The Truth About Climate Change

Fact: Plant life required carbon dioxide to exist.

Fact: Plants emit oxygen, required for humans to live.

So, we do away with as much carbon dioxide as possible, killing (or at least weakening) plant life which return the favour by giving off less oxygen.

Hey, presto! We all die and Earth goes on as it always has.

Fact: Animals exhale CO2
Fact: Plants have survived from the CO2 obtained from animals and humans way before humans even existed or started using fossil fuels.

So there's almost no chance of all plants dying from global warming regulations.





Fact: At CO2 concentrations of 200 ppm or less very little grows.
Fact: At high levels of CO2 plants grow like the dickens. All evidence we have shows that when the CO2 levels have been elevated the world was a much nicer place.

Fact: According to the geologic record in those rare times that the atmosphere has not been able to deal with elevated levels of CO2 the excess has gone into the oceans and precipitated limestone, thus sequestering the CO2 for later era's.
 
OK, dumb ass. Here is what the experts state;

AGU Position Statement: Human Impacts on Climate

AGU Position Statement
Human Impacts on Climate
Adopted by Council December 2003
Revised and Reaffirmed December 2007

The Earth's climate is now clearly out of balance and is warming. Many components of the climate system—including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons—are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6°C over the period 1956–2006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate.

During recent millennia of relatively stable climate, civilization became established and populations have grown rapidly. In the next 50 years, even the lower limit of impending climate change—an additional global mean warming of 1°C above the last decade—is far beyond the range of climate variability experienced during the past thousand years and poses global problems in planning for and adapting to it. Warming greater than 2°C above 19th century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity, and—if sustained over centuries—melting much of the Greenland ice sheet with ensuing rise in sea level of several meters. If this 2°C warming is to be avoided, then our net annual emissions of CO2 must be reduced by more than 50 percent within this century. With such projections, there are many sources of scientific uncertainty, but none are known that could make the impact of climate change inconsequential. Given the uncertainty in climate projections, there can be surprises that may cause more dramatic disruptions than anticipated from the most probable model projections.

With climate change, as with ozone depletion, the human footprint on Earth is apparent. The cause of disruptive climate change, unlike ozone depletion, is tied to energy use and runs through modern society. Solutions will necessarily involve all aspects of society. Mitigation strategies and adaptation responses will call for collaborations across science, technology, industry, and government. Members of the AGU, as part of the scientific community, collectively have special responsibilities: to pursue research needed to understand it; to educate the public on the causes, risks, and hazards; and to communicate clearly and objectively with those who can implement policies to shape future climate.

SO you have no defense for ignorantly posting the guy who is NOT an expert? Yeah knew that tool, and the AGU? Who cares that one scientific body buys into AGW theory? Matter of fact ONE of the scientific bodies that push the dam theory anyway... Dude its like trying a case by simply asking the defendant if he did it or not...:lol:

Are you serious? The earth is burning idiot and if we don't do anything about it we are going to burn. Have you not noticed every year it seems to get hotter and hotter for longer periods of time. I live in texas and that's one of the first places you will feel the heat. Global warming has been being watched for a long time and it has been said that we are getting warmer and warmer.

Honestly i think the ignorant should be you for not truly understanding global warming.

HUH?

No seriously you are confusing a local weather pattern with long term climate.. Its been hot in Texas a long time, longer than we have been populating it and its been a state. If you think its warmer in the years of your life living there, than perhaps you may be getting more sensitive to the sun just like a lot of us older people. And if you're to young to be more sensitive to the sun, you haven't been around long enough to make a long term climate change assessment.

Either way just popping in and calling me an idiot (if thats what you did cause its kinda hard to tell) doesn't make you a genius or a climate expert...:lol:
 
Are you serious?

Are you serious?

I live in texas and that's one of the first places you will feel the heat.

You must be feeling placebo heat brought on by your faith in those who tell you that it is getting hotter. Here is a chart from NOAA showing the annual temperature trend in Texas from 1895 to the present. The upward / downward trend since 1895 in Texas is a whopping 0.0 degrees. You are not going to burn and neither is Texas so you can stop wringing your hands and move if the western temperatures are to hot for you.

Global warming has been being watched for a long time and it has been said that we are getting warmer and warmer.

Yeah, lots of things have been said about the climate but when you look at the empirical data, few of them turn out to be true

Honestly i think the ignorant should be you for not truly understanding global warming.

Looks like it is you who lacks understanding. Operating from a poisiton of faith is no substitute for research.

hahahaha. if someone actually looked at the raw data for Texas instead of the 'adjusted' data, then there is probably a cooling trend.
 
Kiribati `bout to disappear under the ocean...
:eek:
Kiribati ponders floating island to fight rising sea
Thu, Sep 08, 2011 - The president of the Pacific island nation of Kiribati is so worried about climate change wiping out his country that he’s considering ideas as strange as building a floating island.
Kiribati President Anote Tong raised the notion yesterday on the opening day of a meeting of Pacific leaders in Auckland. Climate change has become a central theme of this year’s Pacific Islands Forum thanks to the presence of UN Secretary-General Ban Ki-moon, who has vowed to put the issue at the forefront of the UN agenda. Ban visited the Solomon Islands and Kiribati before arriving in New Zealand and said it only strengthened his view that “something is seriously wrong with our current model of economic development.” Tong said he’d seen models for a US$2 billion floating island, which he likened to a giant offshore oil platform. He said while it sounded “like something from science fiction,” every idea had to be considered given the dire situation facing Kiribati, a low-lying archipelago with a population of 103,000.

Other ideas to combat rising ocean levels include building a series of seawalls at a cost of nearly US$1 billion, Tong said, and relocating some residents to other Pacific nations. However, he said he couldn’t imagine a day that Kiribati was abandoned. “Would Kiribati disappear?” he said. “Never. Never.” Tong said some people have already lost their homes to rising sea levels. He said he’s yet to see much in the way of financial aid from Europe despite ambitious pledges. However, in an interview, European Commissioner for Climate Action Connie Hedegaard, who was attending the conference, said Europe has granted more than 7 billion euros (US$9.8 billion) for specific environmental projects around the world over the three years ending next year. “Climate change is not just a theoretical future. It is actually happening,” Hedegaard said. “It is destabilizing areas of the world.”

Hedegaard said she’s dismayed governments around the world haven’t reached broad agreement on reducing carbon emissions. However, she said she was heartened that many companies and municipalities are stepping in where governments are not — as much to save money on resources as for concern over the environment. “I see a lot of good things happening out on the ground now,” she said. Hedegaard praised Australian Prime Minister Julia Gillard’s push to introduce a tax on carbon emissions. That plan will go to a vote next week. Gillard, who has been facing political pressure at home and who has been criticized for her carbon-tax plans, told reporters yesterday that she was sure the tax plan would pass because it has enough support among lawmakers. The Pacific leaders leave for a retreat today on Waiheke Island before the conference ends.

Global warming threatens Antarctica with crabs
Thu, Sep 08, 2011 - The sea floor around the West Antarctica Peninsula could become invaded by a voracious king crab, which is on the march thanks to global warming, biologists reported yesterday.
The worrisome intruder is a bright-red deep-sea predator that previously had been spotted only in the Ross Sea, on the other side of West Antarctica. Taxonomists identified the crustacean five years ago, bestowing it with the lengthy moniker of Neolithodes yaldwyni Ahyong and Dawson and placing it among the 121 species of king crab. It is known as an “ecosystem engineer” because it digs into the sea floor to feast on worms and other tiny animals, an activity that in large numbers can have repercussions across the marine food web. A team led by Laura Grange of the University of Hawaii at Manoa lowered a remote-controlled scoutcraft as part of a long-term probe into biodiversity in the waters off the Antarctic Peninsula.

They looked at Palmer Deep, a mud-floored basin in the Weddell Sea located 120km from the edge of the continental shelf. The robot’s camera, trailed more than 2km, spotted 42 crabs, all of them at depths lower than 850m, where the water was a relatively balmy 1.4°C. By extrapolation, the crab population in Palmer’s deep — an area measuring 14km long by 8km wide — could be more than 1.5 million, Grange said. That density is the same as commercial crab fisheries in Alaska and the south Atlantic island of South Georgia. The images gave a glimpse of the kind of damage caused by the foraging crustaceans. The crabs, their shells measuring roughly 10cm across, had dug gashes up to 20cm into the soft ocean floor and thrown up lumps of sediment. The robot also retrieved a pregnant female crab, as proof that the species was reproducing.

None of the crabs were found at shallower depths, where the seas are colder. The implication is that as global warming heats the frigid coastal-shelf waters, which lie at depths of 400m and 600m, the way will be open for the crustacean to continue its creeping advance. The evidence from sea-floor sediment is that no so-called lithodid, or crushing, crabs have inhabited the cold shallow waters of the West Antarctic Peninsula for 14 million years. Previous research has already named the peninsula as one of the most vulnerable regions in the world for global warming. The waters of its continental shelf are warming at a rate of 0.1°C per decade. “If N. yaldwyni is currently limited by cold temperatures, it could spread up onto the shelf within one to two decades,” said the study, published in the British scientific journal Proceedings of the Royal Society B.

Global warming has become such a hotly debated issue that the country is polarized -- and most citizens get lost in the claims and counterclaims.

Manufacturers fear that these dire warnings will lead to more government regulation and anti-government factions believe that there is a climate conspiracy where top scientists have been caught cooking their books, falsifying temperature data, and excluding colleagues who disagreed.

Representative Michelle Bachman, whose Earth Day speech in 2009 was titled “An Ode to Carbon Dioxide,” made a claim that carbon dioxide levels are “a part of the regular cycle of the earth.” In pandering to her right-wing supporters it is easy for her to dismiss the problem because she won’t be around to see it happen.

The Truth About Climate Change

Is this guy trying to tell me that that CO2 caused an asteroid to hit the Earth 65 million years ago?

Are you aware that science, real science, has established that meteors caused at least two of those mass extinction events? Those two are the K-T and the Cretaceous events, and most scientist believe that other impacts explain the rest of the die offs. Am I supposed to worry about CO2 attracting asteroids?

If you want to talk about science you should learn some first.

Wow. Part of the regular cycles of earth. I'm sure that's something scientists haven't considered yet.

If the promoters of man-made climate fears truly believed the "debate is over" and the science is "settled", why is there such a strong impulse to shut down debate and threaten those who disagree?​

'Execute' Skeptics! Shock Call To Action: 'At what point do we jail or execute global warming deniers' -- 'Shouldn't we start punishing them now?'

Don't all scientists say that? Didn't Einstein ask to jail or execute scientists who doubted General Relativity?

An anonymous posting? That's what we're discussing here?!?! For all we know daveman wrote it himself. :cool:

Still pulling 'facts' out of your ass, Walleyes. Again, you are getting stupider daily. Just a look at the animals that went extinct at the end of the last ice age in North America demonstrates that the continent was far richer then in both plant and animal life. For there was a far greater variety of large animals then than now.

Abstract—A review of the glacial-age vegetation and flora of New Mexico concludes that, while the
snowline was 3000 feet lower in elevation with glaciers on peaks above 12,000 feet, vegetation zones were
compressed. The spruce-pine forests that today extend over 4000 feet of elevation in the mountains were
reduced to 2000 feet. The lower glacial-age forest border was similar to or slightly lower than that of today,
with tree and shrub taxa expanding their ranges into sagebrush grasslands along escarpments and rocky
terrain. The broad basins and plains of New Mexico, including the High Plains of eastern New Mexico and
adjacent Texas, were sagebrush grassland, a conclusion supported by vertebrate faunal studies and soil
profiles. The plant-macrofossil record is from glacial-age woodrat middens that are located on rocky
escarpments below 6000 feet elevation in southern New Mexico. The mix of montane tree and shrub taxa
in these low-elevation sites suggests that the glacial-age spruce-pine forest was more homogeneous than
modern forests.
 
At the CO2 minimums during the last ice age, there were vast forests and huge lakes in Eastern Oregon. And large mammals that disappeared about 10,000 years ago. Plants grew very well during the minimum periods for CO2 during the ice ages.

Which has it's own consequences.


ENN Original news: High Atmospheric CO2 Levels May Cause Mass Extinctions in the Oceans

One of the greatest causes of global climate change is the human emissions of greenhouse gases, specifically carbon dioxide (CO2). These emissions are released into the atmosphere, but much of it gets absorbed into the world's oceans. A new study, published in the Proceedings of the National Academy of Sciences, looked at prehistoric ocean sediment and found a disturbing trend. Periods of high CO2 concentrations have historically coincided with mass extinctions of marine organisms.
.............................................................................................................
However, unlike today, the hypoxia of 85 million years ago did not come from the mouths of rivers, but from the atmosphere. In that way, the resulting dead zones covered the whole globe. Marine wildlife had literally nowhere to go. The researchers showed that the extinctions occurred over extremely short periods (geologically-speaking) of only hundreds of years or less. Furthermore, they were caused by only modest changes in atmospheric CO2 levels and ocean oxygen levels

This alarming finding puts greater emphasis on halting climate change, to the degree that we can. Current high atmospheric CO2 levels pose a grave threat to marine life. According to the NASA Earth Observatory, dead zones have expanded tremendously in the past half-century. Martin Kennedy from the University of Adelaide in Australia said, "Earth's oceans are in a much more delicate balance during greenhouse conditions than originally thought."

if you look at the present climate change without using AGW-coloured glasses, nothing can be considered out of the ordinary. natural cycles. why shouldnt we be having a warm period like the Roman or Medieval ones?

it is very difficult to pick out information from the noise in natural evidence, as has been shown by the travesty of the Hockey Stick and the contortions that climate science has gone through to try and prop it up. if we are no warmer now (and we arent) than many times in the past why the hysteria now? AGW is only as popular as it is because people crave to be more influential than they are.

The Earth didn't warm as quickly in those periods as it has in the past 100 years. But I'd hate to ask you to understand numbers.

it is very difficult to pick out information from the noise in natural evidence,
That's why it takes trained scientists to do it and no moron armchairsmen like yourself.

Conclusion
Nature has provided us with data telling a simple story: For periods on earth comparable with today, we see many examples of temperature increases in the magnitude of 1 K for all kinds of natural reasons. Very rarely does any temperature rise (via supposed positive feedbacks) reach 3 K within 100 years.

It is thus surprising that IPCC and others with big confidence can claim large temperature rises of up to 3 – 6 K as most likely result from just a minor temperature increase, for example induced by CO2 warming.

More, it appears (fig 4.) that the temperature rise of 0,7K from 1900 to 2010 is as normal as can be when comparing with other temperature rises during other warm periods.
interesting article on temperature spikes in the last 1/2 million years via the Volstok Ice Core Data. it seems as if our present temp spike is pretty average.

on a different topic, the two factions fighting it out on this forum are acting like idiots by pretending that only their side has real evidence and that the other side is driven by distorted reasons such as politics, pseudo-religion or stupidity. there is a lot of evidence, some falling distinctly on one side or the other but most of it is equivical. exaggerations seem to rule the day, more on the CAGW side but that is only because they have more studies and more access to the media, many of the skeptics would be just as bad if given the chance.
