Not exact matches
It follows that we can state, with a high degree of confidence, that
extreme anomalies such as those in Texas and Oklahoma in 2011 and Moscow in 2010 were a consequence of global
warming because their likelihood in the absence of global
warming was exceedingly small.»
Today's
extreme anomalies occur as a result of simultaneous contributions of specific weather patterns and global
warming.»
Yesterday, the analysis showed that Michigan experienced temperatures that were 4 — 5 climatological
anomalies warmer than average (4 - sigma to 5 - sigma), the type of
extreme that occurs between once every 43 years and once every 4779 years.
The clustering of
extremes occurs when natural variability creates
anomalies that are in the same direction as global
warming.
But examining temperature
anomalies separate from atmospheric circulation changes is dubious science at best and blaming global
warming does nothing to improve early storm warnings or accurately assess the frequency of
extreme events.
When a temperature
anomaly of ~ 0.1 degrees Celsius (the difference between 2015 and the previous global heat record of 2014 — please note the above graph is in Fahrenheit, not Celsius) can lead to such an
extreme carbon feedback response, we know we can expect a lot more feedback - induced CO2 now that world leaders are about to seal a 3.5 degrees
warming deal — if at least 2030 pledges are not raised before the start of COP21, the Paris climate summit.
Warming causes CO2 rise «Differentiating the CO2 measurements over the last thirty years produces a pattern that matches the temperature
anomaly measured by satellites in
extreme detail.
Day after day showed extraordinarily
warm temperatures, due to a persistent and
extreme jet stream
anomaly.
It clearly depicts the swings in «BE» climate change from the
warming of the MCA (medieval climate
anomaly) to the cooling of the LIA (little ice age) and the
extreme warming during the early 20th century (ETCW) from the 1920s to 1940s.
''... [the]
extreme anomalies... were a consequence of global
warming...» «Global
warming causes spring warmth to come earlier...»»... this level of average
warming is already having important effects»»... the dice loading is an expected effect of global
warming»»...
warming may cause snowfall to increase...»»... recent global
warming, with high probability, is responsible for recent
extreme anomalies»
The global temperature
anomaly certainly shows an increase since systematic thermometer records began in the tail end of the period of
extreme cold known as the «little ice age», but just as in the medieval
warming period, local temperature series need not correspond to the global trend.
The increase, by more than a factor 10, of area covered by
extreme hot summer
anomalies (> +3 σ) reflects the shift of the
anomaly distribution in the past 30 y of global
warming, as shown succinctly in Fig. 4.
... we can state, with a high degree of confidence, that
extreme anomalies such as those in Texas and Oklahoma in 2011 and Moscow in 2010 were a consequence of global
warming because their likelihood in the absence of global
warming was exceedingly small.
However, interpretation of the weak
warming trend in the United States matters because, if it is a statistical fluke, the United States may have in store a rapid trend toward more
extreme anomalies.
In other words, we can say with high confidence that such
extreme anomalies would not have occurred in the absence of global
warming.
The increase of these
extreme anomalies, by more than an order of magnitude, implies that we can say with a high degree of confidence that events such as the
extreme summer heat in the Moscow region in 2010 and Texas in 2011 were a consequence of global
warming.
One implication of this shift is that the
extreme summer climate
anomalies in Texas in 2011, in Moscow in 2010, and in France in 2003 almost certainly would not have occurred in the absence of global
warming with its resulting shift of the
anomaly distribution.
