By Somini Sengupta, The New York Times. 

Excerpt: It’s not officially summer yet in the Northern Hemisphere. But the extremes are already here. Fires are burning across the breadth of Canada, blanketing parts of the eastern United States with choking, orange-gray smoke. Puerto Rico is under a severe heat alert as other parts of the world have been recently. Earth’s oceans have heated up at an alarming rate. ...the science is unequivocal that global warming significantly increases the chances of severe wildfires and heat waves like the ones affecting major parts of North America today. Now comes a global weather pattern known as El Niño, which can drive up temperatures and set heat records. Thursday morning, scientists announced its arrival....

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....

https://www.washingtonpost.com/climate-solutions/interactive/2023/flood-resistant-home-bamboo/ By Nick Aspinwall, The Washington Post.  Excerpt: Yasmeen Lari spent a …career designing …structures out of concrete, glass and steel before stumbling into her ideal material. It was at a camp for refugees…. Residents there were struggling to secure bricks and wood to build communal kitchens — until she spotted a nearby bamboo grove. “Let’s use it,” recalls Lari…. The material worked so well that over the last decade, Heritage Foundation of Pakistan …has built some 85,000 structures for displaced Pakistanis, including victims of last year’s devastating monsoon rains. That disaster, the worst flooding in Pakistani history, left a third of the country underwater and  destroyed more than 2.1 million homes . The thousands of bamboo structures Lari’s group had erected “all survived,” she said. …Many species of bamboo have been used as a building material in Asia for thousands of years and they are

Climate Change Drives New Cases of Malaria, Complicating Efforts to Fight the Disease

https://www.nytimes.com/2023/11/30/health/malaria-climate-change.html By  Stephanie Nolen , The New York Times.  Excerpt: There were an estimated 249 million cases of malaria around the globe last year,  the World Health Organization said on Thursday , an increase of five million over 2021. Malaria remains a top killer of children. Those new cases were concentrated in just five countries: Pakistan, Nigeria, Uganda, Ethiopia and Papua-New Guinea. Climate change was a direct contributor in three of them, said Dr. Daniel Ngamije, who directs the W.H.O. malaria program. In July 2022, massive flooding left more than a third of Pakistan underwater and displaced 33 million people. An explosion of mosquitoes soon followed. The country reported 3.1 million confirmed cases of malaria that year, compared with 275,000 the year before, with a fivefold increase in the rate of transmission....
