Summary:

- Global warming, caused by human-induced climate change, is leading to the melting of ice caps and glaciers around the world. This is causing sea levels to rise and disrupting weather patterns.

- However, some scientists believe that this rapid melting of ice could actually trigger the next ice age, by altering ocean currents and disrupting the delicate balance of the climate system.

- This would involve a sudden drop in global temperatures, leading to the formation of new glaciers and ice sheets, and a return to colder conditions across the planet. This could have severe consequences for human civilization and the environment.
