Satellite view of the Conger/Glenzer (Bowman Island) ice shelf collapse in March 2022. Scientists are concerned because the ice shelf collapsed in East Antarctica, an area that had long been thought to be stable. The collapse in March 2022 was the first time scientists have ever seen an ice shelf collapse in this cold area of Antarctica. Photo: NASA / AP

Thinning Antarctic ice shelf finally crumbles after extreme heatwave – “The Glenzer Conger ice shelf presumably had been there for thousands of years, and it’s never going to be there again”

By Isla Binnie 25 March 2022 (Reuters) – An East Antarctica ice shelf disintegrated this month following a period of extreme heat in the region, according to scientists. Satellite images show the 1,200 square-kilometre Conger Ice Shelf collapsed completely on or around March 15. “Possible it hit its tipping point following the #Antarctic #AtmosphericRiver and […]

Australia’s cataclysmic floods raise specter of permanent retreat as towns become uninsurable – Sydney to be hit by another 100mm (4 inches) of rain in four days as bureau warns of flood fatigue – “The taxpayer is now the insurer”

By Sarah Keoghan and Laura Chung 22 March 2022 (SMH) – The Bureau of Meteorology has urged residents in flood-prone areas to remain vigilant as 100 millimetres of rain is forecast for Sydney over the next four days. Senior meteorologist Jackson Browne said the weather bureau was concerned flood-fatigued residents living in at-risk areas may […]

Graph of the Day: Daily high surface temperature at Dome C in Antarctica, 18 March 2022

By Dr. Robert Rohde 21 March 2022 (Twitter) – Heat wave in Antarctica, +38 °C (+68 °F) above normal. That’s not an error, or a typo. The remote research station at Dome C recorded a temperature nearly 40°C above normal for this time of year, beating the previous March record by a startling 20°C. […] […]

Russia’s war on Ukraine threatens climate goals, warns UN chief – “This is madness. Addiction to fossil fuels is mutually assured destruction.”

By Fiona Harvey 21 March 2022 (The Guardian) – The war in Ukraine risks putting global targets on the climate out of reach, the UN secretary general has warned, if countries respond to Russia’s aggression by increasing their use of fossil fuels. António Guterres said the aim of limiting global temperatures to 1.5C above pre-industrial levels, […]

Texas wildfire kills 1, as officials worry extreme drought could worsen conditions – “In the wetter parts of Texas, there will be more fuel, and things will dry out more rapidly”

By Jack Douglas and Jacob Bogage 19 March 2022 CARBON, Texas (The Washington Post) – All Raquel Robles could do was watch the video on her phone, horrified and helpless, as first smoke, then fire, moved up her driveway and then destroyed the house she and her family had lived in for 13 years. Flames […]

Geographical distribution of the measured mass light absorption coefficient (at 365 nm, babs-365, Mm−1, M = 10−6) of water-soluble brown carbon (BrC) in the circum-Arctic. The data dots are plotted at the middle of each sample. The shading was interpolated based on the measurements using the Data-Interpolating Variational Analysis method in the software Ocean Data View. The color range is set as the 10th and 90th percentiles of babs-365. The observed babs-365 of water-soluble BrC at Utqiaġvik (formerly Barrow) from August to September (2012) for PM10 samples (diamond) and at Alert from May to early June (1991) for total suspended samples (square) is also shown for comparison.

Brown carbon from biomass burning imposes strong Arctic warming feedback – “We expect an increasing importance of brown carbon in the warming of the circum-arctic in the future”

18 March 2022 (Max Planck Institute for Chemistry) – Rapid warming in the Arctic and accelerated glacier and sea ice melting have a huge impact on the global environment. Greenhouse gases, such as carbon dioxide, and black carbon aerosols are well-known warming agents. In contrast, atmospheric, light absorbing brown carbon particles belong to the least […]

The Amazon Rainforest is approaching a tipping point beyond which it would become savannah – “When it will be observable, it would likely be too late to stop it”

By Eric Shank 14 March 2022 (Salon) – A vast expanse of unique biological diversity hangs in the balance as the “lungs of the world” approach a tipping point from which there is no recovery. The Amazon Rainforest is losing its ability to regenerate, reported a peer-reviewed study, Monday, in Nature Climate Change. For 10% of all known species on […]

Simulation of 2m temperature anomaly centered over Antarctica on 18 March 2022. Parts of eastern Antarctica saw temperatures hover 70 degrees Fahrenheit (40 Celsius) above normal for more than three days. On 18 March 2022, the surface temperature in Vostok leaped to 0°F (-17.7 Celsius), the warmest it’s been there during March since record keeping began 65 years ago. It broke the previous monthly record by a staggering 27 degrees Fahrenheit (15 Celsius). Graphic: WeatherBell
