Many people still think that global warming is just a myth, but unfortunately it isn’t. The simplest definition of global warming, as it says, the globe is warming up. The temperatures all over the world increase and the poles are melting down, making the sea level to rise. Since 2000, NASA recorded the hottest 16 years from the last 134 years. Also, not everybody knows the symptoms of global warming, or what effects it has on the planet, some symptoms being the change in climate, the glaciers and ice shafts melting down, the coral reef dying, and the excess of greenhouse gasses in the atmosphere.
1. Temperature increase
The first sign is the temperature increase all over the world. Added to those 16 hottest years mentioned above, the first six months of 2016 each set a record worldwide for the warmest months since 1880. Those months also set the record for the warmest half year, with an average of 1.38 degrees Celsius warmed than the late 1800’s.
2. Larsen C
The second sign is the melting glaciers. Larsen C is the fourth largest ice shelf in Antarctica. Larsen C has a crack in the rift, which NASA is monitoring since 2014. Right now, the crack is 100 miles long and some places two miles wide. But the worst part is only 20 miles away from reaching the other end of the ice shaft. Since in January 2017 it did 17 miles, it’s more likely to break the following months. The glaciers, which are large sheets of ice and snow are melted due to the temperature increase. The rate of melting is speeding up, taking much less for the glaciers to melt compared with 50 years ago. If Larsen c ice shaft brakes, if will highly affect the rate of melting of those glaciers.
3. Dying coral reefs
The third sign is the death of coral reefs. One role of the oceans is to balance Earth’s level of CO2 that is in the atmosphere. If there is more CO2 in the atmosphere, the oceans will absorb more CO2, which will increase the acidity of the oceans. An increased level in acidity will make it harder for corals to build, corals being the home of millions of sea creatures.
4. Climate Change
The forth sign is the climate change. Because the globe is warming up, the climate and the seasons are changing also. The most obvious example is the increase in temperatures. The IPCC (Intergovernmental Panel on Climate Change) predicts that by the end of this century, the temperatures will be from 2.5 to 10 degrees Fahrenheit higher. Another example is the increase the frost-free season, which is the season in which plants and grains are growing. This season increased eight weeks, and it can affect the ecosystems and the agriculture.
5. Greenhouse Gasses
The fifth sign is the Greenhouse Gasses in the atmosphere. Greenhouse gasses (GHG) are gasses that trap heat and emit radiation. The natural greenhouse gasses let heat escape more easily into space, and block a part of the radiations emitted by the sun. On the other hand, the man-made greenhouse gasses keep the heat in the atmosphere and the sun radiation penetrate more easily the ozone layer, and this also affects the climate change and the breakdown of the glaciers.
Humans gave the Earth a disease and now is slowly dying, but it can still be saved. Using the public transportation instead of the personal car, building more solar panels, and recycling are some examples how we can save the planet. It is not to late, but we must act fast!
