Comments Off on Archaeologist suggests ancient humans helped catalyze the Sahara’s desertification

The Sahara Desert we know, with its rolling sand dunes and hot temperatures, used to be a verdant grassland with lakes. Scientists have traditionally attributed the dramatic change to a wobble in Earth’s orbital axis , but now archaeologist David K. Wright of Seoul National University is suggesting actually, humans may have been to blame. A 10,000-year or so wet period called the African Humid Period brought moisture to northern and eastern Africa. But around 8,000 years ago the moisture balance began to change. Today below the sand-dominated landscape can be found signs of rivers and plants, remnants of a greener history. In an article published in the journal Frontiers in Earth Science , Wright explained humans used to be thought of as passive agents in the end of the African Humid Period. But he thinks humans might actually have been active agents in the change. Related: The Mediterranean will become a desert unless global warming is limited to 1.5°C Wright said, “In East Asia there are long established theories of how Neolithic populations changed the landscape so profoundly that monsoons sopped penetrating so far inland.” He thinks a similar phenomenon could have happened in the Sahara. People growing crops and raising livestock could have changed the environment , exposing soil, and sunlight bouncing from the soil could have warmed the air, influencing atmospheric conditions enough so there wasn’t as much rainfall, which only added to the desertification of the Sahara. As yet, Wright needs more evidence for other scientists to fully get on board with his ideas. He said, “There were lakes everywhere in the Sahara at this time, and they will have the records of the changing vegetation. We need to drill down into these former lake beds to get the vegetation records, look at the archaeology , and see what people were doing there.” If Wright turns out to be right, his research could yield insights into how we can adapt to large scale climate change .

Trump team claims funding climate change is "a waste of your money"

Comments Off on Trump team claims funding climate change is "a waste of your money"

Predictions that the environment wouldn’t fare well under Donald Trump are already coming true. His budget proposal aims to slash Environmental Protection Agency (EPA) funding by 31 percent, tossing out climate change programs because as White House budget director Mick Mulvaney said, those are “a waste of your money.” Perhaps Trump’s America First budget proposal shouldn’t come as a surprise: it’s highly militaristic and hard on the arts, the sick, the poor, foreign aid, and of course climate change. Under the Trump budget, pollution cleanup efforts and energy efficiency measures would be shoved to the side. Related: Trump to purge climate change from federal government Over 50 EPA programs could be lost under the Trump budget, including large-scale cleanup efforts for the Chesapeake Bay and Great Lakes and assistance for Alaskan villages hurting because of climate change. States would be left to pick up the pieces. And so much for Trump’s blustering about jobs – around one in five EPA workers would lose theirs under the so-called America First budget. Mulvaney hearkened back to campaign trail language when he said, “This comes back to the president’s business person view of government , which is if you took over this as a CEO, and you look at this on a spreadsheet and go, ‘Why do we have all of these facilities, why do we have seven when we can do the same job with three, won’t that save money,’ and the answer is yes…You can’t drain the swamp and leave all the people in it. So, I guess the first place that comes to mind will be the Environmental Protection Agency.” He also doubled down on Trump’s view of climate change. “We’re not spending money on that anymore,” Mulvaney said. “We consider that to be a waste of your money.” Ultimately Trump’s budget is simply a recommendation; Congress will write and pass a budget. It remains to be seen if they’ll gut the EPA as much as Trump wishes. Via The Guardian Images via Gage Skidmore on Flickr and Eric Vance/USEPA Environmental-Protection-Agency on Flickr

Allan Savory Explains How Livestock Can Help Fight Desertification and Reverse Climate Change in this Riveting TED Talk

Comments Off on Allan Savory Explains How Livestock Can Help Fight Desertification and Reverse Climate Change in this Riveting TED Talk

We know now that an excess of 350 parts per billion (ppb) of CO2 in the atmosphere will cause increasingly catastrophic weather events in the future. We are now at almost 400 ppb. There is a very small window of opportunity—about 3 to 5 years—to bring that level back to 350 ppb. What if there existed a concept, new to popular thinking, but tested over a period of fifty years and proven successful, that would solve the problem of CO2 sequestration , reverse desertification, and provide as a side benefit many other social and economic improvements? Watch this riveting TED Talk  featuring biologist and environmentalist Allan Savory , who explains how herding livestock can help save our lands.
