Researchers Detail Role of Localized Climate Change in Ancient Depopulation of Southwest Colorado

Washington State University researchers have detailed the role of localized climate change in one of the great mysteries of North American archaeology: the depopulation of southwest Colorado by ancestral Pueblo people in the late 1200s.

New Research Reveals Rise in Temperature of Seawater Around Antarctica

The temperature of the seawater around Antarctica is rising according to new research from the University of East Anglia.

Increase in Greenhouse Gases will have an Important Impact on Future Climate in Africa

New research demonstrates for the first time that an increase in greenhouse gas concentrations thousands of years ago was a key factor in causing substantially more rainfall in two major regions of Africa. The finding provides new evidence that the current increase in greenhouse gases will have an important impact on Africa’s future climate.

Extreme Weather Events May Increase Greenhouse Gas Emissions

Scientists at Helmholtz Zentrum München, in collaboration with colleagues from the TU München and the Karlsruhe Institute of Technology (KIT), have studied how soil microorganisms react to climatic change. Their result: Extreme weather events such as long periods of drought and heavy rainfall have a strong impact on the metabolic activity of microbes. This may lead to a change in the nutrient balance in soils and, in extreme cases, may even increase greenhouse gas emissions like nitrous oxide to the atmosphere concentrations.

Logging Triggers Gradual Release of Carbon Stored in Forest's Mineral Soils

Logging doesn't immediately jettison carbon stored in a forest's mineral soils into the atmosphere but triggers a gradual release that may contribute to climate change over decades, a Dartmouth College study finds.

Critical Ozone ‘Feedback’ Factor Could Be Missing in Calculations of Future Global Warming

Many of the complex computer models which are used to predict climate change could be missing an important ozone 'feedback' factor in their calculations of future global warming, according to new research led by the University of Cambridge and published today (1 December) in the journal Nature Climate Change.

Climate Change Buffers against Protection Measures for the Baltic Sea

Despite extensive measures to protect the Baltic Sea from anthropogenic activities since the late 1980s, oxygen concentrations continue to decrease. Rising temperatures in the bottom water layers could be the reason for the oxygen decline. This paper reports on the first comprehensive analysis of measurement data from the Boknis Eck time series station, and it was recently published in the international journal Biogeosciences.

Study Reveals Historic Emergence of Ice in the Arctic Ocean

“We have not seen an ice free period in the Arctic Ocean for 2,6 million years. However, we may see it in our lifetime.” says marine geologist Jochen Knies. In an international collaborative project, Knies has studied the historic emergence of the ice in the Arctic Ocean. The results are published in Nature Communications.

NEIKER-Tecnalia Evaluates Impact of Climate Change on Soil Microbial Communities, Ecological Processes

The Basque Institute for Agricultural Research and Development NEIKER-Tecnalia has had a Microbial Observatory in the Ordesa and Monte Perdido National Nature Reserve (Huesca Pyrenees) since 2011.

Climate Change Significantly Affects Today’s Microscopic Ocean Organisms

A study of ancient marine algae, led by the University of Southampton, has found that climate change affected their growth and skeleton structure, which has potential significance for today’s equivalent microscopic organisms that play an important role in the world’s oceans.
