Will Earth explode or be thrown out of orbit if global warming continues?

No. All that will happen is that the mean average temperature of the atmosphere will increase, resulting in ice caps melting, which will cause sea levels to rise, and triggering climatic changes. These changes will alter the type of crops which can be grown in a given location, cause species to change their migratory habits, and possibly change weather patterns.

The Earth itself, the planet, will not be affected, nor will the planets orbit around the Sun be affected With regard too the oceans rising - the impact will not be entirely due to the added water generated by melting ice caps. The water in the oceans will become less dense due to its being warmer and less saline. Less dense water will not have the weight to compress the deep waters as tightly and they will expand slightly.It is estimated water at the bottom of the Pacific is compressed by about 1.08% at 4000 m.

Releasing this pressure by even a small amount could result in a depth increase of several meters (Reference:See the link below. ).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
