Again, there does not appear to be a human cause of the desertification of the Sahara 6000 years ago. What does that prove ? Please let us know the answer to this.

You tell me. You have no idea.

Ever wonder why temps don't rise as ice melts? You should.

Richard94611

Since the desertification of the Sahara and today's climate change are due to different causes, you must tell us what the Sahara has to do with today's climate change/global warming..

nwtk2007 Loc: Texas

Neither has to do with man.

Richard94611

OK, now I see the mistake you are making. One does have something to do with men and one doesn't, and you are a "confirmation thinker" who cannot accept eviddence contrary to what you want to believe. At least you are one step along the way in that you do believe that climate change/global warming is happening. Your problem is that you haven't accepted the facts about why. So be it. The world moves on, leaving you and your fellow deniers behind.

If you ever stumble across any of those "facts", be sure and let us know.

BTW: Since you seem to be so hostile toward men, why not just campaign to get rid of them instead of burying yourself in a huge load of irrational fabricated bullshit? No men, no problem.

Richard94611

Deniers, see if you can deny this. It comes from that liberal political publication, The Scientific American. I could subtitle this "A Few Facts for Blade_Runner."

World Shatters Heat Records in 2016
Last year was the hottest on record by a wide margin, with temperatures creeping close to a ceiling set by nations for limiting global warming
By Alister Doyle on January 6, 2017

Last year was the hottest on record by a wide margin, with temperatures creeping close to a ceiling set by almost 200 nations for limiting global warming, the European Union's Copernicus Climate Change Service said on Thursday.

The data are the first of the New Year to confirm many projections that 2016 will exceed 2015 as the warmest since reliable records began in the 19th century, it said in a report.
The Arctic was the region showing the sharpest rise in temperatures, while many other areas of the globe, including parts of Africa and Asia, also suffered unusual heat, it said.
A few parts of South America and Antarctica were cooler than normal.
Global surface temperatures in 2016 averaged 14.8 degrees Celsius (58.64°F), or 1.3C (2.3F) higher than estimated before the Industrial Revolution ushered in wide use of fossil fuels, the EU body said.
In 2015, almost 200 nations agreed at a summit in Paris to limit global warming to "well below" 2C above pre-industrial times while pursuing efforts to hold the rise to 1.5C as part of a sweeping shift away from fossil fuels towards clean energy.
Temperatures last year broke a 2015 record by almost 0.2C (0.36F), Copernicus said, boosted by a build-up of greenhouse gases in the atmosphere and by a natural El Nino weather event in the Pacific Ocean, which releases heat to the atmosphere.
In February 2016 alone, temperatures were 1.5C above pre-industrial times, the study said. Rising heat is blamed for stoking wildfires, heat waves, droughts, floods and more powerful downpours that disrupt water and food supplies.
The U.N.'s World Meteorological Organization (WMO), the main authority on global temperatures, compiles data mainly from two U.S. and one British dataset that will be published in coming weeks. It also uses input from Copernicus.
Dick Dee, deputy head of the Copernicus Climate Change Service, said Thursday's data were available quickly because they draw on temperature stations and satellite measurements used to make weather forecasts.
"They're pretty much in perfect agreement" with the WMO data in areas where measurements overlap, he told Reuters. The other datasets used by the WMO are collected from sources that can take more time to compile, including ships, buoys and balloons.
U.S. President-elect Donald Trump has sometimes called man-made climate change a hoax and threatened to "cancel" the Paris agreement. But he has also said he has an open mind and sees "some connectivity" between human activity and and global warming.

The case for warming is good. The case that it's caused by man, is weak

Richard94611

Well, I guess that means that we are halfway there as far as you are concerened. Tell us what you think causes the steady, yearly increase in warming.

nwtk2007 Loc: Texas

Normal cyclical changes overlaying upon each other, a little bit of man's effect, and other unknowns.

Richard94611

Why do you think that the temperature has increased steadily since the start of the industrial revolution, and that a graph of the amount of CO2 in the atmosphere increases the same way the graph of the temperature does? What about this little bit of temperature increase you feel is caused by man ? What causes that ?

nwtk2007 Loc: Texas

Thing have been warming, with ups and downs, since the last ice age. Man's Co2 emmisions contribute to that.

Blade_Runner Loc: DARK SIDE OF THE MOON

A computer model.

Richard94611

Wrong, Blade. A graph of actually recorded temperatures set against a graph of measured CO2 levels. Nice guess, but not good enough.

Richard94611

Well, perhaps we are getting somewhere. Yes, there have been ups and downs in the last 50,000 years. They have been due to different causes, incuding the three different, varying positions of the earth in relation to the sun. Those ups have melted ice and raised the sea level, and those downs have captured water that evaporated into the air, and then as the vapor hit higher, colder areas of the atmosphere turned into snow and ice, which then were deposited on the earth.

But we didn't care 50,000 or 20,000 or 10,000 years ago if the water level rose from increasing temperature, because there were no inhabited cities of Miami, New York, New Orleans, Boston or San Francisco, and the rising levels didn't affect mankind in these low elevation areas because mankind's cities were not in existence. We are concerned only because it affects us in the here and now.
