Wow! Alaska is hotter than new york. That's why.

The sultry temperature recorded yesterday (July 4th) means that this usually snow-covered city is only 370 miles (595 kilometers) from the Arctic Circle, which is hotter than new york. According to the time and date, new york City reached 85 degrees Fahrenheit yesterday. )

What caused the sultry weather in Alaska? A high-pressure system called "thermal dome" by the Meteorological Organization of the capital has stopped over this area. The weather forecast says that by July 8, the temperature in Alaska will be higher than normal. From a broader perspective, the temperature in Alaska is above average, partly because of the decrease of Arctic sea ice and the warming of the ocean there, Rick Toman, a climate expert at the Alaska Center for Climate Assessment and Policy, told AFP in March this year. At that time, Alaska was experiencing a record high temperature for two months.

According to Life Science, the impact of climate change on the Arctic is disproportionate, and the Arctic is warming twice as fast as other parts of the earth. This is because there is a positive feedback cycle: sea ice and snow reflect a lot of solar radiation back to the atmosphere. However, as more reflective surfaces melt, exposing darker water below, more heat is trapped in the water instead of bouncing back into space, making it hotter … and causing more melting and warming.
