The [draft U.S. National Climate Assessment](http://ncadac.globalchange.gov/) was [released last week](http://www.wri.org/blog/2013/01/new-national-climate-assessment-shows-america-course-unprecedented-warming), confirming that the climate is changing, that it is primarily due to human activities, and that the United States is already being adversely impacted. These top-line messages should come as no surprise, as they reconfirm the major findings of [previous National Climate Assessments](http://www.globalchange.gov/what-we-do/assessment/previous-assessments) and of the [Intergovernmental Panel on Climate Change’s](http://www.ipcc.ch/) recent reports.

A [new federal report](http://ncadac.globalchange.gov/) reveals alarming statistics on climate change.

According to new data, 2012 was a chart-topping year for the United States – but not in a good way. The National Oceanic and Atmospheric Administration’s (NOAA’s) National Climate Data Center (NCDC) [recently declared](http://www.ncdc.noaa.gov/sotc/) 2012 to be the hottest year on record for the contiguous United States. This year shattered the previous record temperature, set in 1998, by 1.0°F. The year was also marked by 11 extreme weather events that each caused more than $1 billion of damages.

With more than [400 million](http://www.nbr.org/research/activity.aspx?id=181) of its 1.2 billion citizens [without access](http://insights.wri.org/news/2012/08/indias-blackouts-highlight-need-electricity-governance-reform) to electricity, India needs extensive energy development. A new initiative aims to ensure that a significant portion of this new power comes in the form of renewable energy.

Zipcar’s $500 million [acquisition by Avis-Budget Group](http://www.businessinsider.com/avis-buys-zipcar-2013-1) announced last Wednesday is a watershed moment for the car-sharing industry. What will it mean for car sharing?

Experts say that developing nations could [require more than $100 billion](http://www.wri.org/stories/2010/01/summary-studies-estimating-cost-climate-change-adaptation-developing-world) for adaptation each year. Developed countries say that they have already [delivered more than $33 billion](http://www.wri.org/publication/summary-of-developed-country-fast-start-climate-finance-pledges) so far towards this climate adaptation funding.
