More than 11,000 scientists from around the world have backed research that says the world is facing a climate emergency. The study, based on 40 years of data, says governments are failing to address the crisis. Writing in the journal Bioscience, the group says scientists have a moral obligation to warn humanity of catastrophic threats. Doctor Thomas Newsome from the University of Sydney is one of the lead authors. He says it’s not too late to act, but time is running out.

The Earth’s climate is changing. Models show us how.
The world’s climate is complex — land, oceans, atmosphere, all in a constant state of change. Feedback loops, seasonal cycles, complicated energy exchange mechanisms … how do you make sense of it all to figure out what’s going on?
Alex is a climate scientist and a physical oceanographer working on the role of the ocean in the climate system, in particular how the ocean will change in the future and what effect this has on the critters that live there. His research includes understanding how the East Australian Current will accelerate in the future, simulating how we can use virtual tuna in ocean simulations to guide sustainable fisheries and explain how a rising air in the tropical Indian Ocean can generate a marine heatwave in the South Atlantic.

Economists are warning that climate change isn’t just an environmental emergency, it could put a dent in global GDP.
A new study from the IMF, the University of Cambridge and the University of Southern California predicts that unless we slow down the effects of climate change, GDP per capita will drop significantly across the world.
