What is the latest science telling us about climate change?
The HinduAfter another record-breaking year for global temperatures in 2024, pressure is rising on policymakers to step up efforts to curb climate change. The last global scientific consensus on the phenomenon was released in 2021 through the Intergovernmental Panel on Climate Change, but scientists say evidence shows global warming and its impacts have since been unfolding faster than expected. Critical point The world may already have hit 1.5 degrees C of warming above the average pre-industrial temperature - a critical threshold beyond which it is at risk of irreversible and extreme climate change, scientists say. Research published in October in Nature Climate Change calculated that about 13% of deaths associated with toxic wildfire smoke during the 2010s could be attributed to the climate effect on wildfires. That added concern to scientific findings earlier last year that between 10% and 47% of the Amazon will face combined stresses of heat and drought from climate change, as well as other threats, by 2050.
