Scientists analyze recent extreme weather events in relation to climate change _ pbs newshour

HARI SREENIVASAN: Two major disasters in two different parts of the country have sent tens of thousands of people fleeing from their homes, and caused millions of dollars in damage. Ag gaston birmingham Are these just freak events, or are they in some way related to climate change?

WILLIAM BRANGHAM: It’s called the Blue Cut Fire, and it’s wreaking havoc in Southern California. Gas station jokes The massive blaze closed major roadways like part of Interstate-15 that connects Los Angeles and Las Vegas. Gaz 67b tamiya 1 35 And last night, officials issued evacuation orders for more than 34,000 homes. Electricity review worksheet answers That’s some 82,000 people.

WILLIAM BRANGHAM: The fire erupted yesterday in the Cajon Pass, a critical corridor just north of San Bernardino, only 60 miles from Los Angeles.

It quickly expanded to more than 45 square miles. Gas key bolt carrier Ten air tankers, 15 helicopters and some 1,300 firefighters were deployed within 24 hours. Gas 91 octane They faced hot and windy conditions.

MICHAEL WAKOSKI, Southern California Incident Management Team: The fuels are extremely dry and very explosive this time of year. Gas vs electric stove safety And in my 40 years of fighting fire, I have never seen fire behavior so extreme as it was yesterday.

MARK HARTWIG, Chief, San Bernardino County Fire and Rescue: I was able to get up this morning and get some eyes on it from the air. Tgas advisors In a word, it was devastating, a lot of homes lost yesterday. Eon replacement gas card There’ll be a lot of families that come home to nothing.

WILLIAM BRANGHAM: Governor Jerry Brown declared a state of emergency for the Blue Cut area, as he did earlier this week for a major blaze north of San Francisco. Gas leak in car That fire has since started to fade. Gas and bloating pain The man suspected of sparking it, as well as 16 smaller fires over the last year, has now been charged with arson.

Seventeen hundred miles across the country, a different kind of disaster is unfolding in Louisiana, where some of the worst floods in history have hit the state. Find a gas station close to me As the water begins to recede in some parts, the numbers are stark. 10 gases and their uses At least 11 people have died, 30,000 people have been rescued, and 40,000 homes damaged.

WILLIAM BRANGHAM: So far, about 68,000 people have signed up for assistance from the Federal Emergency Management Agency. Gas in back symptoms The American Red Cross says this flooding has triggered its largest disaster operation since Superstorm Sandy in 2012.

The catastrophes in California and Louisiana have again raised the question: Are these events caused in part by global climate change? Both events follow a July that was the planet’s single hottest month since records began in the 19th century, and many computer models have indicated that, as temperatures rise, droughts and extreme weather are likely to follow.

To help us sort out what’s driving these extreme events, we turn to two scientists well-versed in these matters. Physics c electricity and magnetism Barry Keim is a climatologist for the state of Louisiana and a professor at Louisiana State University, and Adam Sobel is a professor of environmental science at Columbia University. 76 gas credit card account login He also directs its Initiative on Extreme Weather and Climate.

Things are slowly starting to settle down or simmer down a little bit. Electricity electricity music notes But, right now, across most of my immediate region, people have already started ripping out carpets and gutting houses. Gas calculator So, we’re already starting the cleanup.

WILLIAM BRANGHAM: So, this was obviously a historic amount of rainfall that fell on your state and that flooded you all out. Youtube gas pedal lyrics Can you give us a sense of the context of how serious these storms were, and should we be thinking about these in terms of climate change?

BARRY KEIM: This event was — it was a tropical disturbance. Hp gas online refill booking status It was a very weak — in fact, it — I would classify it practically as an easterly wave.

And the amount of rainfall amounts, as I suggested, were staggering. Electricity 4th grade worksheet Just to put this in perspective, a 100-year rain event in this region is roughly 14 inches. Gas 4 weeks pregnant A 1,000-year event is about 21 inches.

Well, we have about eight sites, seven or eight sites across southeast Louisiana or south central Louisiana that exceeded the 1,000-year mark. Gas 87 89 91 And, in fact, we have one site that had 30 — over 31 inches of rain.

Now, 1,000-year event is 21 inches, and this was 31 inches. Gasset y ortega filosofia So, that ought to give you some context on just how severe this rainstorm was across this area.

WILLIAM BRANGHAM: In that context, do you think of this as something that is — what we would expect to see with climate change, or is that not part of your thinking?

And, admittedly, this past year has been very strange. Gas bubble retinal detachment We had the floods in South Carolina. H gas l gas unterschied Texas had some serious floods. Electricity deregulation We even had a major flood earlier this year in Louisiana. Electricity sources uk In fact, we even had an early one back in this past October which was quite extraordinary.

So, it does seem like there is something unusual going on. Electricity cost per watt But I still wouldn’t quite characterize this as being a sign that the climate has officially changed. Gas density at stp We are just in a very unusual period right now. Electricity quiz ks2 And this could be indicative of climate change, but it’s way, way too early. Electricity questions grade 9 And we need a lot more data and understanding of the science to be able to say something conclusively like that.

In California, we have seen this historic drought. 4 gas planets It has dried out the landscape. Arkla gas phone number It is partly why we have seen these explosive fires across the state there. Electricity deregulation in california But, again droughts are not unusual for California, the same way floods are not unusual for Louisiana. Gas x and pregnancy How do you see these in relation to climate change?

So let’s start with the Louisiana event. 8 gases I think the California situation is a little bit different and has been going on for a number of years. Electricity font generator So, there have actually been a few studies specifically on that event.

But since we’re talking about Louisiana and the floods now, just for some general context, I mean, across the United States, as well as most places in the world where there is adequate data to ask the question, we have seen increases over the last decades, or in some cases the last century, in the extremity of severe rain events.

So, we see heavy rain events becoming heavier and a larger fraction of the rain falling at heavy events. Hair electricity song And this is what our climate projections tell us should happen as the climate warms, although to uncertain degrees, but it’s qualitatively consistent. Z gas el salvador numero de telefono And we expect it on physical grounds, as a warming climate means that there is more water vapor in the atmosphere.

Now, it’s true that each individual event is a result of many factors, and climate change is at most one of them, and usually a small one. Electricity was invented in what year So a lot of things have to happen for an extreme event to occur. Electricity icon Otherwise, it wouldn’t be an extreme event. Electricity 2pm live And so climate change can at most push the odds a little bit in one direction.

So, I mean, we now have a new emerging area of science called extreme event attribution, where people actually do studies and have ways of making probabilistic statements. Gas utility boston You can’t ever say this event was caused by climate change or this single event is conclusive evidence of climate change.

But you can say that climate change appears to have made it such a percent more probable, or given that it occurred, make it such and such percent more extreme.

Those studies haven’t yet been done on the Louisiana event. Gas density conversion My guess is that they will be done pretty soon. Gas and supply locations They can get done pretty quickly now. Gas exchange in the lungs is facilitated by And I would cautiously predict that they are going to show some increase in the likelihood of this happening due to climate change, although I wouldn’t want to put a number on it.

So, that is the sort of broad context. Gas weed I think it is the kind of thing we expect to see more as the future proceeds. Gas and electric nyc And it’s the kind of thing we have been seeing. Gas finder app But I agree that to make stronger statements than that about a specific event, it is certainly possible to overstate the connection. Electricity vs magnetism But there is a lot of science behind the statement that there may be some connection there.

I’m just curious, do you think that this is what we have just got to become accustomed to, that what was once considered an extreme event is now just the new normal? And, if so, what does that mean for policy-makers?

And — but we have had some periods in the past where we have had clustering of really big, catastrophic rainfall events in the past as well. Gas guzzler tax But I tell you, the last decade or so really does raise some eyebrows, and very, very suspicious.

And as what this means for policy implications, I mean, this is just so complex, so politically loaded, that, I mean, it’s really tough to navigate through these waters, so to speak. Electricity in homes And so, yes, it is really hard to say a whole lot conclusively on what kind of policy should proceed as a result of these recent extremes.

WILLIAM BRANGHAM: Adam, with relation to the fire in California and the many people appointed to the very long drought that has dried out much of California and makes these fires more common and more violent when they actually occur, how do you see climate change in relation to that particular event?

So, if we look at the drought in California, there have actually been several studies of it, some of it done by my colleagues here at Columbia. Electricity games online free And those studies actually show the complexity of studying events like this, because the answer actually depends how you ask the question.

If you ask about just the lack of rainfall — of course, the cause of a drought is just lack of rainfall — then the studies have tended to come to a conclusion that it’s not — this event is not fundamentally caused by climate change.

That said, once you have a lack of rainfall, the hotter temperatures that we see as a result of human influence on climate cause water to evaporate from the soils more quickly, and so you have overall a dryer land surface and lower reservoirs and all of that.

And that, there, there is a climate change influence. Electricity water analogy So if you ask about the lack of rainfall, this event appears to be largely natural, is what the studies have shown. Electricity 101 But if you ask about the overall dryness of California, there does seem to be some influence of higher temperature, which is a result of climate change.

So, the studies have come to different conclusions, in part because they ask different questions. Electricity meme But I think that is the complicated answer to that question, as far as we know now.
