Why Science Accepts Anthropogenic Global Warming and Tells Us We Need to Act

Urge all you want … I’ll feel free to buy a diesel Hummer.

That was always your call.

 

[fncceo]

That was always your call.

Then I take that as a public declaration that you repudiate any and all attempt to legislate what type of car I choose to drive, how I choose to heat and cool my home, and what appliances I use to prepare my food?

No. I didn't say it would always be your call or that I preferred it to be your call. I just said it always had been.

If the Earth had no atmosphere........

There would be no life of earth.

 

[Crick]

There would be no life of earth.

Do you generally have trouble handling hypotheticals? The point is that the argument that CO2 can't have a significant effect because it is such a small portion of the atmosphere fails on objective, quantitative analysis.

 

[Mashmont]

Give it up....We saw too much of this guy jetting around the world and spending billions to take any of your tripe seriously.

We all know the self-important doofus in our lives who makes confident forceful declarations about everything. And is wrong about everything.
Kerry's that guy.

If the Earth had no atmosphere, the planet's average temperature would be 58F (32C) cooler. Adding back just the oxygen and nitrogen would have almost NO effect on the temperature. That 58F of warming is due almost ENTIRELY to the greenhouse effect acting on two components of our atmosphere. About two-thirds is due to water vapor and one-third to carbon dioxide (CO2). The other components having greenhouse effects are methane, nitrous oxide, chloro- and hydrofluorocarbons.

The Earth began warming with the advent of the Industrial Revolution when the use of steam engines and then internal combustion engines grew rapidly, all fueled with hydrocarbon fossil fuels. The Earth is now warming at a historically extreme rate; twenty five times as rapidly as the Earth moved from glacial to interglacial states over the last 3 million years. That warming has been studied extensively for decades by scientists all over the planet. Their near-universal conclusion is that the primary cause of that warming is the greenhouse effect acting on CO2 emitted by humans burning fossil fuels (coal, petroleum, natural gas) for energy and transportation.

Up until the invention of the steam engine, CO2 in our atmosphere stayed in the range of 280 - 300 ppm for almost 3 million years. It is now just breaching 420 ppm, a 50% increase in the gas responsible for one-third of all greenhouse warming. That warming is reinforced by positive feedback from increased humidity in the Earth's atmosphere; water vapor is the most effective greenhouse gas but as a precipitable component of the atmosphere, changes only in response to temperature changes brought about by other agents. Atmospheric CO2 levels are also increased by deforestation and the thawing of frozen tundra.

The warming has numerous effects, many of which are harmful. Aside from its impact on all life forms via more frequent and more intense heat waves, we are experiencing sea level rise and increased ice melt. The energy that drives weather comes from the sun via the atmosphere and the hydrosphere. As global warming increases the energy available for weather, the average intensity of weather will increase. Increased temperatures are causing glaciers and snowpack to disappear. That decreases the Earth's albedo, decreasing the amount of solar radiation reflected back to space and providing more positive feedback. Increased meltwater from the poles is reducing the density of water there and thus the drive for the overturning currents responsible for the basis of almost the entire marine food chain as well as the temperate climate of Europe

Currently, thirty percent of human CO2 emissions are absorbed by the world's oceans. CO2 in aqueous solution produces carbonic acid which reduces the oceans pH (makes it more acidic). That change affects numerous biochemical reactions utilized by marine life, in particular the ability to fix carbonates into shells, exoskeletons and corals. The loss of corals will expose thousands of miles of coastlines to higher wave energies causing increased erosion and coastal flooding.

So, while some argue that added CO2 will increase agricultural production in some locales and that warming will be welcome by some residents in high latitude settings, the balance of warming effects are and will continue to be overwhelmingly negative.

The greenhouse effect is the process through which heat is trapped near Earth’s surface by substances known as ‘greenhouse gases.’ Imagine these gases as a cozy blanket enveloping our planet, helping to maintain a warmer temperature than it would have otherwise. Greenhouse gases consist of...

What is Ocean Acidification?

Ocean acidification refers to a reduction in the pH of the ocean over an extended period time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere.

LOL!!!

The FUDGE JOB...

Satellite data fudge excuse "orbit wobble" = laughable, wouldn't change the IR readings at all, much less change a flat line into an upward slope, which is what the FUDGE JOB did

Balloons had "shade issues" which were CONSTANT. Any adjustment would hence be a constant for all data and hence NOT change a flat line into an upward slope, but that is what the FUDGE JOB did


THERE IS NO ACTUAL DATA TO SUPPORT THE THEORY THAT ADDING CO2 TO THE ATMOSPHERE CAUSES WARMING AT ALL

NONE

TWO DATA SERIES = NO WARMING = urgent need for Co2 FRAUD to do yet another FUDGE JOB

The truth of the actual satellite and balloon data is that Co2 does ABSOLUTELY FUCKING NOTHING....
