America in
the Hands Of An Angry God - Extreme Weather Disasters of
Biblical Proportions and Changing Climate
The wildfire in Colorado Springs last month. This year the U.S.
saw its warmest spring since record-keeping began in 1895.
STORY HIGHLIGHTS
Droughts, wildfires and heat waves of Biblical Proportions have
plagued the U.S. recently
We've witnessed the warmest spring since record-keeping began in
1895
Heat waves in Texas and Oklahoma were exacerbated by climate
change
NOAA's climate data are increasingly helping states cope with
extreme events
In recent months, Americans have experienced numerous extreme
weather-related events, including droughts, wildfires and heat
waves of Biblical Proportions
We've witnessed the warmest spring since record-keeping began in
1895.
Thirty-one states reached record-high temperatures.
The period between July 2011 and June 2012 was the hottest 12
months on record.
And last year 14 extreme weather-related events caused an
incalculable loss of human life and cost the U.S. economy more
than $55 billion. Understandably, many Americans are wondering if
these events are manifestations of a longer-term shift in climate.
At present we cannot definitively link any single extreme event to
climate change. But it is worthwhile to consider whether the
apparent increase in some extreme events has roots in a larger,
longer-term trend, since that would predict a continuation of
these events in the future.
That kind of understanding can have practical importance because
it can inspire action to reduce economic losses and human
suffering — often in relatively simple ways. If a region is likely
to continue to get rainfall heavier than has historically
occurred, for example, then it is sensible for city planners to
consider installing larger-bore storm sewers when the time comes
to replace aging infrastructure.
The science in this area is getting stronger all the time. In one
recently published study, six international research teams led by
scientists from NOAA and a number of countries investigated seven
different 2011 extreme weather and climate events. In six of the
seven, there was sufficient evidence to conclude that climate
change caused by human activities played a factor in the events —
affecting their severity, likelihood or frequency.
Among those events exacerbated by climate change were heat waves
in Texas and Oklahoma, the East African drought and extreme
temperatures in Europe and England. On the other hand, the study
found no evidence that the devastating floods in Thailand last
year were connected to climate change.
Another new peer-reviewed article, the "2011 State of the Climate"
report compiled by nearly 400 scientists from 48 countries,
documents some of the longer-term trends that are underlying some
of these changes. It found that:
-- Carbon dioxide and other major greenhouse gases continue to
climb, with the 2011 yearly global average the highest yet;
-- Excess carbon dioxide in the atmosphere is making oceans more
acidic;
-- The Arctic is warming about twice as fast as the rest of the
planet, and its sea ice is thinning dramatically;
-- And the globally averaged heat stored in the upper ocean was
the highest since records began in 1993.
Such striking trends have strong implications for climate, weather
and environmental and human health.
One upward trend is indisputable: At NOAA, requests for climate
data have skyrocketed, and those data are increasingly helping
stakeholders cope with extreme events. Last year, for example,
firefighters in Texas used long-term climate information to
prepare for the spring/summer 2011 wildfire season. Emergency
managers along the Mississippi, Missouri and Red River basins used
NOAA climate data to help lessen flooding, months before it began.
Why we should expect more Biblical Strength weather disasters
Coastal managers are using sea-level-rise data to protect crucial
infrastructure.
Businesses and governments depend on climate information to make
smart investments.
Electric utilities count on climate data to anticipate peak power
requirements and distribute power where it is needed.
These are the kinds of practical actions that inspire me in my job
as we work to make the best science available to understand and
reduce the impact of extreme events on families, communities and
businesses. These and other measures are essential to reducing the
effects of extreme weather events and forging a safer future.
