Last spring, I noted that recent global temperatures seemed to be primarily a combination of a long-term trend and modulation by El Niño and La Niña (here and here). In September, I took this idea one step further and issued global temperature anomaly forecasts for 2012 and 2013 based entirely on a linear trend plus ENSO (here). Today, we see how the 2012 forecast turned out, and update the for ... read more >>

The basic GISS temperature analysis scheme was defined in the late 1970s by James Hansen when a method of estimating global temperature change was needed for comparison with one-dimensional global climate models. Prior temperature analyses, most notably those of Murray Mitchell, covered only 20-90°N latitudes. Our first published results (Hansen et al. 1981) showed that, contrary to impressions f ... read more >>

In my article in Tuesday’s Science Times about the risks of long-term sea level rise, and in an accompanying podcast, I reported on the link between past instances of global warming, caused by natural fluctuations in the climate, and higher shorelines.

Based on a study of these past variations, some scientists believe that even if we stopped burning fossil fuels tomorrow, we would be due for a ... read more >>

The past 12 months were the second wettest on record in the UK, according to data released by the Met Office. The total rainfall for the UK during 2012 was 1,330.7mm (52.4in), just 6.6mm short of the record set in 2000. Most areas were affected by the extreme weather, with thousands of homes flooded and farmers struggling to grow crops in the saturated soil. The latest data comes as analysis says ... read more >>

Jean-Pierre Moreau grows flowers – roses, gladioli and chrysanthemums – out in the desert, about 30km west of Doha. At the request of the emir of Qatar, Hamad Ben Khalifa al-Thani, the Frenchman is producing 4m flowers a year with a workforce of 60, mainly from Nepal and India. Inside the 55,000 sq metres of greenhouses at Roza Hassad, the decor bears little resemblance to the stony, windswept la ... read more >>

President Barack Obama surprised many in Washington, D.C., when he used a portion of his inaugural address to commit to dealing with climate change. "We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," he said. Climate change was rarely mentioned in the U.S. presidential campaign ... read more >>

As Texas' drought wears into its third year, water fights are accelerating within the state as farmers, cities and industry compete for limited supplies from dwindling reservoirs. But many of these seem like small-scale skirmishes compared with the complex and high-stakes battles along Texas' borders that stem from pacts signed decades ago.
Texas is currently locked in a legal conflict over wat ... read more >>

The destruction of the Aral Sea in Central Asia has been called the world's worst environmental disaster. It's not something we should be repeating, especially in a time of growing uncertainty about water resources on our warming planet.

So will the world stand by (and even underwrite the perpetrators) as Ethiopia builds projects that will suck dry one of Africa's largest lakes, and create "wa ... read more >>
