Experts: Arctic craters could be ‘Visible Effect’ of Global Warming

The preliminary results from scientists studying the mysterious holes (craters), that began emerging in recent times in Siberia, indicate that climate change may be a cause. The Russian crater research team led by Alexei Plekhanov of the Scientific Centre of Arctic Studies, explained a possible mechanism, in a Nature interview. The past two summers were…

Novel climate proxy reveals CO2 content of Earth’s atmosphere, of the past 400 million years

The study New constraints on atmospheric CO2 concentration for the Phanerozoic (DOI: 10.1002/2014GL060457), by Peter J. Franks, Dana L. Royer, David J. Beerling , Peter K. Van de Water, David J. Cantrill, Margaret M. Barbour, and Joseph A. Berry, estimates CO2 in Earth history based on a new climate proxy. Estimates are in particular based…

Everything you need to know about Mass Extinction, Sea Level Rise and Amplification

Professor Peter Ward (Professor, Sprigg Institute of Geobiology, The University of Adelaide) explains the interconnections of rising carbon dioxide levels and flood basalt, and how it leads to anoxic oceans (with Hydrogen sulfide). Ward explains how today’s CO2 levels will result in sea level rise with disrupting implications for crops and how deglaciation will ultimately…

Tropospheric Ozone in the Anthropocene: Are We Creating a Toxic Atmosphere?

Published on Feb 19, 2014: Jack Fishman explains how elevated ozone levels damage plants, affecting crop yields. Factors among ozone levels include, precipitation and temperature. Further studies found that yields present a consistent function depending on the ozone concentrations. Laboratory simulations suggest that the findings of the yield decline are a trend, which is projected…

IPCC Climate Change Report The Five Key Points

The Guardian recently summarized the five keypoints of the new IPCC AR5 Impact Report. The world faces threat to food supply, conflicts over water rights and growing inequality. The only option to is cut emissions By Suzanne Goldenberg (The Guardian): 1. Food threat Climate change is already taking a sizeable chunk out of global food supply…

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…

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…

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…

Mass Extinction: Let’s Not

Notice: The original video is no longer available. Published on Sep 28, 2013: “Last Hours” is the first in a series of short films that explore the perils of climate change and the solutions to avert climate disaster. Each subsequent film will highlight fact-based challenges facing the human race, and offer solutions to ameliorate these…

Abrupt Climate Change In The Arctic (And Beyond) An Update

AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…

Rebound an Earth Story


Glacial isostatic adjustment, why we have glacial and interglacial periods, how we can reconstruct climate history, and how the Earth is responding to the retreat of the continental glaciers.

Earth Energy Imbalance

James Hansen explains Earth energy imbalance from anthropogenic forcing and the urgency to act, because of the climate inertia. Earth’s Energy Imbalance By James Hansen, Makiko Sato, Pushker Kharecha and Karina von Schuckmann — January 2012   Deployment of an international array of Argo floats, measuring ocean heat content to a depth of 2000 m,…
