What effects will cause global warming to rise exponentially?

Question

I mean something causes something to happen which worsens warming again.

More Co2-hotter-permafrost melts-Permafrost releases even more Co2 that was captured between the ice.

More Co2-Hotter winters-insects live longer and becomes more-forests die out-forests even more unable to cope with rising Co2

Please I need to know for study, any Ideas?

Answer 1

The oceans are a natural carbon sink, but as they warm, they'll be able to absorb less CO2 and may actually begin to release more CO2 than they dissolve.

Retreating ice reduces the albedo effect, which means that more heat is absorbed by Earth's surface and less is reflected.

Methane released from melting permafrost peat bogs that are found in Siberia.

Global warming/warmer temperatures can stress forests and make them more susceptible to fire, pests and diseases. Stressed trees would use less CO2.

Answer 2

The effects of a BAD computer model.

Answer 3

The eclipse of planet earth ,is not as it was before, earth is moved from its orbit, and this new orbit has taken us closer to the sun more than before, this is caused by Atom bombs and hydrogen bombs tested under the ground, which with each explosion the earth was propelled forward to a new orbit, This is the answer of Global Harming

Answer 4

Some other feedback mechanisms include melting snow and ice leading to darker exposed earth which will absorb more heat, and increased atmospheric temperatures leading to higher amounts of atmospheric water vapor, which is another greenhouse gas.

Here's a nice summary of feedback effects:

Answer 5

This is one reason why they needed to rewrite the climate history to make the present temps appear unprecedented - to sell their "runaway warming" thesis.

Bottom line, we didn't have "runaway warming" last time, or the time before that, or the time before that.    

It's an interesting idea that does make some intuitive sense - but it's not what happened during the last few warm periods.
