Ice Age Maps showing the extent of the ice sheets. Back to Don's Maps The last great ice age began around 120 000 years ago.

Ice Age Maps showing the extent of the ice sheets

One massive ice sheet, more than 3 kilometres thick in places, grew in fits and starts until it covered almost all of Canada and stretched down as far as Manhattan. Then, 20 000 years ago, a great thaw began. Over the following 10 000 years, the average global temperature rose by 3.5° C and most of the ice melted. Rising seas swallowed up low-lying areas such as the English Channel and North Sea, forcing our ancestors to abandon many settlements.

The Earth Has Lungs. Watch Them Breathe. – Phenomena: Curiously Krulwich. House Republicans seek to open up national forests to mining and logging. Congress is to consider two bills that would allow states to hand over vast tracts of federal land for mining, logging or other commercial activities – just weeks after the arrest of an armed militia that took over a wildlife refuge in Oregon in protest at federal oversight of public land.

House Republicans seek to open up national forests to mining and logging

The legislation, which will be presented to the House committee on natural resources on Thursday, would loosen federal authority over parts of the 600m acres (240m hectares), nearly one-third of the land mass of the US, it administers. 01 orp cascadia. Congressman doubles down, accuses NOAA scientists of doctoring results. On Monday, we covered a series of requests (culminating in a subpoena) from Texas Congressman Lamar Smith (R).

He sent the requests to the National Oceanic and Atmospheric Administration (NOAA), demanding data and communications relating to a recent update of NOAA’s global surface temperature dataset. The NOAA provided Rep. Global Warming and Climate Change skepticism examined. We’re Running out of Water. Nasa-water-aquifers.

Study: The Gulf Stream system may already be weakening. That's not good. In the 2004 disaster film The Day After Tomorrow, climate change causes a major disruption of ocean currents in the Atlantic Ocean, which in turn brings about a sudden ice age in New York City.

Study: The Gulf Stream system may already be weakening. That's not good.

That scenario was ridiculous and overwrought. Still, the underlying idea that global warming could mess with some important ocean circulation systems actually isn't that far-fetched. Such an event wouldn't blanket Manhattan in ice, but it could wreak havoc on fisheries or speed up sea-level rise in cities like Boston and New York. Schematic of the major warm (red to yellow) and cold (blue to purple) water pathways in the North Atlantic subpolar gyre.

(Woods Hole Oceanographic Institute) In particular, scientists have been paying close attention to the Atlantic Meridional Overturning Circulation (AMOC), an ocean pattern that transports warm water from the tropics to the North Atlantic. The study suggests the slowdown has arrived sooner than expected. The melting of Antarctica was already really bad. It just got worse. A satellite view of Antarctica is seen in this undated NASA handout photo obtained by Reuters on Feb. 6, 2012.

(NASA handout via Reuters) Students launch desktop recycler that turns pop bottles into 3D printer plastic. Three engineering physics students at the University of British Columbia have developed a desktop plastic recycler and extruder that turns plastic waste into the material needed for 3D printing.

Called ProtoCycler, the machine can grind plastic, such as pop bottles and Lego, and melt it into a filament that can be fed into 3D printers. Bad news: Brazil is losing huge chunks of Amazon rainforest again. Brazil's battle against deforestation was one of the biggest environmental success stories of the last decade.

Bad news: Brazil is losing huge chunks of Amazon rainforest again

Between 2005 and 2012, the amount of Amazon rainforest cut down each year fell by 70 percent: (Nepstad et al, 2014) But the good news didn't last. Deforestation in the Brazilian Amazon started ticking up again in 2013. Interaction of ocean oscillations caused 'false pause' in global warming. UNIVERSITY PARK, Pa.-- The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate system.

They do not signal any slowdown in human-caused global warming. "We know that it is important to distinguish between human-caused and natural climate variability so we can assess the impact of human-caused climate change on a variety of phenomena including drought and weather extremes," said Michael Mann, Distinguished Professor of Meteorology, Penn State. "The North Atlantic and North Pacific oceans appear to be drivers of substantial natural, internal climate variability on timescales of decades.

"So I ask the chair," — referring to Sen. Bill Cassidy (R-LA) — "Do you know what this is? Leading Climate Denier and Harvard Scientist Took $1.2 Million Bribe From Oil Companies. Wei-Hock Soon, an aerospace engineer and a part-time employee at the Harvard-Smithsonian Center for Astrophysics is one of the few respected scientists who spoke against the general consensus that human activity is a significant contributor to climate change.

He has published 11 papers on climate change since 2008. However, it was recently shown that he received $1.2 million from oil companies in exchange for his “science”. According to leaked documents, the papers were simply “deliverables” that he completed in exchange for their money. He used the same term to describe a testimony he prepared for Congress. Science against money.

A Brief History of Ice Ages and Warming Causes of Global Climate Change Playing with Numbers A Matter of Opinion Unraveling the Earth's Temperature Record Stopping Climate Change A Brief History of Ice Ages and Warming Global warming started long before the "Industrial Revolution" and the invention of the internal combustion engine. Global warming began 18,000 years ago as the earth started warming its way out of the Pleistocene Ice Age-- a time when much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice.

Earth's climate and the biosphere have been in constant flux, dominated by ice ages and glaciers for the past several million years. UN says CO2 pollution levels at annual record high - Science. GENEVA — Carbon dioxide levels in the atmosphere reached a record high in 2013 as increasing levels of man-made pollution transform the planet, the UN weather agency said Tuesday. The heat-trapping gas blamed for the largest share of global warming rose to worldwide concentrations of 396 parts per million last year, the biggest year-to-year change in three decades, the World Meteorological Organization said in an annual report.

Researchers show Earth's magnetic reversal occurs faster than previously thought. A study by researchers from UC Berkeley, Columbia University, Italy and France shows that the most recent reversal of Earth’s magnetic field occurred in fewer than 100 years, which is much more rapidly than previously believed. Courtney Sprain, campus graduate student, and Paul Renne, director of the Berkeley Geochronology Center and a campus earth and planetary sciences professor, worked with overseas researchers to study the magnetic properties of sediments in Italy.
