Much in here I didn't realize o the impact on food supply - including in Canada.
New crops needed to avoid famines

Experimental biotech rice strains can survive prolonged submergence
The global network of agricultural research centres warns that famines lie ahead unless new crop strains adapted to a warmer future are developed.
The Consultative Group on International Agricultural Research (CGIAR) says yields of existing varieties will fall.
New forecasts say warming will shrink South Asia's wheat area by half.
CGIAR is announcing plans to accelerate efforts aimed at developing new strains of staple crops including maize, wheat, rice and sorghum.
At the network's annual meeting in Washington, scientists will also report on measures to reduce greenhouse gas emissions from farmland.
We're talking about the return to large-scale famines in developing countries
"We're talking about a major challenge here," said Louis Verchot of the World Agroforestry Centre (Icraf) in Kenya, a member institute of CGIAR.
"We're talking about challenges that have to be dealt with at every level, from ideas about social justice to the technology of food production," he told the BBC News website.
"We're talking about large scale human migration and the return to large-scale famines in developing countries, something which we decided 40 or 50 years ago was unacceptable and did something about."
The most significant impact of climate change on agriculture is probably changes in rainfall. Some regions are forecast to receive more rain, others to receive less; above all, it will become more variable.
The water supply to farms will become more variable in future
But increasing temperatures can also affect crops. Photosynthesis slows down as the thermometer rises, which also slows the plants' growth and capacity to reproduce.
Research published two years ago shows rice yields are declining by 10% for every degree Celsius increase in night-time temperature.
A study from the International Maize and Wheat Improvement Center (Cimmyt) in Mexico, yet to be published, projects a major decline in South Asia's wheat yield. The vast Indo-Gangetic plain produces about 15% of the world's wheat - but the area suitable for growing is forecast to shrink by about half over the next 50 years, even as the number of mouths to feed increases.
This is likely one of the better looks at the costs right NOW that are hitting parts of North America
A Dream Blown Away Climate Change Already Has a Chilling Effect on Where Americans Can Build Their Homes

A place near the water has been an American dream for a very long time. Fifty-four percent of Americans live within 50 miles of a coast.
This is the year, however, in which the big boys in global finance got religion about climate change. As a result, this American dream -- as far north as the Washington area, and even New York and New England -- is under attack.

Follow the money. Insurance doesn't sound like a world-changer. It seems so banal and prosaic, like reliable electricity or clean water.
Yet without it -- you want a place to live? You cannot get a mortgage without insurance.
You want a job? A commercial enterprise cannot run without insurance.
Never want a drink of water / Til the well runs dry. / Never miss a real good thing / Til he says good-bye.
Turns out you don't have to wait for the waves to lap around your ankles. The climate is changing, Lord knows exactly how fast. But the money is moving pretty quickly.

5 well written pages - I'd hate to be a home owner under those conditions - what a bind - stay put and risk it all with no insurance or lose the dream.
It's looking at the price of insurance, not the costs of global warming.
The cost of replacing property continues to rise, as doesthe number of people claiming. Coastal areas tradiaitonally have a high incidence of property damage. The insurance industry now has a reason to raise the price of insurance to reflect the risk of living in flood prone areas.
Now be a nice Doc and move all of this to the official GHG category, created just for your many global warming topics.
DUBAI, UNITED ARAB EMIRATES The chief executive for Shell berated Washington on Monday for spurning the United Nation's Kyoto agreement on global warming, saying U.S. backing for a global regulatory framework would create incentives for oil companies to reduce carbon dioxide emissions.
For us as a company, the debate about CO2 is over. We've entered a debate about what we can do about it, Royal Dutch Shell PLC chief Jeroen Van Der Veer told a gathering of hundreds of political and business leaders from the Middle East and elsewhere.
Mr. Van Der Veer was asked by an American attending the Arab Strategy Forum whether the energy company's business plans were being hurt by the global backlash against global warming, and the carbon dioxide emissions from burning oil-based fuels considered the prime cause.
Mr. Van Der Veer said energy companies would be ready to partner with governments to solve the carbon problem if there was a worldwide framework to bind governments to the same standards. He said Kyoto protocol, which focuses on 35 industrial countries, was a good start.
I don't know what the GHG thread is, but I for one am glad MacDoc posted the link to this article in a thread that attracted my attention! I already emailed it to several friends who are interested in global warming impacts and may not have seen the Washington Post story.
