"Global emissions at record levels in 2023" - OBM: Temperatures could

The concentration of planet-warming pollutants clogging the atmosphere has reached record levels in 2023, the World Meteorological Organization (WMO) said.

Despite climate change warnings issued by the Intergovernmental Panel on Climate Change since 1990, global emissions have continued to rise in the past decade, reaching their highest point in history. They are expected to exceed the 1.5 degree C warming limit set out in the 2015 Paris Agreement.

The summer of 2023 was the hottest ever recorded, according to data from the European Union's Climate Change Service published in September 2023. The three-month period from June to August surpassed previous records by a wide margin, with an average temperature of 16.8 degrees Celsius, 0.66C above average.

The goal of keeping long-term global warming within 1.5 degrees Celsius is becoming unachievable, climate experts say, with nations failing to set more ambitious goals despite months of record heat on land and at sea.

August was the hottest month on record globally, the third consecutive month to set such a record after June and July, the EU said. Well-above-average temperatures also occurred in Australia, some South American countries and around much of Antarctica in August, the institute said. Meanwhile, the global ocean had its warmest daily surface temperature on record.

By the end of the century, without aggressive climate action, global warming is estimated to reach 2.8C. But even at the current level of warming we may pass several climate tipping points.

The ocean current that moves heat from the tropics to the Northern Hemisphere, for example, is now at its slowest in 1,000 years, putting historic weather patterns at risk, says the latest scientific report, which includes contributions from the UN Environment Programme. and the UN Office for Disaster Risk Reduction.

Nearly half of the world's population is considered highly vulnerable to the impacts of climate change, such as floods, heat, drought, fires and storms.
