Solar and Oil: 2 Great Tastes That Taste Great Together - Megan McArdle - Business - The Atlantic

Some analysis suggests that photovoltaic generation of electricity could reach grid parity in 75 percent of the world's markets by 2020. As
an economist, my tendency is to think physical scientists are underestimating the speed at which PV could overtake fossil fuels in the production of
electricity.

Climate Change puts green ban on servers

In other words, the [Australian Climate Change] department is housing its power-hungry servers in another location just to achieve its green targets. Because the data is sent over a fibre optic network, it uses 'nice' energy friendly photons, rather than nasty power hungry electrons.

So out of sight, out of mind. The energy is still consumed, but as long as its not on the Nishi Building balance sheet, that's allright.

This contains the usual “And there is a lag between the time when carbon dioxide gets into the air and the full warming effects are felt,” which is a total nonsense.

As earth’s annual temperature cycle demonstrates earth equilibrates changes in forcing quite rapidly, in months, not years. Due to the differing absorption of land and sea and earth’s concentration of land masses in the northern hemisphere earth heats about 3.8°C (6.8°F) from January to July and cools back to January again. Earth reacts with equal alacrity to the varying influences of El Niño and La Niña phases of ENSO. There is no such thing as “years of warming in the pipeline”. Changes in forcing are done and dusted within the year.

UK, Other EU Member States Demand Green Subsidies For Nuclear Power | JunkScience.com

The European Union’s energy ministers are preparing for a clash at their informal meeting in Denmark next Friday (20 April) over whether to set a new target for renewable energy after 2020. The answer could have a direct impact on the future of nuclear energy in Europe.

Cherrypicking – A Comment On The Atlantic Article “Now This Is Interesting: A Climate Prediction From 1981″ By James Fallows | Climate Science: Roger Pielke Sr.

The trend has also been essentially flat since 2002. The Hansen figure indicates the current change since 2002 should be almost +0.2C.

These discrepancies clearly show the Atlantic article did not objectively look into the Hansen prediction.
