Do you care about climate change ? Why (not) ?

I think that we have to do something against it because otherwise lots of people, animals and plants will die.
What do you think ?

I don't really care. I believe that it is simply a cycle.... the earth cools, then it warms then cools, etc. And bad weather/climate change happens periodically too. Not saying I think pollution is good, just saying I dont care about whether cows burp or not.

[Casimo]

But the wheather changes/will change a lot - there was not such a gigantic change in the past...

[flyingfisch]

Eh, I beg to differ. The beginnning of the 20th century was a lot like now.

I think there are cycles too, however I think these can cause irreversible changes, eg the ice in Northpole may not form even if the temperature goes very low after a period of global warming.

Climat change ? Holy shit, climat has always changed since beginning of the world !

[Casimo]

But it never changed as much as in the past years...

[Forty-Two]

We actually might cause a premature ice age because of global warming (melting ice->increased freshwater->disrupted ocean currents->glbal cooling), however this is a very bad thing since it is a lot harder to produce food if you farm is under 100 feet of ice...

I think so,too. The temperature hadn't change since the last 15 years, so my opinion is,that the climate change is a big bluff.

Yes it has.

[Casimo]

And that's just until 8 years ago...

[naib864]

I read it in a newspaper, but it can be false, too...

[naib864]

My opinion is clear: This "Climate change" is natural!

[Forty-Two]

The problem is thus: climate change isn't exciting. Scientists have been saying the exact same things for 20 years. Their models have predicted the same outcome for 20 years. And so the media has not really picked up on this for 20 years, since the theory hasn't really changed (although it may by worse than we thought). The only real change is in the dissenters. This is why we have so many stories about people saying that climate change is false.

The other problem is the apathy of good men. It costs a lot less to ignore climate change in the short term, than it does to do something about it. People may say that it is natural, even so, we must take action.

Exhibit A:



Seawater takes up a lot of the total excess heat, not the atmosphere. This means that you might not feel the change in terms of temperature, but if you lived underwater, you would. This will end up in rising sea levels as over 300 million cubic miles of water expands. This is bad for any of you who live only a few feet above sea level (including the coastal plains). Those of you in the mountains, I have good news: your drive to the beach will soon beome a lot shorter.

Exhibit B:



The rising and falling of CO2 levels corresponds to the ice ages. During an ice age, the CO2 levels rise since there is less plant activity. This causes the earth to warm, which causes ice to melt. In turn, the melting ice brings more plant life which decreases CO2 levels. This allows the earth to cool again. At the moment, we are between ice ages, and by looking at the pattern, about at the point where CO2 levels should be rising because of increased ice cover of the earth. However, we are obviously not in an ice age, and yet the CO2 levels are unnaturally going up, unnaturally high. This occurred during the industrial revolution, which released billions of tons of CO2 into the air, but had no relation to this.

Exhibit C:



This shows the net change in glacier thickness (note that this does not measure the actual thickness, just the change). This shows that just over the past 45 years, glacier thickness has dropped almost 15 meters (50 feet). This has to have been caused by an increase in average temperature. Carbon dioxide had- odly enough- been steadily increasing on concentration for the past 200 years.

Then why during the 70's were we warned about global cooling, in the 2000's it was global warming, and now that the earth is cooling again, they can't call it global cooling again so they call it global climate change. the models have not been the same for years.

[naib864]

And this is my opinion to CO2:
I think that the co2 hadn't a so big role, how the politicians suggesting it.Surely, CO2 is doing something with the climate, but I can't imaging, tha CO2 had made this climatic change alone. See: In the history of the earth there are many periods without any ice. So, after an ice age, now a warm period is coming. But maybe it's like the little ice age only a short period, nobody can know this now.

[flyingfisch]

also, has anyone thought that distance from the sun could be a factor?

Global cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere along with a posited commencement of glaciation. This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the scientific understanding of ice age cycles.
