Scientists say the unfolding El Niño event superimposed on long-term global warming is a primary driver of this huge spike in global surface temperatures since mid-2023. But the magnitude of the increase shocked many experts, leaving them somewhat puzzled about what else could be behind the remarkable temperature.

Earth's climate has changed throughout history for numerous reasons, but modern climate change is driven by human behavior.

"We're really grateful for the space community and their care at this challenging time — but exploration continues, so we will be back."

Last year, 2024, was the warmest year on record for the planet, easily breaking the previous record set just a year earlier.

Image: It’s “going to look a little different” as it migrates to a more general science site, according to NASA. President Donald Trump has called climate change a “hoax,” and researchers have been archiving environmental data in case it starts to disappear from federal websites.

Climate change and human activities are causing significant disruptions to Earth's natural systems, including the global water cycle. These disruptions have introduced variability and irregularities that challenge assumptions about the stability of geophysical processes.

Some federal websites, including the White House’s, have already deleted climate information, including reports on resilience and adaptation vital to U.S. communities.

As the Trump administration returns to power, NASA faces a crossroads that could redefine its mission for decades to come.

The Sustainable Business Model Challenge is intended to promote innovation by encouraging enterprises to develop sustainable business models supporting climate resilience and informed decision-making.

"The change of seasons causes surface melting far inland from the coastal ice front," glaciologist Christopher Shuman said.

NOAA conducts work and research related to weather and climate and other areas. The return of the Trump administration promises a turbulent and transformative period for NASA and the broader U.S ...

It's actually good news that NASA spotted a sizable asteroid with a (small) chance of hitting Earth in 2032. It means our asteroid-sleuthing telescopes are working.
