Thick Arctic Sea Ice Near Greenland Has Broken Up for the First Time in History

The sea off Greenland's northern coast has long been referred to as "the last ice area.” The ice there is so old and thick that scientists believed the shelf would be the last to remain intact in the area in the face of climate change. Now, a new development is challenging that assumption: As The Guardian reports, the strongest sea ice in the Arctic has started to break apart for the first time in recorded history.

The ice above Greenland owed its fortitude up to this point to the Transpolar Drift Stream. Ice from Siberia carried by the current collects on Greenland's coast, condensing to create a sturdy ice pack that's more than 13 feet thick, with ridges exceeding 65 feet in some places. The ice has remained whole at least since scientists started keeping satellite records of it in the 1970s, but an unusually warm and windy year has compromised its integrity.

The breaking sea ice has been documented twice this year—once in February and once in August, both times when temperatures spiked above the averages for the region. The heatwaves weakened the ice and dislodged it from the coast, and warm winds pushed it further from land, creating a patch of open water larger than has ever before been observed in the Arctic. Temperatures will eventually drop back down and the gap will close up, but that won't be enough to reverse the damage. The ice has already been displaced to a spot where it will melt more easily the next time warm weather arrives up north.

Climate scientists are rethinking how global warming might reshape the Arctic. Now that "the last ice area" has started to break up, experts are now saying the true last holdout of the region may be further west. Norwegian Meteorological Institute scientist Thomas Lavergne described the phenomenon as "scary" on Twitter.

Less permanent sea ice means polar bears will have fewer areas for hunting marine mammals, their main food source. New gaps in the ice can also trigger a feedback loop: While white ice reflects the Sun's heat, the dark ocean surface absorbs it, raising temperatures and causing ice to melt faster, feeding a perilous cycle. Arctic ice cover at both poles has been shrinking at a rapid rate in recent decades, with the Larsen C breaking off from Antarctica last summer and forming an iceberg the size of Delaware. Scientists predict that there will be no summer ice present in the Arctic Ocean at all starting some time in the next 10 to 30 years.

These Nature Posters Show the Most Endangered Animal in Each State

The U.S. has more than 1300 endangered or threatened species, from South Dakota's black-footed ferret to Colorado's Uncompahgre fritillary butterfly to the blue whales that live off the coast of Alaska. These wild animals could disappear if prompt wildlife conservation measures aren't taken, and people are largely to blame. Globally, human activities are the direct cause of 99 percent of threatened animal classifications, according to the Center for Biological Diversity.

Some of these animals may even be in your backyard. A research team commissioned by NetCredit used data from the U.S. Fish and Wildlife Service to highlight the most endangered animal in each state. For this project, "most endangered" refers to the animals that face the greatest risk of extinction. An art director and designer then teamed up to create gorgeous illustrations of each animal.

Since some regions are home to many of the same creatures, a different animal was selected from the shortlist of endangered species in cases where there were duplicates from one state to the next. The goal was to cast light on as many threatened species as possible, including the ones that rarely make headlines.

"We hope this will start a conversation around the fact that it's not just the iconic species we see on nature documentaries that we're at risk of losing forever," the research team said in a statement.

Take the black-footed ferret, for instance. It's the only ferret that's native to North America, but its ranks have dwindled as its main food source—prairie dogs—becomes harder to find. Prairie dog eradication programs and loss of the ferret's habitat (due to farming) are some of the factors to blame. A ferret breeding colony was established in the past, but only 200 to 300 of the animals still remain, rendering them critically endangered.

The West Coast Is Preparing for Another Super Bloom

In spring of 2017, people flocked to Southern California's deserts to see fields of wildflowers brightening the normally sparse terrain. That level of vegetation, also known as a super bloom, is an event that only occurs after winters of heavier-than-average precipitation. Now just two years later, the rare sight is about to return to California's Anza-Borrego desert, the Los Angeles Times reports.

The 2018/2019 winter season was an unusually wet one for California. Between October 1 and the beginning of February, Downtown Los Angeles saw 12.91 inches of rain, which is approximately 167 percent more than the seasonal average. All that precipitation will produce an explosion of color when spring arrives in Anza-Borrego desert three hours southeast of Los Angeles. Experts predict the 2019 super bloom could start as early as late February and last through March.

If the last super bloom is any indication, this year's event will attract crowds of sight-seers. Anywhere from 250,000 to 500,000 people visited the desert to look at and snap pictures of the flowers in 2017. Many local communities were overwhelmed by the influx of tourists, but this time around they know what to expect. Portable toilets will be set up around popular sites, and thousands of maps of showing where the flower fields, gas stations, and toilets are located are ready to be passed out to drivers.

Visitors also have a few things to learn from the past super bloom. Two years ago, foot traffic in places like the Antelope Valley California Poppy Reserve was so heavy that trails had to be closed down to protect delicate flowers from selfie-taking tourists.
