Space data helps tackle climate change

As scientists warn that weather extremes will become more common, satellite-derived data will be used on two new UK-led projects to monitor, understand and help manage their impact

The first project is a collaboration between the National Centre for Earth Observation (NCEO) and Ordnance Survey (OS), which will provide meaningful insights for policy-makers to manage the impacts of climate change in hot spots across the UK and beyond.

Using NCEO land surface temperature data derived from thermal infra-red sensors in space, OS will then help customers understand and identify how the data can be applied effectively.

The latest UK climate projections show a hot summer like 2018 is likely to occur every other year by 2050, by which time the number of heat-related deaths could more than triple from today’s level in the absence of additional adaptation; from around 2,000 per year to around 7,000. As many as 1.2 billion people around the world could face heat stress conditions by 2100 if current levels of global warming continue.

Insightful evidence

The Earth Observation data used in the pilot will indicate extreme events and locations that may show greater risk to human health, such as cities where heat stress is a particular concern. By providing easier and better access to insightful evidence through the pilot and through working with the Office for National Statistics, the UK public sector will be able to tackle climate change more effectively with accurate geo data from space.

Donna Lyndsay, Innovation Lead, Ordnance Survey, said: “By working collaboratively with the UK Space Agency and leading scientists, OS will use its mapping capabilities to identify areas at greatest risk from global warming using satellite data. The outcome will be to share the learnings from accessing the Earth observation data so that governments and businesses in the UK and globally, have the meaningful insights and evidence to support resilience and adaption plans in relation to the climate crisis.

Identifying risk

The second project will see Telespazio UK, in collaboration with Assimila, developing a pilot of a Climate Risk Index tool, known as CRISP. Using climate data from an ensemble of climate project models, historical reanalysis and Earth Observation data the prototype will focus on two examples – agricultural drought and wildfires – to show insurance companies how to use the data in their own assessments to benefit the finance sector.

The government’s new National Space Strategy pledged to work closely with the financial sector, including identifying the risk of climate change impacts and the UK space sector is keen to lead the way in climate related risk disclosures that impact the financial sector.

CRISP builds on work by the Space4Climate (S4C) Climate Risk Disclosure task group. The S4C work provides the underlying technical capability to determine climate indices – based on consistent identification of extreme climate events and changes in sea level derived from different long-term data records of Earth Observation and climate re-analysis datasets.

Both schemes were unveiled ahead of British ESA astronaut Tim Peake’s attendance at COP26, last year’s UN Climate Change Conference hosted by the UK in Glasgow. Tim visited the S4C stand where he answered questions from young people and talked about how space is helping to monitor and tackle climate change.

Beth Greenaway, Head of Earth Observation and Climate at the UK Space Agency, said: “The UK is leading the way in using space to monitor, understand and tackle climate change. Both of these new projects will provide decision-makers with vital information to help deal with the effects of climate change and improve lives around the world.
