Robert Hunziker writes at CounterPunch:
Climate change is not hot weather, and it is not cold weather. Those conditions have been around for eons.
Climate change is extreme anomalous weather conditions, like 100-year floods every few years rather than once every 100 years, e.g., Eastern Europe in 2013, or torrential downpours equivalent to annual rainfall levels but within one week, like Colorado in 2013, or embedded droughts that last for months, like Russia in 2010 when grain exports were halted, or subzero temperatures throughout North America in January 2014 because of anomalous jet streams, i.e. climate change conditions.
All of these extreme weather conditions that in years past happened on the odd occasion are now happening with increasing frequency, ferocity, and longevity. These conditions are becoming the norm and turn nasty by embedding for long duration because of climate change conditions.
As such, the saying “a 100-year flood” has become passé.
Severe anomalous weather occurrences can be, and are, measured by scientists. Thus, one can measure and know for certain whether climate change or regular ole weather patterns are happening. Here are some examples of climate change.
Droughts are a normal, recurring feature of the climate throughout the world. However, the normal, recurring feature, as of the past few decades, is turning quite abnormal or anomalous. To wit: According to Aiguo Dai, et al, Global Dataset of Palmer Drought Severity Index for 1870-2002: Relationship with Soil Moisture and Effects of Surface Warming, National Center for Atmospheric Research, Boulder, Colorado, 2004: “The global very dry areas… have more than doubled since the 1970s, with a large jump in the early 1980s… with surface warming as the primary cause after the mid-1980s. These results provide observational evidence for the increasing risk of droughts as anthropogenic global warming progresses and produces both increased temperatures and increased drying.”
As well, the World Meteorological Organization claims the planet experienced unprecedented high-impact climate extremes in the ten years from 2001 to 2010, the warmest decade since the start of modern measurements in 1850, The Global Climate 2001-2010: A Decade of Climate Extremes – Summary Report, World Meteorological Organization, published by WMO, 2013.
The warmest year ever recorded was 2010.
According to Michel Jarraud, WMO Secretary-General: “A decade is the minimum possible timeframe for meaningful assessments of climate change.”
Furthermore, the WMO report shows that global warming accelerated in the four decades of 1971 to 2010 and the decadal rate of increase between 1991-2000 and 2001-2010 was unprecedented. Global warming causes climate change, which, as the result of disruption of the jet streams above Alaska, in turn, causes bitter cold to hit the U.S.
The Year 2013 was all about Climate Change
Last year (2013) was all about anomalous weather as a result of climate change. Here are a few examples as explained in A Year’s Wild Weather – in two Minutes, BBC News, January 8, 2014:
- Australia- hottest summer on record books
- UK’s coldest spring in 50 years.
- A 17-mile wide tornado hit Oklahoma
- Canadian flooding – costliest in history
- India had worst monsoon in 80 years
- UK longest heat wave in 7 years
That is climate change.
