The cost of living in the Anthropocene

What are the true cost of living in the Anthropocene? Wikipedia: The Anthropocene is an informal geologic chronological term that serves to mark the evidence and extent of human activities that have had a significant global impact on the Earth‘s ecosystems. The term was coined recently by ecologist Eugene F. Stoermer and has been widely popularized by the Nobel Prize-winning atmospheric chemist, Paul Crutzen, who regards the…

The Rate of Sea-Level Rise

A new study paper out in nature (Nature Climate Change / 2014 / doi:10.1038/nclimate2159), explores why the rise of sea-level has slowed in the last decade. Unsurprisingly the slow-down coincidences with the observed climate hiatus (IPCC AR5, Ocean heat content uptake). Because  heat is distributed differently, depending on the state of ENSO (between El Nino or La Nina). Abstract: Present-day sea-level…

Climate Effects on Human Evolution

This article explores the hypothesis that key human adaptations evolved in response to environmental instability.  This idea was developed during research conducted by the Smithsonian’s Human Origins Program. Natural selection was not always a matter of ‘survival of the fittest’ but also survival of those most adaptable to changing surroundings. By the Smithonian  Background Paleoanthropologists – scientists who…

Global Warming Speeds Up Methane Emissions from Freshwater

By Tim Radford (Climate News Network): Scientists think the amount of methane emitted to the atmosphere from freshwater ecosystems will increase as the climate warms, triggering further warming. LONDON, 20 March – British scientists have identified yet another twist to the threat of global warming. Any further rises in temperature are likely to accelerate the release of methane from…

ClimateCrocks: Dr. Richard  Rood is a Veteran NASA Atmospheric Scientist, currently teaching at theUniversity of Michigan’s College of Atmopheric, Oceanic, and Space Sciences. Dr. Rood also posts regularly on Dr. Jeff Master’s Weather Underground. I sat down with Dr. Rood not long ago to talk about developments in climate science. This is a small, but significant…

Hydroxyl Radicals In Our Atmosphere – An Animated Explanation

Published on Oct 30, 2013 A simple yet effective clip explaining hydroxyl creation in the Earth’s atmosphere, what they do as “nature’s broom” and the benefit of their existence. Related Wikipedia: Hydroxyl RadicalThe hydroxyl radical is often referred to as the “detergent” of the troposphere because it reacts with many pollutants, often acting as the first step to their…

The Antarctic Half of the Global Thermohaline Circulation is Collapsing

By FishOutOfWater (DailyKos): The largest source of the coldest water in the world’s oceans ceased producing Antarctic Bottom Water in 1976. The surface water around Antarctica, which has be been freshening since the 1950’s, formed a lid of low-density water stopping the overturning process in the Weddell sea near the coast of Antarctica. The Weddell…

Volcanic Eruptions Add to Larger Impact on Climate

The recent slow down in global warming has been attributed to a number of factors, including excess heat being stored in the deep ocean and reductions of certain greenhouse gases. Now add volcanic eruptions to the mix of contributing factors. A new analysis published in Nature Geosciences on Sunday shows that a series of relatively small…
