Global temperatures continue to march upwards
Global surface temperature index. Using 12 month running mean.
Volcanoes and El Nino/La Nina index is shown at bottom.
Jim Hansen and his team of climate scientists at NASA maintain a temperature record of the earth going back to 1880. With the release of their April 2010 data the last 12 months just become the warmest since the instrumental record began.
Or as they say in a draft of a new paper:
"The 12-month running mean global temperature in the GISS analysis has reached a new record in 2010. The new record temperature in 2010 is particularly meaningful because it occurs when the recent minimum of solar irradiance."
"we conclude that there has been no reduction in the global warming trend of 0.15-0.20°C/decade that began in the late 1970s"
Baring a strong La Nina, it also looks likely 2010 will be the warmest calendar year as well.
