Climate change could suffocate life on planet Earth

EurekAlert (Release): Falling oxygen levels caused by global warming could be a greater threat to the survival of life on planet Earth than flooding, according to researchers from the University of Leicester. A study led by Sergei Petrovskii, Professor in Applied Mathematics from the University of Leicester’s Department of Mathematics, has shown that an increase in…

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…

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…

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…

Earth From Space HD 1080p / Nova


The groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet. Produced in extensive consultation with NASA scientists, NOVA takes data from earth-observing satellites and transforms it into dazzling visual sequences, each one exposing the intricate and surprising web of forces that sustains life on earth.

‘Global sunscreen’ plan could wreck tropics, study finds

by Richard Ingham | Phys.org | January 8, 2014 | Release  URL An idea by the father of the H-bomb to slow global warming by sowing the stratosphere with light-reflecting particles could wreck the weather system in the tropics, a study said Wednesday.  The scheme may benefit northern Europe and parts of Asia, but around…

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,…

Can scientists overcome huge uncertainties to pin down how close, or far, we might be to a tipping point?

A 2007 Royal Society paper by NASA scientist Drew Shindell: “… the rarity of palaeoclimate evidence for hydrate-induced climate changes argues that this is a fairly unlikely candidate for near-term sudden climate change. Unlike the others, however, anthropogenic climate change may alter the probability of hydrate release when compared with the past, making the overall…

Heat stress reduces labor capacity under climate warming

NOAA study about heat stress and projected labor impact: John P. Dunne, Ronald J. Stouffer, and Jasmin G. John. Journal: Nature Climate Change. DOI: 10.1038/nclimate1827 Key Findings Due to projected increases in temperature and water vapor in the atmosphere: Labor capacity losses related to heat stress are projected to double globally by 2050 with a warming climate. Global…

Global CH4 Atmospheric Methane Average 1811ppb(METOP-2)

Continuing the global CH4 methane average jump, on August 13, 2013 am, 0-12 hr, we hit a new high average of 1811 ppb. A comment at Arctic Sea Ice Forum notes: “Assumed methane emissions for the RCP scenarios; which clearly shows that we are now exceeding the methane emissions assumed for RCP 8.5; which is…

Newly discovered Mesospheric Polar Clouds possible indicator of Global Warming

The Aeronomy of Ice in the Mesosphere (AIM) mission is the first satellite dedicated to the study of noctilucent clouds. Noctilucent clouds, sometimes called Polar Mesospheric Clouds, were first reported in 1885. Forming at altitudes above 50 miles, they are so faint that they can only be seen from the ground in the reflected light…

NASA: Potential Evaporation in North America Through 2100 (August 2013 in HD)

Published on Aug 9, 2013 by NASA: This animation shows the projected increase in potential evaporation through the year 2100, relative to 1980, based on the combined results of multiple climate models. The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or…
