Why does climate change matter?
NASA
We Asked a NASA Scientist.
Well, it's happening.
We look at the Earth from space and we measure it on the ground.
And what we see is that the planet's climate is changing.
The last years have been the warmest since modern record-keeping began.
It's serious.
Even a little change in temperature can have big effects.
And we're seeing some of those effects now.
Sea levels are rising.
We're seeing more extreme events like heatwaves and heavy rainfall and wildfire.
And we know that a lot of those effects are going to increase with more warming.
These changes are impacting decisions that some people make every day,
like a farmer thinking about what crops to grow or a homeowner thinking about flood risk.
But there's hope.
There are scientists at NASA and around the world that are researching this.
We know more about our planet than we have ever before,
and we learn more every day.
So we know why climate is changing.
We know that it's due to increasing greenhouse gases from human activity.
We also have tools that can help us better understand
and better prepare for future climate change.
So we develop computer models that help us understand how much it might change in the future.
And we're also developing technologies here at NASA and around the world
that can help us limit future warming or respond to the warming that we're experiencing.
So why does climate change matter?
It's real.
It's serious, and it's here.
