The idea that climate extremes are supposed
to get more frequent and in intensity is one of the most omnipotent present
manifestations of the climate doomsday religion.
Back in November 2009, there was an elevated
cyclone (Phyan) alert over Mumbai, coinciding with high tides. The last time
heavy rains and high tides combined almost as a lethal brew, resulting in
unprecedented flooding that almost totally paralyzed the city. Hence the heavy
media spotlight on the event. One popular English news channel had a Greenpeace
activist on its panel discussion who apart from parroting this ridiculous claim
made this remarkable statement:
"As a Mumbaikar, in my life time, I have alarmingly watched the
increasing cyclone frequency trend in the West Coast!".
The problem was that this was something of a
22 year old making a statement wherein he considered his miniscule life span
viz-a-viz earth's billions of year adequate enough to draw such a sweeping
inference. In fact a few hours after he made this statement, the cylone alert
was lifted for Mumbai city and the hysteria died as quickly. Actual empirical
evidence indicates that the frequency of cyclones and landfalls in the
West Coast as compared to the East Coast of India has historically been very
much lower. But this does not stop science illiterates of environmental
organizations like Greenpeace in trying to whip up hysteria on climate change.
There are of course decadal variations, but there is no definite long-term
trend in the frequency or intensity of tropical cyclones. Hence, the spectre of
tropical cyclones increasing alarmingly due to global climate change as
portrayed in the popular media and even in some more serious publications, and
by NGOs and environmentalists are pure myth as they do not have any sound
scientific basis. A peer reviewed study by Raghavan S. and Rajesh S. (2003)
published in Bulletin of the American Meteorological Society 84: 635-644
illustrates this in the clearest terms. We provide extracts of the review of
this study by a climate blog CO2 Science:
"There was a significant decreasing trend (at the 99% confidence
level) in the frequency of cyclones with the designation of "cyclonic
storm" and above, and that "the maximum decrease was in the last four
decades," citing the work of Srivastava et al. (2000).
They
additionally note that Singh and Khan (1999), who studied 122 years of data,
also found "increasing damage due to tropical cyclones over Andhra
Pradesh, India, is attributable mainly to economic and demographic factors and
not to any increase in frequency or intensity of cyclones." Hence,
they find that "inflation, growth in population, and the increased wealth
of people in the coastal areas (and not global warming) are the factors
contributing to the increased impact."
In other words, researchers have yet to find evidence of more-extreme
weather patterns over the period, contrary to what the models predict. There’s
no data-driven answer yet to the question of how human activity has affected
extreme weather,” adds Roger Pielke Jr., another University of Colorado climate
researcher."
The World Bank joined the bash by publishing its new paper (Read here) in the
Global Facility for Disaster Reduction & Recovery (GFDRR), virtually
rubbishes the claim of increasing damage on account of weather
extremities as given by the Stern Report, UK (2006). The latter report is
much used by NGOs and environmentalist organizations to buttress their case
that "time
is running out for a climate treaty". Here we provide extracts of this
report:
"Given empirical evidence about the link between climate and
damages, climate change is calculated to increase the damages from these five
extreme events by between $11 and $16 billion a year by 2100. There is little
supporting evidence that climate affects deaths from these events (except for
the possibility of local storm deaths increasing)....These values are
completely consistent with estimates in the literature per extreme event.
However, they are completely inconsistent with values stated by Stern (2006)
who suggests that extreme event damages could be 0.5 to 1.0 percent of GWP by
2050. Oral statements by Lord Stern even suggest values as high as 5 percent of
GWP by 2200.
The Stern analysis has been criticized because it confuses changes
caused by what is in harms’ way (baseline changes) with what is caused by
climate change (Pielke 2007b). But even this mistake cannot justify the
estimates by Lord Stern. The hypothesized damages quoted by Lord Stern are
completely inconsistent with empirical evidence....Using the minimum pressure
damage model, the estimated impact of climate change on tropical storm damages
ranges from $28 to $68 billion USD/yr (0.005 to 0.012 percent of GWP) by 2100.
This represents an increase of between 50 percent and 122 percent over future
baseline levels. Climate change is expected to double the damages from tropical
cyclones by 2100 by $54 billion USD/yr. The findings confirm the results of
earlier tropical cyclone studies that relied on cruder methods."
With the volume of empirical data as well as
theoretical analysis of the climate all contradicting the thesis that weather
extremities are increasing, climate alarmist scientists have apparently held up
the white flag. Gavin Schmidt, a prominent NASA climate scientist with their
Goddard Institute of Space Studies (GISS) who also administers the blog RealClimate.org
admitted in his blog the following:
1. There is no theory or result that indicates that climate change
increases extremes in general.
2. Attribution of extremes is hard
Last year, The Sunday Times exposed a controversy to the IPCC's 2007 report in
which a separate section warned that the world had "suffered rapidly rising costs due to
extreme weather-related events since the 1970s". It suggested a
part of this increase was due to global warming and cited the unpublished
report, saying:
"One study has found that while the dominant signal remains that
of the significant increases in the values of exposure at risk, once losses are
normalised for exposure, there still remains an underlying rising trend."
The Sunday Times has since found that the
scientific paper on which the IPCC based its claim had not been peer reviewed,
nor published, at the time the climate body issued its report.
Now that the thesis that climate change is inducing more weather extremities
have been firmly debunked, this has left prominent NGOs and environmentalists
red-faced, their credibility of their advocacy programmes in tatters. We give
some of the links that lest we forget what they had said in the past:
OXFAM: "A newly
released Oxfam report is blaming global warming for the four-fold increase in
the number of weather-related natural disasters - primarily floods and storms -
in the last two decades, alleging that the number has jumped from about 120 per
year during the 1980s to roughly 500 per year now. These disasters have exerted
a disproportionate impact on the world's poorest, the report goes on to say,
affecting more than 250 million people in South Asia, Africa and Mexico this
year alone.
This figure itself represents a 70% increase above average 1985 -
1994 levels, when about 174 million people were affected by natural disasters.
Appealing to the U.N.'s members ahead of the Convention on Climate Change in
Bali, Oxfam director Barbara Stocking warned that humanitarian assistance will
be overwhelmed and recent advances in human development will go into reverse,
unless immediate action was taken."
CHRISTIAN AID:"Climate
change is unequivocally taking place and some of the poorest people in the
world are already suffering from its effects. Higher global surface
temperatures and sea level rises are contributing to increasing frequency and
intensity of extreme weather events, with disastrous effects on individuals and
governments in developing countries"
ACTIONAID: "The threat
of climate change means the frequency and intensity of extreme weather events
will increase worldwide. The number of disasters, and those affected by
them in the developing world, is already steadily rising. With each new
disaster, precious gains in poverty eradication are lost or severely set
back."
GREENPEACE: "There is
strong evidence that extreme weather events - such as hurricanes, floods,
droughts and heat waves - are increasing because of climate change. In fact,
the Financial Initiative of the UN Environment Program (UNEP) recently
calculated that the economic costs of global warming are doubling every decade.
The cumulative number of people affected by disasters rose to two billion in
the 1990s, up from 740 million in the 1970s. Virtually all of these millions
were concentrated in poorer countries."
WWF: "Climate change
is directly affecting each and every one of us and threatens significant
physical and economic harm. While no single storm can be directly
attributed to climate change, the scientific evidence clearly shows that as the
climate warms, extreme weather events will become more intense and more
frequent."
