Poetic justice, given that the US has dumped into the atmosphere more total historical climate change inducing CO2, by a wide margin, than any other nation.<div class="gmail_quote"><div class="gmail_quote"><br><a href="http://pdf.wri.org/navigating_numbers.pdf" target="_blank">http://pdf.wri.org/navigating_numbers.pdf</a><br>
<br>Page 32 of document above: US total from 1850-2002, 29.3 percent of world total, number one. Even assuming the EU-25's total, which includes many nations, the US alone still is number one. China ranks 4th with 7.6 percent.<br>
<br>We often hear in recent years that China is now the big climate change bad boy, given China's annual emissions that now probably exceed US annual emissions. But China remains far behind the US in total historical emissions. Given current trends, it will take many years for China to exceed the US total historical emissions, and if this occurs, it means humanity has failed to address climate change.<br>

<h1>Report: Climate change behind rise in weather disasters</h1><p><span>5:07PM EST October 10. 2012 - </span>The
number of natural disasters per year has been rising dramatically on
all continents since 1980, but the trend is steepest for North America
where countries have been battered by hurricanes, tornadoes, floods,
searing heat and drought, a new report says.</p><p>The study being
released today by Munich Re, the world's largest reinsurance firm, sees
climate change driving the increase and predicts those influences will
continue in years ahead, though a number of experts question that
conclusion.</p><p>Whatever the causes, the report shows that if you thought the weather has been getting worse, you're right.</p><p>The
report finds that weather disasters in North America are among the
worst and most volatile in the world: "North America is the continent
with the largest increases in disasters," says Munich Re's Peter Hoppe.</p><p>The report focuses on weather disasters since 1980 in the USA, Canada, Puerto Rico and the U.S. Virgin Islands.</p><p>Hoppe says this report represents the first finding of a climate change "footprint" in the data from natural catastrophes.</p>
<p>Some of the report's findings:</p><p>--
The intensities of certain weather events in North America are among
the highest in the world, and the risks associated with them are
changing faster than anywhere else.</p><p>-- The second costliest year
of the study period, 2011, was dominated by strong storms. Insured
losses in the U.S. due to thunderstorms alone was the highest on record
at an estimated $26 billion, more than double the previous thunderstorm
record set in 2010.</p><p>-- Insured losses from disasters averaged $9
billion a year in the 1980s. By the 2000s, the average soared to $36
billion per year.</p><p>Global warming combined with natural cycles such
as the El Niņo or La Niņa phenomena also intensify the risk of severe
weather. "This will result in higher natural peril losses and affect not
only the onset of heat waves, droughts and thunderstorms but also, in
the long term, the intensity of tropical cyclones," the report finds.</p><p>Reinsurers
such as Munich Re offer backup policies to companies writing primary
insurance policies. Reinsurance helps spread risk, so the system can
handle large losses from natural disasters.</p><p>"We see some trends
that are linked with changes in atmospheric conditions, such as more
water content in the atmosphere due to global warming," Hoppe says.
Additional water vapor in the atmosphere is the fuel for the big storms,
he says.</p><p>However, other experts take issue with Munich Re's
findings. "Thirty years is not an appropriate length of time for a
climate analysis, much less finding causal factors like climate change,"
says Roger Pielke, a professor of environmental studies at the
University of Colorado.</p><p>Another reinsurer, Axa, isn't quite sure
of the link either: "While a clear upward trend arises from the figure
with respect to the number of reported natural events, the attribution
of this rise to a climate change signal should be investigated very
cautiously," the French company says in its report "Climate Risks"
released earlier this month.</p><p>Atmospheric scientist Clifford Mass
of the University of Washington also has a problem with Munich Re's
findings, saying that once the data are adjusted for population there is
no recent upward trend in tornado or hurricane damages. Also, he adds
that there is no evidence that global warming is causing more extreme
weather in the USA.</p><p>Hoppe, however, says that even if we adjust
for population spread and increased property values, Munich Re still
says there were significant increases in the costs of weather disasters
over the past few years.<br><br></p>------------------------------------------<br>Vision2020 Post: Ted Moffett<br>
