They may be many, many miles up in the air, but satellites have a vital role to play when it comes to analysing our planet and its climate.
In the U.S., for example, NASA says it has over a dozen "Earth science" spacecraft and instruments in orbit, and is conducting research on everything from solar activity to rising sea levels, air pollution and "changes in sea ice and land ice."
The European Space Agency (ESA), based in Paris, is also keen to stress just how important the relationship between space and our climate is.
"The data we get from space in influencing people about climate change is very, very important," Philip Haines, the European Space Agency's head of telecom business development, told CNBC's Sustainable Energy.
The ESA says that climate change is arguably "the greatest challenge facing mankind in the 21st century," and for Haines, the data gathered from up in the heavens is invaluable.
