GENEVA (WMO) | According to the World Meteorological Organization’s annual Greenhouse Gas Bulletin, the amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide. This injected even greater urgency into the need for concerted international action against accelerating and potentially devastating climate […]
Climate Change Research
Both the “fog of ignorance” and “glow of discovery” emphasize need for data rescue
Philip Brohan, climate scientist at the Met Office Hadley Centre, combines information from old documents, tree-rings and large computers, into a clear picture of what the weather used to be like. At the August 2014 ACRE (Atmospheric Circulation Reconstructions over the Earth) workshop, attended by IEDRO, Philip presented this particular visualization (seen below) of mean […]
Part 15: What should we expect? Future climate projections
By Luisa Cristini, PhD, University of Hawaii at Manoa Note from the editor: This is the fifteenth and last in a series of blog entries that focused on introductory topics in climate dynamics and modeling, and served to provide insight into the current understanding of the science.] Given the increasing evidence of climate change, what […]
Ocean acidification and the “short term“ marine carbon cycle
By Franziska Kersten, PhD Candidate in Marine Geology and Paleontology – Alfred Wegener Institute for Polar and Marine Research, Bremerhaven (Germany). The 2007 IPCC (Intergovernmental Panel on Climate Change) Synthesis Report discusses ocean acidification and its potential to harm marine calcifiers (e.g. corals) in the future. Yet a recent report in Science unequivocally states that parts of the […]
Part 14: How to project climate into the future: Emission scenarios
By Luisa Cristini, PhD, University of Hawaii at Manoa. [Note from the editor: This is the fourteenth in a series of blog entries that will focus on introductory topics in climate dynamics and modeling, and will serve to provide insight into the current understanding of the science.] Changes in external forcing (e.g., solar forcings, astronomical […]
Part 13: Holocene and Anthropocene
By Luisa Cristini, PhD, University of Hawaii at Manoa [Note from the editor: This is the thirteenth in a series of blog entries that will focus on introductory topics in climate dynamics and modeling, and will serve to provide insight into the current understanding of the science.] In addition to the low frequency variability of […]
Protocell Tech, Limestone and the Future of Architecture
by Bea Kylene Jumarang These days, words like protocell belong in biology laboratories. Even words like carbon cycle confuse the majority of people. Still, you may be asking, why is protocell being described in relation to architecture? In biology, and as Biology-Online puts it, a protocell is a large, ordered structure enclosed by a membrane, […]
Part 11: The Timescales of Climate Change: Internal Climate Variability
by Luisa Cristini, PhD, University of Hawaii at Manoa [Note from the editor: This is the eleventh in a series of blog entries that will focus on introductory topics in climate dynamics and modeling, and will be a great insight into the current understanding of the science.] Since the beginning of Earth’s history, climate has […]
A Study of the Good and Bad Effects of Volcanic Ash
By Pennell Paugh A study that has been conducted for the past six years by Rosenstiel School of Marine and Atmospheric Science at University of Miami is revealing a link between large dust storms on Iceland and glacial melting. While the dust is accelerating glacial melting it also is contributing important nutrients to the […]
Melting from underneath
By Torben Stichel, PhD., University of Hawaii at Manoa The ongoing debate on global climate change tends to give the impression that there is nothing new on this front. Of course, the candidates and media outlets involved in the upcoming election for the presidency of the United States will again use this topic as a political […]
