10,853 out of 10,855 scientists agree: Global warming is happening, and humans are to blame

Virtually all of the scientific papers published in 2013 accept climate change By Lindsay Abrams (Salon): As geochemist James Lawrence Powell continues to prove, the only people still debating whether or not climate change is “real,” and caused by human activity, are the ones who aren’t doing the actual research. In an update to his ongoing project…

Spot on! Michael Mann: The irreversible impacts from Climate Change

Mike Mann discusses his new piece in Scientific American, which outlines critical thresholds in climate warming in the not-too-far-off future, based on the sensitivity of Earth climate. Scientific American: Most scientists concur that two degrees C of warming above the temperature during preindustrial time would harm all sectors of civilization—food, water, health, land, national security, energy…

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…
