Researchers also say climate and changes in human emissions may affect levels of base cations.

Scientists are confident this change can be blamed on human emissions because the increase is too big to be explained by natural causes.

Yes, she did hear what could only be a whoop, and a completely human emission.

At the present time, approximately one third of human generated emissions are estimated to be entering the ocean.

The Quoms who deal with human emissions are ranked the lowest.

In the late 19th century, scientists first argued that human emissions of greenhouse gases could change the climate, but the calculations were disputed.

Arrhenius saw that this human emission of carbon would eventually lead to warming.

Therefore, the global concentration of water vapor is not substantially affected by direct human emissions.

Are we going to find out that human emissions are not responsible for the observed warming?

Scientists also knew that human emissions of aerosols could cool the Earth.
