Probing New Frontiers of Climate
Environmental scientists at Brookhaven Lab are investigating how various factors affect Earth’s climate by probing the fundamental building blocks of the climate system. These include aerosols—tiny particles suspended in Earth’s atmosphere that seed the formation of clouds—as well as the plant physiological structures that sustain entire ecosystems from the Arctic to the tropics. Our data will improve the models used to predict long-term global climate change and the daily atmospheric conditions that impact renewable energy efficiency and demand.
Aerosols, clouds, and climate: Clearing the uncertainty—and the air
Brookhaven Lab’s atmospheric scientists are addressing one of the greatest sources of uncertainty in models that predict Earth’s future climate: aerosols and the clouds that form when water condenses on these tiny airborne particles. Brookhaven’s climate researchers are working on a set of innovations for measuring and modeling aerosol and cloud properties and their motions in space and time to better understand their impacts and improve planning for mitigating the environmental and human impacts of climate change. This fundamental atmospheric science also has relevance for air quality and human health, and for improving weather forecasts, so that communities on the ground can be better prepared.

Plants as indicators and mitigators of climate change
Land plants play an important role in determining the rate of global change. About one-third of our annual carbon dioxide emissions are taken up and stored by plants, subsidizing our use of fossil fuels, but the future of this subsidy is uncertain. Brookhaven researchers are working to improve understanding of fundamental plant processes and how they are represented in climate models by investigating the capacity of plants to take up carbon dioxide in globally important and climate sensitive biomes. In combination with carbon capture and storage, plants offer one of the few proven ways to efficiently remove large quantities of carbon dioxide from our atmosphere.
