Trudeau says he is quite a man because he won’t abandon,”the fight”.

This is what’s actually going on …

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."

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.

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.

[chuckChuck]

Which credible scientist and their organization says rising CO2 levels are not causing climate change?

Dont run away and hide. Answer the question.

[AlbertaFarmer5]

Sure crop!

Have you been to see the athabasca glacier? Is it shrinking or growing or staying the same?

I hadn't been to the icefields for a few years, so I thought I'd better check and make sure the trend is still positive. We stopped by yesterday evening. And sure enough, the glaciers are still going the right direction, nothing to panic about yet.

Funny thing about all the signs they have. The signs indicate that the melting in recent times is due to CO2, they even tell the viewer the steps we can take personally to stop them from melting. But the signs that show the maximum extent of the glacier in the 1840's, don't attribute any cause for why the glacier receded back then before man made global warming had been invented as the catch all to explain all weather events.

They even go so far as to admit that the glacier once extended all the way to the prairies, before somehow receding back to it's current position. The signs didn't indicate how burning fossil fuels had caused that to happen.
They even acknowledged that the glaciers were growing during the Little Ice Age( although they never used that expression). What I couldn't find were any signs indicating the growth of the glacier during the Little Ice Age, prior to it cycling back to shrinking in the 1840's. Probably just an oversight. Chuck, you seem to be an expert glaciologist, is the current extent of the glacier greater, or lesser than it's minimum extent during the Medieval Warm Period?

If I get my time machine tuned up, and go back to ~1250 AD, then stood where the toe of the glacier is today, would I be standing on ice, looking down at the toe, or standing on rock looking up at the retreating toe?

[sumdumguy]

From my memory it has grown 2 millimeters a year.

[AlbertaFarmer5]

Ice is still there, still shrinking, same as it has been doing for the past 170 years.

[WiltonRanch]

Funny you mentioned 1250 ad. Around the same time the prairies were in the grips of an epic decades long drought according to the fossil records. The North Sask River ground to a trickle and lots of wildlife perished. Would imagine a lot of first peoples suffered as a result or migrated. Cold brings droughts on the prairies.
