NEW STUDY CONFIRMS THAT CARBON DIOXIDE IS CAUSING THE GREENHOUSE EFFECT

BY JENNA LEWIS / TECH & SCIENCE / 27 FEB 2015

A new study has confirmed what it was already proved through lab experiments that the greenhouse effect is real and it is happening in the United States. A new study showed that pumping carbon dioxide into the Earth’s atmosphere is causing the surface of our plant to warm up. The results of the study were published in the journal Nature.

Scientists at the Lawrence Berkley National Laboratory in California, led by scientist Dan Feldman have measured carbon dioxide concentrations and have obtained proof that the rising levels of CO2 are leading to the greenhouse effect.

Ever since the early ’60s scientists have noticed that the levels of carbon dioxide as well as other greenhouse gases in Earth’s atmosphere are increasing. Lab tests and various other experiments have shown how these gases absorb some of the infrared radiation that our planet emits into the outer space and when that happens, the planet’s temperature rises. The entire process is similar to the way a greenhouse works and that is why scientists named this process the greenhouse effect.

Now there is finally some hard proof that the greenhouse effect is not only real, but that it is happening in the United States. The research team measured the radiative force of the surface of the Earth. The data was obtained from atmospheric research sites in Barrow, Alaska and Oklahoma.

Then, the infrared radiation that comes down to the surface of the Earth was tracked and it was found that the greenhouses gases absorb the infrared energy and disperse it is all directions. The instruments the scientists use managed to identify the infrared signal of the carbon dioxide, which means that they could tell exactly what infrared radiation was sent back by carbon dioxide.

It was found that between 2000 and 2010, the atmospheric concentrations of carbon dioxide rose and at the same time, the amount infrared energy sent back to the earth’s surface also rose. In layman’s terms, the scientists found that more gas in the Earth’s atmosphere meant more infrared energy that got reflected back at Earth, instead of being sent out into the outer space.

Feldman concluded:

I would hope that even people who raise their eyebrows at this whole field can see there is a really robust observation underlying this.
