The data is in from both NASA and NCDC, and NASA’s prediction of 2010 being the warmest year on record is well on its way to coming true, unless La Niña conditions rapidly develop (see page 15 of the NASA document). It has been:
- the warmest March on record
- the warmest January-March on record
- the warmest April on record
- the warmest January-April on record
Read NCDC’s reports on the March and April global temperatures, NASA’s maps of the January-April temperatures in 2010 as compared to 2005 and 1998 (the warmest years on record, at least until now), and Joe Romm’s excellent summaries.
As Romm says, “After the endless disinformation-based global cooling stories of the past few years, it’s time for the media to start do some serious fact-based global warming stories.” I fully agree. Everyone keep your eyes open, and see whether or not these record-breaking global temperatures are actually covered.

I think that it is the warmest indeed! The temperature is not the way it has used to be. Climate is changing, weather is confusing. Pretty alarming.
We will have to wait and see how the year sums up, but there is a good chance it will be the warmest on record. Any road, the weather patterns of the world certainly are shifting. -Kate
Being nasty here Kate sorry but I cant resist.
Warmest on record for what time frame?? 100 years? 500 years? 1000 years?
Keep up the great work. You are a better gal than I Gunga Din.
No worries. NASA’s records go back to 1880, but we also have proxy records. Those are kind of messy but, as far as anyone can tell, the last decade has been the warmest in the last millennium (see Mann98, Mann08, IPCC TAR, IPCC AR4, Kauffman09, etc). -Kate
