A U.S. Carbon Cycle Science Plan by Anna M Michalak, Robert B Jackson, Gregg Marland

By Anna M Michalak, Robert B Jackson, Gregg Marland

Realizing of the Earth’s carbon cycle is an pressing societal desire in addition to a difficult highbrow challenge. The affects of human-caused adjustments at the international carbon cycle can be felt for hundreds and hundreds to millions of years. Direct observations of carbon shares and flows, process-based knowing, facts synthesis, and cautious modeling are had to be sure how the carbon cycle is being transformed, what the implications are of those transformations, and the way most sensible to mitigate and adapt to alterations within the carbon cycle and weather. the significance of the carbon cycle is accentuated through its advanced interaction with different geochemical cycles (such as nitrogen and water), its serious function in financial and different human structures, and the worldwide scale of its interactions.

This goal aims to understand interlinked natural and managed systems sufficiently for individuals, corporations, and governments to make rational and well-informed decisions on how best to manage the global carbon cycle, and especially the anthropogenic impacts on this cycle. 1 Motivation 1127 1128 1129 1130 The global carbon cycle is complex and closely linked to the energy, water, and nutrient cycles on Earth and to demographic and economic systems globally. Efforts to manage the carbon cycle will have broad environmental and economic impacts.

Once those vulnerabilities are clearer, we can test management possibilities and evaluate effectiveness in reducing vulnerability and altering the global carbon budget, including the resources needed for achieving these management goals. 5 Related Issues 991 992 993 994 995 996 997 Vulnerability in terrestrial carbon pools and fluxes is directly related to physical changes in ecosystems and climate, including changes in water resources, energy, food supply, resource extraction, and livelihoods.

Many potential decisions have both positive and negative consequences, and scientists need to provide a comprehensive, quantitative analysis of the trade-offs of greenhouse gas emissions, other environmental impacts, economic and social impacts, and the distribution of costs and benefits. 3 Major uncertainties 1156 1157 1158 1159 1160 1161 1162 1163 1164 1165 1166 1167 1168 1169 1170 Low carbon futures will impact both environmental and economic systems, and we are just beginning to understand the range and magnitude of the issues.
