The hottest year in the Earth's history was recorded with 0.68 degree Celsius in 2014, an extremely hot temperature which will make a sweat drip, hotter than hot but not as hot as an oven. It also marks the 38th consecutive year that the global temperature was above the average.
In the graph shown by NASA, the 10 warmest years happened in the 134-year record. All of this happened only starting in 2000. Following 2014 as the hottest year on the record was 2010 with a temperature of 0.67 degree Celsius and 2005 with 0.66 degree Celsius. This proves that Earth's temperature warms in an upward trend.
For the past 134 years, there is an increase of 1.5 degrees Fahrenheit. The increase was reported to be more than half in the past 35 years. The study also shows a pattern that the warmest years accelerate in every 37 years.
According to Union of Concerned Scientist, certain gases like carbon dioxide trap heat and serve like a nylon blanket that warms the planet. Burning fossil fuels like coal, oil and natural gas that generates electricity and power vehicles produces Carbon dioxide. As it overloads in the atmosphere, it traps heat, making Earth steadily warms up as a result.
Scientists conclusively identified that human activities are the biggest contributor of carbon dioxide in the atmosphere. Carbon dioxide in the atmosphere bears a fingerprint of chemicals from burned oil and gasses.
Many scientists believe that global warming plays a big part on climate change. This is making the weather unpredictable, hotter when it is hot, wetter when it is wet and colder when it is cold.
