World warning of exceeding 1.5 degrees Celsius threshold

If the 1.5°C threshold is exceeded, researchers fear humanity will be forced to witness a world with serious climate impacts for people, wildlife and ecosystems.

CO2 emissions are now 6% higher than when countries signed the Paris Agreement at COP21

The study found that fossil fuels accounted for 36.8 billion tonnes of the estimated 40.9 billion tonnes _{of CO2} released into the atmosphere this year, up 1.1% from last year. The good news is that some of the world’s major emitters managed to reduce their emissions this year, including the US, which reduced its emissions by 3%, and the European Union (EU), which reduced its emissions by 7.4%.

However, China, which accounts for nearly a third of global emissions, is expected to see its _CO2 emissions from fossil fuels rise by 4% in 2023. Meanwhile, India’s emissions are expected to rise by more than 8%, meaning it will overtake the EU to become the world’s third-largest fossil fuel emitter.

Veteran expert Glen Peters of the Center for International Climate and Environmental Research (Norway) pointed out a bleak reality: _CO2 emissions are now 6% higher than when countries signed the Paris Agreement at COP21 in 2015.

Paradox: Cutting Pollution Warms the Planet?

"The situation is becoming increasingly urgent," author Pierre Friedlingstein of the University of Exeter (UK) told reporters. He warned that the world must act immediately if it is to maintain a chance of achieving the goal of limiting global temperature rise to below 1.5 degrees Celsius.
