India and China are reportedly among the world's seven countries that are responsible for global warming, a new study has found.
The study conducted by Concordia University found that the United States, China, Russia, Brazil, India, Germany and the United Kingdom as the biggest contributors to the rising temperatures of the world.
It has been found that these countries were collectively responsible for more than 60 percent of pre-2005 global warming.
The study, under the leadership of an associate professor in the Department of Geography, Planning and Environment, Damon Matthews, ranked the US as an unambiguous leader, responsible for a global temperature increase of 0.15 C, which is close to 20 percent of the observed warming.
China and Russia account for around 8 percent each; Brazil and India 7 percent; and Germany and the UK around 5 percent each.
It was found that less industrialized countries, including Brazil and Indonesia, ranked so highly because their positions reflect carbon dioxide emissions related to deforestation.

Matthews and his colleagues experimented with scaling the emissions to the size of the corresponding area. Western Europe, the U.S., Japan and India are hugely expanded, reflecting emissions much greater than would be expected based on their geographic area. Russia, China and Brazil stay the same.
The study also revealed that amongst the 20 largest total emitters, developed countries occupy the top seven per-capita positions, with Canada falling in third place behind the UK and the United States and this ranking places China and India to the bottom of the list.
