Climate overturning points are crossed, scientists warn in front of COP30

The global warming crosses the dangerous boundaries earlier than expected with the world’s coral reefs now at an almost irreversible distance, marking scientists on Monday as the first “subversion point” in the climate collapse of the ecosystem.

The warning at the Global Tipping Points report by 160 researchers worldwide, which composes an innovative science to appreciate non -return points, comes just weeks before this year’s COP30 summit on the edge of the Amazon rainforest in Brazil.

The same system of tropical forests is in danger of collapsing as soon as the average world temperature is heated beyond just 1.5 degrees Celsius based on decay rates, the report said, revising the estimated Amazon threshold.

They are also concerned if temperatures continue to rise is the threat of high ocean -ocean disorder called the Atlantic Meridian Traffic or AMOC, which helps to secure mild winters in northern Europe.

“Change is quickly happening now, tragically, in parts of the climate, in the biosphere,” said environmental scientist Tim Lenton at the University of Exeter, who is the main author of the exhibition.

Some positive signs

Lenton scored positive signs when it came to remove fossil fuels that are more responsible for climate change. Renewable energy sources, for example, represented more electricity production than carbon this year for the first time, according to data from the non -profit Think Tank Ember.

“No one wants to be injured and discouraged,” Lenton said. “We still have some service.”

Scientists have asked countries at COP30 in November to work to reduce climate carbon emissions.

Scientists have been surprised by how quickly changes are unfolded in nature, with average global temperatures already heated by 1.3-1.4 degrees Celsius (2.3 to 2.5 degrees Fahrenheit) above the pre-industrial average, according to UN and EU data.

Warm recording

For the last two years they have been the warmest on the earth, with a sea -burning of heat that stressed 84% of the world’s reefs to the bleaching point and, in some cases, death. The coral reefs retain about a quarter of marine life.

To recover corals, people will have to drastically increase climate action to reverses temperatures back to just 1 degree C above pre -industrial average, according to scientists.

“The new report makes it clear that every year there is an increase in the scope of implementation and the magnitude of the negative effects of climate change,” said Pep Canadell, a senior scientist at the Australian climate science center.

The world is currently on a good track for about 3.1 degrees of heat in this century, based on national policies.
