So the last ten years have
been the warmest since modern record keeping began last year.
At this time, we announced that 2023 was the warmest year on record.
This year, 2024 has broken that record.
And we're seeing, you know, from science, we understand that increases
in greenhouse gases are driving a trend towards warmer years.
But we also have natural dynamics like El Nino, a La Nina, that can lead
to some years being relatively warm or relatively cooler.
But the last two years have been the warmest that we've measured.
And so the PACE satellite, launched almost a year ago,
and it's looking at tiny things in the ocean, in the atmosphere.
And by looking at these tiny things, we can better understand things
like weather, air quality, harmful algal blooms, fisheries and climate.
So the warming that we're seeing,
this trend towards warmer and warmer years is driven by greenhouse gases.
And so what we know from science
is that how much warmer it gets in the future depends on future emissions.
And when we're seeing with increasing warming and increasing temperatures,
we're seeing an increase in impacts and extreme events.
Some are becoming more frequent, some more intense, and some both.
And we would expect that to continue with continued warming.
So at NASA, one of our most important missions is our home planet.
We've been looking back at Earth from space for decades.
We do this with our crew that are living in the International Space Station.
They can take pictures of Earth from space.
We also have more than two dozen satellites and instruments in orbit,
and they're able to show us things
about the atmosphere, ocean, land, and how it's all interconnected.
And because we've been monitoring Earth for decades, we can see
both what it looks like today and also how it's changed over time.
And we provide all of that information publicly.
So people all around the world know what's happening, where they live.
So NISAR
is going to tell us more about how the surface of the earth moves.
And by looking at that, we can better understand things
like earthquakes, landslides and ice sheet dynamics.
