Very basic stuff here that anyone following global warming at all is quite familiar with but a good summation of the situation. What is interesting to me is that it has taken this many years for this to finally hit the main stream media.

Panel’s Warning on Climate Risk: Worst Is Yet to Come
YOKOHAMA, Japan — Climate change is already having sweeping effects on every continent and throughout the world’s oceans, scientists reported Monday, and they warned that the problem is likely to grow substantially worse unless greenhouse emissions are brought under control.
The report by the Intergovernmental Panel on Climate Change, a United Nations group that periodically summarizes climate science, concluded that ice caps are melting, sea ice in the Arctic is collapsing, water supplies are coming under stress, heat waves and heavy rains are intensifying, coral reefs are dying, and fish and many other creatures are migrating toward the poles or in some cases going extinct.
The oceans are rising at a pace that threatens coastal communities and are becoming more acidic as they absorb some of the carbon dioxide given off by cars and power plants, which is killing some creatures or stunting their growth, the report found.

Organic matter frozen in Arctic soils since before civilization began is now melting, allowing it to decay into greenhouse gases that will cause further warming, the scientists said.
And the worst is yet to come, the scientists said in the second of three reports that are expected to carry considerable weight next year as nations try to agree on a new global climate treaty. In particular, the report emphasized that the world’s food supply is at considerable risk — a threat that could have serious consequences for the poorest nations.
“Nobody on this planet is going to be untouched by the impacts of climate change,” Rajendra K. Pachauri, chairman of the intergovernmental panel, said at a news conference here on Monday.
The report was among the most sobering yet issued by the intergovernmental panel. The group, along with Al Gore, won the Nobel Peace Prize in 2007 for its efforts to clarify the risks of climate change. The report released on Monday in Yokohama is the final work of several hundred authors; details from the drafts of this and of the last report in the series, which will be released next month, leaked in the last few months.
The report attempts to project how the effects will alter human society in coming decades. While the impact of global warming may actually be outweighed by factors like economic or technological change, the report found, the disruptions are nonetheless likely to be profound.
It cited the risk of death or injury on a widespread scale, probable damage to public health, displacement of people and potential mass migrations.
“Throughout the 21st century, climate-change impacts are projected to slow down economic growth, make poverty reduction more difficult, further erode food security, and prolong existing and create new poverty traps, the latter particularly in urban areas and emerging hotspots of hunger,” the report declared.
The report also cites the possibility of violent conflict over land or other resources, to which climate change might contribute indirectly “by exacerbating well-established drivers of these conflicts such as poverty and economic shocks.”
The scientists emphasized that climate change is not just some problem of the distant future, but is happening now. For instance, in much of the American West, mountain snowpack is declining, threatening water supplies for the region, the scientists reported. And the snow that does fall is melting earlier in the year, which means there is less meltwater to ease the parched summers.

In Alaska, the collapse of sea ice is allowing huge waves to strike the coast, causing erosion so rapid that it is already forcing entire communities to relocate.
“Now we are at the point where there is so much information, so much evidence, that we can no longer plead ignorance,” said Michel Jarraud, secretary general of the World Meteorological Organization.
The experts did find a bright spot, however. Since the group issued its report in 2007, it has found growing evidence that governments and businesses around the world are starting extensive plans to adapt to climate disruptions, even as some conservatives in the United States and a small number of scientists continue to deny that a problem exists.
“I think that dealing effectively with climate change is just going to be something that great nations do,” said Christopher B. Field, co-chairman of the working group that wrote the report, and an earth scientist at the Carnegie Institution for Science in Stanford, Calif.
Talk of adaptation to global warming was once avoided in some quarters, on the grounds that it would distract from the need to cut emissions. But the past few years have seen a shift in thinking, including research from scientists and economists who argue that both strategies must be pursued at once.
A striking example of the change occurred recently in the state of New York, where the Public Service Commission ordered Consolidated Edison, the electric utility serving New York City and some suburbs, to spend about $1 billion upgrading its system to prevent future damage from flooding and other weather disruptions.
The plan is a reaction to the blackouts caused by Hurricane Sandy. Con Ed will raise flood walls, bury some vital equipment and launch a study of whether emerging climate risks require even more changes. Other utilities in the state face similar requirements, and utility regulators across the United States are discussing whether to follow New York’s lead.
But with a global failure to limit greenhouse gases, the risk is rising that climatic changes in coming decades could overwhelm such efforts to adapt, the panel found. It cited a particular risk that in a hotter climate, farmers will not be able to keep up with the fast-rising demand for food.
“When supply falls below demand, somebody doesn’t have enough food,” said Michael Oppenheimer, a Princeton University climate scientist who helped write the new report. “When some people don’t have food, you get starvation. Yes, I’m worried.”
The poorest people in the world, who have had virtually nothing to do with causing global warming, will be high on the list of victims as climatic disruptions intensify, the report said. It cited a World Bank estimate that poor countries need as much as $100 billion a year to try to offset the effects of climate change; they are now getting, at best, a few billion dollars a year in such aid from rich countries.

over 25% of the global 200 fortune companies have a plan in place related to carbon emissions and reductions ... many of these companies are setting targets based on scientific evidence ... many of these companies have already started accounting for carbon down the road ...
what this means is that the desired change required to address this problem is not impossible nor as big as it is made out to be ... what this means is that the lack of progress is purposeful and that unwillingness to act is tied directly to a small group of interests with very powerful influence ...
