Dung beetles help rainforests regrow – but extreme drought and wildfires in the Amazon are killing them off

A new study finds 70% of Amazonian dung beetles were killed by the severe fire and droughts of 2015 to 2016. By spreading seeds and poop, dung beetles fertilize forests and aid regrowth of vegetation.

Weather bureau says hottest, driest year on record led to extreme bushfire season

The Bureau of Meterology says persistent drought and record temperatures were a major driver of Australia's fire activity, and the context for 2019 lies in the past three years of drought.

Using archaeology to understand the past, present, future of climate change

With the dire consequences of climate change looming, archaeologists recognize the importance of communicating their findings on ancient landscapes and the threats that face vulnerable populations.

Floods don’t occur randomly, so why do we still plan as if they do?
