The NCA, released on May 6, 2014 by the
US Global Change Research Program,
is the most comprehensive, authoritative scientific report ever generated
about climate changes that are happening now in the U.S. and further changes
that we can expect to see throughout this century. The report confirms that
climate change is affecting Americans in every region of the United States and
key sectors of the national economy. The findings about climate change are
translated from scientific insights into practical, usable knowledge that can
help decision makers and citizens anticipate and prepare for specific
climate change impacts. The new NCA is a result of a three-year analytic
effort by a team of over 300 climate scientists and experts, informed by inputs
gathered from technical reports, town hall meetings, public comment
opportunities, and technical workshops.
The assessment begins by stating that
"climate change, once considered an issue for a distant future, has moved
firmly into the present". The report discusses how climate
change will move directly into American homes, citing models that
show a potential for worsened rates of asthma, and higher pollen levels that
may trigger allergies, among other effects. The report states that
U.S. temperatures have warmed 1.3 to 1.9 degrees since 1895, with most of the
increase coming since 1970. Sea levels have risen and residents of some coastal cities see their streets flood more regularly
during storms and high tides. Inland cities near large rivers also
experience more flooding after heavy rainfall events.
Now how may this relate to those of you doing
your condition monitoring reports? It relates to you because you are collecting local condition data that helps assessments such as the NCA monitor localized changes. It also helps us collect the data we
need to collaborate with our partners such as the
National Integrated Drought Information System (NIDIS), the
Southeast Regional ClimateCenter (SECRCC) and the North Carolina and South Carolina state climate
offices, to report your findings so that we are aware of what is going on in
your town. As you continue submitting condition monitoring
reports, especially if you continue the practice into the future, you may run
into local changes yourself such as when certain trees or flowers bloom in your
area or changes in rainfall patterns. Keeping written records of this type of
information will help to document the types of changes we may begin to see and
when those changes begin to occur.
