NOAA makes it official: 2011 among most extreme weather years in history

Just shy of the halfway mark, 2011 has seen eight $1-billion-plus disasters, with total damages from wild weather at more than $32 billion, according to the National Oceanic and Atmospheric Administration. Agency officials said that total could grow significantly, since they expect this year's North Atlantic hurricane season, which began June 1, will be an active one.
Overall, NOAA experts said extreme weather events have grown more frequent in the United States since 1980. Part of that shift is due to climate change, said Tom Karl, director of the agency's National Climatic Data Center.
"Extremes of precipitation are generally increasing because the planet is actually warming and more water is evaporating from the oceans," he said. "This extra water vapor in the atmosphere then enables rain and snow events to become more extensive and intense than they might otherwise be."
But for some kinds of extreme weather, teasing out a contribution from climate change is more difficult.
The second half of April brought a swarm of tornadoes that leveled parts of the Midwest, including the twister that killed 151 people in Joplin, Mo. So far, 2011 has seen the sixth-highest number of tornado deaths on record, prompting many people to wonder whether climate change has played a role. So far, scientists say there's no good evidence for or against a climate change influence on tornado behavior.
Meanwhile, computer models predict that droughts -- like those that have scorched large swaths of Texas, New Mexico and Arizona this year -- will become stronger and more frequent as climate change continues. But because patterns of drought vary widely from decade to decade, that makes it "very difficult and unlikely that we're going to be able to discern a human fingerprint, if there is one, on the drought record in the foreseeable future," Karl said.

Climatologists have been warning that increasing atmospheric carbon will lead to more severe storms, tornadoes and hurricanes for the past 30 years.

Well, just ask JanforGore, she can find a human fingerprint on any weather event - especially droughts!!!

I read a comment a while back from a climate change "opponent". Stating one recent event had occurred 300 years ago, and another 100 years ago. The statement implied "what's the problem". (LMAO) The events had happened over a 200 year span. Not 1 year. The commenter had undone their own position without seeing it. Significant events happening 200 times faster doesn't allow much time for recovery and that is one major problem! Natural laws cannot be ignored without getting burned.

Yes, that's a common tactic. Total ignorance and spin. And you are correct that this is a major problem. The changes are occurring faster than we can adapt to them as we continue to add to them which just increases the effects in a viscious cycle. I don't see what is so hard to understand about that.

I've been watching the increasingly worstening fires, droughts, floods and storms since I first became aware of global warming back in the mid-1980s.
EVERYTHING climatologists warned would happen IS HAPPENING and far faster than ANYONE predicted because of positive climate feedbacks from melting tundra and bigger fires.
The deniers have changed their position many times since the 80s. First they said it was a liberal conspiracy out to destroy capitalism. Then in the 90s when global warming began to become undeniable they said it was a good thing and that crops would grow faster. Next they said it was thousands of leading scientists from every nation fudging data. Finally they are saying that it is arrogant to propose that humans can change climate by reducing carbon dioxide emissions even though we have already changed the climate with our Co2 emissions.
Meanwhile we are rapidly passing the climate tipping point and still nothing of significance is being done to stop it -- all because of these deniers who are partisan liars.
How much worse does it have to get before we take action? - 11 months ago

Why wait. We should be setting aside egos and be personally responsible for our individual carbon foot prints within our individual means. We should already be doing this.
The remark "that it is arrogant to propose that humans can change climate" stems from arrogance and ignorance, and it is up to us to prove them wrong. Change is occuring in attitudes slowly, but quicker than the environment can snap back. No quick fix is available, and being impatient can drive you nuts. Press on. - 11 months ago

200 times faster? So you really fall for sensationalistic journalistic expressions?
With increasing populations and civilisations covering a wider area, weather events are more noticed and reported more often. Of course the monetary value of natural disasters is going to rise, what else would you expect?
Similar, and worse events have happened previous to this year, only then extreme weather was seen for exactly what it was - extreme weather. - 11 months ago

Ah yes, it's a continuous downward spiral into calamity now, isn't it? All these feedbacks and the flooding of the atmosphere with that nasty chemical CO2... we might as well give up now, we're doomed!!! Everything is spiralling into disaster faster than ever, quicker than predicted, worse than dreamt of... how will we ever survive?
Do you ever look out your window? Been to many places, have you? Seen a bit of the world?

Actually the more I read your comments the more I'm learning:
Everything that happened before the industrial revolution was good, normal, nice and stable.
After the industrial revolution, everything is man's fault, disastrous and a one-way slide into mayhem. - 11 months ago

I have lived in Pennsylvania, North Carolina, Colorado, California and Hawaii for many years and from what I've observed droughts and fires and floods and severe storms ARE getting a lot worse all around the world.

Actually, I must apologise, if you say droughts, fires, floods and severe storms are getting worse then who am I to say otherwise? I mean, what with all the training you've had, and your experience of world travel, you're really at the cutting edge of climatology. - 11 months ago

Hey we better cut the budget for NOAA. Can't have them coming up with data that supports climate change and global warming. If they were producing data that supported, climate change deniers, global warming skeptics, and Flat Earthers in general, they would be awash in funds.

Get used to the new normal. I guess after hiding our heads in a hole for so many years, now we will probably have to living in one.
In other-words going underground to get out of the weather.

Even government agencies have to play both sides to not inflame the ire of fossil fuel companies. It is, but we aren't sure it is. Great answer in an election year. We know the truth.
