What is global warming considered by some scientists to be such an important problem?

Answer 1

This is because there hasn't been this much change in temperature since the last ice age, and that was several thousand years ago. If we think about it in a short-term perspective, we don't see anything to be worried about. If, however, you look at the temperature history for the Earth for the past million years, you begin to understand why its getting a lot of attention.

To answer your question, its because scientists are worried that such a drastic change is occurring this soon, since these warming and cooling cycles are supposed to be happening a lot slower.

Answer 2

Global warming is changing the climate all over the world and this causes ecosystems to change. Animals may become extinct and there will be mass migrations all over the world, which may cause problems for people who depend of these animals for food. Water levels are rising, which increases flooding near the coasts, but temperatures inland are increasing, which creates more droughts in landlocked areas. The economies of these areas can be destroyed. In short, animals and people will die, more floods and droughts, ecosystems will be changed, and trade can be disrupted.

Answer 3

Global warming is considered an important problem by some scientists because it leads to rising global temperatures, which can cause sea level rise, more frequent and intense natural disasters, disruption of ecosystems, and potential threats to human health and food security. These impacts can have far-reaching consequences for both the environment and society.
