Greenhouse gas emissions hit historic highs, threatening to push the world towards 'unprecedented' levels of global warming, scientists warn. It is reported by The Guardian.

The world is rapidly running out of "

Currently, only about 250 billion tons of carbon dioxide can be emitted to avoid the accumulation of CO2 in the atmosphere, which will lead to a temperature increase of 1.5°C. This is down from 500 billion tons just a few years ago, and at current annual greenhouse gas emission rates of around 54 billion tons per year, this limit will run out well before the end of this decade..

“This is a critical decade for climate change. Decisions made now will affect how much the temperature rises and the extent and severity of the impacts we see,” said Professor Piers Forster, director of the Priestley Climate Future Center at the University of Leeds and lead author of the study..

The rate of annual increase in emissions has slowed down, he said, but more decisive action is needed..

We must change policies and approaches amid the latest data on the state of the climate system. Time is no longer on our side,” he added..

National governments meet in Bonn to prepare for the big UN climate summit Cop28 to be held this November in the UAE. Cop28 is seen as one of the last chances for the world to get on track to meet the 2015 Paris Climate Agreement targets and stay below 1.5°C.

Cop28 president-designate Sultan Al Jaber will arrive in Bonn on Thursday 8 June amid pressure to develop a negotiation plan that will provide a "

Leading the talks, Al Jaber retained his role as head of Adnoc, the UAE's national oil company, which plans to increase its oil and gas production capacity..

Al Jaber previously told the Guardian that his dual role is an asset to negotiations as it will bring " Key figures in the talks, including John Kerry for the US and Frans Timmermans for the EU, praised Jaber.

Campaigners remain dissatisfied, however, and are planning a protest in Bonn on Thursday against an alleged conflict of interest as Al Jaber..

At Cop28, for the first time since the signing of the Paris Agreement in 2015, countries will conduct a "

This analysis probably shows that the world is far off track.. Greenhouse gas emissions continue to rise despite a sharp drop in 2020 as many countries imposed lockdowns due to the coronavirus.

The Intergovernmental Panel on Climate Change estimated in 2018 that the world would need to nearly halve greenhouse gas emissions by 2030 from 2010 levels to stay within the 1.5°C threshold and reach " But this calculation was based on the assumption that the world will reduce emissions by about 7% per year during the 2020s..

As emissions continue to rise, annual emission reduction rates need to be significantly higher to keep the world within 1.5°C.

Report co-author Yori Rogell, professor at Imperial College London, says the world needs to do more.

“This means either pushing back the global target of net CO2 emissions to around 2050 or 2035, or a much deeper reduction by 2030,” says Rogell..

Earlier this year, the International Energy Agency found that energy emissions are showing signs of plateauing.. But only 18 countries have shown sustained reductions in emissions..

One of Al Jaber's top aides, Majid Al Suwaidi, told the Guardian that the UAE will not use the global report to point to countries that are not meeting their obligations under the Paris Agreement or are not cutting emissions fast enough..

“Climate change is one of those things where we are all interconnected. We cannot solve the problem individually. We must solve it as a team. That's what makes it difficult. Therefore, in this discussion there is no simple division into good and bad. Everyone has their own solutions. Everyone has their own ideas. And if we can bring people together around such joint decisions and push the agenda forward, it becomes a really powerful moment..

And that's what we're trying to achieve at Cop28,"

Earlier it was reported that the Russian war against Ukraine is exacerbating the climate crisis at a time when global greenhouse gas emissions are already at an all-time high, according to a report by experts on accounting for carbon dioxide emissions..

The first 12 months of the war would result in a net increase in greenhouse gas emissions of 120 million tons, equivalent to the annual production of a country like Belgium, according to a report to be released on the sidelines of the UN climate summit in Bonn..
