Creepy at the EPA

In June of 2009, a story surfaced about the alleged suppression by the US EPA of information related to climate change. The source of the information was reported to be one Dr. Alan Carlin, who, although a real EPA analyst, was in fact, an economist, not a scientist. Distortions of the story, from the usual…

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…

Last Time Carbon Dioxide Levels Were This High: 15 Million Years Ago

By analyzing the chemistry of bubbles of ancient air trapped in Antarctic ice, scientists have been able to determine the composition of Earth’s atmosphere going back as far as 800,000 years, and they have developed a good understanding of how carbon dioxide levels have varied in the atmosphere since that time. But there has been…

Catastrophic sea levels ‘distinct possibility’ this century

A breakthrough study of fluctuations in sea levels the last time Earth was between ice ages, as it is now, shows that oceans rose some three meters in only decades due to collapsing ice sheets. The findings suggest that such an scenario — which would redraw coastlines worldwide and unleash colossal human misery — is…

The stakes are high for us and our children. Everyone should take part in the effort, and HOME has been conceived…

Earth 2100

How will world look at 2100?To change our future, first we must imagine it… It’s an idea that most of us would rather not think about — that within the next century, life as we know it could come to an end. Our civilization could crumble, leaving only traces of modern human existence behind. It…
