As a geologist, I see change as the norm. For those that pretend to be scientist, yet suggest change is somehow not normal or inherently bad are simply ignorant of the facts. Dana tries to get around this by implying that somehow we are warming too fast and species can't adapt. Certainly more species die of cold than warmth, especially in the northern climes. Species dying is required for evolution to work but environmentalists wouldn't think of allowing natural extinctions to take place. That is what the Endangered Species Act is all about. They no doubt would (and constantly do) blame any extinctions on humans. The left would love to stop evolution and protect all species regardless of their fitness as they would like to keep the climate where it is, regardless of whether it might actually be better with some warming.

The basis for judging whether or not a climate is warming or cooling is not simply based upon temperature differences for one day. they are based on trends, taken over the whole year, grouped together with figures from several years and then compared with all known data regarding the climate temperature.
Warming may not be so bad for where you are, but in other areas it can lead to species extinction, drying up of ecosystems, water shortage to drought and crop failure. This could cause catastrophic changes in some areas followed by massive death tolls. And that is not even figuring in the severity of the weather as temperatures tend to rise.
Think past your personal little bubble, there is much more at stake. Just cause it is not affecting you, yet, does not mean it is not a serious problem.
EDIT - Did you know that scientists can determine the temperature of an area many many years in the past by taking a core sample and measuring the amount of oxygen present? So, using the excuse that we have only had accurate temperature measurement for 150 years really holds no water.

Weather can change, it's usually not a problem. If this year's temperatures differ from last year, that's weather.
When climate changes, bad things happen. If this 30 year temperatures differ from last 30 years, that's climate.
Unlike weather, climate has a huge inertia, that is, a huge resistance to change. So when climate changes, something very large, and very long lasting, must be forcing it. For natural climate changes, that big, long-lasting forcer is either changes in the Earth's orbit, or changes in the Sun.
For the current climate change, both orbital forcing and solar forcing can be strongly ruled out. Today's climate change is caused by human burning of fossil fuels. (It goes without saying that Earth's tilt has not changed 5 degrees in the entire history of the planet, much less the past century.)
Solar and orbital forcing eventually reverse themselves, because they are cyclic in nature. Human burning of fossil fuels shows no sign of reversing itself, and the CO2 we emit now will stay in the environment for centuries. That means that unless we take quick and drastic steps, the current climate change (unlike natural climate changes) will be permanent.
When we have seen natural climate changes like this in the past, it has caused global extinction on a massive scale, up to 50% of all plant and animal species wiped out. And it typically takes 10 million years for biodiversity to recover.

If you don't believe that the climate can be static, then it's either warming or cooling. Not necessarily. It's variable, from one year to the next. Conditions vary.
Why do I think warming is bad? I assume you mean human-induced climate change. But let's back up a bit, and identify the terms themselves, since respondents seem to play fast and loose with the terms on this site:
Global Warming is defined as an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution.
Climate Change is defined as a study dealing with variations in climate on many different time scales from decades to millions of years, and the possible causes of such variations. Human-induced climate change has the potential to alter the prevalence and severity of extremes such as heat waves, cold waves, storms, floods and droughts.
So the answer lies in the last section, the potential to alter the prevalance and severity of extremes. This in turn can affect agriculture in this country and elsewhere. From the Pew Center on Global Climate Change website:
"Climate change will result in agricultural shifts and changes across the United States. Given the requisite time and resources to adapt, the United States is likely to continue to be able to feed itself; however, there will clearly be regional winners and losers."
At the very least, it appears prudent to study and research how best to mitigate the impacts of climate change on U.S. agriculture. Complacency poses great risk. If efforts to fully understand and prepare for potentially severe impacts are delayed, the nation may face a future time-resource- ecological-and policy-crunch of monumental proportions.
My children are young adults, and there's a grandson with his future stretched out before him. I want him to have the best life possible, and that means doing my homework, becoming informed, sharing information, and doing what I can on a personal level to help my countrymen and women affect whatever change is necessary to help alleviate human impacts to the planet.

Its does not truly count variety, Y2K will wreck all of civilization anyhow. What? Y2K has come and long gone without impression? yet truly clever human beings gave truly truly grave warnings. element is that the earth is presently warming at a value of 0.7 stages in a hundred years. the sea is increasing at 2 mm consistent with year. the two considered one of that have been taking place via fact the final ice age. in case you complication, the water is going to swallow you up, then enable me supply this representation. in case you're sanding on the coastline on waters area, and the sea is increasing at 2 mm/year, then you certainly would be completely swallowed up by way of the sea in approximately 875 years. optimistically you may sidestep that. the sorrowful component is that on an identical time as all of the warmists look to have faith technological awareness, they in no way show you how to comprehend that the IPCC in trouble-free terms envisioned 0.2 to 0.6 meter sea point upward thrust in the subsequent a hundred years, and if we do no longer something and proceed to pump out CO2 at ever increasing expenditures, in trouble-free terms a three degree temp upward thrust. we don't even have sufficient oil to make their average predictions come real. yet they arrive around and take a investigate to scare with 20 meter rises, 9 degree temp will develop. extra the fashions used to foretell the three degree upward thrust in temps, envisioned it would be warmer this previous decade than it has actual been. In different words, even the predictions made that doesn't have catastrophic effect on mankind have been over priced. So sleep soundly understanding that each single end of the international prediction ever made and examined has shown to be fake, even whilst they have been made by way of "clever" human beings.

I believe the world is warming. I do not believe that man is the cause, nor does man have the means by which to stop, start or effect it in any way short of a nuclear exchange.

Simple - rapid climate change is bad for all species which are adapted to the current climate (either warming or cooling). We're currently warming at a rate 20 times faster than when the Earth naturally comes out of an ice age. If you think that's not bad for the species adapted to our current cliamte, that's a pretty tough argument to make.
Your last statement is wrong, by the way.
jim z - as usual you cannot refute the facts. Fact: the planet is currently warming 20 times faster than when it naturally comes out of an ice age. Fact: humans are the primary cause of this warming. Fact: all species on Earth are adapted to its current climate.
You don't and can't refute any of these points. Of course some species will go extinct naturally, but that's a completely irrelevant argument. The problem with geologists is that they only study the past, not the present or future. It makes them woefully inadequate to provide an informed opinion about the current climate change.

Global warming is bad because the glaciers are melting thus raising the waters in the oceans, which would cause cities on the coast of oceanic waters to be underwater. Which would displace millions of people or kill millions of people all depending on how fast the waters rise.

I personally do not buy into the whole global warming. first of all we have only been accurately recording weather for maybe 150 years. second the warmest year yet globally was back around the 30's. And, last, nature itself produces far more pollutants every year then man ie, volcanoes, forest fires and even animal gas.

To me, global warming and cooling is no problem. These are natural phenomnas.The earth has to reach its ultimate end , so is all creatures on earth. The process is so slow that we should not worry of our lives and 100 next generations.Leave at the time what is good or bad.No one knows what is in store of life.One atomic explosion can be worse than global warming or cooling.
