The world may cross the crucial 1.5C global warming threshold in seven years as fossil fuel CO2 emissions continue to rise, scientists warned Tuesday, urging countries at the COP28 talks to "act now" on coal, oil and gas pollution.

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.

World carbon emissions are set to rise 2 percent this year to a new record, scientists said on Nov. 13, dashing hopes that global emissions had already peaked.
