Daily Climate Change: Global Map of Unusual Temperatures, Mar 8, 2015

How unusual has the weather been? No one event is “caused” by climate change, but global warming, which is predicted to increase unusual, extreme weather, is having a daily effect on weather, worldwide.

Looking above at recent temperature anomalies, much of the US and the waters surrounding it are experiencing warmer than normal temperatures: the eastern Pacific warm spot continues to prevent much rain from reaching California, sending it into further drought.

Much of the areas surrounding the North Pole are experiencing much warmer than normal temperatures – not good news for our Arctic thermal shield of ice. Hotter than usual temperatures continue to dominate human habitats.

Natural Repercussions:

OO A February First: Planetary CO2 Levels Pass 400 PPM Milestone – while many experts have said that 350 ppm and above allows the development of dangerous climate change.

A Historical First: 2 Consecutive Record -Warm Winters in California are caused by a stable high pressure ridge just off the California coast reports Andrea Thompson at Climate Central. The ridge, in turn, is likely fueled by the extremely warm Pacific waters beneath it, says a NOAA climatologist.

Since ocean temperatures change very slowly, though, don’t expect the ridge – or hot dry weather – to end anytime soon. Meanwhile, the state’s water storage system, the snowpack, is at near-record low levels. The drought continues…

OO Global Warming Will See Australian Deserts Grow Bigger – says a new US study; not good, given how much desert already exists there.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here. This is an ongoing campaign (the next Congressional election is in 2016!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
