Algae

Newsweek spoke with hikers who were planning to skip a section of the Pacific Crest Trail because of drinking water possibly contaminated with an algal bloom.

Exposure to toxic algae can cause a range of symptoms, including rashes, stomach problems, neurological issues, and death.

Scientists say the algae has "tumbleweed-like" growth and smothers entire reefs.

Climate change may make such algal blooms more common, triggering more melting in a feedback loop.

Researchers found that while glyphosate "resistance" was seen in some ponds, it came at a cost.

The unusual red coloring can cause snow to melt faster.

The researchers argue that green seaweeds like these are the descendants of all land plants that exist today.

Scientists hope the remains will offer new clues about the emergence of photosynthesising green plants.

Not only does the reddish snow have a similar color to watermelon, but it also exhibits a somewhat sweet smell which partially resembles that of the real fruit.

The red tide algae has caused beach closures in Palm Beach County.

The looming hurricanes could exacerbate the red tide by increasing nutrient loads in coastal waters.

The red tide poses health risks to both marine wildlife and human beings.

High levels of red tide algae were found 10 miles off of the shore of Pinellas County this week, officials said.

The brown tide could be a potential new food source for the red tide.

Working without payment to decrease their sentences, inmates in Florida regularly participate in public works projects.

150 tons of dead fish have been collected in Manatee County over the last two weeks.

Eighty percent of all fish in Münster's Aasee lake have already died.

Most sources of drinking water in the U.S. are vulnerable to contamination from toxic forms of algae, and climate change might be increasing the risk.

"It smells like death."

Two thirds of the coral reef—designated a world heritage site—have been damaged, according to aerial surveys.

Scientists warn it may be too late to save the Great Barrier Reef, which experienced the worst dying off of coral ever recorded in 2016.

Some have been classified animals or flowers, but these creatures aren't so easy to pin down.

The effect hasn't been included in global climate models.
