Global warming

[Fz6Sa]

Look back over time and consider the \"true\" things that were later to be found false. Flat earth, leaches, witches, etc.

Leaches are still being used....... (Just had to):justkidding:

My take is the \\"Global Warming\\" issue is blown out of proportion and is not as extreme as many make it out to be.

Hellgate, I agree that I have also seen alarmist and sensationalistic articles and bits on TV that were hyperbolic and exaggerated. However, I do not think that the gravity of the problem is overstated in the general media.

It's not that the 2 degree increase, on average, will necessarily in and of itself prove to be the end of the world. It's that it is symptomatic of a tipping point being reached.

For instance, if enough polar ice melts it will change the salinity of the oceans and the currents that have prevailed for thousands of years will stop. This affects the 75% of the planet which is covered in water, causing major aquatic life dieoff, including probably most significantly changes in the plankton and all the life that depends upon it (which is everything).

There are many books written and studies that show that once we hit a certain saturation of greenhouse gases in our atmosphere, it becomes a runaway compounding effect the likes of which will be far beyond our ability to cope with.

The thing that tears me is that this is a survivability of the human species issue, yet even the super wealthy and powerful people who are working against greenhouse gas reduction and moving quickly to develop alternative fuels will suffer the same fate as everyone else. It's sad people in general are so shortsighted - will will all suffer this folly.

The point is that a major retreat in the amount of greenhouse gas production right now could possibly prevent us from tipping over a certain threshold from which there will be no return. Venus' atmosphere is comprised almost entirely of carbon dioxide, 92 times as dense at the surface as Earth's (the equivalent of being underwater 1 kilometer). I'm not saying that it will become like this on this planet, but it teaches us about the runaway greenhouse effect and its implications.

Sorry I'm rambling - I have had a s**ty day and I'm beat. As you were. :Flash:

Interesting document recently released .... data is accurate too.

I have trouble putting faith in an article written by Chris Monckton for the Science and Public Policy Institute. Christopher Monckton has been denying Global Warming for a long time. He's not exactly an unbiased source. He is also a journalist and not a scientist, so I'm not sure I trust his analysis. He has tried to pass off his aritcles as scientific papers before. I doubt that his analysis of the data wasn't affected by his own Anti-Globlal Warming views.

The Science and Public Policy Institute is also biased against GW. Every link on thier site links to another GW Denier site, like the Heartland Institue. It seems like they are only concerned with one side of the issue, which isn't the scientific way of looking at things.

Personally, I trust what the scientists write about GW much more than the journalists, politicians and celebrities. Here's a list of scientists and scientific organizations that believe humans are affecting the climate, and we need to do something about it before it's too late.

Below is a list of joint statements calling for action on mitigating climate change. The National Academies representing the 21 following countries and districts have signed joint statements:

G8 Statement

National Academy of Sciences: 2007 Joint science academies’ statement on growth and responsibility: sustainability, energy efficiency and climate protection:

The problem is not yet insoluble, but becomes more difficult with each passing day. A goal of confining global warming to an average of 2 centigrade degrees above pre-industrial levels would be very challenging, and even this amount of warming would be likely to have some severe impacts. . . .

We call on world leaders, especially those meeting at the G8 Summit in June 2007, to:
• Set standards and promote economic instruments for efficiency, and commit to promoting energy efficiency for buildings, devices, motors, transportation systems
and in the energy sector itself.
• Promote understanding of climate and energy issues and encourage necessary behavioural changes within our societies.
• Define and implement measures to reduce global deforestation.
• Strengthen economic and technological exchange with developing countries, in order to leapfrog to cleaner and more efficient modern technologies.
• Invest strongly in science and technology related to energy efficiency, zero-carbon energy resources and carbon-removing technologies.

Joint Statement I

Here is a press release from the National Academy of Sciences (USA) which opens with the words “Climate Change is real”. It’s conclusion begins with “We urge all nations, in the line with the UNFCCC principles, to take prompt action to reduce the causes of climate change, adapt to its impacts and ensure that the issue is included in all relevant national and international strategies.” It recognizes the international consensus of the IPCC (2001), IEA (2004), and UNFCCC.

Joint Statement II

Here is another press release from the Royal Society (UK) which says “The work of the Intergovernmental Panel on Climate Change (IPCC) represents the consensus of the international scientific community on climate change science.

The runaway theory is very suspect.

CO2 makes up .004% of the atmosphere (well really less but I rounded it up)

It requires expotentional increases in CO2 level to continue the heating curve.

Co2 levels have been higher in the past without runaway heating. Lower in the past without runaway cooling.
