HERE'S WHAT I THINK

 

Global warming is inevitable

Today's global warming is a result of past carbon dioxide emissions. Tomorrow's will be a result of today's.

To reverse global warming we would need to return to the emission levels we had before it all started. This is unlikely to happen...


This lens is a rough outline of my thoughts. Please join the debate. You can post comments about each topic or links to sites that agree--or disagree--with me.

Note: If you like my lens please give it 4 or 5 stars above.

Solar Activity 

Not all scientists believe that carbon emissions cause global warming. One theory is that variations in solar radiation and sunspot activity lead to changes in atmospheric temperatures.

If this is true and solar radiation is on the rise, then there is nothing we can do about it...

The following chart shows estimates. of sunspot activity, yellow, and temperature, red, over the last 10,000 years.

What do you think? Is there a correlation? Leave a comment below.

Does solar activity explain the increased temperature?

I think global warming is real. Mankind has a definite impact on the environment, from the toxic cleaners we use in our homes daily, the large amount co2 emmissions generated daily and a host of other contaminants. How can it not effect the enviroment! I recall back in the early 60's when I picketed Ford factories and other factories to clean up thier emissions. Luckily we have come along way since. Additionlly I recall when when the Cleveland's Cuyahoga River burst into flames from all the toxins in it and Lake Erie was once dead. I did a lens about the first Earth Day in 1970 with some interesting facts, and what we can do to sustain our environment. I hope you can visit.
PS I gave you five stars

I think if nothing is done now in 70 or 80 some years New York and a lot of other cities will be under 30 or so feet of water. People that deny Global warming really need to wake up and get a clue. Do you know how really bad it's going to be?

I live in Washington State and the weather is really getting strange. We had snow in April. We also had for the most part a mild winter and they have been getting more mild over the last 20 years at a rate that really shouldn't be happening if things were all good.

global warming can be avoided if proper step are taken

Man is an insignificant wart on the belly of the earth, and has no control over waht happens here. Just look at Colorado winters where the roads get closed when Mother Nature decides to dump 2 feet of snow.

Global Warming due to man's carbon emission is nothing butter hype and bullspit. People need to know the truth, but to get there, we need real facts, not statistics made up by a wanna-be presidential candidate.

The climate models we use today were written over 30 years ago, in FORTRAN! You cannot even find a comercially available FORTRAN compiler to rebuild the code, and it is all 8-bit, we get better resolution and accuracy from our Excel spreadsheets!

Stop the lies, before it costs us trillions of dollars in wasted beurocracy. . .

Sunspots have a very DIRECT impact on the earth- even those in airplanes are in danger when sunspots are active. There isn't a thing we can do about it either, except watch the aurora borealis when it arrives.

More on Solar Variation 

Solar variations are changes in the amount of solar radiation emitted by the Sun. There are periodic components to these variations, the principal one being the 11-year solar cycle (or sunspot cycle), as well as aperiodic fluctuations. Solar activity has been measured via satellites during recent decades and through 'proxy' variables in prior times. Climate scientists are interested in understanding what, if any, effect variations in solar activity have on the Earth. Effects on the earth caused by solar activity are called "sola...

Delayed Warming 

There is a time delay between the emission of greenhouse gases and the actual rise in temperature. The main cause of this delay is the heat capacity of the oceans. It takes years or decades for the incoming radiation to raise the temperature of the oceans.

Today's global warming is caused by past emissions. Future warming will be caused by today's.

We would need to do more than just stop the increase in emissions. We would need to go back to the pre-warming level of emissions.

It also may take centuries for natural processes to remove the extra CO2 from the atmosphere. So our current emissions will continue to affect the climate for centuries.

The following chart shows emissions for the past 200 years. Would we need to return to 1990 emissions? Or do you think we would need to return to 1950 emissions? Please post your thoughts below.

Forget about emmissions.

Do solar and wind power to get away from the turmoil and dependence on the middle east.

I don't thing we're going to unless there is no other choice- our entire economy is based on high usage of fossil fuels and consuming everything we can get our hands on. It won't be until it actually collapses for everyone on the planet that we'll change, because there won't be any other way.

Fact 1: Water vapor is a far more potent and far more abundant greenhouse gas than CO2. The CO2 contribution is trivial. People assume it's bad with very little evidence to support their assumption.

Fact 2: CO2 follows a diminishing curve. The means the 2nd unit of CO2 increase has less effect than the 1st. The third is even lower. For example, 100 units of CO2 increases temp by 1 degree, the next 100 increases it by half degree, the next by a quarter, and so on.

Fact 3: According to NASA the warmest years were before 1950 and the last few years have shown a flat temperature scale. So the spike seems to have little effect.

Fact 4: According to ice cores the historic temperature records show temperatures increasing 800-1200 years before CO2 increased.

More on Global Warming 

Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-twentieth century, and its projected continuation.

The average global air temperature near the Earth's surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations" via an enhanced greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial...

Books about the Science of Global Warming 

Positive Feedback 

As the arctic ice melts more solar radiation is absorbed by the dark water. This will accelerate the warming at the North Pole.

This is one example of positive feedback: Phenomena which speed up global warming after a small increase in temperature.

The following diagram shows the Arctic ice during the 1950's and the amount projected by 2050.

Global warming, arctic meltdown, pollution are certainly happening as you read this but the question is: What are we going to do about it?

The problem with projections into the future is that they are based on bad data, poorly written models that are incomplete, and bias from the lastest politically correct sicentists to prove the point.

And these guys are brainwashing all the students in engineering, so it is a self perpetuating problem.

These cooling and warming trends have gone on for mellenia.

The "Medieval Climate Optimum" records temperatures ~2 degrees warmer than now. Do you suppose industry back then was the cause?

Global warming is due primarily to solar cycles that alternately cause decreases or increases in solar wind.

Strong solar winds stave off streams off cosmic rays that would otherwise slam into the ocean's surface, releasing vast quantities of water vapour (the most important of the greenhouse gases) and CO2.

Al Gore and his henchmen just want to empty our wallets of our hard earned money. A serious side-effect of all this: We leave Africa in poverty by denying them the tools needed for development.

Dr. S. Fred Singer (Professor Emeritus of Environmental Sciences at the University of Virginia states, "There is no dispute at all about the fact that even if punctiliously observed, (the Kyoto Protocol) would have an imperceptible effect on future temperatures - 1/20th of a degree by 2050."

Great debate topic. I've added your lens to the Earth Hour 2008 lens, to get everyone to turn out the lights for one hour 8:00 pm on March 29, 2008 in an effort to raise awareness about climate change.

I think this has more to do with dramatic climate swings, super cold storms, higher heat, dryer summers, snow in unusual places, floods, tornados, hurricanes.
