The science is clear arctic ice and ice on Greenland is declining because of human caused climate change.

269 billion tonnes per year since 2002 of ice mass.

What are your measurements A5?

Got your tape measure and scale out?

Or do you just look out the window and declare the earth looks flat like your buddy BL? Where is he BTW?

I don't keep track of Biglentil, but if I had to guess, he went for a walkabout to prove the the earth is flat, miscalculated how far the edge was, and fell off. Either that or else he discovered that it is actually round and should be back after making a full circumnavigation, with an apology.

I personally haven't measured the arctic or Greenland ice. But do you know who did? Mariners from the past millenium have kept sporadic records of the ice extent in the north sea, Iceland, greenland, and into the Canadian arctic in later centuries.

Do you know how todays ice extent compares to the historical record? Is there anything unprecedented about our current middle of the range sea ice extent?

In the era before human caused climate change, the ice certainly varied drastically, from far less than today, to much more during the Little Ice age.
Can your CO2 is the only cause of sea ice declines explain all the historical variations?

Or did all those factors cease to exist when CO2 started increasing?

[chuckChuck]

No one is saying human caused climate change or rising CO2 levels are the only cause of receding ice.

And scientists are saying that the trajectory of warming with increasing CO2 levels will result in continued melting and significant sea level rise over time.

Where is your evidence that CO2 levels and human caused warming are not causing ice loss?

Look at the graph of 800,000 years of CO2 levels that were never above 300 ppm and now they are at 425ppm.

The planet had several periods of glaciation and melting in that 800,000 year time period.

And no credible scientific organization is saying we are headed back to any glacial period with rising CO2 levels currently at 425ppm.

So, now I have to prove a negative?
Can you prove that you don't beat your wife (or husband, I don't want to make any assumptions in this day and age)?

I think you might be on to something.
So you are suggesting that there might be some other factor that could cause climate to warm and cool because glaciers have come and gone multiple times during the associated drastic temperature changes, all while CO2 levels remained consistent?

That seems plausible to any thinking person.

???????You see, this is a great example of why I continue to have these discussions with you. Occasionally you have a real epiphany and explain things so succinctly it almost anyone could understand it.

What factors do you think might be at work here? And are they still valid, or did the stop functioning when we started burning fossil fuels?

"there might be some other factor that could cause climate to warm and cool because glaciers have come and gone multiple times"


Like NOT humans? That could STILL be the reason!

[chuckChuck]

Look at the graph of 800,000 years of CO2 levels that were never above 300 ppm and now they are at 425ppm.

During the intreglacial periods that melted the previous glacial periods the CO2 levels were never above 300ppm. Now they are at 425ppm. Try to put 2 and 2 together A5.

We were at 280 prior to the industrial revolution and agriculture started about 10,000 years ago when CO2 levels were lower.

And no credible scientific organization is saying we are headed back to any glacial period with rapidly rising CO2 levels currently at 425ppm.
?

[fjlip]

So glaciers MELTED many times...because it got some how (not human influence), MUCH warmer, but C02 was lower all those times?

I See, C02 is NOT the cause or effect! You proved it! Thanks!

The Eighth Wonder of the World : How did millions of gullible lemmings get bamboozled into Climate Dysphoria when they only had to look at the facts? The ever-changing environment has many known influencers with still many still unknowns. Hang the dunce hats on the Crazy Crew (Gore, Suzuki, Libtards, Greta).

I'll try to paraphrase your statement.
Try saying this out loud and try to keep a straight face.

CO2 levels hardly changed for 800,000 years, meanwhile temperatures fluctuated by as much as 15 degrees C independent of CO2 levels.

Therefore, CO2 is obviously the control knob for temperatures.

Remember, you must keep a straight face while repeating this out loud.
no laughing out loud.

[fjlip]

Let that SINK in to thick Climatard brains....

independent of C02, independent of C02, independent of C02, independent of C02, independent of C02, independent of C02!

I See, C02 is NOT the cause or effect!?

[furrowtickler]

This is what’s actually going on …

[chuckChuck]

Do you not see the graph of CO2 levels going up and down for 800,000 years all below 300ppm? Now levels are at 425pp well above any of the last 800,000 years.

During that time there were several periods of glaciation.

So are you saying CO2 levels have no relationship to earth's temperature?

Which scientific organizations are saying this? And all we get is crickets! LOL

The flat earthers can't figure this out apparently!

And all you got is the experts are wrong?

What part of this don't you understand? For many of you I would say none of it!

"Earth's climate has changed throughout history. Just in the last 800,000 years, there have been eight cycles of ice ages and warmer periods, with the end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit ([url]http://climate.nasa.gov/blog/2949/why-milankovitch-orbital-cycles-cant-explain-earths-current-warming/[/url]) that change the amount of solar energy our planet receives.?

"The current warming trend is different because it is clearly the result of human activities since the mid-1800s, and is proceeding at a rate not seen over many recent millennia.^{1 ([url]https://science.nasa.gov/climate-change/evidence/#footnote_1[/url])} It is undeniable that human activities have produced the atmospheric gases that have trapped more of the Sun’s energy in the Earth system. This extra energy has warmed the atmosphere, ocean, and land, and widespread and rapid changes in the atmosphere, ocean, cryosphere, and biosphere have occurred.?"

[AlbertaFarmer5]

Yes, I oversimplified to stick to the theme you presented, regarding a stable level of CO2.
In reality, CO2 did respond to temperature throughout this period. Colder oceans during the ice ages sequestered so much CO2 that levels reached as low as 180 ppm at the end of the ice ages, nearly extinction levels. Then when the oceans warmed back up, and outgassed during the interglacials,CO2 levels recovered briefly each time.
Thank you for pointing out the relationship between temperature and CO2. Temperature absolutely does drive/lead CO2 during the ice age we are in.
I try to keep it simple, since you get so easily distracted otherwise.

[chuckChuck]

So who is saying that CO2 levels or temperatures are heading down again anytime soon? Nobody. So you don't have to worry.

But hotter and drier summers will still be good for us?

The biggest single cause of rising temperatures is rising CO2 and other GHG levels. Its scientific fact.

And there is no scientific dispute about the cause and effect.

[AlbertaFarmer5]

And there is no scientific dispute about the cause and effect.

You you really have no idea how science actually works, do you?
You have just denied the existence of the scientific method with that statement.
