How much has the global average temperature warmed over the last 100 years?

Averaged over all land and ocean surfaces, temperatures have warmed roughly 1.33°F (0.74ºC) over the last century, according to the Intergovernmental Panel on Climate Change (see page 2 of the IPCC’s Climate Change 2007: Synthesis Report Summary for Policymakers (PDF)).

What has happened to global temperatures over the last 10000 years?

After the last ice age 20,000 years ago, average global temperature rose by about 3°C to 8°C, over a period of about 10,000 years. We can link the rises in temperature over the last 200 years to rises in atmospheric CO2 levels. Rises in temperature are now well above the natural cycle of the last 800,000 years.

What will the temperature be in 100 years?

Even if the atmospheric composition of greenhouse gases and other forcing agents was kept constant at levels from the year 2000, global warming would reach about 1.5℃ by the end of the century. Without changing our behaviour it could increase to 3-5℃ by the end of the century.
