Over the last month, massive quantities of the Sargassum seaweed have been washing up on the shores of Mexico, Florida in the US and some Caribbean islands, creating a serious environmental problem and causing havoc for the tourist industry. ESA has been tracking this slimy infestation.

An extreme heatwave has hit Europe once again this week, following extreme weather in June. High temperatures are expected to peak today, reaching as high as 39—40°C, with Netherlands, Belgium and Germany recording their highest ever temperatures. Paris reached a sweltering 41°C, breaking its previous record in 1947.

Heatwave conditions catapulted Greenland into an early Arctic summer in June, prompting widespread melting across its icesheet surface, according to researchers at the Danish Meteorological Institute.

With some places expecting to be hit with air temperatures of over 40°C in the next days, much of Europe is in the grip of a heatwave – and one that is setting record highs for June. According to meteorologists this current bout of sweltering weather is down to hot air being drawn from north Africa.

An unexpected and powerful eruption started at Raikoke volcano in the Kuril Islands on 21 June 2019. This image, which was captured on 22 June, shows the brown ash plumes rising high above the dense clouds – drifting eastwards over the North Pacific Ocean.

Most of us probably wouldn't think of describing snow in terms of its grain size. However, grain size is fundamental to the amount of sunlight that snow reflects back into space - its albedo. With both snow and albedo part of the climate system, scientists are applying a novel analytical theory to Copernicus Sentinel-3 data and shedding new light on Greenland's changing albedo.
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth's surface. Ground that has been frozen for thousands of years is also thawing, adding to the climate crisis and causing immediate problems for local communities.

Scientists are gathering in the Azores this week to share findings on how satellite has revealed changes in the height of the sea, ice, inland bodies of water and more. Of concern to all is the fact that global sea level has not only been rising steadily over the last 25 years, but recently it is rising at a much faster rate.

The main proof of long hot and dry spell Europe has been enduring over the last few weeks has been obtained from the Copernicus Sentinel-3 images acquired on 28 June and 25 July 2018.

These Copernicus Sentinel-3 images show how this year's heatwave has taken its toll on vegetation in northern Germany, Denmark and Sweden.

With temperatures soaring and no rain to speak of, Europe is the grip of a heatwave. As well as the havoc that wildfires have caused in countries such as the UK, Sweden and Greece, the current heat is scorching our land and vegetation.

With Europe in the grip of a heatwave and little rain, the scorched ground and dry vegetation is succumbing to fire. Fires have now broken out as far as the Arctic Circle, in Sweden. This animation shows images from the Copernicus Sentinel-2 and Sentinel-3 missions.

This week marks 20 years since the manifesto was signed that gave rise to Europe's Copernicus environmental programme. With seven Sentinel satellites already in orbit delivering terabytes of data every day, Copernicus is the biggest provider of Earth observation data in the world.

The key to monitoring Earth's changing environment and to guaranteeing a consistent stream of satellite data to improve our daily lives is to take the same measurements over the course of decades. But how do you know that measurements from successive satellites, even though identical in build, are like for like?

Launched on 25 April 2018, Sentinel-3B has already delivered some impressive first images from its ocean and land colour instrument, from its altimeter and from the optical channels of its radiometer.
With the radiometer's thermal-infrared channels now turned on, the satellite completes its set of firsts with an image that depicts thermal signatures over southern Italy, the Mediterranean Sea and Sicily.

Launched on 25 April 2018, the Sentinel-3B satellite has already delivered impressive first images from its ocean and land colour instrument and from its radiometer. It has now also delivered data from its altimeter – which means that all of the instruments are working well.
09 May 2018
Less than two weeks after it was launched, the Copernicus Sentinel-3B satellite has delivered its first images of Earth. Exceeding expectations, this first set of images include the sunset over Antarctica, sea ice in the Arctic and a view of northern Europe.
