Global Warming: Alarmism or Fact?

So here is the argument. Climatologists say that global warming… (wait, no one calls it that anymore) that climate change is due to people pumping huge amounts of greenhouse gases into the atmosphere. Oops. Some people still argue that our planet’s recent climate changes have a natural and not human-induced cause. Whew!

When weird weather happens, who is correct? The choice is yours.

Pollution 

  • Climate Change Nay-Sayers:  Tiny particles called aerosols get into the atmosphere naturally through lifted dust from deserts, evaporating droplets from the ocean and erupting volcanoes.
  • Climate Change Believers: Carbon Dioxide from car exhaust and trucks add to greenhouse gases, which cause global warming by trapping heat from the sun in the earth’s atmosphere. 

On Solar Cycles

  • Nay-Sayers: Changes in the sun’s heat output can be responsible for almost all the climate changes on Earth and Mars.
  • Believers: The radiation output of the Sun is only about one-tenth of 1%. This is not enough to affect the Earth’s climate in crazy ways, and not enough to be the only reason for why it’s so hot in here.

Arctic Melting

  • Nay-Sayers: The earth is recovering from the Little Ice Age that began in 1400. The shrinking expanse of Arctic sea ice is also a reason for the hot weather.
  • Believers: The loss of Arctic sea ice is because of human-induced greenhouse gas emissions combined with natural cycles. Industry, transportation, and biomass burning are releasing gases and particles that are polluting the polar region, forming an “Arctic Haze” every winter and spring. 

As you can see, this is an intense debate. So join the conversation and tell us, is it Mother Nature's fault or ours?
