Changes in sea level could be more significant than ever before

Due to the accelerated melting ice in Greenland and Antarctica, researchers believe that worldwide sea levels could increase much more than anticipated. 

On 2013, the Intergovernmental Panel on Climate Change reported that, global waters would rise by between 52cm and 98cm by 2100. However, a new study confirms that changes in the global temperatures could cause the sea levels to double or triple that amount.  

The IPCC report in 2013 only considered a 17-83% of the possibilities of sea level rising, where areas, this new study covers 5-95% estimates—which means this study looks at a broader range of results, according to BBC news. 

Researchers believe that if there are no significant reductions in emissions, we would see global waters rising between 62cm and 238cm by 2100. According to these studies, the earth could lose an equivalent area of land to 1.79 million square kilometers—approximately the size of Libya.

 If this becomes a reality, this could have severe implications to the planet, and hundreds of millions of people could be displaced. Many of the affected areas would be major cities such as London, New York, and Shanghai as well as large swathes of Bangladesh, where it will be nearly impossible for people to live in. 

Researchers remain hopeful and believe that there is still time to prevent these scenarios from occuring. The governments around the world must take action to inform the people and bring awareness to the rising levels of emissions. 

Climate change and wild spring weather

By-in-large, spring weather has been arriving earlier each year in the United States. For instance, the frost-free season was 10 days longer between 1991 and 2011 than it was from 1901 to 1960.

This may come as a shock to Midwesterners, who saw several inches of snow fall this Sunday, April 15th. So what’s going on?

Among some other factors, the Greenland Block has a lot to do with the snowy spring of 2018, according to Dr. David Mechem of the University of Kansas. Mechem, a professor of geography and atmospheric science, explained that there is a persistent atmospheric area of high pressure above Greenland which funnels cold air from the poles straight into the mid-latitudes of North America. He told KCUR that the block was in place throughout February and March and is finally starting to break down, which would bring long-awaited warmer temperatures to the midwest.

Further research is needed to establish exactly what kind of effect climate change has on spring weather, but scientists are noticing some changes. Winter storms (even if they happen in April) have increased in frequency and intensity in the Northern hemisphere since 1950 according to the National Climate Assessment. Nor’easter winter storms plague the eastern U.S. and are caused by the the cold air from the Arctic and warm air from the Atlantic interplaying. This year, that region of the U.S. saw several Nor’easters in very quick succession, which is unusual. A recent study in the journal Nature Communications found that as the Arctic’s climate continues to warm at an alarming rate, winter storms becoming more likely in the eastern U.S.

The good news is that as the Greenland block continues to break down, residents of the mid-latitudes can expect spring to finally arrive. The bad news is that unpredictable spring weather can be expected to continue coming years as the climate continues to change.
