Global Warming Proof?

Question

I'm not sure that i believe in global warming. Does anyone have evidence that answers these questions?;

1) Is the average global temperature rising?

2) is a higher temperature (in and of itself) a bad thing?

3) Can CO2 cause a global temperature increase on its own?

4) Is CO2 the major cause of this temperature increase?

5) are we causing the increased CO2 levels (if there is one)?

6) is an increased CO2 level (on its own) a bad thing?

7) Assuming you can answer yes to all of the above, is there anything we can do now to reverse it?

Please do not refer me to an inconvenient truth as i've seen that and 'the great global warming swindle' and remain unconvinced either way.

When answering please consider that we produce only 3% of the global co2 output each year and that any comparative data (CO2 vs temp) should go back to atleast the cretaceous period.

Answer 1

1. Yes. The global temperature averaged over 10 years has risen about 0.7° C since 1880. Here's the data: http://hadobs.metoffice.com/hadcrut3/dia...

2. The temperature in and of itself is not the biggest problem. It's all those other things that it causes. Sea level rise, for example, can wipe out entire nations and make hundreds of millions more into refugees. At the same time, nearly everything you eat has evolved under lower temperatures than the climate we're heading toward. Extinction and/or reduced planting range of significant food crops are things we should be looking at. Twenty angry people killed 3000 on 9/11; what can 500 million angry people do? No, it's not the end of the world. But it might easily be dystopia. Think "Mad Max" but without the cars.

3. Yes. (Although CO2 can also cause global temperature increase as a feedback from other initial causes, due to ocean-atmospheric feedback.) We know CO2 (and other greenhouse gases) are primarily responsible for the rise because of two "smoking gun" evidences that are proof of increasing greenhouse effect: (1) global stratospheric temperatures have been cooling over the last 50 years as surface temps are rising. This can only mean that heat is being trapped at the surface, which is a smoking gun for increased greenhouse effect. Here's the data:

http://hadobs.metoffice.com/hadat/images...

http://hadobs.metoffice.com/hadat/hadat2...

http://cdiac.ornl.gov/trends/temp/sterin...

(2) Nighttime temperatures are rising faster than daytime temps, inicating that a reduction in nighttime cooling is the major driver of the observed warming. Again, this is a "smoking gun" for increased greenhouse effect. Here's the data:

http://www.ncdc.noaa.gov/gcag/GCAGdealte...

4. Yes. Here's a chart showing relative contributions.

5. Yes, there is a CO2 rise; here's a graph of CO2 during the last 10,000 years:

http://farm4.static.flickr.com/3006/2615...

... and yes, we are causing the CO2 rise. Beyond the obvious sharp increase in atmospheric CO2 that coincides with the industrial revolution, isotopic analysis of atmospheric CO2 shows increasing amounts of "old" carbon combined with "young" oxygen. Here's the science:

http://www.sciencemag.org/cgi/content/ab...

6. Not necessarily, but again the effects are the killer; see #2 above.

7. Yes. We need to stop buring fossil fuels and begin relying on non-fossil energy sources. That means more nuclear, more wind, more biomass and more solar. Existing coal-fired power plants need immediate retrofitting with simple, cheap filters to remove CO2 from the air. http://www.sciencedaily.com/releases/200... The CO2 captured that way needs to be sequestered in environmentally benign ways that keep it out of the global carbon cycle for long periods of time. All this is possible, and not even terribly difficult. It requires only political will.

Answer 2

well this is years from destroying my life so ill be vain

Answer 3

The fact that you are unconvinced means at least you are thinking about it and because of that fact you are the same as me and need more proof. Decisions are being made on computer models and they can't be conclusive. We need far more evidence before sending the masses into debt. This whole global warming scenario is to stop undeveloped countries from developing. Nothing to do with the state of the planet. The planet is doing fine. It's all to do with money and oil. CO2 has nothing to do with global warming or Climate Change because I'm hard pressed to understand how a gas that 99.9% is at sea level and only .04% can heat the globe. The mountains still have snow on them and when that doesn't happen anymore then I'll change my mind.

Answer 4

1.  Yes.

http://data.giss.nasa.gov/gistemp/2007/

2.  When you get near 2C, definitely.  That will cause massive coastal flooding, and disruptions to agriculture which will cost hundreds of billions to deal with.

3.  Well, it needs the Sun.  But, if the Sun's radiation is constant (and data shows it pretty much is) CO2 MUST cause warming because of its' basic physical properties.  It's much like putting a blanket on the Earth.

4.  Yes.  It's the biggest greenhouse gas on this graph.

http://www.globalwarmingart.com/wiki/Ima...

5.  Yes.  Here it is.

http://www.globalwarmingart.com/wiki/Ima...

The previous high level for more than 500,000 years was 300.

Scientists have proven the increase is due to us by using "isotopic ratios".

http://environment.newscientist.com/chan...

6.  Yes.  See #3.

7.  Yes.  Reduce fossil fuel consumption by developing alternative energy and conserving energy.

What do you think?

Answer 6

1) Is the average global temperature rising?

Not at the moment but it generally has been since the little iceage around 1850

2) is a higher temperature (in and of itself) a bad thing?

We dont fully understand what the impacts will be, but we now when it was warmer in the past society generally benefitted, deserts became fertile land, growing seasons were longer, more agricultural land was available, plants bore more fruit and the land could sustain more wildlife, the seas didnt rise, etc...

In fact the sea has been rising at a constant rate for he last 10,000 years regardless of global temperature as the antartic is still retreating from the ice age (i.e its that last bit in the shade that hasnt melted yet). The rate is tytpcially 180mm per 100 years. The IPCC have reduced the sea rise predictions with every report and now to just above the 180mm rate.

So far no emprical evidence has been found for extreme weather in various studies, infact they found the opposite in many cases.

Some scientists also expect increased wind shear with warming and thus reduced hurricane activity.

Generally drier conditions result in lower soil moisture content which is one of the key factors in flooding. Shorter sharper rainfall and drier soil will result in less large scale floods.

And of course when its warmer less people will die from the cold, this will out weight the extra deaths from warming. And we know from history that when its cold people spent more time in doors and disease spreads faster resulting in more epidemics and death.

3) Can CO2 cause a global temperature increase on its own?

It has never happening in the past, but it is feasible that co2 could cause warming as it is a mild greenhouse gas, though it is only a small amount of the greehouses gasses. However there may be feedbacks that cancel it out, we dont really know. No hotspot in the troposphere has been found yet so there is no proof co2 or the greenhouse effect is driving the climate yet. It well maybe something else driving the recent warming we had been experiancing.

4) Is CO2 the major cause of this temperature increase?

As I previosuly said the signature for global warming has not yet been found indicating co2 hasnt been causing the warming we experianced from 1978 to 1998, though it may have a small impact (co2 accounts for only 0.054% of the greenhouse layer).

5) are we causing the increased CO2 levels (if there is one)?

The highest figure I have seen is 3% of co2 is human produced, thats 0.0016% of the greenhouse layer. Most of the co2 is given off by rottinng matter and the sea, natural proccesses. It has been higher than today during previous warm periods without manmade co2 production based on stomatal data. http://www.sciencemag.org/cgi/content/ab...

Ice cores were proved to be unreliable in 2007 as ice can absorb co2 hence why they show lower co2 concentrations in the past

6) is an increased CO2 level (on its own) a bad thing?

Firslty the greenhouse effect keeps the earth warm and is therefore a good thing. Co2 is essential for life on earth and is not a pollutant. higher co2 levels results in reduced stomata in plants, they grow faster and larger with more roots, they then require less water and can survive in harsher soils or dryer enviroments, this is why eygpyt was once fertile land during a previous warm period which was warmer than today. however, if co2 reached 1000ppm we would be in trouble as it would become hard to breathe!

7) Assuming you can answer yes to all of the above, is there anything we can do now to reverse it?

We have little impact on the climate and trying to tinker with it could be far worse than leaving things as they are. However, adding extra co2 to the atmosphere could have other side effects we have not yet realised. I think the important thing is to try and use more renewable energy sources rather than buring coal or oil regardless of whether co2 is an issue or not.

The following paper from the non-intergovernmental panel on climate change (NIPCC) explains the current science very well without bias and covers all the points I have mentioned:

Answer 7

There is currently no evidence that man has made any significant contribution to climate change.

Some interesting facts.

1. During most of the past 2,000 years, the temp has been about the same or higher. Currently, we are barely over the average for the last 2,000 years.

http://www.worldclimatereport.com/index....

2. During the medieval warm period (820 – 1040 AD), Greenland supported farming. Those areas previously farmed are now covered in glaciers. Obviously the melting and reformation of glaciers is a cyclical occurrence.

3. The earth experienced a little ice age which ended around the late 1860's or so. This is about the time man started recording temperatures. This would be like measuring a lake depth after a severe drought, then worrying about it flooding as it rose to normal levels.

4. The earth has been warming for the last 18,000 years, since the last major glacier time period. During this time frame, the glaciers have been melting at a fairly consistent rate. Also, for most of the last 1 billion years, the earth had NO glaciers or ice coverage.

http://www.museum.state.il.us/exhibits/i...

5. The AGW theory states that CO2 is the primary driver of temperature. They arrived at this idea because they did not know of anything else which could cause it. But during the 70's and during the current decade, temperatures dropped while CO2 continued to rise. This means that natural occurrences are driving temp, not CO2.

6. The Pacific Decadal Oscillation and sun spots provides a much better correlation to earths' temperature than CO2 levels ever have.

7. Polar Bears are experiencing a population boom. Coke sales in the arctics are through the roof. Polar Bears have been around for thousands of years, and remember, we are only at the average for the last 2,000 years. They lived through all the previously warmer climates. The original picture of 2 bears on a floating ice block was a complete scam. The photographer explained that the bears were in no danger and close to shore. The picture was lifted from a public PC by another passenger and sent around the world.

8. Many glaciers are expanding. Even Antarctica is growing on 98% of is land mass. Only 2% is melting.

http://www.telegraph.co.uk/news/uknews/1...

9. There is no consensus on AGW. This was a lie that has been propagated by the media.

http://scienceandpublicpolicy.org/monckt...

10. Yes we emit CO2 into the atmosphere and it is a greenhouse gas, but, we only contribute about .28% of all the greenhouse effect. Water vapor makes up about 95% of the greenhouse effect. CO2 and other trace gases round out the greenhouse gases at about 5% for all of them. Of that 5%, only 3% is CO2, and most of that is natural. Again, our contribution to the greenhouse effect is a paltry .28%

11. The spread of disease is not attributed mainly to temperature. If this were the case, Florida would be a giant festering disease ridden cesspool. Economic standing is the primary determining factor in the spread of disease. Poor cultures can not fight the disease or eradicate the pests like more successful nations.

http://online.wsj.com/article/SB12077886...

12. Natural climate disasters (hurricanes, cyclones, etc) have never been scientifically linked to global warming (whether natural or man made).

Answer 8

ARE YOU MAD?!

Answer 9

I think Global Warming is proven deeply affected Hong Kong, the most polluted city in this world. According to to day's published news released by the Health Deapartment of Hong kong, the death tolls of 2007 are in the followings.

1) 12316 had died with cancer. The drinking water is from China's Pearl River, full of heavy metal and chemical from industries.

2) 6372 had died with heart disease

3) 4978 had died with brain artilly

4) 2096 dad died with asthma.

Hong Kong is the most polluted city in this world and the air is full of toxic particulates.

Is this the proof of Global warming?  

Answer 10

Are you kidding me, Lock Goud S?

That's proof of POLLUTION, not GW!

They have nothing to do with each other!

Wow.
