By International Energy Agency (IEA). 

Excerpt: First-of-its-kind global study finds the world must add or replace 80 million km of grids by 2040, equal to all grids globally today, to meet national climate targets and support energy security. ...Achieving all national climate and energy goals will require adding or replacing 80 million kilometres of power lines by 2040 – an amount equal to the entire existing global grid – according to a detailed country-by-country analysis carried out for the report. Major changes to how grids operate and are regulated are also essential, while annual investment in grids, which has remained broadly stagnant, needs to double to more than USD 600 billion a year by 2030....

Like McCann, the three others had turned up feverish and confused. ...among the possible causes were mosquito-borne viruses, in particular two encephalitis-causing viruses endemic to Australia: Kunjin, a strain of West Nile virus, and Murray Valley encephalitis virus (MVEV), named for the river valley where McCann has swum, water skied, fished, and boated since he was a boy. ...As with other weather events, the record-breaking wetness of the 2021–22 season can’t be attributed with certainty to climate change. But as the globe warms, the atmosphere holds more water, enabling more intense rainfall and flooding; daily rainfall associated with th

Relax, Electric Vehicles Really Are the Best Choice for the Climate

https://www.nytimes.com/2023/11/24/opinion/electric-vehicle-tesla-hybrid.html By Stephen Porder , The New York Times, opinion piece.  Excerpt: ...I am familiar with trepidation about electric vehicles; ...worry about running out of battery power far from a charging station; ...the upfront costs... though the E.V.  has a lower total cost  over the life of the car. ...Those concerns will likely diminish in 2024 as money from the Inflation Reduction Act flows into building more charging stations and making discounts for electric vehicles available right at the dealership. ...while there are environmental concerns with [electric vehicles], they are dwarfed by the benefit they provide regarding climate change. ...Cobalt, another key component of batteries, has been in the public eye because of its scarcity and the  horrific working conditions for miners  in the Democratic Republic of Congo. Those conditions need to be addressed, but it’s a mistake to view them in isolation. Oil extraction h

Lost history of Antarctica revealed in octopus DNA

https://www.science.org/content/article/lost-history-antarctica-revealed-octopus-dna By ERIK STOKSTAD .  Excerpt: Some 100,000 years ago, scientists believe Antarctica’s massive western ice sheet collapsed, temporarily opening waterways between a trio of seas surrounding the continent. New evidence for that scenario comes from a surprising source: octopus DNA. ...About 129,000 to 116,000 years ago, a warm spell called the last interglacial gave our planet a brief break in between several million years of ice ages. The average temperature of the planet was about 0.5°C warmer than it is today—and climate projections predict it will be again within decades. The global sea level was also 5 meters to 10 meters higher than current levels. Many scientists believe  the collapse of the West Antarctic Ice Sheet and consequent melting could have been a primary reason . ...The findings are consistent with growing geological evidence supporting the ice sheet collapse....
