Global Warming Is NOT Real By: Jamie Mullen and Monica Gawronski
Cooling Trend Over the last 11 years there has been a COOLING TREND. Sunspot activity is in a cycle in which it reduces warming radiation from the sun. This is causing a cooling cycle. The earth 1000 years ago is hotter than it has been today. The earth was warmer before. That did not have harmful consequences on humans
Greenhouse Effect Clearing of forests happens where governments own the forest. Private owners of forests results in a lot of growing and cutting. Yes, there is a greenhouse effect, but it's mostly caused by water vapor! H2O is much lighter than CO2.
Glaciers Glaciers in Greenland and Antarctic ice have been shown in the last few years to be actually getting thicker, not thinner.
Wrong Back in the 70's, the same governments and scientists tried to scare us with stories of the an ice age, and now we are supposed to listen to similar false information. Many companies made a lot of money from the ozone layer story. This has also since proven to be false, but the media which gave us a big scare at the time has since remained silent
Wrong— Continued Scientists have made wrong predictions before. It is argued that science and scientists are not always right. Perhaps they have made an error in their calculations or drawn incorrect conclusions on available evidence.
The Sky Is Not Getting Warmer
Man Made Technology Unreliability of computer climate models. It is argued that these models are not able to predict tomorrow’s weather. So how can they predict long-term climate change? Satellite readings of temperatures in the lower troposphere show no warming since 23 years ago.
People Not Believing
Natural Factors Natural factors are much more important than man-made factors in realising CO2 into the atmosphere. The ocean and volcanoes are much bigger sources of CO2 and other such greenhouse gases than humans. While the earth does go through periods of natural temperature fluctuation, the major increases in temperature and CO2 levels we are facing go far beyond the normal realm. Many experts believe that the world’s average temperature will increase by 2.5 to 10.4 degrees Fahrenheit by 2100.
