Is global warming bad?

I'm not kidding -- what's wrong with warmer temperatures? A few months back I was talking with an acquaintance who works as a meteorologist for Envirornment Canada. He made a comment that indicated that he thought global warming would be disastrous, so i asked him to explain why. He said, "widespread desertification." That didn't make sense to me, so I said something like this:

Why would increased warmth lead to desertification? Warmth doesn't make water disappear from the planet -- it increases the speed at which water evaporates, but evaporated water doesn't stay evaporated. It forms into clouds and falls back down to Earth as rain. An increased rate of evaporation means an increased rate of rainfall. Warmer temperatures and increased rainfall -- those are conditions in which vegetation grows and FORESTS spread, NOT deserts. If we look back in time about 150 million years to see what our planet was like in an era when the globe actually was warmer, we see, not a world-wide desert, but something closer to a world-wide rain-forest -- a place where life thrived and our ancestors* evolved. Now, I'm not saying that in the future we're going to have another world-wide rain-forest -- mankind won't let that happen -- my point is that a warmer planet is not inimical to life.

My meteorologist acquaintance didn't want to admit that I was right, but he did acknowledge that I had a point and that he couldn't think of an objection to what I'd said. And so our conversation politely passed on to other topics.

Of course, there will be problems associated with global warming. There are going to be a lot of people pissed off as their water-front property is flooded. But I don't see how global warming is going to be bad for mankind or the planet in the long run. The planet has gone through several cycles of warming and cooling and if I had to choose which cycle I'd want to live through, I'd choose a global warming cycle over an ice-age any day.

Incidently, my decision to post this was triggered by the comments of respect for David Suzuki over in the Greatest Canadian thread.

Shouldn't this be in the Conspiracy Theory thread??????

Been lots of info saying there is
and saying there isn't.

Tree huggers seem to leave out the amount of "green House gases" released by valcanos. They would have you believe only fossal fuel burning devices release it.

And have yet to prove and riase in temp is not normal based upon the history of this planet. After all record keeping is a little thin from oh say 600AD on back.

Warmer air holds more moisture. That's why it's muggier in the summer than winter. So increase evaporation will mean more clouds, but not necessarily more rain. Water vapour will just stay in the sky.

Warming oceans will also mean loss of coastal communities, as you mentioned. But the real danger are changes in the ocean temperatures.

All of the natural arable land on earth is there because of ocean currents. Change the ocean temperature will change the currents. What was tropical may become torrid, or desertified. What is now desert may become arable. What is now good, hearty forest may become swamp.

The thing is, we just don't know. There are too many variables and chaotic systems at work to give us any real indication of the consequences.

but isn't global changes one of the things sited by evelutionists as bringing about changes in the species? There fore would not global climatic changes just leave room for an elevolutionary bonnanza?

scientists can only predict what they think might happen. i'm sure in our life time we will be fine but what about our children's and grandchildren's? i find alot of people today to be very wasteful, especially in north america. if everyone just did their part in trying to be more environmentally friendly, it would make a huge difference. most of the time people opt for convienence rather than resourcefulness.

Remember el nino? That was a localized warming of the ocean. As for an evolutionary bonanza, remember that when a new species comes to thrive, other species (us) dissapear.

Does that the death of a species to bring about new ones
or so the theory goes


Assuming the human races is obliterated by global warming, will TERB survive with a new species at the helm?

I think that is a point... and the lack of any real assurances that man can "well survive" it. Face it, our science is pretty weak these days... we have no real ability to alter nature on a large scale... and it is a pretty frickin big game of roullette to play. Also keep in mind, global warming does not necessarily mean all parts of the planet get warmer... it does mean things will change though (commerce, food production, water supply, ...).

Of course since science is devided over the idea of global warming. The fear by the chicken littles may be an exercise in futility

The last 20 winters have been pretty mild. This week the temps will be around plus 10 degrees which is a bit high as well.
If this is not global warming then I dont know what is.

Try to stop it though, you'd have top take every car off the road and shut down all factories.
Aint gonna happen, no way!!!!

Decades ago, the alarmists were talking about another ice age coming. Now, the alarmists are talking about global warming. The “so called� climate experts can’t agree on any one conclusion.

The earth is ancient and it has climatic cycles. We’ve only studied this in the last few decades.

I can only conclude that we really don’t understand the earth’s long term climate trends and cycles.

When the Vikings discovered Greenland, they wrote that the land had small shrubs. Today, nothing grows there. It must have been warmer then than it is today to support the growth of small plants.

During Christ’s time, the holy land was green. Today’s it’s mostly a desert except where they irrigate.

Also, there was evidence that Egypt was once a much wetter and greener place than it is today.

There are coal deposits in both the artic regions, meaning that there was once plant life where nothing grows today. Obviously, the earth was a much warmer place during the time of the dinosaurs.

They talk about greenhouse gases causing global warming, yet I can’t believe that we human are making that big an impact. A single volcano irruption can generate more greenhouse gases than all the cars in the world could in 25 years.

There’s a lot more to this subject that we need to understand before we can start saying, “the sky is falling.�

Desertfication is not the problem. Desertfication is taking place due to other factors - deforestation, for example.

The real problem with global warming is water. I hope you like to swim, because once the polar ice-caps start melting...

If you build on sea front property you can gain or loose frontage based on tides. This is not news.

Tides? Sure, tides exist. But they're relatively regular and we have a good idea as to what the high water mark is.

But once the antarctic cap starts melting in a big way - which has already started, by the way - we don't know how high the high water mark will be.

Will Manhatten get inundated? London? Los Angeles? Vancouver? Tokyo?

We just don't know.

So, we have a choice: We can continue on the present path, the easy way out and do nothing, or we can take the hard decision to actually do something.

Will a decrease in CO2 emissions slow, or stop, global warming? Maybe. Maybe not.

What's the downside to decreasing the emissions?

Short-term economic issues, maybe. But economies are flexible, and taking the hard decisions to reduce emissions will undoubtedly spawn a plethora of value-added energy industries. So, in the long run, everybody wins. Even the oil companies, which will undoubtedly be at the forefront of the "new energy" industry.

And, if we're lucky, it may actually make a difference in global warming. If not, well, we'll just have to learn to live with the consequences.

But I guess a little hard work is too much to expect, when they've had it so easy for so long. A little foresight is not in the cards, when 90 days is considered a long-term strategy.

How do you stop the Co2 emissions from Valcanos???

How do you stop the production of Co2 from forest fires?

And if you hault the production what does that do to plant life?

What happens when you discover that hydrogyn as a fuel has a side effect we do not see today?

Are you willing to shut off the technoligy we have?

Couple of things
Costs involved?

Order reported by using this fuel.

Ok 3 things

What happens when technology improves and we find our assesment of the exhaust of this fuel was flawed by inaccurate science?
