2 . Verkhoyansk, a town in northeastern Siberia, about 6 miles within the Arctic Circle, recorded a temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) on June 20. 2020, likely setting a new record for the hottest temperature recorded that far north.

The new record comes as Siberia—and the Asian continent as a whole—have experienced unusually warm conditions since the start of this year. The whole region has been off-the-charts warm lately. And while it’s difficult to know the impact of climate change on individual records or temperatures in any given season, experts say the developments are part of a broader warming trend that has been documented across the globe.

The sudden movement of heat is being caused by high-pressure ridge (脊)of air—sometimes called “heat dome (穹)” that is blanketing the area. When this happens, air gets squeezed into one location and sinks, pushing warm temperatures down to the surface.

The high-pressure ridge also prevents clouds from forming, so sunshine comes through without being weakened by clouds. North of the Arctic Circle when that temperature was observed, they had 24 hours of daylight, so they were receiving solar energy for those entire 24 hours.

The town of Verkhoyansk is known for having the biggest extremes between winter and summer than any other city in the world, with their average high temperature minus 47 degrees Fahrenheit in winter In June and July, their average temperature is close to 70 degrees. In their climate history, they’ve been above 90 degrees over 150 times, and above 95 degrees at least dozen times.

“Since the start of the year, we’ve been noticing that Asia— particularly northern Asia, like Russia—has been extremely warm,” —said Ahira Sanchez-Lugo, a climatologist at the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information. Forecasts suggest that this part of Siberia could see at least another week of above-average temperatures before things stabilize. But conditions in Asia have been warmer than usual for most of 2020.

C．It moves fast and carries heat away.

D．It presses heat down and keeps solar energy down on the earth.

3. What can we learn from the text?

A．Verkhoyansk is the hottest town in the world.

B．The largest extremes in Verkhoyansk are more than 95 degrees.

C．Northern Asia takes the lead in global warming.

D．The average high temperature in Verkhoyansk is minus 47 degrees Fahrenheit.

3 . As people are becoming more socially conscious about where their food comes from and how it impacts the planet, they are choosing animal-free plant-based options. Cow-free meat has been around for quite some time and the popularity of brands like Beyond Meat and cultivated meat from Aleph Farms and other are soaring. While there are a large number of plant-based milk substitutes, none of have the same taste of cow’ milk. Now, an Israeli food-tech startup Remilk created real dairy products without harming a single cow or the planet.

The company stresses that their product Remilk is not a milk substitute but rather is the real deal. Made from a special process called microbial fermentation, milk is manufactured in a lab instead of in a cow. And the end product is very healthy. “In a very simple way, we take the gene that encodes for the milk protein,” said Aviv Wolf, CEO of Remilk. “The gene function as an instruction book for the production of the protein it encodes. And so, we insert the gene into a microbe that we’ve developed and it instructs our microbe to produce the specific protein in a very efficient way.”

The company says that the lab-produced milk tastes identical to the real thing and they hope to eventually replace cows by creating every dairy product sold. They expect to roll out plant-based cheese and yogurt in addition to milk. “Remilk was founded with the mission to stop using animal to produce our food because, as dairy lovers, we realize that giving up on milk is not an option,” Wolff said. “But today’s milk comes with an unreasonable price tag. The dairy industry is destructive to our planet, our health, and our animals, and is simply not sustainable any more.”

The environmental price tag of dairy farming is way too high. According to the World Wildlife Fund, dairy cows add a huge amount of greenhouse gasses to the atmosphere and contribute to global warming and climate change as well as foul the air around them. Dairy operation consume large amounts of water and run-off of manure and fertilizers from there farms get into local waterways. The production of Remilk uses only 5 percent of the resources and produces only 1 percent of the waste of producing cow’s milk according to company. And they accomplish this by being 100 percent cruelty-free dairy farms.
