Is Climate Change Our Biggest Problem?|5 Minute Video
Is man-made climate change our most significant problem? Are the droughts, hurricanes and wildfires we see on the news a prophecy of even worse things to come? The United Nations and many political leaders think so and desire to invest trillions of tax dollars to reverse the warming pattern.

Script:
One of the most relentless claims in the climate debate is that worldwide warming leads to more severe weather. Lots of others have actually used comparable sentiments.
Global warming is a problem that requires to be addressed, however exaggeration does not help. It frequently distracts us from basic, cheaper and smarter options. To find those services, let’s attend to the three horsemen of the environment apocalypse to which President Obama referred.
Historic analysis of wildfires all over the world reveals that considering that 1950 their numbers have actually decreased worldwide by 15%. Quotes published in the Proceedings of the National Academy of Sciences shows that even with global warming, the level of wildfires will continue to decrease until midcentury and will not resume on the level of 1950– the worst for fire– before completion of the century.
Claiming that droughts are a consequence of global warming is likewise wrong. The world has actually not seen a general increase in dry spell. A study published in Nature in March 2014 programs globally that there has been little change in drought over the previous 60 years.
The U.N. Climate Panel in 2012 concluded: “Some areas of the world have actually experienced more intense and longer dry spells, in specific in southern Europe and West Africa, but in some regions dry spells have become less frequent, less intense, or much shorter, for example, in central North America and northwestern Australia.”
The 3rd horseman: cyclones. Worldwide typhoon activity today, determined by total energy, hasn’t been lower because the 1970s.
While it is most likely that we will see rather more powerful (however less) storms as environment change continues, damages will be lower due to the fact that we’ll be much better adapted. A March 2012 Nature study reveals that the international damage expense from hurricanes will be 0.02% of gross domestic product by 2100– down 50% from today’s 0.04%.
Let me make this clear: this does not imply that climate change isn’t a concern. It means that exaggerating the risk concentrates resources in the incorrect areas.
Consider hurricanes (though similar points hold for wildfire and drought). First focus on resilience– much better building codes and better enforcement of those codes if the aim is to reduce storm damage. Ending subsidies for typhoon insurance to prevent building in vulnerable zones would likewise assist, as would purchasing better facilities (from stronger levees to higher-capacity drains).
These options are relatively low-cost and fast. Most important, they would reduce future hurricane damage, whether climate-induced or not. Had New York and New Jersey focused resources on building sea walls and including storm doors to the subway system and making easy repairs like porous pavements, Hurricane Sandy would have triggered much less damage.
