National Academy of Sciences Calls for Urgent Action on Climate Change

This week the National Academy of Sciences - the premier scientific body in the United States - issued a series of reports on climate change.  They are compelling reading, arguing that action needs to be taken now to restrict carbon emissions and to adapt to climate changes that cannot be avoided.

Here are some relevant quotes from the NAS press release announcing the publication of these studies:

  • “Climate change is occurring, is caused largely by human activities, and poses significant risks for — and in many cases is already affecting — a broad range of human and natural systems,” [one] report concludes.  It calls for a new era of climate change science where an emphasis is placed on “fundamental, use-inspired” research, which not only improves understanding of the causes and consequences of climate change but also is useful to decision makers at the local, regional, national, and international levels acting to limit and adapt to climate change.
  • An inclusive national policy framework is needed to ensure that all levels of government, the private sector, and millions of households and individuals are contributing to shared national goals.  Toward that end, the U.S. should establish a greenhouse gas emissions “budget” that sets a limit on total domestic emissions over a set period of time and provides a clear, directly measurable goal.  However, the report warns, the longer the nation waits to begin reducing emissions, the harder and more expensive it will likely be to reach any given emissions target.
  • A carbon-pricing system is the most cost-effective way to reduce emissions.  Either cap-and-trade, a system of taxing emissions, or a combination of the two could provide the needed incentives.  While the report does not specifically recommend a cap-and-trade system, it notes that cap-and-trade is generally more compatible with the concept of an emissions budget.
  • Some impacts [of climate change] – such as rising sea levels, disappearing sea ice, and the frequency and intensity of some extreme weather events like heavy precipitation and heat waves – are already being observed across the country.   The report notes that policymakers need to anticipate a range of possible climate conditions and that uncertainty about the exact timing and magnitude of impacts is not a reason to wait to act.  In fact, it says boosting U.S. adaptive capacity now can be viewed as “an insurance policy against an uncertain future,” while inaction could increase risks, especially if the rate of climate change is particularly large.
  • Adaptation to climate change should not be seen as an alternative to attempts to limit it, the report emphasizes.  Rather, the two approaches should be seen as partners, given that society’s ability to cope with the impacts of climate change decreases as the severity of climate change increases.
