• We don%26#039;t 100% know that changing cloud cover levels aren%26#039;t impacting global warming because there isn%26#039;t a lot of cloudcover data. However, the data we have (from satellites) indicates that this is not the case. The data shows that there is no long-term trend in low cloud cover. For example, see Figure 3 here:

  The other issue is that we know humans have caused atmospheric CO2 levels to increase 37% over the past 150 years by burning fossil fuels, we know CO2 is a greenhouse gas, and we know its global warming potential. So there%26#039;s really little question that CO2 is causing the planet to warm.
• Because no one has been able to demonstrate a 1% increase in cloud cover exists.
  
  We also don%26#039;t know that aliens beaming down heat rays aren%26#039;t causing it. Just as likely.
  
  What we do know is that basic physics proves the measured increase in CO2 would cause it. Given a demonstrated cause, scientists are understandably reluctant to accept the alien heat ray theory.
• And that accounts for temperatures and CO2 levels that have risen steadily since the 1880%26#039;s? Sure it does....NOT
  
  You%26#039;ve got to love that title though.
• I am sorry to say modern science is pro-profit for industries financing it.No vedic scientist is ready even to comment on it not to speak of relying on it. Vedic scientists
