International may just breach 1.5C warming threshold in 7 years: learn about

The world may cross the crucial 1.5C global warming threshold in seven years as fossil fuel CO2 emissions continue to rise, scientists warned Tuesday, urging countries at the COP28 talks to “act now” on coal, oil and gas pollution.

Battle lines are being drawn over the future of fossil fuels at the UN climate summit in Dubai, with big polluters trying to see off calls for an agreement to phase out the carbon-intensive energy responsible for most of human-caused greenhouse gas.

Fossil fuel CO2 pollution rose 1.1 percent last year, according to an international consortium of climate scientists in their annual Global Carbon Project assessment, with surging emissions in China and India — now the world’s first and third biggest emitters.

They estimated that there is a 50 percent chance warming will exceed the Paris deal’s goal of 1.5 degrees Celsius over multiple years by around 2030, although they noted uncertainties around warming from non-CO2 greenhouse gases.
