Climate Central has made it official. 2012 will be (almost positively certainly) the warmest year in the U.S. over the past 118 years of climate records. To put it more simply, the warmest year on record. Check it out:
We know that there is no debate in the scientific community about the existence and cause of global warming. We also know that it will likely be the defining issue in the next 50 years and beyond, and young people must join forces to fight for their future.
So if you’re young, if you’re old, if you want to do something … I dedicate this song to you. Children of all ages, “the world is burning down, and you’re the ones to lead.”
Find out when your house will be overtaken by rising seas! There’s an interactive app for that.
Some quotes about climate change from a growing collection I keep.
If we don’t listen to the scientists, at least we can listen to the animals?!?
“Why Climate Deniers Have No Scientific Credibility - In One Number”
Deniers of climate science are fond of the following wacky idea: That the scientific community does not agree on the cause of climate change. It’s time to bury that idea like a senile dog hiding a ham bone: Somewhere where we’ll forget about it forever.
According to some recent data-mining of the scientific literature, 0.17% is the percentage of peer-reviewed scientific papers in the past 21 years that offer a scientifically-viable alternative to human-caused global warming.
Only 24 of 13,950 articles (0.17%) try to make this case in a scientific manner. If any of them were right, they would have been cited hundreds of times, instead of forgotten forever.
Among the public, denying global warming is a very popular and very influential idea. Among scientists, it holds slightly less than no water.
With the average temperature on Earth in October becoming the 332nd consecutive month at a higher-than-normal mark, we’re defining the new normal for a whole generation.
And that’s not a “new normal” that we should be okay with. Because a warming Earth with frequent droughts and supercharged storms could make Hurricane Sandy look like an afternoon sprinkle.
This NASA animation of temperature data from 1880-2011 shows the shift upward in normal global temperatures. The more red you see, the higher the deviation from the historical average.
So much red.
Show this to anyone left that argues that this isn’t actually happening, which would be pretty hard to believe, actually. I think the real question some people have a problem with today is “Why?”
Well, science points to the cause being us. Here’s a great feature from New Scientist to answer some of your curious or skeptical questions, and to help you learn more about the causes of climate change.
The New Normal - Shifting Extreme Temperatures
One of the clearest signs that global warming is accelerating has been the extreme temperatures we see during summer. Since the 1950’s these temperatures have not only gotten more extreme (hotter), but they are also happening more often.
Using animated data from NASA climate studies, I put together this GIF so you can see how extreme temperatures are getting more frequent:
As the curve shifts to the right, you can see that it stays about the same height, but the number of days that are extremely hot (farther to the right) takes over.
And there’s no sign of this changing any time soon.
The next summer blockbuster? CLIMATE CHANGE, 3-D!!
… these guys are good. You’d almost swear this is what global warming looks like, since it’s exactly what scientists have been predicting for decades. Indeed, the head of the nation’s climate data center, in Asheville, N.C., used the kind of scary language we’ve come to expect from climate alarmists, calling the record–breaking week “a super-heated spike on top of a decades-long warming trend.”
That’s why it would be so scary if it wasn’t a hoax. But it must be, because if it was a real crisis, responsible authorities would be taking action. The president wouldn’t be approving new oil drilling in the Arctic on the very same week. The Interior Secretary wouldn’t be auctioning off a vast new store of coal. The Republican presidential nominee wouldn’t be promising to approve the Keystone pipeline to the vast tarsands of Canada as his very first order of business.
Funny, but in that really, really sad way.
The map above shows predicted ecosystem shifts (like a complete change of type, forest -> grassland) for the year 2100 based on current climate change models.
By 2100, global climate change will modify plant communities covering almost half of Earth’s land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another …
