Climate change is [hello, Congress] still real. California's essential water/politics blogger Emily Green reported this week that 255 of the country’s leading scientists, including 11 Nobel laureates, are doing what they can to get the message across:
(i) The planet is warming due to increased concentrations of heat-trapping gases in our atmosphere. A snowy winter in Washington does not alter this fact.
(ii) Most of the increase in the concentration of these gases over the last century is due to human activities, especially the burning of fossil fuels and deforestation.
(iii) Natural causes always play a role in changing Earth’s climate, but are now being overwhelmed by human-induced changes.
(iv) Warming the planet will cause many other climatic patterns to change at speeds unprecedented in modern times, including increasing rates of sea-level rise and alterations in the hydrologic cycle. Rising concentrations of carbon dioxide are making the oceans more acidic.
(v) The combination of these complex climate changes threatens coastal communities and cities, our food and water supplies, marine and freshwater ecosystems, forests, high mountain environments, and far more.

In related news, California has some of the greediest and most dangerous initiative-pushers on earth. Rule by initiative is the first two or three thousand reasons my poor state is in such bad shape these days.
