This week Leah Birch will be leading discussion on Lenaerts et al. 2013: "Irreversible mass loss of Canadian Arctic Archipelago glaciers". Leah says the following about the paper:
"The ice volume in the Canadian Arctic Archipelago is the third largest in the world, and in the past decade that area has been warm and dry, very unfavorable for glaciers. The authors model the present day climate in this area using a regional climate model and confirm it matches observations. They then use this model to predict future melt in this region, finding less Read more about ClimaTea Journal Club
Sea ice is a thin, dynamic interface between the atmosphere and ocean. We review the role of sea ice in the climate system, and discuss how we model sea ice in large-scale climate models. The growth of sea ice is a largely one-dimensional, thermodynamic process that involves the transport of heat and salt within the sea ice. Sea ice is a permeable medium, and Read more about Special ClimaTea Lecture
Abstract: The ocean is the primary reservoir of thermal energy in the earth system. As greenhouse gasses affect the planetary energy balance, key ways to track and predict energy variability are ocean observations and modeling. However, to go beyond rough trend estimates, there are major challenges in observation, understanding, modeling, and prediction to be overcome. This Read more about ClimaTea Lecture
"The remote impacts of climate feedbacks on regional climate predictability"
This week Cristi Proistosescu will be leading discussion on Roe et al. 2015 (papers attached): The remote impacts of climate feedbacks on regional climate predictability. Cristi says the following about the paper:
"In this paper the author use a a moist energy balance model in conjunction with locally defined feedbacks to asses the relationship between uncertainties in feedback patterns and uncertainties in temperature response patterns. They find that uncertainties in Read more about ClimaTea Journal Club
This week GS Chris Horvat will be leading discussion on Rahmstorf et al (2015), 'Exceptional twentieth-century slowdown in Atlantic Ocean overturning circulation.' Chris says the following about the the upcoming ClimaTea:
The ocean plays a key role in the industrial-era climate system: it has taken up nearly a third of the anthropogenic carbon and over 90% of the energy trapped by elevated greenhouse gas concentrations. The ocean circulation sequesters heat and carbon to depth and thereby regulates the exchange with the atmosphere at the sea surface. It has recently been recognized that energetic submesoscale fronts (1–10 km wide) may make a leading- Read more about Special ClimaTea Lecture: "Submesoscale turbulence in the upper ocean"
This week Katie Dagon will be presenting Williams et al. (2015) "Contribution of anthropogenic warming to California drought during 2012–2014." (attached) Katie says about the paper:
"The ongoing California drought is a much-discussed topic both in the news and recent scientific literature (1). Of particular interest is whether the drought has been influenced by climate change. To that end, I will lead a discussion exploring the causes of the California drought and its connection to anthropogenic climate change. The anthropogenic signature on the drought is discussed in Williams et Read more about ClimaTea Journal Club: Contribution of anthropogenic warming to California drought
