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

[Robert W]

Let me know when you actually want to have a rational conversation about something Robert.

I want to discuss you only.

I want to discuss you only.

That is not the topic of this forum Robert.

Help us all by telling us again what the topic is Crick.

I want to know who "Science" is because libs keep saying he's for Global Warming but he has no face or voice of his own.

I want to know who "libs" are? Cause folks like you keep saying they're all ignorant, amoral monsters and yet seem to be in complete control of everything. And it leaves me to wonder if the libs control everything, how is it you're still here yapping.

That's because they assume all warming is from an incremental 120 ppm of atmospheric CO2 and assume there is no natural warming which is an error on their part.

Excellent posts. I like to point out that the Democrats solution to what they claim is too much CO2 is to dramatically increase the size of Heavy Industry to produce billions of solar panels and wind turbines. A new heavy industry that operates around the clock, 24 hours a day, every day of the year, forever. Democrats are madly increasing CO2 levels.

Nobody is more certain that Co2 does nothing than the cowardly closeted communist who hid the FBI fraud case against the climate "scientists" in the CLOSET in 2012...

The link documents that homO went SILENT on the issue of climate change for two years, 2010-2012, even attending Earth Day celebrations by giving speeches that didn't mention climate or Co2.

This is because the FBI had a fraud case against the climate "scientists" and homO ended up hiding that IN THE CLOSET.

And that is validated because homO and Big Mike bought beachfront property on an island last hit by Cat 5 winds in 1938, meaning they are not afraid of ocean rise or a breakout in canes....

I do. I also feel free to urge you to act.

Mind your own business

Also what gives any Master of the Universe the right to spray chemicals into the atmosphere to reflect sunlight to make it cooler?

No one has any such right. Neither do they have the right to spray chemicals into the atmosphere that retain infrared and make it hotter.

CO2 emissions are not sprayed into the atmosphere.

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.

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.

Assuming this bilge is true, the smart money would be buying up all the northern land possible for future development and farmland.

 

[EMH]

All gasses, including O2 and Nitgrogen, hold heat, absorb heat, and warm planets.

I did.

I don't think buying a lot in a trailer park counts.

As has been explained to you too many times to be counted; "consensus" isn't scientific, it's political.

So, you would go to the first doctor who says you have cancer without a second opinion or or any one mechanic who says you need a new transmission or a plumber who over estimates your bill. . You’re lying to yourself. Literally everyone uses consensus all the time, let alone scientists.

That’s stupid…..you know nothing. The sun warms our planet and it doesn’t do it because it’s HOT. It does it by emitting radiation, dah

And to you, being hot has nothing to do with emitting EM....

LOL!!

I strongly suspect that you could not explain to us what you actually mean by "scientific" and "political". But I wouldn't mind seeing you try.
