Critics argue that albedo modification and other «geoengineering» schemes are risky and would discourage nations from trying to reduce their emissions of carbon dioxide, the heat - trapping gas that comes from the burning of fossil fuels and that is causing global warming by absorbing increasing amounts of energy from sunlight.

Black carbon warms the atmosphere because of its ability to absorb radiation from the sun, but its effect can be especially pernicious in polar regions, where, falling on bright ice, the soot diminishes the regions» ability to reflect away heat.

The black carbon spread across the ice darkens its color, absorbing more heat and causing the ice to melt more quickly.

Phytoplankton are tiny organisms that are critical in offsetting climate change because they undergo a process called photosynthesis, whereby they absorb large enough amounts of heat - trapping carbon dioxide to cool Earth's warming environment while releasing much of oxygen we breathe.

Powered by wasted heat from the incinerator, the collectors use fans to suck ambient air into filters, which absorb carbon dioxide.

Environmentally, the fires are a double whammy: They destroy trees that help to slow global warming by absorbing heat - trapping carbon dioxide as they grow.

The Mediterranean Sea is absorbing atmospheric carbon dioxide (CO2) and heat.

The Sun is important because it provides the Earth heat, it creates our daylight by emiting electromagnetic radiation, it allows plants to grow via photosynthesis which in turn absorb carbon dioxide and create oxygen.

In 1861, John Tyndal published laboratory results identifying carbon dioxide as a greenhouse gas that absorbed heat rays (longwave radiation).
