Bad News From NASA

Scientists from NASA (the US space agency) and the National Oceanic and Atmospheric Administration, have gathered information from floating devices, positioned in seas across the globe. The scientists found that our planet is trapping twice as much heat now, than was the case in 2005 (https://www.theguardian.com/science/2021/jun/17/earth-trapping-heat-study-nasa-noaa). The study basically looks at energy imbalance. Energy imbalance is the difference between the solar energy absorbed by the Earth's atmosphere/surface and that reflected back into space. This doubling between 2005 and 2019 seems partly related to human-mediated changes and partly down to natural oceanic changes. Most of the excess energy from the sun finishes up in the oceans. The data strongly suggests that the Earth is heating up more quickly than was ever anticipated, with inevitable consequences for climate change.
