Around 140 countries have submitted plans to reduce their emission of greenhouse gases in order to help curb the effects of climate change on the environment. However, many experts believe this month is not enough to produce any considerable impact on the warming of the planet, which is expected to increase global temperatures by two degrees Celsius (3.6 degrees Fahrenheit) compared to conditions during pre-industrial times.

Analysis of nations’ carbon emissions pledges ahead of Paris climate summit shows they would see 2.7C warming by 2100, breaching 2C ‘safety’ threshold

The latest pledges from countries on how they plan to rein in fossil-fuel emissions mean the world is closing in on its goal of keeping temperature increases to 2 degrees Celsius (3.6 degrees Fahrenheit), a group of researchers said.

Earth is on track for average warming of 2.7 degrees Celsius by 2100, higher than the UN target, said an analysis Thursday of country pledges for curbing climate-altering greenhouse gas emissions.

At least 140 countries have submitted their tentative pledges to limit greenhouse gas emissions ahead of the Paris summit. A quartet of climate research bodies has criticized the pledges saying they're "not ideal."

Australian Prime Minister Tony Abbott is set to be confronted by leaders of several Pacific Island nations who seek to take the leader to task for his stance on emissions reduction, according to Monday reports.Abbott has been accused of ignoring calls to push stronger emissions reduction targets from Pacific Island leaders, including the Prime Minister of Tuvalu, Enele Sosene Sopoaga, the President of Kiribati, Anote Tong, and Fiji's Prime Minister Frank Bainimarama, who warned that climate change caused by global rising temperatures could threaten their existence.

So far, 57 countries have submitted their intended climate contributions ahead of the Paris conference - but their combined pledges aren't enough to keep global warming in check. Experts say more ambition is needed.

Nations' plans to reduce greenhouse gas emissions and stop global warming won't come close to curbing what many call the biggest threat of a generation, according to a new report by a consortium of research groups.

Twenty-six countries which include Australia, Mexico and South Korea, have volunteered new carbon-slashing pledges to a global warming pact since the last round of yearly talks in December 2014. But their collective effort in reining in climate change has been negligible, said a sobering report on Wednesday by Climate Action Tracker (CAT), a collective of research institutes.

Inadequate national targets for curbing climate-altering greenhouse gases meant emissions would be "far above" the level required to stave off disastrous global warming, analysts warned Wednesday.Instead of the UN-targeted ceiling of two degrees Celsius (3.6 degrees Fahrenheit) of average warming over pre-Industrial Revolution levels, the world was on track for 2.9-3.1 C by 2100, according to the Climate Action Tracker (CAT), a tool developed by a consortium of four research organisations.
