We should have entered a very gradual cooling phase several centuries ago, based on Milankovitch orbital cycles. Instead global temperature over the past three decades has rapidly increased, and been gradually increasing overall over the past century. This unnatural rise is almost entirely attributable to human activity.
The ice caps continue to melt. With the ice caps melting, global warming continues to be a threat to civilization.
Bush decided not to support it in 2001, because he said it was "too costly".
The theory of global warming became popular in the early 70's. As for how old actual global warming is, is debatable. Some argue that global warming is a natural cycle the earth goes through every so many centuries.
Too much carbon dioxide in the atmosphere is causing global warming. The natural carbon cycle is overwhelmed and can't move out all the extra gas. The extra gas is turning the natural greenhouse effect into an accelerated greenhouse effect, which is causing global warming.
Global warming is the name given to the recent (over 200 years) gradual increase in the temperature of Earth's atmosphere.
Burning natural gas contributes least to Global Warming.
The carbon cycle, when we add extra carbon dioxide by the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity.
The idea that Global Warming is a natural cycle is well understood from paleo.

How is global warming happening
Too much carbon dioxide in the atmosphere is causing global warming. The natural carbon cycle is overwhelmed and can't move out all the extra gas. The extra gas is turning the natural greenhouse effect into an accelerated greenhouse effect, which is causing global warming.
No, it is not a cycle. Natural warmings and coolings happen over thousands of years. The earth has never warmed up so quickly before.
Carbon cycle
Global warming is not natural, it is caused by people. Since there aren't people on Neptune, it cannot have global warming.
Because of a lot of water consumption, acid rain, global warming natural disasters etc.
Global warming is the name given to the recent (over 200 years) gradual increase in the temperature of Earth's atmosphere.
The carbon cycle is the natural way of moving carbon in and out of the atmosphere. The only way it could be used to slow down global warming would be if we planted billions of trees. Trees use photosynthesis to remove carbon dioxide from the air.
Respiration is part of the carbon cycle and does not affect global warming.
Burning natural gas contributes least to Global Warming.
