November 16, 2016

Sentinel-3a is part of a fleet of satellites and was launched in February 2016 to observe Earth's oceans, land and atmosphere. It contains a suite of advanced instruments powered by solar panels. They record different measurements including sea level, temperature and colour. The data is helping us better understand our changing climate and El Niño, a climate cycle that influences the likelihood of extreme weather.

Great to see the bigger picture and how everything connects. Identifying changes before they happen is a huge step forward!

time to get the political response up to the standard of the science. We already know so much about climate change, what we need now is political will.

I think that this is a good idea. If the information is given to fishing companies, though, they should be careful to not overfish in the better areas. Do you agree?

I think that this is good because then we can learn and understand marine and wildlife under the sea.

I like how the data is being used,this is a great experiment and it might get a bit better in the future.

It's all about the data...we need evidence to influence the politicians and world leaders to change opinions and policies to secure the planet's wellbeing and health for future generations.

What do we do when we have collected all possible data like this? What's next?

We should be leaving some of the world intact without human intervention - then we wouldn't need machines like this.

i think we should protect our world becase we just have one. :)
