“It’s not just going to be heatwaves, drought, wildfires and hurricanes. It’s going to be water resources, it’s going to be food supplies ... it’s going to be national security concerns that are going to be more apparent than they are right now,” said Brown University climate scientist Kim Cobb.Those living in the least developed nations or in poorer communities

. Many have called for rich, high-polluting countries, like the U.S. and much of Europe, toto weather extremes and can curb their use of fossil fuels. Known as “loss and damage” in climate negotiations, it’s an area that nations have struggled to agree on in recent years.In a somewhat rare moment of agreement between rich nations and more climate-vulnerable, low-emitting ones, countries at the U.N.'s annual climate conference in Paris in 2015 did agree to limit warming to “well below” 2 degrees Celsius (3.6 Fahrenheit) since pre-industrial times, with the aim of capping

Alternatives to fossil fuels, like solar and wind energy, need to be scaled up dramatically if the Paris climate goals are to be met, experts say. Newer technologies, like carbon capture or green hydrogen, which are currently too expensive, untested at scale or both, will also have to be deployed to limit warming. Changes in people’s personal lives can also make a difference, although the large reductions come from government policies and choices made by giant corporations, rather than individuals.Although some effects of global warming are locked in, many scientists believe that curbing warming to just a few more tenths of a degree is achievable, but only if drastic action is taken very quickly.

He wanted to finish in under an hour and felt fine until a big hill late in the race made him light-headed. By then he could see the finish line and his competitive nature kicked in.

Soon after finishing, he lost consciousness. His temperature was the highest Jardine has seen at Falmouth – 112.8 degrees (44.9 Celsius).“That’s crazy,” said Dr. Sameed Khatana, a professor of medicine at the University of Pennsylvania. “That is not compatible with life.”

But Hauptmann got immediate care, with a half-hour in the ice bath bringing his temperature down quickly, and he went home that day. Doctors worried about organ damage. Blood tests showed high protein levels from muscle breakdown, but they came down and he avoided lasting injury.Two weeks later he started playing football again. But he’s more aware of heat’s danger, and makes sure to stay hydrated and aware of how he is feeling.
