Is pollution a problem in in modern societies where cheap and abundant fossils are available?

Yes absolutely. There are multiple coal ash spills every year. Multiple oil pipeline leaks every year. Multiple mine tailing pond breaches every year.

One of my favorite rivers to fly fish in Wyoming just got royally fricked for years because of released silt buildup after negligence occurred attempting dam repairs.

Hell LA fisheries got buttfricked for years from the BP spill you think an LA board like this would want to enforce strict controls.

I will never understand how so many self proclaimed republican outdoors-men will stick their head in the sand over pollution and environmental controls. For fricks sake one of the items on the republican agenda this year was selling off vast swaths of public land to private companies to exploit natural resources. It's a shame that pollution control and conservation got lumped in with climate change and got politicized like it has.

climate change is real! man has little to no influence in the climate. one burp from a volcano has more effect than man's total historical influence. warming has been in effect since the ice age.

Can you source that statement?

The point is that no matter what old Mother Nature is doing, seven billion people acting in a careless and unrestrained manner are making it worse.

Feeling a Chill? Blame the Polar Vortex. And Global Warming.

"When these cold snaps come, you may hear other people asking,” If global warming is supposed to be warming the globe, then why is it so cold?”

Well, for starters, there is a difference between weather and climate. Climate refers to the long-term averages and trends in atmospheric conditions over large areas, while weather deals with short-term variations, which is what happens when the polar vortex visits your hometown.

And of course, an Arctic blast can still occur in a warmer world. The air that comes down from the North Pole might not be as cold, Ms. Barthold said, but it would still be the product of the same phenomenon.

Some studies suggest that climate change could actually make these frigid waves of Arctic air more common, a result of shrinking sea ice. However, other scientists remain skeptical of this theory.

And the earth is definitely warming: Temperature records show that, by the end of last year, the earth’s surface had warmed by about 1.8 degrees Fahrenheit since the 19th century. But even though the earth’s surface is warming, scientists say that winter will still exist.

And even if parts of the United States are experiencing unusually cold temperatures, it represents such a small portion of the earth’s surface — about 2 percent — that it does not mean much in terms of average global temperatures.

So, if, for instance, a senator (perhaps James M. Inhofe, Republican of Oklahoma) brandishes a snowball on the floor of the Senate to dispute the validity of climate science when a chill wind blows through Washington, you will know that the unseasonably cold temperatures he is talking about do not mean that global warming is not happening.

It is."

I would love to see the list of the Scientist who are on board with man made global warming, and who pays their salary.

The IRS is politicized.
The Justice Dept. is politicized.
The Supreme court is politiized.

We have proof that government controlled climate predictors have been intentionally changing the data.

We know those screaming the loudest, Obama and Gore, have not altered their life styles one iota. Except they have become more wasteful and extravagant since they joined the global warming parade.
Two Nobel prize winners are living in a manner destructive to the planet, according to them, should we take their message seriously?

"Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate."

Then I defiantly don't believe in global warming solely in terms of geologic time. In fact that the earth has experienced periods of global warming and global cooling.

I believe in both global warming AND global cooling as a function of time.

The last major volcanic eruption was Mt. Pinatubo. It was the 2nd largest volcanic eruption in the 20th century and it depressed global temperatures by about 0.5C for 2 years.

Those types of eruptions occur every 50 to 100 years. So, basically, a blip.

A Supervolcanic eruption would probably affect climate more significantly than we have, but those occur very rarely. One occurs every 50,000+ years.

Of course our total impact, at present rates, by the end of the century would exceed even that.

Strawman.

Here is a real world USA example of global warming. The two very violent hurricanes that blasted NOLA - Katrina and another - were birthed out in the Gulf where the temperature of the water is absolutely becoming hotter. That heat made the storms more violent.

We recently had some EF-5 tornadoes set down in the US. Same thing. Changes in temperature.


"With building designs taken more into account, winds in an EF5 tornado were estimated to be in excess of 200 mph (320 km/h). Since 1950, there have been 59 officially rated F5 and EF5 tornadoes in the United States and 1 F5 in Canada."

Q: What is global warming?

A: Here's a simple definition of global warming. (And yes, it's really happening.) Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And experts see the trend is accelerating: All but one of the 16 hottest years in NASA’s 134-year record have occurred since 2000.

Climate change deniers have argued that there has been a “pause” or a “slowdown” in rising global temperatures, but several recent studies, including a 2015 paper published in the journal Science, have disproved this claim. And scientists say that unless we curb global-warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next century.

Q: What causes global warming?

A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gasses collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect.

In the United States, the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year. Coal-burning power plants are by far the biggest polluters. The country’s second-largest source of carbon pollution is the transportation sector, which generates about 1.7 billion tons of CO2 emissions a year.

Curbing dangerous climate change requires very deep cuts in emissions, as well as the use of alternatives to fossil fuels worldwide. The good news is that we’ve started a turnaround: CO2 emissions in the United States actually decreased from 2005 to 2014, thanks in part to new, energy-efficient technology and the use of cleaner fuels. And scientists continue to develop new ways to modernize power plants, generate cleaner electricity, and burn less gasoline while we drive. The challenge is to be sure these solutions are put to use and widely adopted.

Q: How is global warming linked to extreme weather?

A: Scientists agree that the earth’s rising temperatures are fueling longer and hotter heat waves, more frequent droughts, heavier rainfall, and more powerful hurricanes. In 2015, for example, scientists said that an ongoing drought in California—the state’s worst water shortage in 1,200 years—had been intensified by 15 percent to 20 percent by global warming. They also said the odds of similar droughts happening in the future had roughly doubled over the past century. And in 2016, the National Academies of Science, Engineering, and Medicine announced that it’s now possible to confidently attribute certain weather events, like some heat waves, directly to climate change."

The scientists say a make or break is not far off. We have to heed that.

They've been claiming that the "tipping point" is here for the last 50 years. The passage of time without the climate tragedy happening is evidence they don't know what they're talking about. Don't you agree?

Do you believe in global warming?

Not as it is politicized. I believe earth's climate has changed dramatically over thousands of years and that will likely continue for thousands of years regardless of human factor. I'm fairly sure that much of the Northern Hemisphere (most of earth's landmass) would welcome some global warming.
