Report: Some climate damage already irreversible
Many damaging effects of climate change are already basically irreversible, researchers declared Monday, warning that even if carbon emissions can somehow be halted temperatures around the globe will remain high until at least the year 3000.

Latin America, Caribbean Projected Climate Damage $100 Billion Yearly
June 6, 2012 (ENS) - Latin America and the Caribbean face damages of $100 billion every year by 2050 if the global temperature rises just two degrees Celsius over pre-industrial levels, finds a new report to be released at the United Nations Rio+20 summit on sustainable development later this month.
The two degree Celsius rise is often cited by scientists as the level at which world leaders must stabilize the climate to avert the worst consequences of climate change. But a rise of two degrees C over pre-industrial levels is now seen as "unavoidable with significant negative effects in economic activities, social conditions and on ecosystems," according to the report.
Climate damage from warming should tend, to push from the tropics, toward both north and south.
Mexico and Brazil have the largest land distribution just above sea level, making those countries vulnerable to rising sea levels. A rise of one meter (39 inches) in the sea level could affect 6,700 kilometers (4,160 miles) of roads and cause extensive flooding and coastal damage, the report projects.
"Many climate-related changes are irreversible and will continue to impact the region over the long term," said lead researcher Walter Vergara, the Inter-American Development Bank's division chief of climate change and sustainability.

The availability of freshwater resources is particularly sensitive to climate change, yet few indices
consider the sustainability of drinking and irrigation water supplies. There are deep concerns among
populations that rely on glacial-fed water sources about the irreversibility of diminishing water supplies due to glacial melting, and similar fears are felt by millions who rely on monsoon rains (IPCC 2007).
The Tyndall SVI calculates the level of overall natural resource dependence as the rural share of the
population, relating a higher rural share to greater vulnerability (Vincent 2004).
