Robert Redford: I will be ‘devastated’ if EPA riders pass - The Hill's E2-Wire
The actor, a longtime environmentalist, said any moves to prohibit the EPA from implementing climate and other regulations would be devastating for himself and the country.



He vowed to try to stop it. 

"All I can do is try," he told The Hill. "I'm going to be devastated if something happens and I think the country will be devastated too. Particularly future generations will be devastated. It's a very narrow way to be."

Meat production is also disastrous for the environment. Senior UN Food and Agriculture Organisation official Henning Steinfeld stated that the meat industry is "one of the most significant contributors to today's most serious environmental problems". Nitrous oxide is about 300 times more potent as a global-warming gas than carbon dioxide. According to the UN, the meat, egg and dairy industries account for 65 per cent of worldwide nitrous-oxide emissions.

"ESA's CryoSat mission will provide precise data about ice thickness and, over time, it will measure changes in detail. Such data are needed to make informed decisions to carefully manage this fragile and rapidly changing environment."
[Although we don't know how thick the ice is, we somehow know the total ice volume?]: Polar Science Center » Arctic Sea Ice Volume Anomaly
Sea ice volume is an important climate indicator. It depends on both ice thickness and extent and is therefore more directly tied to climate forcing than extent alone. However, Arctic sea ice volume cannot currently be observed continuously. Observations from satellites, Navy submarines, moorings, and field measurements are limited in space or time. The assimilation of observations into numerical models, currently provides one way of estimating sea ice volume changes on a continuing basis. Volume estimates using age of sea ice as a proxy for ice thickness are another useful method (see here and here). Comparisons with observations help test our understanding of sea ice conditions in the Arctic.
