Global Model Confirms: Cool Roofs Can Offset Carbon Dioxide Emissions and Mitigate Global Warming

Can light-colored rooftops and roads really curb carbon emissions and combat global climate change?

The idea has been around for years, but now, a new study by researchers at Lawrence Berkeley National Laboratory that is the first to use a global model to study the question has found that implementing cool roofs and cool pavements in cities around the world can not only help cities stay cooler, they can also cool the world, with the potential of canceling the heating effect of up to two years of worldwide carbon dioxide emissions.

‘Arctic Climate May be More Sensitive to Warming than Thought’

A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth’s atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.

Rise in Global Temperatures and Extinction of the Lizards

For many lizards, global climate change is a matter of life and death.

After decades of surveying Sceloporus lizard populations in Mexico, an international research team has found that rising temperatures have driven 12 percent of the country’s lizard populations to extinction.

CCS- carbon dioxide capture and storage

By ShamsSeptember 25, 20081 commentEnvironment, ScienceCapture, carbon dioxide, CCS, CO2, Schwarze Pumper. Germany, transport and storage, Vattenfall

Fossil fuels (mainly coal powered power stations) emits about one-third of all carbon dioxide (CO₂) that goes to the atmosphere every day. As it’s a well-known greenhouse gas, therefore many attempts are being made to capture it from the power stations and to store it underground in the geological formations. The aim is therefore towards ‘zero emission’.
