Climate change is already a global cancer inhibiting the well-being of humans and economic growth throughout the world. Climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer). Climate change may be due to natural internal processes or external forcings, or to persistent anthropogenic changes in the composition of the atmosphere or in land use.
Ocean measurements taken more than 135 years ago during the scientific expedition of HMS Challenger have provided further confirmation of human-produced global warming over the past century.
The biggest piece of President Obama’s second-term agenda is his widely expected plan for the Environmental Protection Agency to issue new carbon regulations for power plants, a move that could bring the United States in line with the greenhouse-gas-reduction goals it agreed to in Copenhagen and open the way for an international treaty to control climate change.

Welcome to Climate Change Monitoring

The RSOE EDIS Climate Change Monitoring Services is taking steps to bring this evidence to the public's attention, with the goal of building support for action to reduce the heat-trapping gas emissions that cause global warming. We have developed - and always updated - a world map, viewable online and also available as an Online Maps, that shows where the fingerprints and harbingers of global warming have occurred in recent years. By showing the local consequences of climate change, it brings the message home effectively.

Frustrated because a friend or colleague says global warming is the future's problem?

Compelling new evidence demonstrates that global warming is already under way with consequences that must be faced today as well as tomorrow. The evidence is of two kinds:

  • Fingerprints of global warming are indicators of the global, long-term warming trend observed in the historical record. They include heat waves, sea-level rise, melting glaciers and warming of the poles.
  • Harbingers are events that foreshadow the impacts likely to become more frequent and widespread with continued warming. They include spreading disease, earlier spring arrival, plant and animal range shifts, coral reef bleaching, downpours, and droughts and fires.
