Rivers of the Sea: Global Ocean Survey Studies #GEOSECS (1975)

Film about GEOSECS, the Geochemical Ocean Sections Study, a global survey of the three-dimensional distribution of chemical, isotopic and radiochemical tracers in the ocean. George Veronis of Yale University speaks about models for ocean layers and circulation in the world ocean, and data gathering by R.V. Melville (SIO) and R.V. Knorr (WHOI). Extensive footage onboard…

James Lovelock speaks Planetary Stewardship 1991

For a historical perspective on climate progress, James Lovelock talked at The University of Kansas, addressing our responsibility in light of global warming, almost 3 decades ago in 1991.

Scientist explains Global Warming in 1990

Climate scientist Stephen Schneider talks climate change. Dr. Stephen Schneider is one of the most notable and outspoken scientists on the topic of climate change. His moderate and scientific approach to explaining climate change has helped congressmen, journalists, and citizens understand the complex, and often contradictory, issues related to global warming. In this ever timely…

Ice Core Secrets Could Reveal Answers to Global Warming

At the Stable Isotope Lab in Boulder, Colo., scientists are doing a lot of the same things that those CSI folks do on TV. But instead of being “crime scene investigators,” these experts are more like “cold scene investigators.” Geoscientists like lab director Jim White work primarily with one raw material : ancient ice, in…

On the Influence of Carbonic Acid in the Air Upon the Temperature of the Ground

In 1896, Svante Arrhenius published below study on the greenhouse effect, the required carbon dioxide gas concentrations for change, and temperature variations deriving from mean, and processes in the climate system which draw down CO2, and the effects of CO2 on the climate on geological times, and elaborated on possible timescales of climate change. Arrhenius estimated based on the CO2 levels at…

NASA: Four Decades of Sea Ice From Space

NASA: One of the most visible signs of climate change in recent years was not even visible at all until a few decades ago. The sea ice cap that covers the Arctic Ocean has been changing dramatically, especially in the last 15 years. Its ice is thinner and more vulnerable – and at its summer minimum…

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…

2013 was the second-hottest year without an El Niño since before 1850

The Guardian: According to the global surface temperate data set compiled by Kevin Cowtan and Robert Way, which achieves the best coverage of the rapidly-warming Arctic by filling in data gaps between temperature stations using a statistical method called kriging, 2013 was the 5th-hottest year on record (since 1850). The top three hottest years (2010, 2005,…
