Scientists state they have made their initial direct observations verifying an increase in the greenhouse effect over the Earth's surface area, triggered by CO2.They have finalized direct observations that could verify the hypothesis that greenhouses are increasing over the Earth's surface area.

Scientists revealed that CO2 was accountable for the growth of 0.2 Watts per Sq. Meter throughout the period of a decade. Expectedly, the research blamed the increase on nonrenewable fuel source emissions. The escalation in CO2 by growing economies triggered record high emissions throughout 2013, with 35.3 Billon CO2 tons released into the Earth’s atmosphere, out of both nonrenewable fuel source usage and cement production, as based on the research of two international organizations studying the subject.
The increase in CO2 by emerging economies resulted in record high emissions in 2013, with 35.3 billion tons of carbon dioxide dumped into the atmosphere from both fossil fuel use and the production of cement, according to two international agencies that study the issue.
"We're actually measuring the fact that rising carbon dioxide concentrations are leading to the greenhouse effect. This is clear observational evidence that when we add carbon dioxide to the atmosphere, it will push the system to a warmer place," says study lead author Dan Feldman at California's Lawrence Berkeley National Laboratory.
To make their observations, the team used spectroscopic instruments from the Atmosphere Radiation Measurement Climate Research Facility. They also used two other instruments to observe the CO2 contribution to heat by removing heat from clouds and water vapor.
