About half of the sea level rise is from melting glaciers on land, and half from the water expanding from heat. Loss of Arctic ice increases warming elsewhere, by not reflecting light over vast areas of ocean. Here's a site with news on individual areas, 3 years ago: Glaciers melting at alarming rates, water problems feared

This column has the first rumour I've heard of Polar bears doing better on average, although obviously, they will migrate to new areas and show a local increase. Eskimo homes are falling into the sea, due to lack of ice and permafrost.

James Lovelock looks at the big picture:
OpEdNews » The Dark Side of Climate Change: It's Already Too Late, Cap and Trade Is a Scam, and Only the Few Will Survive

"He notes that the IPCC and its many powerful computers have successfully undershot all of the indicator trends of climate change so far. Most notably, sea-level rise has outpaced IPCC predictions at a rate of 2 to 1.

Of all the indicators of climate change, Lovelock maintains sea-level rise is the most important. Given the complexity of the millions of interactions within the Gaia system, Lovelock argues it is best to ignore year-to-year temperature fluctuations and instead watch the oceans. The seas, he says, are the lone trustworthy indicator of the earth's heat balance. "Sea level rise is the best available measure of the heat absorbed by the earth because it comes from only two things," he writes. "[These are] the melting of glaciers and the expansion of water as it warms. Sea level is the thermometer that indicates true global heating."

Using Gaia Theory as his lens, Lovelock also examines five dreaded positive feedback loops, those processes now underway that at some point will become ferocious amplifiers of global heating (he finds "warming" too soft a word for the process). Lovelock describes how the most important of these feedback loops already in motion""the loss of reflective ice cover, the death of carbon eating algae as oceans warm, and methane released by thawing permafrost""will soon accelerate the heating trend underway, leading to sudden and dramatic shifts in global climate. Rather than the steady rise predicted by the UN's IPCC, Lovelock is confident the change will resemble economic charts of boom and bust, full of sudden and unexpected discontinuities, dips, and jumps. "The Earth's history and simple climate models based on the notion of a live and responsive Earth suggest that sudden change and surprise are more likely than the smooth rising curve of temperature that modelers predict for the next ninety years," he writes."

The rich countries are doing more to soften their impact, but still lead in terms of sheer impact, especially when you consider that China pollutes to produce for the U.S.
