Scientific American: Trump Mexican Border Wall will be a “Climate Mistake”

Guest essay by Eric Worrall Scientific American thinks construction of President Trump’s border wall will dangerously exacerbate climate change. Trump’s Wall Could Cause Serious Environmental Damage The effects of building a massive concrete wall range from increased emissions to blocked wildlife migration routes. … And climate activists say that President Trump’s border wall with Mexico…

Microscopic pictures of individual foraminifers. Left: A foraminifer with a shell containing four chambers of which one is empty. Also note the spines. Right: Picture of the interior of a foraminifer. The green colour is caused by seawater with an indicator showing that the acidity has changed. The actual size of the foraminifer is about 0.25 millimeter. CREDIT Dr. Lennart de Nooijer (NIOZ)

Inconvenient result: Ocean acidification can also promote shell formation

From the “non-news in the MSM because it doesn’t support the cause” department comes this inconvenient study from the NIOZ ROYAL NETHERLANDS INSTITUTE FOR SEA RESEARCH. Unexpected result: Ocean acidification can also promote shell formation Proton pumping accompanies calcification in foraminifera Fact: More carbon dioxide (CO2) in the air also acidifies the oceans. It seemed to…

The Southern Hemisphere has a higher capacity to grow sea ice than the Northern Hemisphere, where continents block growth. New research shows that the expansion of Southern Hemisphere sea ice during certain periods in Earth's orbital cycles can control the pace of the planet's ice ages.

100,000 year ice age cycle linked to orbital periods and sea ice

From BROWN UNIVERSITY Earth’s orbital variations and sea ice synch glacial periods PROVIDENCE, R.I. [Brown University] — Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet’s higher latitudes. For the past million years, these glacial-interglacial cycles have repeated roughly on a…
