Chris Mooney | Forget Tornadoes. Lets Talk--Unendingly--About Heat Waves and Global WarmingHowever, we’ve just experienced a staggering U.S. heat wave (visual here), and that makes it seriously time to talk about the link to climate change, and not shut up any time soon.
...
What this means is that now—not during the May peak of tornado season—is the time to once again try to rally the public to care about climate change.
...
That's why summer is always the wtime to talk to the public about global warming, and we need to recognize that other parts of the year probably aren't as good.
And lest you think this too obvious to bear mentioning, never forget: In 2009, the IPCC held an absolutely critical meeting in a snowy December in Copenhagen.
[December 2010: Chris Mooney | Warming and Winter StormingThis common insinuation--that somehow, human-caused climate change is refuted by the perennial occurrence of bad winter weather--puts us scientific rationalists in a bind. The problem is that unlike many denier talking points, there isn’t really even an argument being put forward here that might be refuted. It’s more of a “nyah nyah,” followed by, “I never believed you to begin with, but this time of year, I just feel sorry for you.”
I mean, sure, we can reply by pointing out the distinction between climate and weather. We can further explain why global warming can actually mean more snow because warmer air holds more moisture--something a few brave souls attempt to get across each winter.

After Story on Monster Heat Wave, NBC Asks “What Explains This?” The Answer: “We’re Stuck in a Summer Pattern”! | ThinkProgressAhh, but when it comes to actually connecting the dots between extreme weather we’re now experiencing and global warming, well, that story is apparently too hot to handle — even when the data does support that view.
The southwest is in an uber-hot drought, but the NY Times says no dots to connect to global warming
[Is Romm too stupid to understand the difference between weather and climate?] Best Heat Wave Cartoons, Toles Gets “Hot and Bothered” | ThinkProgress“Experts: Cold snap doesn’t disprove global warming” | Romm, January 2010 - ThinkProgressIt bears repeating, as I said on Fox, that global warming can’t turn January into July. So merely reporting it’s cold in January isn’t news that has any relevancy to global warming.
...to say, it was so cold yesterday in one city it didn’t even break the record or we just had a once-in-30-years weather event, well, that’s just not evidence of anything but boredom by the media.
...
We’ve only had about 1°F warming in recent decades, which can’t do much more than skew the odds — it certainly hasn’t warmed anywhere near enough to have driven us outside the bounds of the much larger temperature swings that come from regional weather patterns, let alone the seasons.
...
And for some reason, it always bears repeating that precipitation isn’t temperature
Living With the Greenhouse Effect - NYTimes.comSo much for warmups. The summer of 2011 is indicative of the new climatological norms that are emerging as conditions neatly echo longstanding projections of the consequences of steadily raising the concentration of heat-trapping greenhouse gases.
[Revkin, March 2008] Skeptics on Human Climate Impact Seize on Cold Spell - New York TimesThe world has seen some extraordinary winter conditions in both hemispheres over the past year: snow in Johannesburg last June and in Baghdad in January, Arctic sea ice returning with a vengeance after a record retreat last summer, paralyzing blizzards in China, and a sharp drop in the globe’s average temperature.
It is no wonder that some scientists, opinion writers, political operatives and other people who challenge warnings about dangerous human-caused global warming have jumped on this as a teachable moment.
...
According to a host of climate experts, including some who question the extent and risks of global warming, it is mostly good old-fashioned weather, along with a cold kick from the tropical Pacific Ocean, which is in its La Niña phase for a few more months, a year after it was in the opposite warm El Niño pattern.
...
Many scientists also say that the cool spell in no way undermines the enormous body of evidence pointing to a warming world with disrupted weather patterns, less ice and rising seas should heat-trapping greenhouse gases from burning fossil fuels and forests continue to accumulate in the air.
In Case You Haven't Noticed, It's Hot | Mother JonesJulia Whitty had a scary post earlier this week about the new climate normal. Basically, we should all get used to the fact that the horrendous heat wave across the Midwest, South, and Mid-Atlantic region is going to be business as usual from here on out.
February 2010: Climate Bill Snowed Under? | Mother JonesThe blizzard on the East Coast has dumped several feet of silliness on D.C., as Republicans rush to exploit the record snowfall as evidence that global warming doesn't exist.
...
So perhaps it's time for a refresher. "Weather" and "climate" are not the same thing. Weather is what happened yesterday or may happen tomorrow; climate patterns occur over decades.
It's Hot! But Fox Only Talks About Global Warming When It's Snowing | Media Matters for America NASA climatologist Gavin Schmidt told Media Matters it's "very probable that any particular heat wave happening now will be shown to have become more likely because of global warming," adding: "Of all the different extreme events that can happen, the partial attribution of heat waves to ongoing climate change is one of the easier connections."
Schmidt explained that there are a number of questions to ask when considering whether global warming may be contributing to extreme weather events...
2010: Scientist Discusses Latest Report of Rising Global TemperaturesNASA: Many have noted that the winter has been particularly cold and snowy in some parts of the United States and elsewhere. Does this mean that climate change isn’t happening?
Gavin Schmidt: No, it doesn’t, though you can’t dismiss people’s concerns and questions about the fact that local temperatures have been cool. Just remember that there’s always going to be variability. That’s weather. As a result, some areas will still have occasionally cool temperatures — even record-breaking cool — as average temperatures are expected to continue to rise globally.
NASA: So what’s happening in the United States may be quite different than what’s happening in other areas of the world?
Gavin Schmidt: Yes, especially for short time periods. Keep in mind that that the contiguous United States represents just 1.5 percent of Earth’s surface.
