India lashed by strongest cyclone ever to hit west coast as it reels from Covid disaster – “This cyclone is a terrible double blow for millions of people in India whose families have been struck down by record Covid infections and deaths”

By Jessie Yeung and Esha Mitra 18 May 2021 NEW DELHI (CNN) – India was slammed on Monday by the strongest storm on record to reach its west coast, hampering authorities’ response to the Covid-19 crisis in some of the country’s hardest-hit regions. Tropical Cyclone Tauktae, a storm with wind speeds equivalent to a high-end Category 3 hurricane that […]

NOAA’s “new normal” climate report is anything but normal – “We’re really seeing the fingerprints of climate change in the new normals”

By Jeff Berardelli 8 May 2021 (CBS News) – Just a quick glance at the new U.S. Climate Normals maps published by the National Oceanic and Atmospheric Administration (NOAA) on Tuesday is enough for most climate scientists to say, “I told you so.” And it’s not just because the maps show a warmer and wetter […]

Earliest tropical storm on record develops in the eastern Pacific

By Haley Brink 9 May 2021 (CNN) – The first tropical storm of the 2021 eastern Pacific hurricane season formed off the southwest coast of Mexico on Sunday. Tropical Storm Andres is the earliest tropical storm to ever form during the satellite era in the eastern Pacific, surpassing Adrian in 2017. Andres also holds the […]

Changes to giant ocean eddies could have “devastating effects” globally – Scientists find “a global-scale reorganization of the ocean’s energy over the past three decades”

By Graham Readfearn 22 April 2021 (The Guardian) – Twirling and meandering ocean currents that help shape the world’s climate have gone through a “global-scale reorganisation” over the past three decades, according to new research. The amount of energy in these ocean currents, which can be from 10km to 100km across and are known as […]

Deep water underneath the Thwaites ice shelf front is lighter than water outside the ice shelf. (A) Map of trough T3 showing the AUV path color coded by latitude. Shaded region indicates the ice shelf front, and black contours are depth contours. (B) Conservative temperature θ (in degrees Celsius) versus absolute salinity SA (in grams per kilogram) for the AUV data points shown in (A), colors as in (A). Contours show potential density (9) relative to 900 m, and blue arrow indicates isopycnal mixing, i.e., water that has the same density but different temperatures and salinities. Green circles in (A) and (B) show the dense saline deep water found in trough T3 discussed in the main text. (C) Absolute salinity SA (in grams per kilogram) as a function of depth for the AUV data in trough T3 and the CTD data (colors indicate station as in Fig. 3). (D) Potential density (in kilograms per cubic meter) as a function of depth for the AUV data in trough T3 and the CTD data (colors indicate station as in Figs. 3 and 4). Red and blue arrows indicate the two deep water masses discussed in the main text from Pine Island Bay and Thwaites Trough. Dissolved oxygen versus θ and SA is shown in fig. S6.

Exploration of ocean currents beneath the “Doomsday Glacier” by an autonomous underwater vehicle – Net melting of 75 cubic km of ice per year means “the glacier is not stable over time”

9 April 2021 (University of Gothenburg) – For the first time, researchers have been able to obtain data from underneath Thwaites Glacier, also known as the “Doomsday Glacier”. They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow. With the […]

Sea level rise is killing trees along the Atlantic coast, creating “ghost forests” that are visible from space

By Emily Ury 6 April 2021 (The Conversation) – Trekking out to my research sites near North Carolina’s Alligator River National Wildlife Refuge, I slog through knee-deep water on a section of trail that is completely submerged. Permanent flooding has become commonplace on this low-lying peninsula, nestled behind North Carolina’s Outer Banks. The trees growing in […]

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020 – Carbon dioxide levels now higher than any time in past 3.6 million years – Largest annual methane increase ever recorded

7 April 2021 (NOAA) – Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today. The global surface average for carbon dioxide (CO2), calculated from measurements collected at NOAA’s remote sampling locations, was […]

24 September 2020 (CCAF) – The Cambridge Centre for Alternative Finance (CCAF) at the Cambridge Judge Business School today published the third edition of its Global Cryptoasset Benchmarking Studywhich highlights the industry’s efforts to address regulatory concerns over anti-money laundering (AML) and combating the financing of terrorism (CFT), but cautions that efforts to address issues such […]

Monthly evolution of global CO2 emissions in 2020, relative to 2019. After hitting a low in April 2020, global emissions rebounded strongly and rose above 2019 levels in December. Global CO2 emissions were 2 percent, or 60 million tonnes, higher in December 2020 than they were in the same month a year earlier. Major economies led the resurgence as a pick-up in economic activity pushed energy demand higher and significant policies measures to boost clean energy were lacking. Many economies are now seeing emissions climbing above pre-crisis levels. Graphic: IEA

After steep drop in early 2020, global carbon dioxide emissions have rebounded strongly – “The rebound in global carbon emissions is a stark warning that not enough is being done to accelerate clean energy transitions worldwide”

2 March 2021 (IEA) – The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data released today, but the overall decline of about 6% masks wide variations depending on the region and the time of year. After hitting a low in […]
