Comments Off on Wildfires in Siberia are emitting enough carbon to harm the entire planet

Wildfires are raging in Russia and Siberia , and they could have drastic consequences for the entire planet. Blazes burning in the Amur region since the start of 2018 have damaged an area around six times bigger than during the same time period in 2017, according to Greenpeace — and they have released nearly twice the annual carbon emissions of Moscow in a single month. This spring, dry, warm conditions in Siberia have readied the area for wildfires, according to Earther — and in May, the fires have picked up in a big way. Local farmers sometimes light fires in Siberia to replenish soil nutrients or clear land, but winds can cause the fires to blaze out of control.

And these out-of-control fires aren’t just bad news for locals, but for people all over the Earth: experts estimate that the Amur fire has released around 110 megatons of carbon dioxide . According to Greenpeace, “Each wildfire heats up the planet. At the scale we’re seeing in Amur, that’s a large amount of CO2, and a major setback in efforts to meet Paris Climate Agreement goals.” Soot from the wildfires also doesn’t bode well for the planet. Wind can carry black carbon to Arctic ice and snow, impairing their reflective properties, which “increases the amount of solar radiation absorbed by the surface” and “accelerates the melting of snow and ice,” Greenpeace said. Humans are responsible for as much as 90 percent of wildfires — but this means they can also prevent them, by taking steps like completely extinguishing cigarettes or bonfires and never leaving fires unattended.

Florida coral reefs plagued with mysterious disease

Comments Off on Florida coral reefs plagued with mysterious disease

With coral reefs under threat worldwide, researchers in Florida are racing to understand and treat a mysterious disease that threatens to decimate the third-largest coral reef on Earth. Over the past four years, the as-yet unidentified, potentially bacterial disease has already had a significant impact on Florida’s coral species, half of which are fatally vulnerable to the disease. “When they’re affected by this, the tissue sloughs off the skeleton,” Erinn Muller, science director at Mote Marine Lab’s Center for Coral Reef Research and Restoration in the Florida Keys, explained to NPR . “And we see that once a coral is infected, it usually kills the entire coral, sometimes within weeks. And it doesn’t seem to stop.” After being hired by the State of Florida to study the health of coral reefs near Miami , scientist William Precht first observed the disease moving from coral to coral, with particularly devastating effects on star and brain coral. “This is essentially equivalent to a local extinction , an ecological extirpation of these species locally,” Precht told NPR . “And when you go out and swim on the reefs of Miami-Dade County today, it would be a very rare chance encounter that you’d see some of these three or four species.” Related: Scientists made a liquid ‘umbrella’ to protect coral reefs from sun damage Researchers at Mote Marine Lab are hard at work to determine how to protect coral from the mysterious disease . “Anything from… looking at chlorine-laced epoxy as an antiseptic, and even looking at how antibiotics interact with the disease,” Muller said. “Because if it is bacterial, then antibiotics would be a way to stop it.” Mote Marine Lab is also serving as a nursery for baby coral, which are released into the wild when they are ready. At this moment, the reefs under siege will need all the help they can get. “We’re really at a critical juncture right now, where we have corals left on the reef,” said Muller. “Before we lose more corals, now is the time to start making a change.” Via NPR Images via  NOAA National Ocean Service   (1)
