Well I'd say it's obvious it's happening. But as has been pointed out in these discussion previously, has it happened before? Is it just a cycle that the earth goes through?
Maybe it's made worse by our contribution to it, but I don't see how that can be helped. When you still have countries avoiding doing anything to ease it
Yes the earth goes through warm and cold periods, that's natural, we'll have an ice age then a significantly warm period. However, what is happening now is not at all natural, it is not "just a cycle that the earth goes through". What is happening now is not natural at all and is far exceeding anything that would happen naturally. CO2 levels are at the highest
in the last 650,000 years this amount of CO2 (which is the main
greenhouse gas) is not at all natural, and we can definitely do something about it. This has
not happened before,
"The changes in the Pliocene and the [ice ages] took place over a million years, and we are changing the planet now on time scales of hundreds of years."
If you don't believe in climate change or don't believe that it's caused by us and is a major problem I seriously recommend a look at the
nasa climate change website as it is explained really simply here, what causes global warming, what it means, etc. If you just don't care, that's fine, but it's really important and something that people should probably be educated on, as it will have a
massive effect on us and future generations unless we act fast. The main point is that we
can make a difference.The main reason that many politicians and authority figures are not speaking out on this matter, and are not trying to help is because it
costs (Trump even went as far as to call global warming a
"Chinese hoax") the little amount we actually care and are doing about this is scary.
Is climate change natural?
What can we do?
