Increasing drought puts the resilience of the Amazon rainforest to the test
Since 2015, the Amazon has been slower to recover from increasing drought events, but, overall, the rainforest still shows a remarkable resilience. New international research led by KU Leuven Earth and environmental scientists shows that forest degra.....»»
Can coal mines be tapped for rare earth elements?
Deposits of designated critical minerals needed to transition the world's energy systems away from fossil fuels may, ironically enough, be co-located with coal deposits that have been mined to produce the fossil fuel most implicated in climate change.....»»
