Global warming could be triggering increasingly cold winters in some parts of the world, scientists have claimed. Researchers have discovered a link between rising ocean temperatures, and a large pocket of cold air known as the polar vortex. They discovered that as oceans heat up and melt the Arctic ice, warm air is released that destabilises polar air and sends cold blasts into the atmosphere.
Earth’s subterranean carbon blisters are starting to pop. Carbon inside now-melting permafrost is oozing out, leaving scientists scrambling to figure out just how much of it is ending up in the atmosphere. Whether recent findings from research that attempted to help answer this question are good or bad climate news might depend on whether you see an Arctic river basin as half full of mud - or half empty.
Surging carbon dioxide levels boosted greenhouse gases in the atmosphere to a new high in 2013, amid worrying signs that absorption by land and sea is waning, the UN warned today. "An alarm bell is ringing," Michel Jarraud, head of the World Meteorological Organisation (WMO), told reporters in Geneva.

Welcome to Climate Change Monitoring

The Climate Change Monitoring Services (CCMS) 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.
