https://www.sciencemag.org/news/2021/07/un-climate-panel-confronts-implausibly-hot-forecasts-future-warming Source: By  Paul Voosen , Science Magazine.  Excerpt: Next month, after a yearlong delay because of the pandemic, the U.N. Intergovernmental Panel on Climate Change (IPCC) will begin to release its first major assessment of human-caused global warming since 2013. The report...will drop on a world that has starkly changed in 8 years, warming by more than 0.3°C to nearly 1.3°C above preindustrial levels. Weather has grown more severe, seas are measurably higher, and mountain glaciers and polar ice have shrunk sharply. ...But as climate scientists face this alarming reality, the climate models that help them project the future have grown a little too alarmist. Many of the world’s leading models are now projecting warming rates that most scientists, including the modelmakers themselves,  believe are implausibly fast . ...scientists have scrambled to understand what went...

Climate Litigation Has a Big Evidence Gap

https://eos.org/articles/climate-litigation-has-a-big-evidence-gap Source: By  Kimberly M. S. Cartier , Eos/AGU  Excerpt: Climate change has found its way into courtrooms around the world more and more often in recent years: Plaintiffs have brought more than 1,500 cases of climate litigation since 1986, and  an increasing number of cases  are filed each year. ... However, climate litigation has failed more often than not to hold greenhouse gas emitters accountable for  climate-related impacts  like flooding and damage from drought or wildfires. ...The researchers examined 73 cases across 14 jurisdictions worldwide that made a claim that a defendant’s emissions negatively impacted the plaintiffs. In those cases, courts did not dispute the general idea that greenhouse gases cause climate change. “What was more of a challenge,” Stuart-Smith said, “was establishing a causal relationship between greenhouse gas emissions of an individual entity…and specific impac...

How to cool your home without relying on air conditioning

https://www.washingtonpost.com/climate-solutions/2021/07/23/passive-cooling-heat-wave/ Source: By  Sarah Kaplan , The Washington Post.  Excerpt: On a warming planet, passive cooling can help protect people without access to air conditioning and lighten the load on the electrical grid from those who do. It can also help reduce greenhouse gas emissions produced by burning fossil fuels for power — a necessary step for tackling climate change and the only hope we have for avoiding an even hotter future. ...Having vegetation around your building can prevent the walls from heating up as well. ...“Cool roofs” also make a big difference, Rempel said. Topping a building with light-colored, highly reflective materials prevents it from soaking up the sun’s heat. Even better: Build a rooftop garden. ...As night falls and the outdoor air temperature drops, it’s time to open up your windows. Create cross ventilation by opening windows and doors on opposite sides of rooms. ...if indoor air t...

In America’s least air-conditioned cities, brutal heat changes some people’s minds

When highs topped 90 degrees for a few days before returning to the more ordinary 60s, she checked her grandkids and herself into a local hotel for the AC and the pool. But she will not buy her own AC unit. That’s not the kind of place where she lives. In Portland, Ore., however, the heat finally got to Vivek Shandas. He’s lived in the Pacific Northwest for 21 years and had resisted buying an air conditioner until this summer. “This thing broke us,” he said.  After highs hit 108, 112 and 116 degrees  on successive days last month, he bought a portable unit, put it in his bedroom and ...
