Developing nations drive big change in carbon growth rates. 1970-1999: 1.6%/yr. Post-2000: 3.1%/yr @deeplycloudy

Financial crises explain many of the dips in historical carbon emissions from fossil fuels

How do the new (RCP) & old (SRES) scenarios we're using for climate projections compare to actual carbon ems?

How long has Texas been warming? Annually: since 1934. Winters: since 1938. Summers: since 1952.

How much of obs sea level rise is due to ice melt vs. thermal expansion? From http://bit.ly/tjScPl via @skepticscience

2011 will be the warmest La Nina year ever, estimated 10th warmest on record. Thx @skepticscience

Me, when trying to give a serious answer to an unintentionally funny question..

Why is future #climate change uncertain? 3 main reasons, clearly illustrated by #climate scientist @ed_hawkins #FF

Even the lady in the supermarket's heard of #climate scientist @MichaelEMann & his famous "hockey stick"

Estimated historical emissions vs future IPCC scenarios--how are we doing? You be the judge!

Travellers through the DC Reagan airport will be learning about #climate change thanks to @garybraasch's photos

TX #PKfire continues, more areas being evacuated. Our 2nd huge fire in 5 months. 30+ homes, 7k acres so far.

@ChairmanAl 2000s warmest decade on record. 2010 tied for warmest yr. R u talking abt "cooling since 1998" myth?

I thought this was funny. Thanks @postcarbon !

thanks! We are hoping it escapes. This is the view from our lake place this afternoon @arthursmith @Lion333

Just got back from 3+ weeks on the road. Durham (NH), Montreal, Toronto, Dallas, and one blessed weekend in Taos.
