Does Leonardo Decaprio know anything about global warming?

Question

He actually claimed, "the last ten years have been the hottest years ever recorded." There is plenty of evidence that global temperatures are caused solar activity. There is very little scientific evidence that temperatures are affected by emissions --even those are disputable due the correlation with solar activity. Also, does a 1 degree change in temperature truly affect the world in a negative way? One day we will all laugh as much as i do at Global Warming extremism. But it's really not funny. It is bound to cost people their jobs.

Answer 1

Let's put it this way - some scientists may be idiots, but is it likely that most of them are? They know very well that the Earth has warmed and cooled in the past. Yet most scientists who know about such things firmly assert that most of the recent global warming is a human-caused phenomenon. There's a couple reasons why:

THE RATE OF CHANGE. Biologists have measured how long it takes animals and plants to 'migrate'... or to change their habitats so they same in roughly the same kind of environment. You would think that pretty much all of them would be fairly evolved to make such changes as the Earth's environment changed throughout its history. Yet the rate of temperature increase we're seeing far outstrips most of their abilities to compensate. If it continues unabated, we may see huge-scale decimations of plant and animal wildlife.

COMPARISONS TO THE PAST. Right now the carbon dioxide level is VERY high. Our most accurate measurements can only reach back 650,000 years, and it's never been as high during that time as it is now. Using less accurate measurements, you would have to go back 40 million years to get to an analogous carbon dioxide level. Atmospheric methane shows a similar trend. Most of this change can be traced back to human activity chronologically.

WE KNOW WE CAN AFFECT THINGS GLOBALLY. Remember that hole in the ozone layer? It's still there, and bigger than ever, actually. Not to mention extinction of species we know we've caused, habitats we know we've wiped out, and other large-scale changes.

But sweeping that all aside for a second, suppose we're NOT at fault for ANY of it. Does it really matter? Wouldn't it behoove us to counteract a global temperature change before it inhibited our activities too severely. To put it another way - even if we haven't affected global systems in the past, it is in our interest to do so in the future. Even if global warming is completely natural, not stopping it could have major negative side effects!

Answer 2

So if you disagree with global warming theories (or Leonardo DiCaprio), then you should continue to waste and pollute because it's not a problem yet?

Personally, I believe that global warming is a very serious concern and we will pay for our neglect if we don't change our ways.

But even if I didn't, I would still want to treat my planet with respect and not be a wasteful human being. Following the guidelines and taking into consideration the recommendations on how to reduce harmful emissions and energy usage won't turn you into a Hollywood liberal. It just makes you an intelligent and caring individual.

Answer 3

For the most part, I agree. There is a lot more to global warming than the greenhouse effect, and a lot more to greenhouse warming than CO2. I did not read his statements to know if you are taking him out of context or not, but to say, "the last ten years have been the hottest years ever recorded," is either gross simplification or ignorance. There is a great deal of geological evidence that show global temperatures have, in the past, been a great deal warmer, and a great deal cooler than they are now. You are, however, mistaken in believing that a one degree change is insignificant. This doesn't that it's just 1 degree warmer outside than normal.

To say global warming is not happening is incorrect. But to blame it exclusively on the burning of fossil fuels, or even greenhouse warming in general, is unwise. I believe that a lot more is going on than meets the eye, and unfortunately, I believe a lot of what is happening is mostly political. I guess to make my long winded story short, Warming is much more complex than the human causes of it, and to blame soely on human activity is like cutting your nose off to spite your face.

Answer 4

I believe in global warming now - my professors in natural resources grad school were talking about it in the 1960s, based on the CO2 observations that Charles Keeling had made at Mauna Loa observatory starting in the 1950s. And everything I've read as a journalist since then has persuaded me that yep, my natural resources professors were right -- although not in all the details. As for Al Gore and Leonard DiCaprio, I haven't seen any movies made by either one of them, and I don't pay much attention to their lifestyles. I do think they both probably fly in airplanes too much -- more than I think I should, anyway, given the bad effect fossil fuel consumption has on the climate.

Answer 5

i think he has a general theory, but he is asking the question for a, publicity, b, to get a better understanding of how to help the earth

Answer 6

well he does have an opinion if he wants to post something about global warming let him.obviously he really cares about global warming let him encourage other people to care about it to.
Everybody should care

Answer 7

no...he doesnt....he picked an enviromental topic from his backside and ran with it, seems like nowadays every actor needs a cause..... he should have picked one thats actually true

Answer 8

leonardo dicaprio doesnt know anything about anything. and hes a sucky actor

Answer 9

I don't think he's really into the environment. I think he's more into himself. ~~
