Tropical Forests Play Huge Role in Inhaling Emissions

Tropical Forests Play Huge Role in Inhaling Emissions

Tropical forests are so critical to fighting climate change that they may absorb up to one-third of all of humans’ fossil fuel emissions and may become more effective at doing so as atmospheric CO2 concentrations increase, according to a new study published in the Proceedings of the National Academy of Sciences. … Read More

Fate of Earth’s Ice Comes Further Into Focus

Fate of Earth’s Ice Comes Further Into Focus

The frigid, ice-covered expanses that make up Earth’s poles are some of the fastest warming parts of the planet as human activity drives up greenhouse gas levels in the atmosphere, altering the global climate. What happens to all that ice isn’t just a concern for these remote, frozen wilds: The ice sheets that cover Greenland and Antarctica hold… Read More

Warming Will Reduce Wheat Production, Research Shows

Warming Will Reduce Wheat Production, Research Shows

Researchers found that wheat production would fall by 6 percent for every 1°C increase in temperatures. The world is now nearly certain to warm by up to 2°C compared with pre-industrial levels, with political efforts concentrated on holding the potential temperature rise to no higher than that limit.… Read More
