Earth's Heat Imbalance Doubled in Two Decades, Scientists Find
Imagine Earth as a bank account where energy is like money.
The sun sends energy in, and some goes back out to space.
But now, we're burning things like coal and gas, which adds extra "heat-trapping" gases to the air, like adding too much spending.
This extra trapping of heat has doubled in the last 20 years, more than scientists expected.
This is changing because of how clouds are changing.
If we keep doing this, the Earth will heat up faster, bringing intense heatwaves, droughts and more intense marine heatwaves.
Scientists are using satellites and ocean measurements to keep track of this, but cuts in funding might make it harder to monitor.
Earth's energy imbalance, the difference between incoming and outgoing heat, has more than doubled in 20 years.
The imbalance is now greater than what climate models predicted, potentially accelerating climate change.
The imbalance is primarily due to increased greenhouse gases trapping heat from the burning of fossil fuels.
Changes in clouds, possibly due to reduced sulfur in shipping fuel, may be a factor in the accelerated imbalance.
Continued monitoring via satellites is crucial, but funding cuts may threaten this essential data collection.
