Is This New Weather REALLY Because of Global Warming?
In one of my previous posts I had posed the
question that this new seemingly extreme weather might be the effects of global
warming. Here are two differing views to help you decide which side you’re on:
“Global warming is making hot days hotter,
rainfall and flooding heavier, hurricanes stronger and droughts more severe.
This intensification of weather and climate
extremes will be the most visible impact of global warming in our everyday
lives. People who have the least ability to cope with these changes--the poor,
very old, very young, or sick--are the most vulnerable.
More weather and climate extremes are likely
to impact U.S. energy security in ways that have not been adequately
considered. For example, major weather-related power outages are already
becoming more common, oil and gas infrastructure in the Gulf region is at risk
as hurricanes and tropical storms intensify, coal transport by rail and barge
across the Midwest and Northeast will face more flooding disruptions, and
electricity generation in the Southwest will be limited by water shortages and
more extreme heat.
Global warming will bring more extreme heat
waves. As the United States warms another 4 to 11°F on average over the next
century, we will have more extremely hot summer days. Every part of the country
will be affected. Urban areas will feel the heat more acutely because asphalt,
concrete and other structures absorb and reradiate heat, causing temperature to
be as much as 10°F higher than nearby rural areas.
Unchecked global warming will worsen
respiratory allergies for approximately 25 million Americans. Springtime
allergies to tree pollens are projected to get worse. In the fall, ragweed is
projected to thrive and become more irritating under increased carbon dioxide
levels. These potential impacts of global warming could have a significant
economic impact: allergies and asthma already cost the United States more than
$32 billion annually in direct health care costs and lost productivity.
Global warming is having a seemingly peculiar
effect on winter weather in the northern United States. Winter is becoming
milder and shorter on average; spring arrives 10 to 14 days earlier than it did
just 20 years ago. But most snowbelt areas are still experiencing extremely
heavy snowstorms. Some places are even expected to
have more heavy snowfall events as storm tracks shift northward and as reduced ice cover on the Great Lakes increases lake-effect snowfalls.
have more heavy snowfall events as storm tracks shift northward and as reduced ice cover on the Great Lakes increases lake-effect snowfalls.
Global warming is shifting precipitation
patterns and also increasing evaporation rates. These trends will create
persistently drier conditions in some places, including the American Southwest.
At the same time, they will intensify the periodic droughts that affect other
regions of the country. These longer and drier droughts will have major
consequences for water supply, agriculture and wildlife. Although the American
Southeast is typically thought of as having abundant water supplies, recent
droughts have served as a wake up call for the region.
Catastrophic wildfires just waiting to
happen. This is the situation now facing the American West. Wildfire frequency,
severity and damages are increasing because of rising temperatures, drying
conditions and more lightning brought by global warming, combined with decades
of fire suppression that allowed unsafe fuel loads to accumulate, a severe bark
beetle infestation that is rapidly decimating trees and ever expanding human
settlements in and near forests.
Global warming has caused more heavy rainfall
events in the United States over the last few decades along with an increased
likelihood of devastating floods. While no single storm or flood can be
attributed directly to global warming, changing climate conditions are at least
partly responsible for past trends. Because warmer air can hold more moisture,
more and heavier precipitation is expected in the years to come. At the same
time, shifts in snowfall patterns, the onset of spring and river-ice melting
may all exacerbate some flooding risks.
Stronger hurricanes, heavier rainfall and
rising sea level: this is what global warming has in store for the U.S. Gulf
and Atlantic coasts. The latest science indicates that maximum hurricane wind
speed will increase 2 to 13 percent and rainfall rates will increase 10 to 31
percent over this century. At the same time, sea-level rise will cause bigger
storm surges and further erode the natural defenses provided by coastal
wetlands that buffer storm impacts.
More and more Americans will be living in
places highly vulnerable to weather and climate extremes as population
continues to grow rapidly in cities, along the coasts and in the South. Racial
and ethnic minorities will be disproportionately impacted because their
populations are concentrated in these places. For example, 56 percent of
African Americans live in the Southern United States or in urban areas.
Furthermore, global warming will add further stress to existing problems in
urban areas, in particular poverty, inequities in access to health care, aging
infrastructure and air pollution.”

Now for a differing view on how it’s not the effects
of global warming:
“As part of my exploration of different surface temperature datasets, I’m examining the relationship between average U.S. temperatures and other weather variables in NOAA’s Integrated Surface Hourly (ISH) dataset. (I think I might have mistakenly called it “International” before, instead of “Integrated” Surface Hourly).
Anyway , one of the things that popped out of my analysis is related to our record warm March this year (2012). Connecting such an event to “global warming” would require either lazy thinking, jumping to conclusions, or evidence that the warmth was not caused by persistent southerly flow over an unusually large area for that time of year.
The U.S. is a pretty small place (about 2% of the Earth), and so a single high or low pressure area can cover most of the country. For example, if unusually persistent southerly flow sets up all month over most of the country, there will be unusual warmth. In that case we are talking about “weather”, not “climate change”.
Why do I say that? Because one of the basic concepts you learn in meteorology is “mass continuity”. If there is persistent and widespread southerly flow over the U.S., there must be (by mass continuity) the same amount of northerly flow elsewhere at the same latitude.
That means that our unusual warmth is matched by unusual coolness someplace else.
Well, guess what? It turns out that our record warm March was ALSO a record for southerly flow, averaged over the U.S. This is shown in the next plot, which comes from about 250 weather stations distributed across the Lower 48
Weather records are broken on occasion, even without global warming. And here we see evidence that our March warmth was simply a chance fluctuation in weather patterns.
If you claim, “Well, maybe global warming caused the extra southerly flow!”, you then are also claiming (through mass continuity) that global warming ALSO caused extra northerly flow (with below normal temperatures) somewhere else.
And no matter what anyone has told you, global warming cannot cause colder than normal weather. It’s not in the physics. The fact that warming has been greatest in the Arctic means that the equator-to-pole temperature contrast has been reduced, which would mean less storminess and less North-South exchange of air masses — not more.”

So How do you feel about the new weather? Do you believe it is the effects of global warming, or just nothing that should be a big deal?

Here's an Idea For You...
Recently I had almost an epiphany. I refer to it as almost
one because the idea might actually not work as well in reality as it does in
my head.
The US national debt is over 15.5 trillion dollars and
rising. Breaking that down, per citizen it’s about 50,000 dollars; per taxpayer
it’s about 140,000 dollars; the US federal budget deficit is about 1.3 trillion
dollars; and US federal spending is over 3.5 trillion dollars. (Deficit is per
year what debt we have while the debt is overall what has been accumulated.)
Now the whole idea of getting rid of the deficit is for
consumers to start spending more money so that aggregate demand will increase.
To do this, you’ll have to cut taxes and increase government spending.
–Which by the way, ignore the republicans budget idea for
the new election because it is a proven fact in economics that if they cut
government spending, we’re going to hit another recession. If government spending
decreases then aggregate demand does as well which means less GDP, less
spending, and a lower price level.
If we’re going to cut taxes then that reduces the amount of
money going into the budget. Also by increasing spending the government will
have to borrow the money in order to increase their spending, which in turn,
will increase consumer spending. So basically it’s just a vicious cycle of debt
and it seems there is no way out.
But here’s my idea. There are plenty of rich people out
there that earn billions a year or more and I bet that they don’t use every last
cent of that earned money. I think it would be extremely beneficial if everyone
that earns over 1 million dollars per year contributes to paying back our
national debt, just out of the goodness in their hearts. If they could
contribute each year more than 1.5 trillion dollars (all together) then we can
begin to bring the debt down and get this nation to feel secure again.
However, a lot of these rich people are just big jerks like
Mitt Romney and won’t help out the people who are affected by an increasing
deficit because they’re still earning millions to billions of dollars. Hell, I
even bet that some of those super rich people don’t even realize how big of a
problem this deficit is. They’re going to sit there and spend millions on a new
clothing line instead of helping out the nation they live in for our future
generations.
If I was a billionaire, I’d totally donate my money to
decrease the deficit and not expect a penny back.

Snow in Late April?!?
A large snowstorm came barreling through the Northeast on
Monday, threatening to drop 16 inches in some areas and frustrate commuters.
By Monday morning, Newfield, New York, was reporting 10
inches of snow, while Ridgebury, Pennsylvania, had 8 inches. More accumulation
was expected, especially in higher elevations.
The blustery blast follows a mild winter that saw little
snow and the warmest March on record.
"The last time we had a big snowstorm across the East
Coast was back in October," when fall foliage was still on the trees, said
CNN Meteorologist Rob Marciano. "This has been a crazy, crazy winter"
in the region, he said.
Snowstorms of this
magnitude are very rare for this late in April. Forecasters expect record
snowfall for this time of year in some areas. "We have a forestry division
on standby that they're going to be ready to respond to any tree problems and
issues that we have," Rob Kaczorowski of Pittsburgh Public Works told CNN
affiliate KDKA-TV. Regarding snow removal, he said, this "will be a wet,
slushy snow and we'll be in a plow mode actually pushing the slush off the
street."
The highest recorded snowfall for Pittsburgh on this date
was a half-inch in 1956. Up to 5 inches of snow are forecast for Monday, the
weather service said.
Snowfall rates in central Pennsylvania are expected to reach
1 inch per hour at times on Monday afternoon, said CNN Meteorologist Sean
Morris. One "bull's-eye is Dubois, Pennsylvania," he said.
Another is Erie, Pennsylvania, where snowfalls totals along
the southern side of Lake Erie could reach 16 inches, Morris said. "The
snow will be heavy and wet. The weight of the snow accumulating on trees
combined with gusty winds could cause branches to come down on power lines,
resulting in widespread power outages," he said.
Snowfall amounts of 6 to 14 inches are forecast for the
Allegheny Mountains of western Pennsylvania and near Lake Erie, the National
Weather Service said. Snow advisories also are posted for West Virginia,
western New York and extreme northeastern Ohio.
The snow won't last long, Morris said. Temperatures are
expected to rise into the 40s and 50s this week, with overnight lows remaining
above freezing.
Meanwhile, rain will challenge commuters along other parts
of the Eastern Seaboard for parts of Monday, spilling precipitation from the
Washington area into Maine. Flood advisories are in place across the region as
the forecast calls for 2 to 4 inches of rain and widespread urban flooding.
The storm could also play havoc with air traffic in major
business centers like New York, Philadelphia, Boston and Washington, which will
be subject to wind gusts of up to 31 mph in addition to the rain, forecasters
said.
The storm could also snarl New York City's sprawling mass
transit system.
The Metropolitan Transportation Authority was preparing for
potential problems, including the possibility of snow affecting Metro North
service upstate.
"The MTA has put together its emergency plans and
preparations," Joseph Lhota, executive director of the authority, told affiliate
NY1. "The subway system, Long Island Railroad and Metro North as well as
all of our bridges and tunnels are on alert with the concern of wind as well as
the amount of water that we're about to receive."
The Long Island Power Authority also braced for the storm's
fury. "LIPA crews are ready to respond to any potential power outages
caused by damaging winds and will work ... to restore power as quickly and
safely as possible," the utility's website said.
The system rained out both the Mets and Yankees baseball
games on Sunday.
A "pattern shift in the jet stream over the
weekend" caused the weather change, with temperatures dropping in the
country's eastern half and spiking in the west, said CNN Meteorologist Sarah
Dillingham. "This trend will continue through Tuesday and Wednesday,"
though by Wednesday temperatures will be working their way closer to normal,
she said.

After reading this it makes me happy to be in Iowa. We
usually have the worst winters here in the Midwest and now it seems as though
the tables have turned and now the other states get to experience what winter
really is. I even remember when it snowed in May when I was younger. However,
due to the extremely mild winter that Iowa had, our temperatures now seem cold.
But had we of had our normal winter weather, these temperature would be super
warm.
But one big question follows all of this crazy weather: Is
this the cause of global warming?...

Swimmers Don't Just Swim
When swimmers have to train for their upcoming
season obviously you would imagine that they swim a lot to prepare. What a lot
of people don’t realize, though, is that swimmers also need to do dryland
(workouts not in the water).
Abs are essential to every swimmer, there isn’t a
time in the water that they aren’t using their abs. Plus legs workouts like lunges
and squats also help for kicking. Finally, lifting helps the muscles grow
stronger so it’s easier to go faster in the water.
Iron and Exercise
When exercising, and especially swimming, there’s an obvious
need for protein. But what some people don’t realize it that iron is just as
necessary.
We can get iron from two sources: meat and fish or plant
foods. Even though both kinds are absorbed and used by the body, iron that
comes from meat and fish, rather than plants, is easier to be absorbed by the
body. The reason that iron is so helpful to a swimmer is because iron helps
transport oxygen to cells. If a swimmer is iron-deficient then there won’t be
as much oxygen going into the muscles. Considering that a swimmer uses every
muscle, oxygen is very important to have in them.
Oddly enough, as you age the need for iron increases. This is
because blood volume expands naturally. Below are the general requirements for
males and females:
Male
9-13 years: 8 mg per day
14-18 years
11 mg per day
Female
9-13 years: 8 mg per day
14-18 years: 15 mg per day
The reason that girls need to almost double their intake
of iron once they hit puberty is because of the loss of blood due to menstruation.
If you don’t get enough iron then it is possible to get fatigue or lack of energy, paleness, low body temperature, chronic infections/colds, and reduced academic performance. If you don’t have the sufficient amount of iron for too long, it is possible that you could then develop anemia.
Swimmers and other endurance athletes are at higher risk for iron deficiency anemia. This is because of blood cell breakdown during exercise, making iron more of a concern. Children and teens who are picky eaters, dieters, meal skippers or who have a poor quality diet (more junk food than healthy options) are also more at risk for iron deficiency.
Possible foods that are rich in iron include liver, red meats, poultry, and fish. As far as other foods go that aren’t meat then iron rich foods include spinach, kale, beans, tofu, fruits or raisins, iron-fortified cereals, iron-fortified bread, bagels, muffins, soy, almonds, and cashews.
If you feel like you don’t have enough iron in your diet, here are some tips on how to get more:
-Plan to include iron-rich foods at each meal.
-Vitamin C promotes iron absorption of non-meat sources. Pair citrus juices, fruits such as strawberries and mango, and other sources of vitamin C with plant-based iron-rich foods.
---Example: iron-fortified cereal with raisins and a glass of orange juice
-Protein helps iron absorption. When meat is combined with iron sources (the “meat factor,”), absorption of iron increases 2-3 times!
---Example: Enchiladas with lean ground beef and beans; steak and spinach
A great example is a simple iron-rich smoothie:
4-6 ounces of orange juice
½ - 1 cup of baby spinach leaves (or kale)
1 cup of frozen berries (raspberries, blueberries, or other)
¼ cup plain Greek yogurt or iron-fortified tofu
