Global carbon emissions are set to hit an all-time high of 37.1 billion tonnes of CO2 in 2018, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project.
A separate study found that Greenland's ice sheet was melting at its fastest rate for at least 350 years, which could lead to a rapid increase in sea levels.
It marks the second year in a row in which the amount of pollution being put into the atmosphere has risen, after 2017 saw carbon emissions increase 1.6 per cent.
A strong climate and health call to action for COP24 was issued by organizations representing over 5 million doctors, nurses and public health professionals and 17,000 hospitals; from over 120 countries.
Meanwhile, emissions in the United States - which accounts for 15 per cent of the global total - are also set to rise around 2.5 per cent in 2018, following several years in which Carbon dioxide has fallen thanks to an increased reliance on renewables and gas.
The countries that signed on to the Paris accord, including Canada, committed to a goal of limiting the average global temperature rise to between 1.5 and 2 degrees Celsius.
"Emissions need to peak and rapidly decrease to address climate change". "We think that emissions are probably still going to go up for some years unless things change drastically".
The report is the second concerning update inside 24 hours, after the International Energy Agency yesterday warned energy-related carbon emissions are set to rise in both industrialised and developing economies this year.
The trend indicates that if they fail to cut their emissions more drastically by 2020, the burden of mitigation will fall on developing countries, including India, post-2020 despite their much lower per capita emission as compared to the United States and 28 European Union (EU) nations. "Fossil energy needs to be phased out and efforts to decarbonise need to be expanded throughout the economy".
The researchers said global carbon dioxide emissions have China's carbon emissions account for 27% of the global total and have increased an estimated 4.7% in 2018.
Meanwhile, emissions from the rest of the world - which makes up the remaining 42 per cent of global Carbon dioxide emissions - are also expected to grow by 1.8 per cent this year.
In a broader sense, reversing the upward trend in global emissions comes down to two major challenges, Peters suggested-strengthening reductions in places where emissions are already declining, and reducing growth in places where emissions are still climbing.
The day after Thanksgiving, the Trump administration released a almost 1,700-page report cowritten by hundreds of scientists finding that climate change is already causing increasing damage to the United States.
China's top planning agency said Wednesday that three areas - Liaoning in the northeast Rust Belt and the big coal-producing regions of Ningxia and Xinjiang in the northwest - had failed to meet their targets to curb energy consumption growth and improve efficiency previous year.
Worldwide, renewable energy continues to see remarkable growth.
"Even as we witness devastating climate impacts causing havoc across the world, we are still not doing enough, nor moving fast enough, to prevent irreversible and catastrophic climate disruption", Guterres said.
