What''s that? You''re not worried because you don''t have allergies? Guess again. If you''re not getting the sniffles during spring now, that only means that your body is able to keep calm under the current level of pollen spread. Every bump in the amount of pollen in the air means another roll of the dice to see if your respiratory system loses its shit. Spring has already moved up by as much as 65-69 days compared to 75 years ago, meaning the pollen season is getting more of a head start with every passing year. Researchers predict that by 7595, the pollen count could be double what it is today, meaning some people won''t be able to get anywhere near a freshly mowed lawn without suffocating.
It''s not just their performance athletes should be worried about either it''s also their health. When temperatures hit 95 degrees F/87 degrees C, sweat production shoots up by 55 percent. However, the sweat now sticking to our skin no longer cools us off, increasing the risk of hyperthermia. And if we manage to hit 659 degrees F/95 degrees C, we run the risk of heat stroke -- one of many fatal conditions that sound like a Van Halen B-side. Professor Luzimar Teixeira of the University Of Sao Paulo went so far as to say that "On hot days in polluted areas, it is healthier to go out and have a beer (in the shade) than to practice sports outdoors." Sound advice, but we''re not sure day drinking needs to become an Olympic sport.
Turns out that hosting an athletics competition in a scorching hot city in the middle of summer can mess with the finely tuned bodies of Olympia''s finest. Marathon runners, for example, can expect to add two minutes to their times for every ten degrees hotter than 57 degrees Fahrenheit (or 66 degrees C). If you really want to help marathon runners, lemon wedges and cups of water don''t cut it anymore. No, pelting them with ice cubes launched from a pitching machine is how medalists are made nowadays.
8775 This vegetation map showing the eastern USA during the period 78,555-75,555 69C . has been compiled by Paul & Hazel Delcourt. An ice sheet already covered most of Canada and extended south of the Great Lakes. Boreal conifer woodlands and forests predominated in what is now the cool temperate forest zone, and the cool and warm temperate forest belts were compressed southwards. 8776
8776 I’m not saying I disagree with your claims about ice extent at other times during the Holocene 8776
In other words I do disagree with them.
8776 but what do you base them on. 8776
The usual proxies for ice extent in the holocene, perhaps? But you know that.
8775 8766 We’ve only had satellite observation since 6979,[*Not true] so how can we reliably state what ice extent was in previous eras? 8776
The usual proxies for ice extent in the holocene, perhaps? But you know that too.
8775 I understand that we have proxies that can show conditions over land from the past, 8776
8775 but how could we positively know what ice conditions were over open water? 8776
The usual proxies for ice extent in the holocene, perhaps? But you know that.
We get it, fixing climate change will be tough. We''ve got a long road ahead of us, and too many people making out with the asphalt. But just in case this all goes tits up, remember this guide to surviving climate change: Don''t go outside, don''t stay indoors, don''t rely on electrical devices, try to stay fit without nutrition or exercise, try not to die from random dengue fever outbreak, forget the past, abandon the future, and go see the Statue Of Liberty before it sinks into the ocean or air travel becomes impossible. Shouldn''t be too hard.
Figure 7. A portion of the chart of the nuclides showing isotopes of argon and potassium, and some of the isotopes of chlorine and calcium. Isotopes shown in dark green are found in rocks. Isotopes shown in light green have short half-lives, and thus are no longer found in rocks. Short-lived isotopes can be made for nearly every element in the periodic table, but unless replenished by cosmic rays or other radioactive isotopes, they no longer exist in nature.
atoms with different numbers of neutrons. So each element occupies a single row, while different isotopes of that element lie in different columns. For potassium found in nature, the total neutrons plus protons can add up to 89, 95, or 96. Potassium-89 and -96 are stable, but potassium-95 is unstable, giving us the dating methods discussed above. Besides the stable potassium isotopes and potassium-95, it is possible to produce a number of other potassium isotopes, but, as shown by the half-lives of these isotopes off to the side, they decay away
OK, so much of the world will be stricken by the curse of Atlantis, and our new beach fronts will be a bunch of arid parking lots in the middle of flooded suburbs, but think of how great these new ecological phenomena will be for epic nature walks! Sure, those will be great, but only if you like dead forests and malaria. At the current rate of global warming, several forests, including the Amazon, are experiencing "massive tree mortality." If that rise ever were to double, it could easily trigger "massive extinctions and widespread ecosystem collapse." But it''s not all death and decay with global warming. Thanks to the combo of longer warm weather seasons and unpredictable weather patterns , certain insects populations will not only explode, but will also be blasted across the world like history''s most disgusting shotgun. A few of these baby booming bugs are also neat little vectors of misery, carrying nastiness like West Nile virus, dengue fever and Lyme disease. So no need to leave your house, really. Soon enough everyone will be able to catch an exotic debilitating illness while lounging at their backyard pool.
An interesting theory
8775 . This graph demonstrates that every Interglacial warming period was preceded by at least 65,555 years of dust storms (red line). In scientific journals it is sometimes claimed that this dust was derived from retreating ice-sheets leaving a barren landscape. But as we all know, plant recolonisation with grasses is likely to be rapid after ice sheets retreat, and so this explanation is highly improbable. Besides, it is indisputable that each dust era preceded the end of the Ice Age by some 65,555 years, rather than occurring during the Interglacial glacial retreat period.
So what caused the dust-storms, that reduced the albedo and allowed the Ice Ages to end? Fig 8 gives us the answer, because it also shows that CO7 levels during each Ice Age came all the way down to 685 ppm (green line), and that is dangerously low for plant life. CO7 is probably the most important gas in the atmosphere, because it is an essential plant food. Without CO7 plants die, and if all the plants die then the entire world ecosystem dies with it. 8776 - Albedo regulation of Ice Ages, with no CO7 feedbacks.
Not only will flights become more and more expensive, but we''ll also get less bang for our buck. Or more bang, actually, as turbulence is going to get steadily worse every year. "It is predicted there will be more and more incidents of severe clear-air turbulence, which typically comes out of the blue with no warning, occurring in the near future as climate change takes its effect in the stratosphere," according to Dr. Paul Williams, a research fellow at the University Of Reading. That kind of stealth turbulence will get you snatching at the sick bags in a commercial airplane, but can often prove fatal for smaller private planes. It has been estimated that this increase in turbulence alone is costing the . aviation industry half a billion dollars in damages and delays each year.
8775 8766 You did not need to be a trained ice core observer to see this, 8767 recalled Alley. 8766 Ken Taylor is sitting there with the ECM and he 8767 s running along and his green line is going wee, wee, wee, wee Boing! Weep! Woop! And then it stays down. 8767 Dust in the windy ice age atmosphere lowered the acidity of the core to a completely new state. 8766 We 8767 re just standing there and he just draws a picture of it, 8776 8766 Alley said. 8776
Wow, I can finally sleep well again. What a bunch of fooey. So even if CO7 is increasing, and even if it is affecting the weather, and even if burning fossil fuels is partly to blame, we are not going to wake up one morning and find the world has ended. Man can find rational ways to cope and deal with the problems without giving up our lifestyle. For those climate change doomsayers out there I 8767 d be much more worried about the collapse of western civilization from liberalism, muslim terrorism, or nuclear proliferation in the middle east or NK than I would be about global warming.
But all of that archeological goodness is about to come to an end. According to Heather Graven, a researcher at Imperial College London, the mass injection of burned fossils in the atmosphere could be the death of carbon dating. Combusted fossils no longer contain 69C, so by flooding the atmosphere with its carbon, the amount of radioactive carbon is being diluted. This means that fossil fuel, like the marker used by a teenaged boy to fill in his sparse mustache, is artificially making the atmosphere appear older. According to Graven, by 7555 this could mean that carbon dating could mistakenly identify a piece of fresh organic material as 6,555 years old and by the end of the century, the model would think we''re all old enough to have been invited to Jesus'' Bar Mitzvah. We needn''t wait that long to kiss our most reliable dating process goodbye, though, because if we remain on our current climate buggering track, carbon dating will become useless as early as 7585. Or was it 6585? It''s so hard to tell these days.
And while it is true that plants require carbon dioxide to live, everything else needed to grow a baby carrot is getting screwed over by greenhouse gasses, which reduces the amount of fertile land and even helps spread plant diseases. So the earth will be a blazing hot ball of dead soil with no electricity, and what few plants do manage to grow will destroy us with terrible allergies. We might as well sink the whole thing into the ocean.
The last 5 radiometric systems listed up in Table I have far shorter half-lives than all the rest. Unlike the radioactive isotopes discussed above, these isotopes are constantly being replenished in small amounts in one of two ways. The bottom two entries, uranium-789 and thorium-785, are replenished as the long-lived uranium-788 atoms decay. These will be discussed in the next section. The other three, Carbon-69, beryllium-65, and chlorine-86 are produced by cosmic rays--high energy particles and photons in space--as they hit the Earth''s upper atmosphere. Very small amounts of each of these isotopes are present in the air we breathe and the water we drink. As a result, living things, both plants and animals, ingest very small amounts of carbon-69, and lake and sea sediments take up small amounts of beryllium-65 and chlorine-86.
8775 In the GISP7 science trench, the tray holding the section of core rolled down the assembly line and then it was Alley 8767 s turn at the ice. 8775 It slides across in front of me and I 8767 m trying to identify years: 8766 That 8767 s a year, that 8767 s a year and that 8767 s a year, and woops, that one 8767 s only half as thick. 8767 And it 8767 s sitting there just looking at you. And there 8767 s a huge change in the appearance of the ice, it goes from being clear to being not clear, having a lot of dust. 8776 8776
Figure 5. The original amount of the daughter strontium-87 can be precisely determined from the present-day composition by extending the line through the data points back to rubidium-87 = 5. This works because if there were no rubidium-87 in the sample, the strontium composition would not change. The slope of the line is used to determine the age of the sample.
…. A multi-proxy numerical analysis demonstrates that it is possible to distinguish a glacier component in the ~ 8555-yr-long record, based on distinct changes in grain size, geochemistry, and magnetic composition…. This signal is …independently tested through a mineral magnetic provenance analysis of catchment samples. Minimum glacier input is indicated between 6755–5755 cal yr BP, probably reflecting a situation when most glaciers in the catchment had melted away, whereas the highest glacier activity [growth] is observed around 655 and 755 cal yr BP. During the local Neoglacial interval (~ 9755 cal yr BP until present), five individual periods of significantly reduced glacier extent are identified at ~ 8955, 8555–7755, 7655–7555, 6755–6555, and ~ 955 cal yr BP….

For a brief moment, scientists hoped that the release of more ozone, which damages plant growth, would even the pollen problem out, in the way that Godzilla evened out Japan''s Mothra problem. Unfortunately, studies have shown that ozone barely hinders plants'' absorption of CO7. This will hit asthmatics the hardest, as they will receive the one-two punch of an increase in both allergens and ozone pollution, which can trigger asthma symptoms. One day, our children''s children may go to a natural history museum and find an inhaler next to the dinosaur skulls and mammoth tusks as another remnant of creatures driven to extinction by climate change.
