Tropical forests play major roles in regulating Earth’s climate, but there are large uncertainties over how they’ll respond over the next 100 years as the planet’s climate warms. A multi-institutional project led by Berkeley Lab, called NGEE-Tropics, will combine field research with model development to represent how tropical forests interact with Earth’s climate in much greater ecological detail than ever before.
Berkeley Lab researchers have discovered a means by which the removal of carbon dioxide (CO2) from coal-fired power plants might one day be done far more efficiently and at far lower costs than today. By appending a diamine molecule to the sponge-like solid materials known as metal-organic-frameworks (MOFs), the researchers were able to more than triple the CO2-scrubbing capacity of the MOFs, while significantly reducing parasitic energy.
Scientists have observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface for the first time. The researchers, led by Berkeley Lab scientists, measured atmospheric carbon dioxide’s increasing capacity to absorb thermal radiation emitted from the Earth’s surface over an eleven-year period at two locations in North America. They attributed this upward trend to rising CO2 levels from fossil fuel emissions.
Reducing greenhouse gas emissions (GHG), which result from the burning of fossil fuels, also reduces the incidence of health problems from particulate matter in these emissions, according to Berkeley Lab researchers and colleagues. They calculated that the economic benefit of reduced health impacts from GHG reduction strategies in the U.S. range between $6 and $14 billion annually in 2020, depending on how the reductions are accomplished.
Today’s climate models probably overestimate the amount of carbon that will be released from soil into the atmosphere as global temperatures rise. The findings are from a new computer model that explores the feedbacks between soil carbon and climate change. It is the first such model to include a realistic representation of microbial interactions.
On Nov. 11, U.S. President Barack Obama and Chinese President Xi Jinping made a historic U.S.-China Joint Announcement on Climate Change outlining each country’s commitment to strengthen bilateral cooperation on climate change and to announce post-2020 actions in support of the effort to transition to low-carbon economies. Regarding China’s announced target of peaking of carbon
