The effects of climate change are not only threatening fragile ecosystems, but could erase our past as well.

In the hot middle of August 1996, lightning struck a dense piñon-juniper range in Mesa Verde National Park, Colorado. Then flames licked up, burning northward through Soda Canyon, Little Soda Canyon, and Park Mesa’s research area. The blaze ran its course for seven days. Aircrafts doused the park in water, and fire retardants known as “slurry” were used to snub out flames in the nooks of tough-to-reach craggy topography. Slurry stains are still visible, almost 20 years later, on the impressionable sandstone trail to Spruce Tree House, a collection of cliff dwellings. The national park contains an estimated 600 buildings fashioned into cliff alcoves, and over 5,000 other archeological sites produced by the Ancestral Puebloans. Although the fire quit just before reaching the Visitors’ Center, burning through a small (but important) 4,781 acres in the end, it accelerated a natural process known as spalling. When water evaporates in sandstone, layers of rock flake off. Because of this accelerated spalling, the fire claimed an important victim—the famous Battleship Rock Panel, which was degraded and destroyed. This petroglyph panel portrayed humans and animals, dated roughly back to 1100 AD, was chiseled into the sandstone, and helped archaeologists contextualize life of the Ancestral Puebloans.


The tremendous loss of a pivotal archaeological site as a result of the fire not only substantially changed how park archaeologists treat post-fire sites, but also offered a revealing glimpse of what’s to come as the effects of climate change take hold over the next century. A 2014 report by the Union of Concerned Scientists featured Mesa Verde alongside 29 other national landmarks that are now at risk because of the effects of climate change. Researchers say climate change will make longer and hotter fire seasons, and the resultant fires could potentially devastate archaeological preserves like the one at Mesa Verde. The report notes that over the last 600 years in that region, the last 50 have been the hottest. But it’s not just Mesa Verde, or even the United States. Climate change threatens to erase archaeological sites across the world.

Examples are abundant. In Peru, the intricate designs of the 600-year-old city of Chan Chan are suffering from increased torrential downpours due to overly abundant El Nino patterns. UNESCO described the erosion as “rapid and seemingly unstoppable.” Ironically, many of the same processes that put these sites at risk also turn up new artifacts. By 2007, over half of the acres in Mesa Verde had burned since the fire, revealing 676 new sites previously hidden beneath vegetation. The same ecological complications that are turning frozen Chilean mummies into black ooze are also causing artifacts and bodies to emerge from receding glaciers.

Maria Caffrey, a paleo-climatologist and research associate at the University of Colorado, Boulder was hired by the National Parks Service (NPS) to study how climate change will affect sea-level rises and storm surges along 118 costal park sites. Many archaeological sites occur along coastlines, where humans settled near the water. “As the climate gets warmer, we’re estimating storms will get more intense,” Caffrey tells me.

Along the northwest coast of Alaska, for example, these bigger storms, along with erosion and rising tides, threaten to sweep away 1,000-year-old artifacts and sites of the first people to live in that area. One site along the Bering Sea contains a Yup’ik village frozen in thick layers of permafrost. It now faces the threat of melting, exposing the delicately preserved village to the elements—a 30-foot area at the edge of the site has already been washed into the sea. And it’s not just the ancient past that’s under threat. Jamestown, Virginia, part of Colonial National Historical Park, faces a massive threat from rising tides and rising water levels that might flood buried artifacts.

“Do we take them out and risk exposing them to the air, and potentially see more damage that way, or do we leave them in place?” Caffrey asks.

These questions—whether and how to save which sites—will become increasingly important as climate patterns shift, and archaeological sites begin to take the brunt of the climate blow. Even if we could figure out the exact impact of change for every important site, the nature of choosing what to protect—and how to do it—might be more of an engineering and economic problem than a scientific one. In 1999, the NPS decided to move the Cape Hatteras Lighthouse 1500 feet from the shoreline, at a cost of $11.8 million. “The decision to relocate the Cape Hatteras Light Station was a sound public policy decision based on the best science and engineering information available,” the NPS writes. It’s not clear how many lighthouses will fall into a rising sea, but it’s unlikely we can move every single structure, let alone every broader archaeological site, that is at risk.

“This is the legacy we’re leaving for future generations,” Caffrey said. “We’re going to have to ask the tricky questions, of what ones do we try to save, or if we don’t save any at all, or whether or not some of these things eventually become monuments to climate change. Instead of having a lighthouse you can walk up to, maybe it becomes a submerged site that you can take a snorkel tour around and learn about climate change that way.”

The Trump Administration won't be remembered for being kind to animals.

In 2018, it launched a new effort to reinstate cruel hunting practices in Alaska that had been outlawed under Obama. Hunters will be able to shoot hibernating bear cubs, murder wolf and coyote cubs while in their dens, and use dogs to hunt black bears.

Efforts to end animal cruelty by the USDA have been curtailed as well. In 2016, under the Obama Administration, the USDA issued 4,944 animal welfare citations, in two years the numbers dropped to just 1,716.

We often dismiss our dreams as nonsensical dispatches from the mind while we're deep asleep. But recent research proves that our dreams can definitely affect our waking lives.

People often dream about their significant others and studies show it actually affects how we behave towads them the next day.

"A lot of people don't pay attention to their dreams and are unaware of the impact they have on their state of mind," said Dylan Selterman, psychology lecturer at the University of Maryland, says according to The Huffington Post. "Now we have evidence that there is this association."

A controversial editorial on America's obesity epidemic and healthcare by comedian Bill Maher on his HBO show "Real Time" inspired a thoughtful, and funny, response by James Cordon. It also made for a great debate about healthcare that Americans are avoiding.

At the end of the September 6th episode of "Real Time, " Maher turned to the camera for his usual editorial and discussed how obesity is a huge part of the healthcare debate that no one is having.

"At Next Thursday's debate, one of the candidates has to say, 'The problem with our healthcare system is Americans eat shit and too much of it.' All the candidates will mention their health plans but no one will bring up the key factor: the citizens don't lift a finger to help," Maher said sternly.

There is no shortage of proposals from the, um, what's the word for it… huge, group of Democratic presidential candidates this year. But one may stand out from the pack as being not just bold but also necessary; during a CNN town hall about climate change Andrew Yang proposed a "green amendment" to the constitution.

Me Too Kit

The creator of the Me Too kit — an at home rape kit that has yet to hit the market — has come under fire as sexual assault advocates argue the kit is dangerous and misleading for women.

The kit is marketed as "the first ever at home kit for commercial use," according to the company's website. "Your experience. Your kit. Your story. Your life. Your choice. Every survivor has a story, every survivor has a voice." Customers will soon be able order one of the DIY kits in order to collect evidence "within the confines of the survivor's chosen place of safety" after an assault.

"With MeToo Kit, we are able to collect DNA samples and other tissues, which upon testing can provide the necessary time-sensitive evidence required in a court of law to identify a sexual predator's involvement with sexual assault," according to the website.
