    Glaciers

    This is Athabasca Glacier in the Columbia Icefields of Banff National Park. The picture on the left was taken in 1917, while the one on the right was taken quite recently. This glacier loses 16,000,000 cubic metres of ice each year. Agriculture in southern Alberta depends largely on irrigation, and glaciers help by holding snowfall and slowly releasing it during summer months. When the glaciers disappear, river flows will be higher in the spring, but lower in later summer. This could have a significant impact on irrigation in southern Alberta. The ecology of the rivers will also be greatly affected.

      And here is the prime cause of relatively accelerated temperature increases and glacier loss. Human's emitting very large amounts of CO2 and other greenhouse gases.

      Note that the current CO2 levels are far above any of the interglacial periods during the last 800,000 years.

          Crap, Ever hear of CO2 captured in ice cores? Probably not! LOL

          https://icecores.org/about-ice-cores

          Ice cores are drilled in glaciers and on ice sheets on all of Earth's continents. Most ice cores, however, come from Antarctica and Greenland, where the longest ice cores extend to 3 kilometers—over 2 miles—or more in depth. Ice cores from the cold interior regions of polar ice sheets provide exceptionally well-preserved and detailed climate records. This is because the lack of melt at these locations does not corrupt the record of trapped gases or blur the record of other impurities. The oldest continuous ice core records extend to 130,000 years in Greenland, and 800,000 years in Antarctica.

            so that means it was a lot warmer back then before the ice built up , explain that , pure garbage is my expert opinion

              Reduced Summer River Flows

              Many summer river flows in Alberta have changed drastically over the last century, and the graphs below show various summer river flows in Alberta. The flow reduction further downstream in the South Saskatchewan river is even more severe. At Saskatoon, Saskatchewan, the flow has dropped to 20% of that at the beginning of the 20th century. Summer flows are very ecologically important, for such things as fish spawning and rearing, and riparian sustenance. They also provide water for human uses such as irrigation.

              The only way that is possible is if the glaciers were melting 5 times faster in 1910, than they are today.

              When CO2 levels were 300 PPM, the glaciers were melting so much faster that the river flow was 5 times higher in the summer, than they are today at almost 50% more CO2.

              What does that tell you about the relationship between CO2 and glaciers?

              And if the glaciers stopped melting all together, the river flows would be even lower yet.

              What year did the glaciers start melting?

                Well too bad David Schindler wasn't here to explain the the decrease in summer river flows because of declining glaciers. I am doubting he made it all up. Is that going to be your only counter argument?

                For one thing the total mass of the glaciers in 1917 was a lot more than in 2000 so that means there was a lot more ice available to melt even if the the temperatures and CO2 levels were lower.

                Plus we don't know how much more is being used for irrigation or human consumption during that period and what impact this had at Saskatoon for example.

                Summer flows are tied more closely to glaciers. Spring flows are made up mostly of snow melt.

                But your assumption that human caused climate change isn't causing the glaciers to melt more isn't suported by the science or David Schindler. The photos and the temperature records speak for themselves.

                  Yes garbage is a good way to describe your "expert" posts. LOL

                  You don't have a clue do you?

                  You thought somebody had to test CO2 in person 800,000 years ago?

                  You have never heard of ice core research and then you call research by world class scientists garbage!

                  You should join little lentil in the little flat earth club!

                    yes garbage , who cares about 800,000 year old ice ? certainaly not me , and wasting money on it is madness ,worry about whats happening here in canada and how its being destroyed by our clueless leaders , who have just insulted all jews worldwide and many more also

                      So the temperature has gone up, while the glacial melting has gone down. Both are the fault of humans and our CO2. Makes perfect sense to me.

                      So, try again, what year did the glaciers start melting, what was the CO2 level in that year?

                        So A5 why are you so obsessed with when the glaciers started melting?

                        What difference does that make when we have dramatically exceeded the previous CO2 levels through the last 800,000 years which included at least 8 ice ages and interglacial periods of warming?

                        Do you want to know when each glacier started melting in each of the 8 interglacial periods? LOL

                        CO2 levels and the glacial periods are clearly linked to CO2 levels. And prior levels during the last 800,000 years never exceed 300 ppm. Now they are around 420 and still rising along with the average global temperatures.

                        But you still deny that human caused global warming is not happening? But you have no evidence to back up your lame excuses?

                        Give up you are wasting your time and embarrassing your self again and again.

                          I am obsessed with this question because you keep presenting melting glaciers as the smoking gun evidence of man made global warming resulting from increased CO2.

                          If you want to prove your postulation, and prove the doubters wrong, the least you could do is find evidence that the glaciers were stable until CO2 hit a certain level, then their melting increased along with increasing CO2. If you could prove that, then I will take your advice and give up, apologize, and admit you are right, I am wrong.
                          Instead, you have presented evidence that their rate of melting has slowed considerably while CO2 levels have gone up. And you have obfuscated and deflected and avoided the question of when they started melting.
                          According to your reliable source, NASA, :
                          Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"

                          So if the glaciers started melting before the mid 20th century, your theory doesn't hold water.

                          So I ask again, what year did the glaciers start melting?

                            The glaciers are melting faster because of human caused warming so the science says!

                            We all know they started melting after the last ice age. Are you really this clueless?

                            Give up! LOL

                              But you just presented river flow science above indicating that glaciers are melting slower now than when CO2 was at 300PPM. Which science am I supposed to " believe"?

                              Perhaps you should leave the science to the scientists, because you keep contradicting the supposedly settled science.

                                A5 There is now less glacier ice mass left to melt resulting in lower summer flows even though the temperature is higher because of warming.

                                The lower flows are because they are shrinking! Get it? Probably not. And that's why you want to discuss when the glaciers started melting? LOL

                                Give up!
