A recent study published in Global and Planetary Change demonstrates cost-saving opportunities in the otherwise computationally expensive process of high-resolution climate modeling. General Circulation Models (GCMs, occasionally also referred to as ‘global climate models’) are extremely useful tools used to understand how our climate system works. The models use mathematical equations to describe the physics of the oceans and atmosphere. These equations quantify, for example, how hot air tends to rise (the reason hot air balloons fly) and how the wind flows from high-pressure areas to l
formerly “Climate Science” this has been updated in recognition of the fact that ALL of our articles, events, etc. involve climate sciience. ”Climate change” is intended to suggest changing elements of the climate: e.g., shifts in global oceanic and atmospheric circulation and ensuing changes to temperature, precipitation, groundwater levels, saltwater intrusion.
Human-induced climate change is altering precipitation patterns in most parts of the world (Stocker et al., 2013). In the future, climate change will likely exacerbate droughts (Trenberth et al., 2014; Dai, 2012) and drastically increase the likelihood of floods throughout many parts of South America, Africa and southern Asia (Hirabayashi et al., 2013) …
Many species of plants and animals have declined in abundance and distribution or become extinct because of anthropogenic changes to the environment. Mangroves, trees that form dense coastal forests in tropical and subtropical areas, have declined in areal coverage by approximately one third since 1950 largely because of coastal development and logging.
Sea level rise along the eastern mid-Atlantic coast of the U.S. is approximately 2 times greater than the average global rate. Sustained regional sea level rise has implications for coastal communities, increasing the risk of flooding and the local effect of storm surge. Professor Tal Ezer …
Last month the USDA announced plans to create seven climate change “hubs” to provide outreach and training on behalf of the farm, agriculture and forestry sectors in the seven regions they serve. The effort represents a realignment of existing government resources rather than new investment. It’s a welcome development, and a model for other government agencies to collectively address climate change-related impacts outside the realm of agriculture.
Antarctic krill are the keystone species in the Antarctic ecosystem, directly transferring energy in the form of carbon from algae to top predators. Ocean circulation is an important contributor in structuring and maintaining the circumpolar and the regional distribution of Antarctic..
A headline-making article by Sherwood, et al. in the January issue of Nature ascribes the wide spread in climate sensitivities reported by global circulation models (GCMs) to how they account for atmospheric convective mixing, a process that controls cloud formation in the lower troposphere…
Community ecology seeks to untangle structural patterns and underlying biological mechanisms across time and space. Though developed for studies above ground, community ecology provides an equally relevant framework for looking at the below ground world, a realm that’s now understood to store and cycle most of Earth’s organic carbon.
Yale Professor Ron Smith speaks on Climate Change in New England at a A Town Hall Meeting, entitled, “Climate Change in New England: What’s Next?” which explores how global warming will affect New England in the 21st century and how the region is preparing for the coming changes.
