A recent study suggests that the carbon dioxide emissions that are released into the atmosphere is a main factor leading to climate change and the warming of our planet.
A team of scientists from the Lawrence Berkley National Laboratory in California, conducted a study in which they measured the concentrations of carbon dioxide. The research revealed that the CO2 levels are increasing which is causing the greenhouse effect of our planet.
Scientists first noticed that the levels of CO2 and other greenhouse gases released in the atmosphere are increasing in the 1960s.
After years of lab tests and scientific experiments, it has been proven that these gases are absorbing the infrared radiation emitted by our planet into the outer space. When this happens, the Earth’s temperature begins to rise.
This process is similar to that of a greenhouse, that’s why the scientists called it the greenhouse effect.
Now, more than ever, the researchers have proof that the greenhouse effect is real and is happening in the US.
In order to reach this conclusion, the experts started measuring the radiative force of our planet. The data was collected from various atmospheric research sites from Alaska, Barrow and Oklahoma.
Then, the scientists tracked the infrared radiation that reaches the Earth’s surface and found that the greenhouse gases are responsible for sucking up the infrared energy and throw it back in every direction.
The scientists used special instruments that were able to identify the CO2’s infrared signal, meaning that the researchers were able to tell exactly which of the infrared radiations were sent back by the carbon dioxide.
According to the studies, the carbon dioxide concentration released into the atmosphere increased considerably between 2000 and 2010.
Also, the amount of infrared energy sent back to the Earth’s surface has increased. This means that the more gas is being released into the Earth’s atmosphere, the more infrared energy is being reflected back, instead of being dispersed into outer space.
The researchers published the recent findings in the journal Nature.
