You know the old problem of how to portray the round globe of Earth on a flat map? Now a trio of map experts has worked together to solve this problem. Their new map is 2-sided and round.
by Andrew Glikson Warnings by leading climate scientists regarding the high sensitivity of the atmosphere in response to abrupt compositional changes, such as near-doubling of greenhouse gas concentrations, are now manifest: According to Wallace Broecker, (the “father” of climate science)…
(University of Copenhagen – Faculty of Science) Unpredictable, abrupt changes to Earth’s system of ocean currents could commence from rate-induced tipping, model study shows. ‘The findings point to fundamental limitations inclimate predictability,’ authors warn.
One billion years of Earth’s geological movements have been summarized in a 40-second video, in which the continents and oceans flit about like amorous butterflies while demonstrating just how mobile the surface of the Earth actually is. The history of plate tectonics, the slipping and sliding around of the Earth’s crust and the continents, has […]

Researchers at the SETI Institute say that unusual dark streaks on sun-facing slopes on Mars, debated about for years, may be small landslides caused by a combination of salts and melting ice just below the surface.
(NASA/Goddard Space Flight Center) A short-lived resurgence in the emission of ozone depleting pollutants in eastern China will not significantly delay the recovery of Earth’s protective ‘sunscreen’ layer, according to new research published Feb. 10 in Nature.
(University of Sydney) Iceberg melt is responsible for about half the fresh water entering the ocean from the Antarctic and Greenland ice sheets. Accurately modelling how it enters is important for understanding potential impact on ocean circulation.
For the Central and Eastern United States, this has been a particularly brutal winter. Fargo, North Dakota has seen sub-zero temperatures since February 5, The Washington Post reported, while New York City has gotten hit with around 22 inches of…
The industrialised former colonisers are facing economic competition from the former colonies. The latest in a long series of global movements demands reduction of carbon emissions. This happens to target nations with coal-fired economies and poor people with wood-fired cooking….
by Andrew Glikson Intergovernmental Panel on Climate Change (IPCC) reports and comprehensive summaries of the peer-reviewed literature raise questions regarding the assumptions inherent in computer modelling of future climate changes, including the supposed linearity of future global temperature trends (Figure…
