From Wildfires to Ice Melts by City-Tech blogger Mariano Huaman

Climate change is concerning scientists especially because heatwaves are hitting the Artics, parts of Australia and United States. Recently the high-temperature spike caused by climate change has induced wildfires in Sidney and Oklahoma. Last week the extreme weather caused a grass fire in Oklahoma, which forced the authorities to ask residents to leave their houses so they can be safe.

According to the National Snow and Ice Data Center, the North Pole has lost an area of ice equal to the size of Wyoming in the recent years. An animation of the decreasing Artic Ice Melt can be seen here. The National Oceanic and Atmospheric Administration is warning that if the extreme warming continues the Antartic region could experience a climatic shift. This will not only affect the North Pole, it might affect the overall ecosystem.

High Temps in the Artic, Poles by City-Tech Blogger Saul Colon

Both the North Pole and the South Pole have been seeing record high temperatures and winter heat waves since the 1970s. And more research of the unusual weather happening in both the Arctic and the North Pole is showing that sea ice levels are at the record lows since its previous records in 1997. The warm air from these winter heat waves is not only melting the sea ice but also the density of the ice is decreasing. Although the rise of sea level is helping absorb the heat from the summer which also helps the growth of the ice pack, but with such short seasons the time for ice growth is not long enough to reproduce the ice loss during the summer. The North Pole seems to be doing worse than the Arctic showing record high temperature of 30°F above normal winter temperatures. With this strange phenomenon and strange weather patterns researchers are doing more to try to understand how global warming and the decline of sea ice is affecting our planet.

The Connection between Global Warming and Heavy Floods by City-Tech Blogger Henry Ovalle

One of the reasons why we’re getting more heavy rains and more devastating floods these past decades in the United States is because the air temperature has been getting warmer. As the air gets warmer it holds more moisture, and when it meets with cool air it causes heavier precipitation. An example of the same principle can be observed when we boil water: the moisture condenses into very small drops of liquid floating in the air and when the drops get bigger, they precipitate.

According to the article, historically large storms that used to occur every 20 years in the Midwest and Northeast will be expected to occur every 4 to 6 years by the end of the 21st century. The article featured a video by Dr. Amanda Staudt, a climate scientist for the National Wildlife Federation. I have to admit that I agree 100% with Dr. Amanda Staudt because records show that these events have already become more frequent over time.

Making Sea Level Rise Work For Us? by City- Tech Blogger Dave

The article that I choose to discuss is an article about a report from NOAA The National Oceanic and Atmospheric Association. In the article it says that in the coming decades the coastlines of the United States will be reduced due to sea level rise. They came up with six scenarios of sea level rise that ranged from low severity to high severity so that the federal government can plan accordingly.  Scientists predict that the sea level will rise by about 1 foot on the low end but could rise up to 8 feet. If the sea were to rise 8 feet, it would have huge consequences as about six million Americans would lose their homes. Scientists believe that the growing sea level rise is due to the melting of the arctic ice due to global warming. In the last five years scientists have increased their predictions on how much the sea level will rise by the end of the century.

My opinion on this is that I find it hard to believe that the sea level will rise by that much by the end of the century. I feel we should find a way to use the sea water in places in the country that are in need of water. I feel that we need to find a way to filter the salt out of the water and treat it so that it can be used for everyday life. Since the ocean makes up so much of the earth, we need to find a way to use the water. There are many parts of the country that are surrounded by water but there seems to be no way to make good use of it. A good example of this is California which has the Pacific Ocean bordering it on the west and they have an incredible problem with getting enough freshwater and are often times are experiencing a drought. If we find a way to make the salt water usable in everyday life by refining it to make it usable, I feel we can counteract sea level rise.

Coastal Cities Could Flood Three Times a Week by 2045 by City-Tech Blogger Keng Wai Lam

In the recently released article “Coastal Cities Could Flood Three Times a Week by 2045,” John Upton, the author, says that floods could occur several times a week on average by 2045 along the mid-Atlantic coastline, where seas have been rising faster than nearly anywhere else, and where lands are sagging under the weight of geological changes. New York City, one of the major coastline cities, has always encountered floods during hurricanes, storms, or even gusty winds. I remembered that New York City was paralyzed by Hurricane Sandy, the subway was flooded, my aunts’ house was totally  flooded, and there were long lasting power outages which made half of Manhattan loose power. As we saw from Hurricane Sandy, disastrous floods claimed people’s lives and their property. You could imagine what would happen if New York City is flooded three times a week.

The flooding would generally cluster around the new and full moons,” said Erika Spanger-Siegfried, a Union of Concerned Scientists analyst who helped produce the new study. “Many tide cycles in a row would bring flooding, this would peter out, and would then be followed by a string of tides without flooding.”

Seas have recently been rising worldwide by an average of about an inch a decade, a rate of change that’s accelerating as global warming expands oceans and causes ice to melt. The East Coast endured sea level rise at more than twice the global rate from 2002 to 2014.
