There is a scientific consensus that climate change is
occurring, and that human activities are the primary
driver. Evidence of climate change includes the
instrumental temperature record, rising sea levels, and
decreased snow cover in the Northern Hemisphere.

greenhouse gas concentrations.

Projections of future climate change suggest further
global warming, sea level rise, and an increase in the
frequency and severity of some extreme weather
events. Parties to the United Nations Framework
