Excerpt: ...Soaring temperatures can damage not just the body but also the mind. As heat waves become more intense, more frequent and longer, it has become increasingly important to address the impact on mental health, scientists say. “It’s really only been over the past five years that there’s been a real recognition of the impact,” said Dr. Joshua Wortzel, chair of the American Psychiatric Association’s committee on climate change and mental health, which was set up just two years ago. ...High temperatures are strongly associated with an increase in suicides, researchers have found. Heat has been linked to a rise in violent crime and aggression, emergency room visits and hospitalizations for mental disorders, and deaths — especially among people with schizophrenia, dementia, psychosis and substance use. For every 1 degree Celsius (or 1.8 degrees Fahrenheit) increase in temperature, scientists have estimated that there is a nearly 5 percent increase in the risk of death among patients with psychosis, dementia or substance use. Researchers have reported a 0.7 percent increase in suicides linked to rising temperatures, and about a 4 percent to 6 percent increase in interpersonal violence, including homicides. Heat not only fuels feelings like irritability and anger, but also seems to exacerbate mental illnesses, such as anxiety, schizophrenia and depression. Older adults, adolescents and people with pre-existing mental illnesses are particularly vulnerable, as are people who do not have housing or are of lower socioeconomic status....

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....

An architect has found a way to build flood-proof homes

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....
