studies and investigations pertaining to climate science in the most general sense
A central figure in the controversy over human-caused climate change has been “The Hockey Stick,” a simple, easy-to-understand graph my colleagues and I constructed to depict changes in Earth’s temperature back to 1000 AD. The graph was featured in the high-profile “Summary for Policy Makers” of the 2001 report of the Intergovernmental Panel on Climate Change (IPCC), and it quickly became an icon in the debate over human-caused (“anthropogenic”) climate change.
The Yale Climate and Energy Institute will host a panel discussion on how global warming will affect New England in the 21st century and how the region is preparing for the coming changes. The meeting will take place at the Yale School of Forestry & Environmental Studies, in Burke Auditorium of Kroon Hall, on 195 Prospect Street in New Haven and include short talks by climate and infrastructure experts and a panel discussion with Senator Chris Murphy.
Join us for a discussion of these topics with panelists:
– Senator Chris Murphy (D, CT)
Radley Horton from Columbia University Earth Institute will speak on climate projections for New York City. The $20 billion Special Initiative for Rebuilding and Resiliency (SIRR) Plan for New York is grounded upon climate risk information provided by the New York City Panel on Climate Change (NPCC). This expert panel, tasked with advising the City on climate-related issues, completed a ‘rapid response’ climate assessment with updated climate projections.
Cameron Wake is a research associate professor in climatology at the Institute for the Study of Earth, Oceans and Space at the University of New Hampshire. He also has a joint appointment in the UNH Department of Earth Sciences and is the Josephine A. Lamprey Fellow in Climate and Sustainability at the UNH Sustainability Institute.
How will global warming affect New England in the 21st century and how is the region preparing for the coming changes? On September 13th Yale Climate & Energy Institute hosted a town hall meeting on these questions, featuring short talks by climate and infrastructure experts and a panel discussion with Senator Chris Murphy (D, CT).
The increase in anthropogenic atmospheric carbon dioxide (CO2) alters the atmosphere-ocean equilibrium, changes seawater carbonate chemistry and lowers ocean pH. Ocean acidification is a predictable consequence of rising atmospheric CO2, and lower seawater pH and calcium carbonate (CaCO3) saturation in surface waters have significant implications for the marine organisms.
Global warming simulations suggest that wet regions (where precipitation exceeds evaporation) will become wetter and dry regions drier by the end of the 21st century (e.g., Held and Soden 2006), with larger contrasts expected between dry and wet seasons (Chou et al., 2013). This ‘rich-get-richer’ behavior is consistent with a large increase in the moisture content of atmosphere, leading to enhanced horizontal moisture fluxes across regions.
(CNN) Most of us can appreciate that the world is an ancient place and that a lot has changed in the almost 4.6 billion years since it took its shape.
It’s not easy to have a feel for the amount of time that has passed, but grappling with deep time helps you understand why an atmospheric carbon dioxide concentration (CO2) of 400 parts per million (ppm) is meaningful.
Deep time is geologic time and the scale needed to fathom the evolution of life, mountains, oceans, and Earth’s climate.
Subpolar ocean gyres (large systems of rotating ocean currents) in the Southern Hemisphere are found poleward of the Antarctic Circumpolar Current near the Weddell and Ross Sea. They play a key role in the global energy and water budgets. These gyres are crucial for the transport of heat around the planet, as well as the distribution of nutrients and marine species. Thus, the subpolar gyres are important in the mixing and transformation of water masses.
