## Idea

This page is about anthropogenic global warming caused by carbon emissions and other greenhouse gases. To see a list of reports and assessments on global warming, go to Reports and assessments. To see a list of detailed plans for dealing with global warming, and critiques of these plans, go to Plans of action.

## Quick overview

## Details

From Carbon in the Geobiosphere:

Figure shows the growth of world population in 200 years, from 1800 to 2000, and the growth of CO2 emissions from fossil fuel burning and land-use practices. In this period, the global population increased 6-fold, but the industrial and land emissions increased 20-fold. The logarithmic scale of the ﬁgure shows that the population growth rate became faster in 1900 and again in 1950, following the end of World War II. However, the $CO_2$ emissions were growing faster than the population even in the 19th century and their growth accelerated further in the 20th.

The greenhouse effect caused by $CO_2$ has been a topic of scientific discussions for 200 years now, beginning with Fourier in 1827. The following volume collects some relevant papers that have been published in the course of time:

The physicist and science historian Spencer Weart has compiled an online history of global warming, which has also been condensed in book form.
