Fun fact: Overlooked effect of melting ice caps โ„๏ธโ„๏ธ๐Ÿฅถ๐Ÿฅถ
Antarctica and the Arctic doesn't just house thousands of unique species. The two continent also plays a crucial role in conditioning the temperature of the Earth, and managing climate in most part of the world. Yet a lot of this consequences is overlooked and left to worsen by the years.๐ŸŒก๏ธ๐Ÿ”ฅ Ice caps melting decrease the overall efficiency of the albedo effect on the Earth. Firstly, we need to know what is the albedo effect, the term measure a surface's reflectivity, describing how much sunlight it bounces back into space versus absorbing it as heat. Ice and snow have a very high albedo because of its color white and reflective quality. For thousands of year, Antarctica and the Arctic have played a crucial role in reducing the temperature of the Earth. In todays time, the reduction in area of these continent have significantly reduce it's albedo, increasing the temperature of our planet and melting more ice caps, this is called a positive feedback loop (A system where the output or result of a process amplifies the original input, causing a chain reaction that escalates the effect).โ˜€๏ธ๐ŸŒ To understand the second affect of ice caps melting, it is essential to understand the role of ocean movement and circulation. Ocean movement can be separate into 2 parts, the surface level and the deep water level. The movement in the surface level is generated by wind and pulling the water layer beneath it, combining with the Earth rotation, this forms circular motion at the surface. Regarding the deep water region the thermohaline circulation is the vertical movement of the deep ocean power by the difference in density of water and temperature. The ocean water in the two poles is significantly colder and more salty, the density differences pushes it down and replace by warmer water at the bottom, this convection like current forces microorganism to move up and down the ocean level, feeding species and forming the basis for thousands of food chain. As we all know, the majority of ice caps is consist of fresh water, when these ice melts, its deposit huge amount of water with lower density than saline water from the ocean. Overtime, this will disrupt the thermohaline circulation, damaging marines life. ๐Ÿฌ๐Ÿ

๐ŸŒค๏ธ Howโ€™s The Weather Been Lately??
[Fact #1 maybe] everyoneโ€™s posting knowledge so here comes wisdom: (TL;DR: alarmingly terrible please wear a mask.) Long answer: You might be aware that Hanoi has repeatedly topped the worldโ€™s leaderboard of the most polluted city lately. Not only do the widespread usage of petrol and diesel-powered vehicles emit carbon dioxide, the combustion of the fuels at such high temperatures is also apparently enough to, in a sense, โ€œburnโ€ the air! The overwhelming abundance of nitrogen and oxygen in our atmosphere means when these molecules splitโ€ฆ Nโ‰กN + O=O โ†’ N=O + N=O โ€ฆ they path the way for a cascade of reactions: O=O + N=O โ†’ O + O=N=O O + O=O โ†’ O-O=O (ozone but bad) O=N + O=O + N=O โ†’ O=N=O + O=N=O NO2 + CH3C(O)OO โ†’ CH3C(O)OONO2 (or โ€œPANโ€) These gases cast the familiar brown haze seen throughout the day, and some of them in particular, are classified a 4 on the โ€œfire diamond,โ€ which means โ€œVery short exposure could cause death or major residual injury.โ€ โ€ฆ which is extremely concerning government you gotta do somethingggg stay safe ppl!!! (Ms. Louise did not make me post this btw)

SAT trick question
Rui has: 2 machines, 1 robot, and a star. Is this sentence grammatically correct? I mean yeah??? It looks ok, no major mistakes or anythingโ€ฆ WRONG๐Ÿ‘ฟโŒโŒโŒ๐Ÿ™… An ENGLISH colon (not bio๐Ÿ˜’) has to appear behind a FULL sentence, so technically the example up there is wrong. SATโ€™s usually tricks you by using these questions so be careful everyone Stay safe and sane o(๏ฝ€ฯ‰ยด )o
