Obama Pursuing Climate Accord in Lieu of Treaty
WASHINGTON — The Obama administration is working to forge a sweeping international climate change agreement to compel nations to cut their planet-warming fossil fuel emissions, but without ratification from Congress.

In preparation for this agreement, to be signed at a United Nations summit meeting in 2015 in Paris, the negotiators are meeting with diplomats from other countries to broker a deal to commit some of the world’s largest economies to enact laws to reduce their carbon pollution. But under the Constitution, a president may enter into a legally binding treaty only if it is approved by a two-thirds majority of the Senate.

To sidestep that requirement, President Obama’s climate negotiators are devising what they call a “politically binding” deal that would “name and shame” countries into cutting their emissions. The deal is likely to face strong objections from Republicans on Capitol Hill and from poor countries around the world, but negotiators say it may be the only realistic path....

Models challenge temperature reconstruction of last 12,000 years
...A new study published in the Proceedings of the National Academy of Sciences and led by the University of Wisconsin’s Zhengyu Liu delves into a problem with that pattern—and it’s not what climate models say should have happened....

...The new paper concludes, “If the [Holocene temperature] reconstruction is correct, it will imply major biases across the current generation of climate models. To provide a credible benchmark for future climate models, however, the proxy reconstructions will also need to be reexamined critically.”

Is the SUN driving climate change? Solar activity - 'and not just humans' - could be increasing global warming, study claims
It's not just humans that are to blame for global warming - natural activity from the sun also has an impact on climate change.

This is according to a Swedish research team that has reconstructed the sun's activity at the end of the last ice age, around 20,000 to 10,000 years ago.

The study shows that the sun's variation influences the climate regardless of whether the climate is extreme, as it was during the Ice Age, or moderate, as it is today....
