Satellites improve national reporting of greenhouse gases

14.4.2022 9:00   RECAPP-2: analysing carbon budgets

With the climate crisis continuing to tighten its grip, nations around the world are making efforts to reduce emissions of climate warming gases. To track action, countries report their greenhouse gas emissions to the UNFCCC – the body responsible for driving global action to combat climate change. While accurate and consistent reporting is crucial, very few countries exploit Earth observation satellite data to check and improve their estimates. Scientists have now devised new ways of comparing national greenhouse gas inventories with independent measurements taken from space.

Harmony in the Wadden

31.3.2022 9:30   Flying over the Wadden Sea for Harmony

An important milestone in the development of ESA’s tenth Earth Explorer satellite mission, Harmony, has been reached thanks to two aircraft flying in tight formation over the Dutch Wadden Islands collecting key data on sea state and currents. The main purpose of this tricky airborne experiment is to mimic the geometry at which the Harmony satellites will measure various aspects of ocean dynamics to understand how air and the ocean surface interact, which, in turn, will improve weather prediction and climate models.

MTG-I weather satellite passes tests in preparation for liftoff

23.3.2022 9:30   MTG-I pushed into the thermal vacuum chamber

With extreme weather events threatening to be more frequent and more severe as the climate crisis takes grip, it’s never been more important to have fast and accurate forecasts. ESA and Eumetsat are working hard to ensure that there will be a constant stream of weather data from space for the next decades and that these data will arrive faster and be more accurate compared to what we have today. It is therefore fitting that on World Meteorological Day, ESA can be assured that the first of the next generation weather satellites, Meteosat Third Generation Imager, has passed a critical set of tests, paving the way for it to be launched in December.

Attendees will also hear how observing Earth from space supports environmental research and action to combat the climate crisis, learn about novel Earth observing technologies and, importantly, learn about the new opportunities emerging in the rapidly changing sector of Earth observation.

Filling the GOCE data gap unearths South Pole’s geological past

9.3.2022 15:45   Patterns of magnetic rocks and embayment under the ice in East Antarctica

It’s very difficult to know what lies beneath a blanket of kilometres-thick ice, so it is hardly surprising that scientists have long contested the shape and geology of the ancient supercontinent from which East Antarctica formed over a billion years ago. An ESA-funded study can now lay some of this conjecture to rest. Using sensors on aircraft to measure changes in the gravity and magnetic signatures of the different rocks under the ice, scientists have discovered a huge bay the size of the UK formed part of the edge of East Antarctica.

Earth from Space: Snowy Pyrenees

4.3.2022 10:00   Snowy Pyrenees

New research sums up sea-level rise

10.2.2022 11:43   Gorner Glacier melt adds to sea level rise

Sea-level rise is arguably one of the most serious consequences of the climate crisis. While using satellite data to monitor how the height of the sea is changing provides critical evidence for decision-making, satellites are also essential to measuring the individual components, such as seawater temperature and glacier melt, that contribute to the overall rise. Confidence in the accuracy of these separate measures is key. ESA-funded research now confirms that the figures match up.

ESA hosts new office to coordinate global climate modelling push

9.2.2022 9:55   ESA ECSAT

Climate models are an important tool for scientists to understand our past climate and provide projections of future change. As such, they are in increasing demand as part of efforts to avert global warming and reduce risks associated with environmental change. To meet this demand, the World Climate Research Programme will open a new international office in the United Kingdom on 1 March 2022 that will coordinate the programme’s Climate Model Intercomparison Project.

Permafrost thaw: it’s complicated

27.1.2022 16:00   A lake that has partially drained on the Yamal Peninsula

One of the many serious consequences of the climate crisis is that precious permafrost is thawing, and this is unleashing even more carbon to the atmosphere and further exacerbating climate change. However, it’s complicated. For example, sometimes permafrost can thaw rapidly and scientists are unsure why and what these abrupt thaws mean in terms of feedback loops. This makes it difficult to predict the future impact on the climate. Thanks to an ESA–NASA initiative, new research digs deep into understanding the complexities of permafrost thaw and how carbon is released over time.

Mega iceberg released 152 billion tonnes of freshwater

20.1.2022 10:00   A-68A’s position on 17 December

In July 2017, a giant iceberg, named A-68, snapped off Antarctica’s Larsen-C ice shelf and began an epic journey across the Southern Ocean. Three and a half years later, the main part of iceberg, A-68A, drifted worryingly close to South Georgia. Concerns were that the berg would run aground in the shallow waters offshore. This would not only cause damage to the seafloor ecosystem but also make it difficult for island wildlife, such as penguins, to make their way to the sea to feed. Using measurements from satellites, scientists have charted how A-68A shrunk towards the end of its voyage, which fortunately prevented it from getting stuck. However, the downside is that it released a colossal 152 billion tonnes of freshwater close to the island, potentially having a profound effect on the island’s marine life.

Swarm and Cluster get to the bottom of geomagnetic storms

15.12.2021 17:10   Earth's protective shield

The notion of living in a bubble is usually associated with negative connotations, but all life on Earth is dependent on the safe bubble created by our magnetic field. Understanding how the field is generated, how it protects us and how it sometimes gives way to charged particles from the solar wind is not just a matter of scientific interest, but also a matter of safety. Using information from ESA’s Cluster and Swarm missions along with measurements from the ground, scientists have, for the first time, been able to confirm that curiously named bursty bulk flows are directly connected to abrupt changes in the magnetic field near Earth’s surface, which can cause damage to pipelines and electrical power lines.

Sea-level rise is one of the most immediate consequences of climate change, as highlighted recently through urgent pleas from leaders of island nations at the COP26 summit. Global measures of sea-level rise are imperative to underpinning global policy and for strategies to protect coastlines and low-lying lands. Measuring tiny differences in the height of the sea surface from space is no easy task – but that’s exactly what the Copernicus Sentinel-6 Michael Freilich satellite is doing. And, after a year of exhaustive testing, this new mission is now delivering the world’s most accurate data on sea-level rise.

Mapping our human footprint from space

11.11.2021 14:05   Bangkok, Thailand

The world’s population is expected to reach 9.7 billion in 2050, according to the UN Department of Economics and Social Affairs. Urban areas are already home to 55% of the world’s population and that figure is expected to grow to 68% by 2050. Rapid and unplanned urbanisation, combined with the challenges brought by climate change, can lead to an increase in air pollution, higher vulnerability to disasters, as well as issues related to the management of resources such as water, raw materials and energy.

To improve the understanding of current trends in global urbanisation, ESA and the German Aerospace Center (DLR), in collaboration with the Google Earth Engine team, are jointly developing the World Settlement Footprint – the world’s most comprehensive dataset on human settlement.

Tuning in to Earth’s climate

11.11.2021 10:00   Video: 00:03:28

Satellites observe the Earth using a range of wavelengths on the electromagnetic spectrum. Different wavelengths allow us to probe different aspects of Earth’s land, atmosphere and ocean. By sampling the electromagnetic spectrum at multiple wavelengths, we can build a more complete picture of Earth’s complex climate system.

Carbon dioxide monitoring satellite given the shakes

10.11.2021 15:25   CO2M mission

A new satellite destined to be Europe’s prime mission for monitoring and tracking carbon dioxide emissions from human activity is being put through its paces at ESA’s Test Centre in the Netherlands. With nations at COP26 pledging net-zero emissions by 2050, the pressure is on to reduce the amount of greenhouse gases we pump into the atmosphere – but the race is also on to support the monitoring that shows targets are being met. ESA, the European Commission, Eumetsat and industrial partners are therefore working extremely hard to get the Copernicus Anthropogenic Carbon Dioxide Monitoring mission ready for liftoff in 2025. 

Satellites detect large methane emissions from Madrid landfills

High-resolution satellites have detected substantial quantities of methane leaking from adjacent landfill sites close to the centre of Madrid, Spain. Using data from the Copernicus Sentinel-5P mission combined with GHGSat’s high-resolution commercial imagery, scientists from the SRON Netherlands Institute for Space Research and GHGSat discovered both landfill sites combined emitted 8800 kg of methane per hour in August 2021 – the highest observed in Europe by GHGSat.

Satellites pinpoint communities at risk of permafrost thaw

9.11.2021 9:30  

Thawing permafrost in the Arctic is already unleashing methane and carbon dioxide to the atmosphere, exacerbating global temperature rise. As well adding to the climate crisis, this ground, which has been frozen for thousands of years, is becoming unstable and causing serious issues for local communities. For the first time, data from the Copernicus Sentinel-1 and Sentinel-2 missions along with artificial intelligence have been used to offer a complete overview of the Arctic to identify communities and infrastructure that will be at risk over the next 30 years.

Melt

4.11.2021 15:00   Video: 00:31:09

Glaciers across the globe have lost over nine trillion tonnes of ice in half a century. How will glaciers look over the coming decades? “It all depends on what humans are doing now in terms of greenhouse gas emissions:” this is the message one scientist delivered during an ESA-led expedition to the Gorner Glacier in Switzerland – one of the biggest ice masses in the Alps.

As world leaders gather for the 26th UN Climate Change Conference of Parties, watch the exclusive premiere of the documentary that follows ESA astronaut Luca Parmitano, along with a team of glaciologists and climate experts, on their journey across the Alps to learn how rising global temperatures are taking their toll on glaciers.

TRUTHS shapes up

3.11.2021 16:00   Setting the gold standard for climate measurements

ESA’s new TRUTHS mission is taking shape. Highlighted today at COP26, this new mission is moving from its feasibility phase into its preliminary design phase. TRUTHS is set to provide measurements of incoming solar radiation and of radiation reflected from Earth back out into space as traceable International System of Units. These measurements will allow changes in Earth’s climate to be detected faster, and they will be used to calibrate data from other satellites. In effect, TRUTHS will be a ‘standards laboratory in space’, setting the ‘gold standard’ for climate measurements.

ESA and GHGSat support new International Methane Emissions Observatory

3.11.2021 12:32  

In the first 20 years of reaching the atmosphere, methane has more than 80 times the warming power of carbon dioxide. Reducing emissions of this extremely potent gas is, therefore, one of the fastest ways of slowing the rate of global warming, at least in the short term – and at COP26, more than 100 countries have just signed up to the Global Methane Pledge, which aims to limit emissions by 30% compared with 2020 levels.

With both public and commercial satellite data playing key roles in assessing progress on climate action, ESA and GHGSat are supporting the United Nations Environment Programme’s new International Methane Emissions Observatory, also announced at COP26.

As world leaders and decision-makers join forces at COP26 to accelerate action towards the goals of the Paris Agreement, new research, again, highlights the value of satellite data in understanding and monitoring climate change. This particular new research, which is based on measurements from ESA’s CryoSat mission, shows that extreme ice melting events in Greenland have become more frequent and more intense over the past 40 years, raising sea levels and the risk of flooding worldwide.

Space for a Green Future

2.11.2021 15:06   Video: 00:02:12

The climate crisis is the most urgent challenge faced by humankind – affecting every region, continent, and ocean on Earth. Space has an untapped potential to make a difference in tackling the threats and challenges faced by humanity. Satellites watch over Earth continuously, helping us to monitor, understand, model, predict and act on climate change and its related challenges.

As part of one of the three ‘Accelerators’ that will drive Europe’s increased use of space, the Space for a Green Future Accelerator will help Europe act to mitigate climate change. It will provide actionable information, helping form the baseline for effective European adaptation strategies to support the green transition, enabling the European Union to reach its goal of becoming carbon neutral by 2050, and supporting its Green Deal.

Permafrost thaw could release bacteria and viruses

22.10.2021 13:47   Thawing permafrost

When considering the implications of thawing permafrost, our initial worries are likely to turn to the major issue of methane being released into the atmosphere and exacerbating global warming or issues for local communities as the ground and infrastructure become unstable. While this is bad enough, new research reveals that the potential effects of permafrost thaw could also pose serious health threats.

As part of the ESA–NASA Arctic Methane and Permafrost Challenge, new research has revealed that rapidly thawing permafrost in the Arctic has the potential to release antibiotic-resistant bacteria, undiscovered viruses and even radioactive waste from Cold War nuclear reactors and submarines.

Humans to blame for warming lakes

19.10.2021 16:20   Lake Ontario temperature

While the climate crisis is, unfortunately, a reality, it is all too easy to assume that every aspect of our changing world is a consequence of climate change. Assumptions play no role in key environmental assessments and mitigation strategies such as we will see in the upcoming UN climate change COP-26 conference – it’s the science and hard facts that are critical. New research published this week is a prime example of facts that matter. Using model projections combined with satellite data from ESA’s Climate Change Initiative, this latest research shows that the global rise in the temperature of lake water and dwindling lake-ice cover can only be explained by the increase in greenhouse gas emissions since the industrial revolution – in other words, humans are clearly to blame.
