A paper published Monday has showed that it is possible to control global warming by using a technology that involves draining of heat-trapping CO2 from the atmosphere. However, it won't provide any significant help to address the issue of climate change.

A second study has come up with results showing that the goal of capping warming of two degrees Celsius above pre-industrial levels could only be achieved by providing a big boost from largely untested carbon removal schemes to even the most aggressive timetable for reducing greenhouse-gas emissions.

Both the studies have presented their results ahead of the summit on climate change in Paris. The studies will encourage representatives of 195 nations to decide swift actions to battle with climate change in order to prevent our planet from its catastrophic impacts.

Geo-engineering will also be the focus in the summit to use it to curb climate change. Extraction of massive quantities of CO2 from the atmosphere through intensive reforestation programmes or carbon-scrubbing technology has gained significant support from various researches that it has great potential to cool the planet.

The second study, led by Thomas Gasser of the Institut Pierre-Simon Laplace, near Paris, showed that keeping earth on a 2 C trajectory is highly unlikely to happen even if nations strike a deal in Paris to adhere to the most aggressive CO2-slashing pathway outlined by UN scientists.

Gasser said their research has made it clear that the use of carbon removing technology is essential even in the case of very high mitigation rates.

"Immediate and ambitious action to reduce CO2 emissions is the most reliable strategy for avoiding dangerous climate change, ocean acidification, and large-scale threats to marine ecosystems", say researchers.
