Four years ago, torrential rains battered the Southern US, mudslides struck in Peru – and the inhabitants of Canada`s west coast saved up to 30% on their winter heating bills. The cause? El Niño, a huge temperature shift in the Pacific Ocean which spawns climate changes globally. Today, using satellite Earth observation data, scientists are detecting the early warning signs of a new El Niño event and predicting that it will develop over the next 3 to 6 months, bringing climate changes to countries th

The Scotia Sea, located between the Antarctic and the tip of South America, acts like a ‘blender’ on the very cold ocean waters that influence global ocean circulation patterns and ultimately climate, according to new research from the University of East Anglia (UEA) and published today (28 February) in the international journal Nature.

The research, carried out by Dr Karen Heywood, Dr David Stevens and Dr Alberto Naveira Garabato, shows that the dense, cold waters formed in the Weddell Sea

Europe’s showpiece in climate monitoring is called Envisat. Fully equipped, the largest, most complex, and most powerful Earth observation satellite of the European Space Agency (ESA) is 25 meters high, ten meters wide and weighs over eight tons, scheduled for launch in the night of 28 February /1st March on an Ariane 5 launcher.

Europe’s flying behemoth is on the trail of climate change. It will deliver data about global warming, ozone depletion and climate change for at least five

Using tiny bone fragments from fossilized fish, scientists have traced the roots of the climate phenomenon known as El Niño, the intermittent warming of ocean waters off the coast of Peru that can affect weather worldwide. According to a report published in the current issue of the journal Science, modern El Niño conditions arose around 5,000 years ago.

Previous research based on fossilized mollusk remains had suggested that El Niño conditions did not exist thousands of years ago, but those

Thanks to ion propulsion, the Artemis mission is turning near-defeat into a success story. Nominal operations could start this summer, with ESA’s satellite, manufactured by Alenia Spazio as prime contractor (I), playing a significant role in the pursuit of high technology and advanced telecommunications.

On 12 July 2001, 30 minutes after lift-off from Europe’s spaceport in Kourou, French Guiana, it became apparent that the Ariane 5 launcher had propelled the Artemis satellite into a transf

Eddies appear in the ocean like in the atmosphere. Atmospheric eddies are short-lived, extremely speedy, and often very hazardous. Oceanic eddies are slower and can be observed only with the use of special equipment, but these eddies gently mixing ocean waters affect the climate in general.

For more than ten years specialists from the Pacific Institute of Oceanology in Vladivostok have observed the oceanic eddies formed at the confluence of two largest undercurrents in the west of the Pacif
