Obama adviser ratchets up warnings on climate change


John Holden, assistant to the President for Science and Technology and Director of White House Office of Science and Technology Policy, says that without human activity, the world would be cooling now.  He reinforces Al Gore’s contention in his 2005 film “An Inconvenient Truth”, that carbon dioxide levels have skyrocketed due to human activity.  The severity of weather events (storms and droughts) has increased, although this assertion is debatable (we’ve always had tornadoes and hurricanes).  The Weather Channel has his audio interview here.
  
The rising of sea levels and spread of drought, however, is likely to impact lower income countries especially and increase political instability.
