How satellites tackle climate change

What’s that in the sky?

More than 2,500 objects are launched into space every year. That’s an impressive number.

Each object (satellites, probes, landers, space-station objects, spacecrafts…) has a specific mission.

As per the European Space Agency (ESA): “For more than three decades, Earth-observing satellites have been providing the facts needed to address the challenges of our changing world.”

Satellites play a key role to help tackle climate change. They are designed and equipped to gather highly accurate data on earth from space.

So, what are some concrete examples?

👉A highly publicised topic is to tackle methane emissions (from leaks, waste) in line with the Global Methane Pledge. Satellites provide daily methane maps that pinpoint where emissions are coming from and callout the biggest emitters – taking action!👏

👉Satellites and space scientists help transform farming with imaging that captures the pure spectrum of light from our earth! Partnered with AI, satellites can gather very accurate ground data – including exact soil make-up (nutrients/moisture) of any one field

👉Satellites are collecting specific temperature data in all corners of the world through thermal infrared sensors. They are able to understand nuanced variation and predict climate. This can anticipate droughts, work out land (un)fertility and help with better resource-and-land management (notably water)

👉Satellites collect data from forests (biomass) to accurately monitor forest carbon-stock and how this changes over time

👉There is also a space solar-power project on its way, called SOLARIS. This could collect some major sun rays! SOLARIS is still under development, and has its pros and cons. But it is envisaged to work with highly efficient solar cells, wireless power and automatic in-orbit assembly. Let’s see what the future will bring on this front!

Satellite data is giving us in-depth knowledge that we don’t yet have. This helps scientists and will influence policy-makers to bring about urgent action.🤞

P.S. of course you can say that emissions are released to build, launch and run satellites. But, my article here focuses on the positive outcome of what space can do for us and our planet.🙌
