Global
warming has consistently been happening and affecting our planet. Amanda
MacMillan answers the basic questions asked about global warming by sharing her
knowledge on the subject. Global warming is when the temperature of the earth
keeps increasing at alarming rates. In the past 50 years the average global
temperature increased at the fastest rate recorded in history. If we do not try
and improving the situation now the average temperature will increase about ten
degrees Fahrenheit over the upcoming century. Global warming happens when
carbon dioxide, other pollutants, and greenhouse gasses collect in the
atmosphere and absorb light and radiation that bounces off earth’s surface.
Usually the radiation would be left in space but the pollutants (that can last
for years to centuries) trap heat and that is what causes the planet to get
hotter (aka the greenhouse effect). The United States is one of the biggest contributors
of global warming by burning fossil fuels that create electricity. The biggest
contributor is coal-burning power plants. Scientists believe that earths
increasing temperatures are what causing the longer and hotter heat waves,
droughts, heavier rainbow, and dangerous hurricanes. The planet’s oceans
temperatures are also getting higher which can cause storms to get more
dangerous. Because of global warming a category 3 storms can become a category
4 storms, which are more dangerous. Scientists have noticed an increase in
hurricanes since the 1980s. The rising temperatures have caused water sources
to melt and droughts to get worse. The sea levels are rising and creating
coastal flooding. America is in second place in “biggest polluting country”
right after China. We need to stop polluting our planet and start protecting
it.
