The early spring heat wave will feel more like summer weather.

A warming climate from humans burning fossil fuels and releasing pollution into the atmosphere is increasing the chance that extreme weather will happen.

Christina Dahl is a climate researcher and vice president for science at the non-profit organization Climate Central.

Dahl says a heat wave in April feels warmer than one in August because people's bodies haven't adjusted to hot weather yet.

She advises taking it easy and drinking plenty of fluids.

Methane is a potent greenhouse gas, and governments estimate emissions by taking inventories of sources such as landfills and gas utilities.

But now scientists using satellites have generally found higher levels than those inventories.

Eric Kort directs the Atmospheric Chemistry Department at the Max Planck Institute for Chemistry in Germany.

More than 100 countries have agreed to reduce their methane pollution by 2030 as part of their climate pledges.

After lawmakers failed to pass a Department of Homeland Security budget last Friday, President Trump directed the Transportation Security Administration to pay workers from existing funds.

Immigration and Customs Enforcement officers have been helping the TSA with checking identification and other tasks.

On CNN's State of the Union, Tom Homan said ICE officers might remain at airports.

The TSA says hundreds of workers quit after going weeks without pay.

That's increased security wait times by hours at airports around the country.

Democrats vowed to block DHS funding without reforms after officers killed two U.S.

citizens in Minneapolis.

The Trump administration last month repealed the endangerment finding, a 2009 decision that greenhouse gases from burning fossil fuels endanger public health and welfare.
