Corals on Australia's iconic Great Barrier Reef experienced a catastrophic die-off following the extended marine heatwave of 2016, a study has found.

TRICHY: A light-weight satellite built by a 17-year-old aspiring medical student from Trichy will study the effects of air pollution and global warming in various regions including major cities in

Global warming is rapidly emerging as a universal threat to ecological integrity and function, highlighting the urgent need for a better understanding of the impact of heat exposure on the resilience of ecosystems and the people who depend on them. Here we show that in the aftermath of the record-breaking marine heatwave on the Great Barrier Reef in 2016, corals began to die immediately on reefs where the accumulated heat exposure exceeded a critical threshold of degree heating weeks, which was 3–4 °C-weeks.

With global warming, we can make predictions and then take measurements to test those predictions. One prediction (a pretty obvious one) is that a warmer world will have less snow and ice.

A new IMAS-led study has revealed a previously undocumented process where melting glacial ice sheets change the ocean in a way that further accelerates the rate of ice melt and sea level rise.

Efforts to reduce dangerous air and climate pollutants by Latin American and Caribbean countries could reap immediate and long-term benefits for health, food security and the climate according to the first ever Integrated Assessment of Short-lived Climate Pollutants (SLCPs) for the region.

Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool and salinify waters on the Antarctic continental shelf. Polynya activity thus both limits the ocean heat flux to the Antarctic Ice Sheet and promotes formation of Dense Shelf Water (DSW), the precursor to Antarctic Bottom Water. However, despite the presence of strong polynyas, DSW is not formed on the Sabrina Coast in East Antarctica and in the Amundsen Sea in West Antarctica.
