Recently, researchers have found that the number of foggy days along the Northern California coast has declined by 24 percent, likely due at least in part to climate change. With less fog, the forest ecosystem will have less water to sustain it through dry summers.

Longer and hotter summers will increase drought and wildfires in Great Smokey National Park, increase stresses on trees, and cause plant and animal species to shift to higher latitudes or altitudes.

A sea level rise of just 2 feet would transform up to 50 percent of the park's freshwater marsh, causing erosion and devastating ecosystems along the coastline.

Warming over the past several decades has reduced the amount of snow on the ground each spring and changed the timing and flow of western rivers. These changes are impacting trees, meadows, glaciers and mountain species in Yosemite National Park.

The National Park Service estimates that spring runoff in the Pacific Northwest now occurs two weeks earlier than in the past, and that, over time, will likely mean an increase in flooding. It also means less water later in the year, and the eventual drying out of many rivers, something that would have far-reaching effects on the ecosystem.

Research by the U.S. Geological Survey found that in recent years the time between Old Faithful's eruptions increased by 15 minutes, in part because of changes in precipitation patterns. Other geysers have experienced similar trends. Extended drought could result in longer intervals between eruptions, and perhaps even cessation of activity in some geysers.

The Summit will take place from December 7-18, 2009. On the brink of runaway climate change, it's time for world leaders to lead, and set us on the path to a low carbon economy.

We realized years ago that it has the potential to wipe out most of the gains the environmental movement has made in other areas. Disruptions to ecosystems will likely harm everything from minke whales to coral reefs to polar bears. Whole forests will be lost, and hundreds of thousands of species will become extinct. Climate change will also bring devastation to people and communities, especially some of the world's poorest.

Part of what we do is to give a voice to these first hand witnesses of climate change. Here is what some of them have to say: Wed, 26 Aug 2009 17:35:55 GMT http://www.greenpeace.org/usa/campaigns/global-warming-and-energy/impacts/climate-voices http://www.greenpeace.org/usa/campaigns/global-warming-and-energy/impacts/ocean-circulation The water in our world's oceans is always moving – pulled by tides, blown by waves, and slowly circulating around the globe by the force of the Great Ocean Conveyor Belt (aka thermohaline circulation). The Conveyor is powered by differences is water temperature and salinity, and one of its most well know parts, the Gulf Stream, is what gives Europe it's relatively mild climate.
