150TH
The Met isn’t the only New York City institution celebrating an anniversary in 2020 - 2021.
130TH
April 2021 marks the 130th year of Carnegie Hall, the prestigious landmark that has delighted audiences with performers from around the world, including Frank Sinatra, the Beatles and Gustav Mahler.
125TH
Another NYC mainstay with a recent anniversary is the New York Public Library. Established in 1895, the main branch in midtown Manhattan, with its entrance famously flanked by lion statues named Patience and Fortitude, is a must-visit landmark that turned 125 in May 2020.
90TH
Almost a hundred years ago, competing skyscrapers shot into the atmosphere in a race to become the world's tallest building. At 1 ,046 feet, the Chrysler Building — which celebrated its 90th anniversary in May 2020 - was the first to hold the title, but only briefly.
90 TH
One year after the Chrysler Building was built, the Empire State Building was completed, topping off at 1,250 feet (or 1,454 if you count the antennae and spire) and remained the world's tallest building for a respectable 40 years. The iconic skyscraper — synonymous with the Big Apple itself — turns 90 in May 2021.

7 . “Snow algae（藻类）is already a part of summer on the Antarctic Peninsula. A warming planet may mean a lot more of it. The algal blooms（藻华）that blanket parts of Antarctica’s snow cover in the summer are likely to expand as the planet warms.” researchers say in a new study.
“Green snow algae is found in warmer areas along the coastline where summer temperatures are above freezing. but still cold enough for there to be snow.” say scientists in a study published Wednesday in the journal Nature. It’s also more abundant in areas in close proximity to nesting sites and gathering places for animals like penguins and seals, whose feces（粪便）fuel the algae’s growth.
Green algae isn't new for Antarctica—it’s known to have been there to some degree for decades. New Scientist notes. But what researchers found suggests that climate change could have a major impact on algae in Antarctica, which in turn, could have its own impact on a warming planet.
The scientists don't predict that green algae will spread on all part, of the penguin. In fact. some small low-lying islands are likely to lose algae, because those islands may lose their summer snow cover altogether-and the snow algae can't grow without snow. But they predict the amount of green algae is likely to grow on larger pieces of land, where it can spread upward to higher ground that still has snow.
So what does more algae mean, besides turning the landscape green? It’s not totally clear. The green algae works as a carbon sink—the current amount of algae in Antarctica pulls about 500 tons of carbon from the atmosphere each year. On the other hand, algae also makes the surface of the snow darker, which leads to less sunlight being reflected from the snow's surface. Scientific American notes. That means that more of the sun's heat gets absorbed, speeding up wanning. It's high time that we should protect our planet.
