Paxi – The Greenhouse effect

Join Paxi as he explores the greenhouse effect to learn about global warming.

In this video, targeted at children aged between 6 and 12, Paxi explains the greenhouse effect and what we can do to help.

Earth from Space: Columbia Glacier

Earth from Space is presented by Kelsea Brennan-Wessels from the ESA Web TV virtual studios. In this edition Sentinel-2B takes us over the Columbia Glacier, one of the most rapidly changing glaciers in the world.

Glaciers in decline

Apart from Antarctica, Patagonia is home to the biggest glaciers in the southern hemisphere, but some are retreating faster than anywhere else in the world. This is because the weather is relatively warm and these glaciers typically terminate in fjords and lakes, exacerbating surface melting and causing them to flow faster and lose ice as icebergs at their margins. Traditionally, it has been very difficult to map exactly how fast these glaciers are changing. However, a new way of processing ESA CryoSat swath data now makes it possible to map these glaciers in fine detail. CryoSat has revealed that between 2011 and 2017, there was widespread thinning, particularly in Patagonia’s more northern ice fields. The Jorge Montt glacier, which flows down to the ocean, retreated 2.5 km and lost about 2.2 Gt a year. In contrast, Pio XI, the largest glacier in South America, advanced and gained mass at a rate of about 0.67 Gt a year. However, over the six-year period, the glaciers overall lost mass at a rate of over 21 Gt a year. This loss is adding about 0.06 mm a year to sea level.

From waste packaging to organic food: coming up in Strasbourg

At April’s plenary session, MEPs will look to the future of the EU with French President Emmanuel Macron, while also discussing organic food production, the recycling of waste packaging, greenhouse gas emissions, and the problem of money laundering.

Better energy performance for buildings

The European Parliament set up new goals for member states to ensure that buildings in the EU become energy efficient. Countries will be encouraged to replicate the pioneering experiences of low energy housing tested in Germany or Denmark, among others.

Profiling the wind

ESA’s Earth Explorer Aeolus satellite will be launched later this year to measure the world’s winds from space. The satellite carries one of the most sophisticated instruments ever to be put into orbit: Aladin, which includes two powerful lasers, a large telescope and very sensitive receivers. The laser generates ultraviolet light that is beamed down into the atmosphere to profile the world’s winds – a completely new approach to measuring the wind from space. These vertical slices through the atmosphere, along with information it gathers on aerosols and clouds, will improve our understanding of atmospheric dynamics and contribute to climate research. As well as advancing science, Aeolus will play an important role in improving weather forecasts. The mission will also complement information about the atmosphere being provided by the Copernicus Sentinel missions.
