Where are we in the natural cycle of global warming?

Answer 1

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.

Answer 2

We are currently in a period of accelerated global warming due to human activities, primarily the burning of fossil fuels and deforestation. This has led to an increase in greenhouse gas emissions which trap heat in the Earth's atmosphere, resulting in rising global temperatures, sea level rise, and other climate impacts. Efforts to mitigate and adapt to these changes are crucial to combat further global warming.

Answer 3

The ice caps continue to melt. With the ice caps melting, global warming continues to be a threat to civilization.

Answer 4

Bush decided not to support it in 2001, because he said it was "too costly".
