Six major cloud brands – Apple, Box, Facebook, Google, Rackspace, and Salesforce – have committed to a goal of powering data centers with 100 % renewable energy and are providing the early signs of the promise and potential impact of a renewably powered internet
Six in 10 Americans, including half of all Republicans, said they support regulation of carbon dioxide pollution...Nearly half of Republicans said the U.S. should lead the global fight to curb climate change, even if it means taking action when other countries do not.
Analysis reveals which nations must refrain from exploiting much of their carbon-based energy resources if temperatures are to rise by no more than 2 °C this century.

Canada, Russia, Saudi Arabia and the US cannot burn much of the coal, oil and gas located within their national territories if the world wants to restrain global warming. That’s the conclusion of a new analysis aimed at determining what it will take to keep average global temperatures from rising more than 2 °C this century — a goal adopted during ongoing negotiations under the United Nations Framework Convention on Climate Change.
"If we want to reach the two-degree limit in the most cost-effective manner, more than 80% of current coal, half of gas and one third of oil need to be classified as unburnable," said Christophe McGlade, a research associate at University College London's Institute for Sustainable Resources (ISR) and lead author of the report published in Nature on January 8, during a press conference. Those global restrictions apply even if technologies that can capture carbon dioxide and dispose of it become widespread over the next decade. "Rapid development of [carbon capture and storage] only allows you to produce very slightly more."
According to the study, the vast coal deposits to be found in China, Russia and the US should remain underground, as should most of the natural gas in the Middle East. Nevertheless, natural gas in other parts of the world, such as the US, could play a big role in reducing CO2 pollution — but only if it is used to substitute for even dirtier coal and does not keep more nuclear or renewable sources of power from being built.
The research project started with the UN Intergovernmental Panel on Climate Change's calculation that in order to have at least a 40% chance of keeping global warming below 2 °C, somewhere between 900 and 1,200 gigatonnes of carbon dioxide can be dumped in the atmosphere. Using that budget, McGlade and ISR economist Paul Ekins explored via computer modeling "what fossil fuels should be unused and where are they located," Ekins explained.
Canada holds the world's single largest share of unburnable oil because most of that reserve comes in the form of tar sands, a mix of bitumen and sand that requires burning natural gas to transform it into usable petroleum products. "85% of its reserve base of 50 billion barrels has to remain in the ground," McGlade said.

Pay Attention:
Within minutes of the northern California 6.9 event...
3.0 to 4.0 quakes popped up just north of Washington State on the border with Canada.
Within this same period, a volcano in Alaska lit-up.
Now, just minutes before this article, a 5.1 mag. quake hit just off the coast of Oregon.
Put these events together and you just outlined the Cascadia Subduction Zone; one of the most volatile and dangerous zones along the entire North American continent.

I am not sure about a "40 year" lag but it is usually given as a 20 year lag. But most of the warming is felt quickly, it just takes time for all of it to be felt.
