(TM David Zetland)

The late Pete Seeger sang about water, especially the Hudson River he fought for.

Have trouble understanding California’s water system? Even if you’ve lived in the state all your life? One of the foremost experts on the subject, Jay Lund, explains it all for you in one map.

Whether or not this is evidence of climate change, the long-term warming trend was sustained in 2013. Read more in NCDC’s Global Climate Report.

Climate scientists are 95 percent certain global warming is happening and human actions are largely the cause. AP science writer Seth Borenstein explains what 95% certainty of warming means to scientists.

President Obama said it Tuesday night:

But the debate is settled. Climate change is a fact. And when our children’s children look us in the eye and ask if we did all we could to leave them a safer, more stable world, with new sources of energy, I want us to be able to say yes, we did.

You might be inclined to argue, but these three arguments have been discredited:

“The warming is just part of a natural cycle.”

“We’ve been warming up since the last ice age.”

“To think humanity can influence the climate is pure arrogance.”

The Los Angeles Times’ letters page editor has no time for climate change denial:

Saying “there’s no sign humans have caused climate change” is not stating an opinion, it’s asserting a factual inaccuracy.

Such errors of fact won’t make it on the LAT’s letters page.

Lest you think that global warming was happening, but has leveled off since 1998: no, it hasn’t and here’s why.

One group that has a monetary stake in the matter is the reinsurance industry. If they bet that the climate will go on as usual and that there will be no more than the usual number of extreme events — and that turns out to be wrong — it could cost them tens of billions of dollars per year. There are no climate change deniers to be found in the reinsurance business.

Finally, if the West Virginia chemical spill were terrorism

Military

The branches of the U.S. military are very concerned about climate change, both because they believe it will increase competition for resources in less-stable parts of the world and because it will change the nature of the Arctic.

Good and bad ways of dealing with climate change

A group of scientists suggest that concentrating on reducing pollutants like soot, ozone, and methane would mitigate climate change, would show more immediate benefits, and might be more politically feasible than concentrating on carbon dioxide (CO2).

Climate change is threatening the American way of life

Scientists are predicting serious consequences from climate change. There’s a good chance that it will lead to water shortages and an increase in violence and civil war, for example. And yet large numbers of Americans aren’t too worried about climate change, especially if they belong to the Republican or Tea parties.

Two recent news items may change their minds. Climate change could do real damage to the American Way of Life.

Baseball could become a more violent sport as pitchers are more likely to retaliate against batters in warmer weather.

Chocolate production could be crippled in the West African nations that produce most of it.

There you have it. If those two items don’t concern every red-blooded American, I don’t know what will.

Climate change may be cooling California

From the Sacramento Bee:

Spring passed California by, and summer remains in hiding.

Nine tornadoes have torn up the Sacramento Valley from Oroville to Fairfield. A giant Sierra snowpack, still frozen fast, has put innumerable summer adventures on hold.

The Golden State’s weather has gone haywire.

And it’s not over yet: Sacramento can expect as much as another 1.4 inches of rain this weekend and temperatures 20 degrees below normal, with more mountain snow.

“It’s what I call global weirding,” said Bill Patzert, a climatologist at NASA’s Jet Propulsion Laboratory in Pasadena. “This has been a very strange year all over the planet.”
