Easy .....it's just plain foolish , to think man can change any significant temperature to the earth

35 yrs of countless wheel barrels of money .....zero effect

If the globe really warmed by any measurable amount over the last 35 years we'd all be dead

Many records over the last 150 yrs still not broken

it's common sense, if you actually THINK about it.

and if you examine all of the different environmental "crises" over the last 50-60 years, the proposed "solutions" to every last one of them involve the developed countries giving up their competitive edge, while allowing every third world country to continue polluting in the same manner that they are decrying.

I guess you guys are just smarter than the phD's that have devoted their lives to studying these things. I'll just shut up then.

it's okay to be a dupe, beaverpeeler...we still love you.

I wonder how devoted they'd be ifn they got no pay check ?

Being that they hope their kids and grandkids have a moderately inhabitable planet to live on...I'll bet devoted enough.

Oh, forgot I was gonna shut up. LOL!

that would be much more care than the Algore and Obama-types demonstrate. they still fly on private planes and own oceanfront mansions...Rules for thee, but not for me!

Burning fossil fuels bad?

Guess Canada didn't get the memo, they're letting the forests burn with so much smoke you can see it from litter space, yet it's to expensive to put out. Go figure.

Wouldn’t the planet be more habitable if it was greener?

I’m always intrigued by somebody taking a definitive stance on something like this. You can follow the money on either side, and it takes you down a misleading path no matter the direction.

That said, I think it’s absolutely foolish to think humans can’t impact the planet in a meaningful way. What’s the percentage of land area that has been developed by humans for any reason? That used to be some form of habitat that no longer takes place in natural cycles.

In my 35 years I’ve personally seen signs of a changing climate. Multiple entire mountainsides of Alaska Yellow Cedar dead, glaciers that have sped up their recession exponentially (it’s been measured), I’ve personally fought wildfire, and a significant lack of snowfall during late deer season/Christmas compared to when I was a child. That’s just to name a few.

Are we impacting the Earth? Absolutely. Are we impacting it enough to end civilization? I donno. Haven’t been around for thousands of years, but it sure seems like we’re speeding things up.

Here’s my question to the climate change naysayers - what percent of Earth’s land area can be developed before humans cease to exist?

Use to be glaciers where you live Leroy, and they were gone before there were enough people here to have a square dance.

What happened to them?

They receded slowly.

Why?

Because the earth warms and cools in natural cycles, slowly, over long periods of time. Nobody is refuting that.

Do you believe humans can impact the Earth and affect natural cycles?

Slightly

I don't believe we can change what's happening to any great amount.

Good point. I would say humans are slightly speeding up the natural warming of the Earth.

And as the world becomes more developed then I think that rate of warming will increase.

Not sure how I feel about greenhouse gases. However, trees and vegetation naturally reflect UV light and shade the surface of the Earth. Pavement absorbs UV and heats the surface of the Earth. As we trade more vegetation for pavement I think we’ll see that increase. What’s your take?

It’s measured and irrefutable that big cities are, on average, warmer than, say, a small rural town. Why is that?

Now imagine all land area taken up by big cities across the globe and you’re saying we can’t impact the Earth in a substantial way?

Not measurably by any normal use of resources and renewable resources to sustain human life.....the planet is here for us to use ....


Can you give us examples of intentional destruction that will permanently damage the earth's ability to sustain human life....? Leroy brown

Big cities

Vegetation gone forever = increased UV absorption and warmer temps
Interrupted water cycles — would you drink well water in Portland?
Dirty air from increased vehicle exhaust and lack of vegetation filtering air — would you breathe directly from a car exhaust?
Where do you grow food?
What animals live there?
