The sustained transformation to a warmer, less frozen and biologically changed Arctic remains clear Extreme warm air temperatures in the Eurasian Arctic illustrate significant region-wide effects of year-to-year variability and connections across the Arctic environment.
Highlights
·The average annual land surface air temperature north of 60° N for October 2019-September 2020 was the second-highest on record since at least 1900. Record warm temperatures in the Eurasian Arctic were associated with extreme conditions in the ocean and on the land.
In the oceans
· Sea ice loss in spring 2020 was particularly early in the East Siberian Sea and Laptev Sea regions, setting new record lows in the Laptev Sea for June. The end of summer sea ice extent in 2020 was the second-lowest in the 42-year satellite record, with 2012 being the record minimum year.
· August mean sea surface temperatures in 2020 were ~1-3°C warmer than the 19822010 August mean over most of the Arctic Ocean, with exceptionally warm temperatures in the Laptev and Kara seas that coincided with the early loss of sea ice in this region.

Building world's 1st pyramid
In a preprint study published this summer, researchers proposed that ancient Egyptians built the world's first pyramid the 4,700-year-old Step Pyramid of Djoser, which sits on Egypt's Saqqara plateau using a \"modern hydraulic system\" powered by a long-gone branch of the Nile River.

Understanding Monkeypox: Insights and Implications
Monkeypox, a viral zoonotic disease, has gained significant attention in recent years due to its re-emergence and sporadic outbreaks globally.
AI predicts that most of the world will see temperatures rise to 3°C much faster than previously expected
Three leading climate scientists have combined insights from 10 global climate models and, with the help of artificial intelligence (AI), conclude that regional warming thresholds are likely to be reached faster than previously estimated.
Infrared Radiation: A New Player In Mosquito Host-Seeking

A new class of antivirals could help prevent future pandemics
The arrival of Paxlovid in December 2021 marked another turning point in the COVID-19 pandemic an effective antiviral that has since successfully treated millions.
Turning carbon emissions into methane fuel
Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources. Carbon dioxide (CO2) is a greenhouse gas that accounts for a large part of Earth's warming climate, and is produced by power plants, factories and various forms of transportation.
