ESA and NASA join forces to understand climate change

Climate change is, arguably, the biggest environmental challenge the global population faces today. To address this major issue, decision-makers not only need accurate information on how our world is changing now, but also predictions on what may happen in the future. A sound knowledge of how Earth behaves as one system is the foundation to all of this – and the pieces of this complex puzzle come largely from satellites orbiting our planet. To ensure that data from Earth-observing satellites are used to their best advantage, further science and, ultimately, bring the most benefit to humankind, ESA and NASA have formed a strategic partnership for Earth science and climate change.

Swarm yields new insight into animal migration

Using measurements from ESA’s Earth Explorer Swarm mission, scientists have developed a new tool that links the strength and direction of the magnetic field to the flight paths of migrating birds. This is a huge step forward to understanding how animals use Earth’s magnetic field to navigate vast distances.

New satellite data techniques reveal coastal sea-level rise

For the hundreds of millions of people living in coastal regions around the world, rising seas driven by climate change pose a direct threat. In order for authorities to plan appropriate protection strategies, accurate information on sea-level rise close to the coast is imperative. For various reasons, these measurements are difficult to get from satellites. However, new ESA-funded research demonstrates how a specific way of processing satellite altimetry data now makes it possible to determine sea-level change in coastal areas with millimetre per year accuracy, and even if the sea is covered by ice.

CryoSat reveals ice loss from glaciers in Alaska and Asia

As our climate warms, ice melting from glaciers around the world is one of main causes of sea-level rise. As well as being a major contributor to this worrying trend, the loss of glacier ice also poses a direct threat to hundreds of millions of people relying on glacier runoff for drinking water and irrigation. With monitoring mountain glaciers clearly important for these reasons and more, new research, based on information from ESA’s CryoSat mission, shows how much ice has been lost from mountain glaciers in the Gulf Alaska and in High Mountain Asia since 2010.

The curious incident of Swarm and sprites in the night-time

We are all familiar with the bolts of lightning that accompany heavy storms. While these flashes originate in storm clouds and strike downwards, a much more elusive type forms higher up in the atmosphere and shoots up towards space. So, what are the chances of somebody taking photographs of these rarely seen, brief ‘transient luminous events’ at the exact same time as a satellite orbits directly above with the event leaving its signature in the satellite’s data?

Glacier avalanches more common than thought

One tends to think of mountain glaciers as slow moving, their gradual passage down a mountainside visible only through a long series of satellite imagery or years of time-lapse photography. However, new research shows that glacier flow can be much more dramatic, ranging from about 10 metres a day to speeds that are more like that of avalanches, with obvious potential dire consequences for those living below.

Celebrate Earth Day with ESA

At ESA, every day is Earth Day. As we humans continue to subject our home planet to increasing pressures, we are better placed than ever to understand and monitor the consequences of what we inflict. Astronauts onboard the International Space Station give us the human perspective of how beautiful Earth is, while satellites orbiting above return systematic measures to take the pulse of our planet 24 hours a day.

These measurements allow us to understand how Earth works as a system and how human activity is changing natural processes, leading to climate change. This information is fundamental to global climate policy-making through international bodies such as the Intergovernmental Panel on Climate Change and UN Climate Change Conferences, the next being COP26 later this year.
