Scientists at the University of Colorado at boulder (USA), predict a catastrophic decline in human intelligence due to the increased carbon dioxide content in the atmosphere, according to the website Phys.org.

Researchers tracked how increased levels of carbon dioxide affect children's learning.

A carbon dioxide reserve 318 meters in depth has been found in a village in the northwestern province of Bolu. The gas has been found to be 98 percent pure.

As of Tuesday, traffic of diesel cars will be banned in the Norwegian capital Oslo.

The measure is taken in an attempt to stop severe pollution of the air in the city, reported BTA.

The ban will be in force until Thursday. It will be valid for municipal roads, as well as national roads crossing the capital.

Researchers have discovered an interconnected series of subsea pools which contain high concentrations of carbon dioxide in the waters off the island of Santorini, Greece.
