The baking Pacific Ocean is changing the weather on the Southern California coast

sudshr47 August 15, 2018

Ocean temperatures off the Southern California coast have been profoundly warm in August, with a number of all-time high temperatures recorded in San Diego’s almost bath-like waters.

These extreme marine temperatures — created by weather patterns and boosted by climate change — have a sphere of influence beyond the oceans, as this heat has contributed to unusual heat and mugginess on the heavily-populated coast.

This is not the norm for seaside San Diego, which is famous for its sunny, though moderate, climate.

“We’re in a record-setting streak right now,” Mark Moede, a National Weather Service meteorologist in San Diego, said in an interview. “It’s unprecedented — typically it’s pretty temperate.” Read more…

Climate Change Europe Global Warming Heat Waves Science

It’s 90 degrees in the Arctic Circle this week. Here’s why.

The Arctic Circle — the realm of polar bears and dwindling sea ice at the top of the world — hit 90 degrees Fahrenheit, 32 degrees Celsius, this week.

This was the temperature in Banak, Norway on July 30, though some Norwegian areas even reached a couple degrees warmer, according to the European meteorology site severe-weather.eu. Banak sits atop northern Europe, over 350 miles above the bottom edge of the Arctic Circle.

The greater Northern Hemisphere and Europe itself have been repeatedly scorched by both record and near-record temperatures this summer, a consequence of overall rising global temperatures. Read more…

Extreme Arctic heat wave in 2016 wouldn’t have happened without climate change

sudshr47 May 8, 2018

Just days before Christmas in 2016, the North Pole was 50 degrees above its usual winter temperature. The top of the world was just above freezing.

Unusually warm air had smothered the Arctic throughout that year, and now a recently published report, led by government scientists at the National Oceanic and Atmospheric Administration (NOAA), found that it’s nearly impossible to explain the intensity of this warmth simply by normal fluctuations in weather.

A heating event like this isn’t natural, they argue — it’s largely human-induced, specifically by the greenhouse gases emitted by human industry and trapped in the atmosphere. Read more…
