The Incredible Track Record of Early Climate Models

Thirty years ago, NASA scientist James Hansen testified to Congress that the age of climate change had arrived.

Is THIS Graph the only one needed to act on Global Warming?

Studies point to cognitive impairments at carbon dioxide levels believed possible by the end of this century, additional observation informed models tend to project higher warming scenarios, further research points to the possibility of self-reinforcing feedbacks in the climate system – again affecting the outcome of current unmitigated releases of heat-trapping gases to Earth’s atmosphere.…

How Alfred Hitchcock’s The Birds was inspired by Red Tide Algae Bloom

In this 2015 talk, David Reay from the University of Edinburgh talks about Nitrogen and Red Tides, and explains how it inspired Alfred Hitchcock’s 1963 The Birds film.

CO2 May Make Earth +10-15ºC Hotter, Like Early Paleogene

A new study led by scientists at the University of Bristol has warned that unless we mitigate current levels of carbon dioxide emissions, Western Europe and New Zealand could revert to the hot tropical climate of the early Paleogene period – 56-48 million years ago. https://www.bristol.ac.uk/news/2018/july/co2-levels-paleogene-period.html Read The Atlantic article here: They were strange days…

The 5 Big Climate Unknowns

Climate unknowns include the rate of sea level rise, ozone loss, how the Gulf Stream will react and what it possibly means, the Earth’s response, and the potential for extra methane release from methane clathrates, stored at continental margins. There are many more climate unknowns, for example elaborated in this article https://thinkprogress.org/what-are-the-unknown-unknowns-of-global-warming-1438d934bdee Climate Change Interview…

In Just 10-15 Years World May Hit 2 Degrees of Warming

Back in 2011, a Cornell University research team first made the groundbreaking discovery that leaking methane from the shale gas fracking boom could make burning fracked gas worse for the climate than coal. https://www.desmogblog.com/2018/04/11/climate-change-two-degree-warming-fracking-natural-gas-rush-ingraffea Why a half-degree temperature rise is a big deal https://climate.nasa.gov/news/2458/why-a-half-degree-temperature-rise-is-a-big-deal Paris 1.5-2°C target far from safe, say world-leading scientists http://www.climatecodered.org/2017/07/paris-15-2c-target-far-from-safe-say.html Transcript…

Thousands of little Volcano like Hills form in Arctic!
