La Nina likely to develop in the Pacific by December

Phoenix Will Be Almost Unlivable by 2050 Thanks to Climate Change

Sorry to put such a fine point on this, but even without climate change, Phoenix, Arizona, is already pretty uninhabitable. Don’t get me wrong, I spend a fair amount of time there, and I love it—particularly in the fall and winter—but without air-conditioning and refrigeration, it would be unlivable as is. Even with those modern conveniences, the hottest months take their toll on my feeble Southern Californian body and brain. The historical average number of days per year in Phoenix that hit 100 degrees is a mind-bending 92. But that number is rapidly rising as climate change bears down on America’s fifth-largest city.

 

“It’s currently the fastest warming big city in the US,” meteorologist and former Arizonan Eric Holthaus told me in an email. A study from Climate Central last year projects that Phoenix’s summer weather will be on average three to five degrees hotter by 2050. Meanwhile, that average number of 100-degree days will have skyrocketed by almost 40, to 132, according to another 2016 Climate Central study. (For reference, over a comparable period, New York City is expected to go from two to 15 100-degree days.)

And, tragically, all that heat costs quite a few Phoenicians their lives every year. Maricopa County keeps careful records of heat deaths and issues a morbid but extremely useful annual report. In 2016, 130 people died from heat—the…

 

La Nina likely to develop in the Pacific by December, Bureau of Meteorology says

La nina 17

A La Nina is almost certain to develop in the Pacific this summer, as all eight models used by the Bureau of Meteorology anticipate threshold levels for the key climate pattern will be reached or exceeded by next month.

The bureau’s latest fortnightly assessment of conditions in the Pacific and Indian oceans rates the likelihood of a La Nina this summer at about 70 per cent – triple the usual level – prompting it to issue a La Nina alert on Tuesday…
