Is global warming hiding underwater?07 February 2014
Is global warming hiding underwater?07 February 2014 Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of t...
Arctic lakes show climate on thin ice03 February 2014
Arctic lakes show climate on thin ice03 February 2014 Ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar imagery show how changes in our climate are affecting high-latitude environments.
El Niño’s impact on continental evaporation22 January 2014
El Niño’s impact on continental evaporation22 January 2014 As global temperatures gradually increase, more water is expected to evaporate into the atmosphere. But using satellite data, scientists have discovered that El Niño-induced droughts have caused global declines in evapotranspiration despite rising tem...
Taking Earth’s temperature13 January 2014
Taking Earth’s temperature13 January 2014 Like thermometers in the sky, satellite instruments can measure the temperatures of Earth’s surfaces. ESA’s new GlobTemperature project is merging these data from a variety of spaceborne sensors to provide scientists with a one-stop shop for land, lak...
New dimensions on ice11 September 2013
New dimensions on ice11 September 2013 Offering new insights into our fragile polar regions, ESA’s CryoSat mission has provided three consecutive years of Arctic sea-ice thickness measurements, which show that the ice continues to thin.
Reflecting on Earth’s albedo06 September 2013
Reflecting on Earth’s albedo06 September 2013 The amount of sunlight being absorbed or reflected by Earth is one of the driving forces for weather and climate. Satellites are providing this information with unprecedented accuracy.
