Climate change is happening in America’s national parks, and in some cases in rapid and concerning ways, says a new report authored by the National Park Service.
The changes will have implications for what visitors see and experience and will require new approaches to the protection of natural and historic resources within parks, the report says.
“This report shows that climate change continues to be the most far-reaching and consequential challenge ever faced by our national parks,” says National Park Service Director Jonathan Jarvis. “Our national parks can serve as places where we can monitor and document ecosystem change without many of the stressors that are found on other public lands.”

Climate change happens, that is not denied. The CAUSE of climate change, though, is often wrongly attributed to the activities of mankind.
Of all the factors that may affect climate on a relatively low level, perhaps heat “pollution” is one of the greatest, far greater than whatever “greenhouse” effect carbon dioxide may have. Water vapor, which has approximately the same heat absorption characteristics as carbon dioxide, exists in FAR greater quantities in the atmosphere at any one given time. Because of the nature of water, a rather unusual compound which can exist in all three states of matter (solid, liquid, and gas) simultaneously, and the enormous heat-carrying capabilities of water in all its forms, there is a powerful homeostatic effect on the temperatures of both our surface waters and our atmosphere, keeping it within a fairly narrow range.
When the solid form of water, ice, melts, it requires an astonishing amount of heat, some 80 calories of energy per gram, at 0 degrees Centigrade to become the same weight, 1 gram, of water at 0 degrees Centigrade. When the water is warmed 1 degree Centigrade, it takes about 1 calorie of heat per gram. To warm water to 100 degrees Centigrade, then, would require 100 calories per gram, at which point all water is converted to water vapor. The conversion of one gram of water to one gram of water vapor requires some 540 calories of heat per gram. So the melting of ice and the evaporation of water have HUGE potential for transferring heat. When the process is reversed, water vapor condenses to water, then the water is frozen to ice, all this heat that was absorbed is given up.
Now, water does not have to be heated all the way up to 100 degrees Centigrade to become water vapor. Water vapor may sublimate directly from ice to water vapor, though very slowly. Each degree water is heated, a greater and greater amount of it converts to water vapor, so on warm days there is more evaporation than on cool days.
But you knew that.
Mankind, even with its most strenuous efforts, can change no more than a tiny bit of this continuous heat exchange that is overwhelmingly dependent on the changing state of matter relative to the water molecule. We can, and have, harnessed this effect of heat exchange through the medium of water, to generate our power and extend the science of feeding ourselves through agriculture and manufacture of various products to serve useful purposes.
Those useful purposes utilize both the generation of heat, and the absorption of heat, to the degree that the overall impact is just about a zero effect in relation to the much more vast heat transfers that take place in nature WITHOUT the intervention of mankind.
A mile of ice over the Obama's residence sounds about right. Alas that missed by about 20k years.
I’m glad it’s limited to just the National Parks.
Of all the CO2 created on earth per year the entirety of human activity, all of it accounts for less than 3% of it... The idea of Anthropomorphic global warming is laughable on its face.
Yes is CO2 a greenhouse gas? Yes.. Do you know what else is and has a far greater greenhouse effect? Water Vapor.
Bingo, we have a winner! You are without a doubt 100% correct.
You'd think these educated types would have heard of it.
Instead, these crazy Global Warming people make this stuff up as they go, only to have to correct themselves later once the hysteria they're taking wears off:
I asked a lib once upon a time: “Is global warming worse in the summer or winter?”
I was quite amazed first that he answered “Summer” without pause or awareness of the sarcasm in the question, but was more amazed he spent the next 10 minutes explaining it was worse in Summer because it is hotter.
You have to give all these appointees credit. They are definitely of one voice. They all speak Booshit.
“I suppose when these idiots who spend the majority of their lives in air conditioned cars , offices and homes just happen to take a walk down the street, their climate is changing.”
That is the key as to why it was changed from “Global Cooling” to “Global Warming”.
As more and more people began working indoors with AC, when they left work the heat hit them like a ton of bricks.
Also more and more people began getting central AC and heat in their houses the temp was always the same.
Dress to go outside when its cold and you take some of the warmth from inside outside with you, not so with heat.
Dress to go outside when it’s hot, the cool from inside doesn’t go outside with you.
In the late 70’s, when global cooling was still popular, a lot of people from the northern states moved to Texas and they were the first ones I heard say it wasn’t global cooling but global warming because they weren’t used to the Texas summer heat.
Want to fix out national parks? Get rid of the national park service. As a matter of fact, if you want to fix anything that is hurting our country, get rid of the agency responsible for maintaining it.
