For all their destructive power, tornadoes are small, localized events, and
can't offer much information one way or another on the subject of global
warming. A more useful, large-scale measure for weather evidence of
global warming is hurricanes.Extra heat in the atmosphere and the
oceans provides the extra energies needed to create larger, more frequent, and
longer-lasting hurricanes.Researchers recently announced that the
frequency of Atlantic hurricanes has doubled in the past 50 years.
We are heading into "uncharted waters". I'll continue to believe
the 97% of climate scientists who are telling us that climate change is a huge
threat, partially irreversible, and that we should all continue to minimize our
individual degradation of our environment. Leadership of this country should
also do everything possible to mitigate the nasty future that our children will
have.The climate-change models simply do not include what factors
cause huge tornadoes; that doesn't mean Barbara Boxer is wrong. But that
won't keep many, many Utahns from callously ignoring the facts...and making
up their own.
"Extra heat in the atmosphere" is a localized event too,is it not? The
"locality" may be relatively small or much larger. At all events it
seems that we are experiencing more unpredictable and unseasonal weather. Here in Utah, Idaho and elsewhere we seem to have had an unusually cold
winter and a cooler spring than for many years. That is neither global nor is
it warming. I believe we should hear something more, more detailed,
and more often, about thirty year averages and hundred year averages of
temperature and see if it all amounts to more than just rounding up and rounding
down of fractions of a degree. Local and Global.
I am surprised that schools in tornado alley do not have storm cellars.
Temperatures have not gone up the last decade or so despite more CO2 than ever.
Barbara Boxes embarrassed her self again by her Olympic leap of misinformation.
If global warming is worsening and thereby causing more severe weather, there
should be a measurable, predictable increase in the incidence of such events.
But Harold Brooks, a research meteorologist with the National Severe Storms
Laboratory in Norman, Okla., points out that "the 12-month period from May
2012 to April 2013 was remarkable for the absence of tornado activity and
tornado impacts in the United States." But who are you going to believe,
world renowned climatologist Barbara Boxer or real scientists like Dr. Brooks?
Hurricanes and volcanic eruptions existed before the industrial revolution too.
People have a descision on the issue not a knowledge.
Mr. Christiansen:You seem to think that fewer deaths due to
hurricanes since 1954 implies that there are fewer hurricanes or that they are
less severe now compared to previously. Does it not seem more plausible that
the improvements in detecting and predicting the path of approaching hurricanes
since 1954 could allow the population to make better preparations, and thereby
to save themselves from an approaching hurricane? The worst death tolls from
hurricanes in the past resulted from people not knowing that they were coming -
until it was too late.
"In a list of the 10 most deadly hurricanes since 1900, 9 of the 10 occurred
before 1954."Attribute that to better communication and warning
systems. We can't stop the hurricane, but we can let people know it is
Everyone likes to tout "facts," but prior to the Oklahoma tornado this
was a below average tornado season. The fact that "climate-change models
simply do not include what factors cause huge tornadoes" does not prevent
some in Utah from embarrassing themselves.
@Gordon Christiansen -- you have a problem with Senators Boxer and Whitehouse
telling the truth? Sad.
Furry1993, can you describe the legislation that could have prevented the
Oklahoma tornado? Even the most strident climate alarmists are forced to concede
that proposed solutions like Cap-and-Trade or a carbon tax will have no effect
on global temperatures. So blaming opposition to wildly expensive
"solutions" that don't do anything for the deaths of dozens of
people is rancid, vicious partisanship to the utmost extreme. Shame
One problem: This entire letter is factless hyperbole.Tornado
activity has actually INCREASED. "...the average number of April tornadoes
steadily increased from 74 a year in the 1950s to 163 a year in the 2000s. In a list of the 10 most deadly hurricanes since 1900, 9 of the 10
occurred before 1954. [To which you can thank your GOVERNMENT and real
SCIENCE for improved weather forecasting, increased building codes, and
multi-media early warning systems.]
Ms. Boxer is simply acting on the tried and true mantra of the democratic party.
"Never let a good crisis go to waste".Regardless of weather ther
rise in average global tempuratures is due to humans or not, we need to take
care of our environment.
"With the planet heating up, many scientists seem fairly certain some
weather elements like hurricanes and droughts will worsen. But tornadoes have
them stumped. Scientists have been pondering a simple question: Will there be
more or fewer twisters as global warming increases?Brooks and others
are looking at the ingredients that cause tornadoes. But even that isn't
simple. They look at two main factors: moist energy in the atmosphere and wind
shear. Wind shear is the difference between wind at high altitudes and wind near
the surface. The more moist energy and greater the wind shear, the better the
chances for tornadoes.The atmosphere can hold more moisture as it
warms, and it will likely be more unstable so that means more moist energy,
several experts said. But wind shear is another matter. Brooks and Stanford
University scientist Noah Diffenbaugh think there will be less of that.That would suggest fewer tornadoes. But if there's more moist energy,
that could lead to more tornadoes. One ingredient has to win out, and Brooks
says it's hard to tell which one will.(USA Today "How Does Global
Warming Affect Tornadoes?" 3/2013)
You don't suppose that, since 1954, building codes have improved, zoning
laws tightened, and warning systems upgraded to reduce deaths from hurricanes?
Um... why did the letter writer switch from tornadoes to hurricanes when
providing evidence? Okay here's the deal, the letter writer is
correct in that there's no global warming connection to tornadoes. The IPCC
report says as much. The trend is statistically insignificantly downward (we did
just go through record high and low 12-month tornado counts the past couple
years). The projections on it are rather split since more moisture and warmer
temperatures would help but decreased wind shear would hurt it. Hurricanes have been found to be getting slightly stronger over time (but not
more frequent globally, the Atlantic basin is the only one with a statistically
significnat upward trend, the other basins have statistically insignificant
downward trends). There are multi-decadal patterns to frequency though and
we've been in one favorable for the Atlantic for a while.As for
deadliest hurricanes and tornadoes (not sure which the letter writer intended
there), the reason they are mostly before 1950 is because we did not have the
satellite or radar coverage we have now. We'd be inadequately prepared.
Plus buildings were much less sturdy back then. That all combined for higher
@Mountanman"If global warming is worsening and thereby causing more
severe weather"It is, just not all types of severe weather
(floods and droughts both increase with severe weather since there's
stronger evaporation... which is bad for the drought risk, and the increased
moisture means more frequent heavy precipitation events which is bad for flood
risk). Tornadoes are one of the ones where it's not. It is interesting
though that the 12-month record low for tornadoes was only a year after the
12-month record high which covered spring of 2011. Shows the strong influence of
jet stream patterns on tornadoes.@LDS LiberalIncreases in
tornado counts have been primarily due to increased capacity to find, observe,
and report them. Controlling for that matter, the trend is statistically
insignificantly downward (basically flat). The IPCC finds no link between
climate change and tornadoes.
"you have a problem with Senators Boxer and Whitehouse telling the
truth?" Actually, I would love it if they could start
telling the truth, but not holding my breath! This whole issue is a joke, and
just like most things that leftists are passionate about, it involves half
truths and double standards. It doesn't matter what goes on with our
climate and weather, leftists will always come up with a theory about how we are
causing man-made climate change. This is all an orchestrated theory, so they can
take away personal liberty. Climate change has been going on for millions of
years...we don't need to get ourselves worked up and scared over nothing!
I live in Oklahoma and deal with tornados on a regular basis. It's not a
fun thing to go into an are to help clean up. I worked with the LDS church on
the Joplin tornado that wiped out the entire town just a few years ago. My heart
goes out to all the family's as I remember the tears that rolled down my
face when people thanked us for helping them. I will do the same in the next
couple of weeks. The Lord said we have Angles round about us, come help and
become an angle to the people that need us!
"This whole issue is a joke"Try tell that to those who have
lost their homes and businesses. Try telling that to those who are currently
digging their possessions out. Try telling that to the father or mother who lost
their dear child.It's fitting that the party of the rich would
call this horrible and costly weather a joke. Ill tell you a real joke, Wall
Street needing $900 billion from taxpayers because they failed so bad!
