Accounting for Earth’s water cycle

The amount of water on Earth is finite. Sustaining life, this precious resource has been circulating between Earth’s surface and atmosphere for over four billion years, and changing between a liquid, a solid and a gas along the way. Although the total amount of water within the cycle remains constant, the way it is split between its various reservoirs changes continually. With the climate crisis leading to more extreme droughts and floods, the availability of enough freshwater where we need it is a growing concern. How can we be sure that we are using our water resources sustainably?

Counting carbon

The Paris Agreement adopted a target for global warming not to exceed 1.5°C. This sets a limit on the additional carbon we can add to the atmosphere – the carbon budget. Only around 17% of the carbon budget is now left. That is about 10 years at current emission rates.

Each country reports its annual greenhouse gas emissions to the United Nations. Scientists then set these emissions against estimates of the carbon absorbed by Earth’s natural carbon sinks. This is known as the bottom-up approach to calculating the carbon budget.

Another way to track carbon sources and sinks is to measure the amounts of greenhouse gases in the atmosphere from space – the top-down approach. As well as tracking atmospheric carbon, ESA’s Climate Change Initiative is using satellite observations to track other carbon stocks on land and sea.

How we use the land accounts for about a quarter of our greenhouse gas emissions. Forests are the largest store of carbon on the land. Fire acts as a conduit for carbon to pass from the land to the atmosphere. And phytoplankton in the ocean are an important carbon sink.

ESA’s Regional Carbon Cycle Analysis and Processes project is using this information to reconcile the differences between the bottom-up and top-down approaches. Observations are combined with atmospheric and biophysical computer models to deduce carbon fluxes at the surface. This will improve the precision of each greenhouse gas budget and help separate natural fluxes from agricultural and fossil fuel emissions. This work will help us gauge whether we can stay within the 1.5°C carbon budget, or if more warming is in store.

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

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.

Water mission takes on space weather

For well over a decade, ESA’s SMOS satellite has been delivering a wealth of data to map moisture in soil and salt in the surface waters of the oceans for a better understanding of the processes driving the water cycle. While addressing key scientific questions, this exceptional Earth Explorer has repeatedly surpassed expectations by returning a wide range of unexpected results, often leading to practical applications that improve everyday life. Adding to SMOS’ list of talents, new findings show that what was considered noise in the mission’s data can actually be used to monitor solar activity and space weather, which can damage communication and navigation systems.

Gravity mission still unearthing hidden secrets

Despite ESA’s GOCE mission ending over seven years ago, scientists continue to use this remarkable satellite’s gravity data to delve deep and unearth secrets about our planet. Recent research shows how scientists have combined GOCE data with measurements taken at the surface to generate a new model of Earth’s crust and upper mantle. This is the first time such a model has been created this way – and it is shedding new light on processes of plate tectonics, which, in turn, are related to phenomena such as earthquakes and volcanic eruptions.
