DrW,
I know whenever someone says anything of a skeptical nature towards "climate change" (whatever that is without a precise definition) they are labeled anti science, "deniers" etc. Given this political rhetoric lets just stick to actual science.
What sources are you relying on respecting your disaster facts and a connection to anthropogenic global warming?
In 2011, the Federal Government declared more than 90 major weather related disasters. In the decade prior to 2011, the average was 56 per year. In the decade of the 1960s, the average was 18 per year.
In the last two years, natural disasters, most of them weather related, have cost the US Treasury close to $188 billion, or an average of some 2 billion dollars per week.
Yet conservative politicians, in the main, refuse to appropriate funds or approve legislation that would allow us to take reasonable steps to prepare for, or head off, this kind of day late, dollar short, catch-up spending.
Hurricane Sandy cost New York at least $60 billion. Effective seawalls and other infrastructure projects to protect low lying coastal areas of New York City against flooding from storm surges, if carried out when first recommended by climate scientists, would have cost about 10% of that amount.
There is no mention of hurricanes (like Sandy) in the extreme weather events section of the IPCC report. (
http://www.ipcc.ch/report/ar5/wg1/) The report gives low confidence to tropical storm activity being connected to climate change, and doesn't mention events like tornadoes and thunderstorms at all. It gives low confidence to drought and flood attribution.
This is consistent with what was reported a couple years ago in the IPCC SREX report ( IPCC Special Report on Extremes)
From Chapter 4 of the SREX:
“There is medium evidence and high agreement that long-term trends in normalized losses have not been attributed to natural or anthropogenic climate change”
“The statement about the absence of trends in impacts attributable to natural or anthropogenic climate change holds for tropical and extratropical storms and tornados”
“The absence of an attributable climate change signal in losses also holds for flood losses”
Nature published an editorial last year dashing alarmist hopes of linking extreme weather events to global warming saying:
"Better models are needed before exceptional events can be reliably linked to global warming."
It is also non-controversial that the earth has not warmed in the last nearly two decades. So how are connecting the FEMA disasters you cite as attributable to anthropogenic global warming when the correlating temperatures with your data show no warming?
Here are further quotes from the IPCC:
“Overall, the most robust global changes in climate extremes are seen in measures of daily temperature, including to some extent, heat waves. Precipitation extremes also appear to be increasing, but there is large spatial variability”
“There is limited evidence of changes in extremes associated with other climate variables since the mid-20th century”
“Current datasets indicate no significant observed trends in global tropical cyclone frequency over the past century … No robust trends in annual numbers of tropical storms, hurricanes and major hurricanes counts have been identified over the past 100 years in the North Atlantic basin”
“In summary, there continues to be a lack of evidence and thus low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale”
“In summary, there is low confidence in observed trends in small-scale severe weather phenomena such as hail and thunderstorms because of historical data inhomogeneities and inadequacies in monitoring systems”
“In summary, the current assessment concludes that there is not enough evidence at present to suggest more than low confidence in a global-scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century due to lack of direct observations, geographical inconsistencies in the trends, and dependencies of inferred trends on the index choice. Based on updated studies, AR4 conclusions regarding global increasing trends in drought since the 1970s were probably overstated. However, it is likely that the frequency and intensity of drought has increased in the Mediterranean and West Africa and decreased in central North America and north-west Australia since 1950”
“In summary, confidence in large scale changes in the intensity of extreme extratropical cyclones since 1900 is low”
Anyone still looking for real debate on climate change has missed their chance. The verdict is in on this one, and has been for some time. The issue now is what to do about it.
The debate isn't "climate change" the debate is anthropogenic global warming or man made global warming. The petition project demonstrates the debate is not over. The many previous scientist believers that have become skeptics demonstrate the verdict is not in. What are you relying on?
