Question

Why do many scientists believe that humans have contributed to climate change?

Answer 1

Answer:

Scientist believe that humans have contributed to Global warming because if you take a look at what we have built and what we use you can see how we destroy the Earth.

Explanation:

Example, Power plants create gases called greenhouse gases that go into the Atmosphere.This is causing the ozone layer to decrease and disappear.We use a lot of carbon too.Extra carbon is bad for Earth.Some scientists argue that this is 100% humans fault.Personally,I don't believe so, but Ricky Perry. Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of global warming is because of human activity, I think on its face, is just indefensible”.

Answer 2

Answer:

The time to act is now. But action isn't easy: many powerful industry interests have hindered climate solutions and spread dangerous myths about climate change.

One of the preferred tactics these groups use to sow confusion is to promote studies that either ignore or misrepresent the evidence of thousands of articles published in well-established and well-respected scientific journals, which show that global warming is happening and that it is caused by humans.

No matter how much contrarians try to cloak reality, the evidence is not going away.
