Climate Panel Confident Warming Is Underway

From the Washington Post:

The newest international assessment of the consequences of Earth's warming climate has concluded with "high confidence" that human-generated greenhouse gases are already triggering changes in ecosystems on land and sea across the globe.

The second working group of the Intergovernmental Panel on Climate Change, which was charged with tracking the impact of global warming on specific regions and species, plans to release its final report tomorrow in Brussels. The Washington Post obtained a near-final draft of the report yesterday.

That document -- which follows an IPCC study in February that concluded with at least 90 percent certainty that humans are responsible for Earth's recent warming -- provides a more detailed look at how emissions from automobiles, industry and other sources are affecting life around the world.

The draft says "much more evidence has accumulated over the past five years" to indicate that changes such as longer growing seasons and earlier leaf-unfolding and earlier egg-laying by birds are traceable to human activities.
