and is compensated over the remaining ocean surface (−FH). The black sections indicate the 26°N and 34°S latitudes over which the AMOC strength and freshwater transport (FovS) are determined, respectively. (B to D) AMOC streamfunction (Ψ) and Atlantic meridional heat transport (MHT; see also fig. S2) for model years 1 to 50, 1701 to 1750, and 2151 to 2200. The contours indicate the isolines of Ψ for different values. Graphic: Van Westen, et al., 2024 / Science Advances

Marker for the collapse of key Atlantic current discovered – “We are approaching the tipping point”

By Stephanie Pappas 9 February 2024 (Live Science) – Scientists have discovered a key warning sign before a crucial Atlantic current collapses and plunges the Northern Hemisphere into climate chaos.  The Atlantic Meridional Overturning Circulation (AMOC) carries warm water north from the Southern Hemisphere, where it releases heat and freezes. The freezing process concentrates salt […]

Sweltering heat across Asia in 2024 was 45 times more likely because of climate change, study finds – “Heat is now among the foremost risks in terms of personal health for millions across the world as well as nations’ economic development”

By Sibi Arasu 14 May 2024 BENGALURU, India (AP) – Sizzling heat across Asia and the Middle East in late April that echoed last year’s destructive swelter was made 45 times more likely in some parts of the continent because of human-caused climate change, a study Tuesday found. Scorching temperatures were felt across large swaths of Asia, […]
