Natural Gas versus Coal Power Plants: Greenhouse gas warming

Ken Caldeira: We had a paper come out comparing effects of natural gas versus coal plants, aimed at understanding how much methane leakage there could be from natural gas before it caused more near-term warming than coal. The answer depends on how efficient the different power plants are, but one thing that is clear is…

ScienceCasts: The Cloudy Future of Arctic Sea Ice

As climate change continues to hammer Arctic sea ice, pushing back its summertime boundaries to record-high latitudes, NASA is flying an innovative airborne mission to find out how these developments will affect worldwide weather. NASA: Oct 15, 2014: Climate change is a global phenomenon, yet Earth scientists are keeping a wary eye on one place…

Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity

Climate State interviewed Bill McGuire, Emeritus Professor of Earth Sciences at the University College London, one of Britain’s leading volcanologists and contributing author to the 2011 IPCC report. He called for an early tsunami warning system (2004, The Guardian) and warned in his book The Waking Giant, of the Earth response (more earthquakes, tsunamis and…

What Is Biochar Gardening?

Expert tree care Tallahassee gardening services. CBS – MINNEAPOLIS (WCCO) — The mayor of Minneapolis and the chairman of the Shakopee Mdewakanton Sioux signed an agreement Tuesday that promotes the use of biochar.Jim Doten, Minneapolis’ environmental services’ supervisor, says it’s a product similar to cooking charcoal that’s used for gardening.“They really increase the soil fertility,…

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…

Rapid sea-ice loss may increase the rate of Arctic land warming by 3.5 times – affecting permafrost

Recently a mysterious Siberian crater has been discovered, which subsequently raised questions about the circumstances surrounding the crater formation.  Theories include Pingo formation and connections to the thawing of permafrost (ClimateState reported). Robert Scribbler, summed it up: One theory on the feature is that it might be a pingo — a melting of a permafrost water pocket…

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…
