These before-and-after photos of the catastrophic flooding that wreaked havoc in Colorado, affecting at least 1,918 square miles of the state and resulting in the likely deaths of 10 people and nearly $2 billion in property damage, offer a glimpse into the scope of devastation that this 1000-year storm brought down some Colorado communities.

HuffPost matched high-resolution satellite images of flooded areas from DigitalGlobe via Getty Images with high definition photos of those same flooded regions on Google Earth. Use the slider bar on each image to see the before and after photos of the affected region

Rainfall Redistribution Will Make Some Areas Warmer And Drier

A new study from Columbia University’s Lamont-Doherty Earth Observatory reveals that a northward shift of Earth’s wind and rain belts could make a broad swath of regions drier. The findings, published in Proceedings of the National Academy of Sciences, show that these drier regions include the Middle East, American West and Amazonia, while Monsoon Asia and equatorial Africa will become wetter as humans continue to heat the planet.

This new prediction is based on the warming that ended the last ice age around 15,000 years ago. During that warming, the North Atlantic Ocean began to churn more vigorously, melting Arctic sea ice, and setting up a temperature contrast with the southern hemisphere where sea ice was expanding around Antarctica. The tropical rain belt and mid-latitude jet stream were pushed north by the temperature gradient between the poles. This redistributed water in two bands around the planet.

The seasons will change this Sunday (Sept. 22), with the Northern Hemisphere moving into autumn and the South emerging from winter into spring.

 

 

The celestial event that marks this transition is called an "equinox," and it happens twice every year, around March 21 and Sept. 21. Just what is an equinox, and why does it occur?

Ancient Forest Thaws From Melting Glacial Tomb

 

An ancient forest has thawed from under a melting glacier in Alaska and is now exposed to the world for the first time in more than 1,000 years.

Stumps and logs have been popping out from under southern Alaska's Mendenhall Glacier — a 36.8-square-mile (95.3 square kilometers) river of ice flowing into a lake near Juneau — for nearly the past 50 years. However, just within the past year or so, researchers based at the University of Alaska Southeast in Juneau have noticed considerably more trees popping up, many in their original upright position and some still bearing roots and even a bit of bark, the Juneau Empire first reported last week.

The Afar Rift in Ethiopia is marked by enormous gashes that signal the breakup of the African continent and the beginnings of a new ocean basin, scientists think.

The fractures appear eerily similar to seafloor spreading centers, the volcanic ridges that mark the boundaries between two pieces of oceanic crust. Along the ridges, lava bubbles up and new crust is created, slowly widening the ocean basin.

Bumblebee Mount Hood: A Dozen Rare Bumblebees Found in Oregon National Forest (+Video)

Epoch Times - Zachary Stieber, 9/19/13

 


A dozen rare western bumblebees were discovered in western Oregon, around 15 years ago after the type of bee mysteriously dissipated west of the Cascade Mountains.

 

 

“In the last 15 years there have only been about 15 sightings of this bumblebee west of the Cascades,” Hatfield said in the announcement. “This discovery suggests that this species might have a chance to repopulate its range.”

Get ready for the Harvest Moon. Depending on where you live on the planet, it’s either Wednesday or Thursday of this week.  

“In traditional skylore, the Harvest Moon is the full moon closest to the autumnal equinox,” EarthSky reports, “and depending on the year, [it] can come anywhere from two weeks before to two weeks after the autumnal equinox.” For 2013, that changing of the seasons happens on September 22 — just a few days from now.
