Change over time

More than 90 percent of the warming that has happened on Earth over the past 50 years has occurred in the ocean. Recent studies estimate that warming of the upper oceans accounts for about 63 percent of the total increase in the amount of stored heat in the climate system from 1971 to 2010, and warming from 700 meters down to the ocean floor adds about another 30 percent.

Annual ocean heat content compared to the 1993 average from 1993-2019, based on multiple data sets: surface to depths of 700 meters (2,300 feet) in shades of red, orange, and yellow; from 700-2,000 meters (6,650 feet) in shades of green and blue; and below 6,650 feet (2,000 meters) as a gray wedge. Graph by NOAA Climate.gov, adapted from Figure 3.6 in State of the Climate in 2019. See original figure for details about data sources and uncertainty.

Less than a watt per square meter might seem like a small change, but multiplied by the surface area of the ocean (more than 360 million square kilometers), that translates into an enormous global energy imbalance. It means that while the atmosphere has been spared from the full extent of global warming for now, heat already stored in the ocean will eventually be released, committing Earth to additional warming in the future.

And just why does anyone want to go back to a mile high layer of ice over Canada just so we have 180 ppm CO2.

Wouldn't hurt to entertain the thought that the current interglacial period was scheduledby Mother Nature alone.

Summarized as a 5th glaciation period (on Mother Natures schedule ...alone) will have longer lasting and more consequential changes than global warming caused partially human releasing of stored carbon.

At least consider the thought.

Models that account only for the effects of natural processes are not able to explain the warming observed over the past century. Models that also account for the greenhouse gases emitted by humans are able to explain this warming.

All the problems you listed are important environmental problems as well. But why ignore what scientists are saying about the impact climate change will have on the earth and many of those problems? Its the mother of all environmental problems.

You missed the point that CO2 has gone up rapidly from human causes.

Chuck no one is looking at the whole history they are picking numbers for the cause because that's who pays the bills. It's the cause that spending billions on these charts and graphs and it's not science.

You cant figure that out yet. Wow is all I have to say.

Maybe read with an open mind ( tough for die-hard believers)

FAKE INVISIBLE CATASTROPHES AND THREATS OF DOOM.

See in my example the polar bears are dying, show a sick old bear on its last days so all the bleeding hearts fall down and cry. The reality is no one who is crying will actually ever see a real polar bear in the wild only one in a Zoo till they shut all those down. So it's easy to do the old sleight of hand.

Same with the sea ice in the ARtic. Who will ever travel to the North pole. Not many and guess what the MSM can print or televise anything and the sheep believe.

HEll Trudeau is Santa Clause to Some in Toronto it's working.

Charts are fun to paste but maybe look a little deeper.

dml, I followed your link. It was wikipedia, not a respected scientific organization, Chuck will be along shortly to discipline you.

But at least wikipedia does provide links to the sources. The impossible claim of 100 ppm supposedly comes from this paper.
https://web.archive.org/web/20190927033455/http://droyer.web.wesleyan.edu/PhanCO2%28GCA%29.pdf https://web.archive.org/web/20190927033455/http://droyer.web.wesleyan.edu/PhanCO2%28GCA%29.pdf
For some reason only available through the wayback machine.
Which makes no mention of 100 ppm during the miocene. Neither do any of the other links attached to that reference.
The paper does say repeatedly that

, all cool events are associated with CO2 levels below 1000 ppm. A CO2 threshold of below 500 ppm is
suggested for the initiation of widespread, continental glaciations,

We are below 500, way below 1000. And we are cold, bouncing along the bottom of the range, stuck in a glacial epoch.
Unless you can find the source of the 100 ppm claim, Perhaps you should suggest an edit to Wikipedia.

The miocene was full of mammals (including our direct ancestors) and plants that we would recognize. How could they possibly have survivived through 100 ppm?
And no, the continents were not in significantly different positions 23 million years. About the only big change since then was the closing of the panama isthmus

Oh, oh chuck
God damn Details again

I’ll say it again co2 is not the problem, it’s been way higher or lower throughout the history of the world. The point is the world has managed just fine to adjust.

The issue with man is we pollute the oceans, cut down forests, etc. Think people, the carbon sink just can’t keep up, how much of it has been chopped down, roads and cities using up area that was once part of that sink. Oceans have massive plastic islands as well as pollutants vastly reducing the ability of phytoplankton to do its job of absorbing carbon dioxide (probably the biggest sink).

Yes man is impacting the world in a negative way but IMO it’s not co2 that’s the real enemy. When modern man leaves the planet the earth will probably breathe a huge sigh of relief.

Hurry up Elon, herd them on board, Mars here they come.

Absolutely true
Cities are the problem and they lecture us
We need to work on the problems we can see like water pollution
Air pollution in cities etc

You can see shrinking glaciers! David Schindler was very clear about the impact losing glaciers will have on fresh water.

"But this way of thinking about Canada’s freshwater is misleading, Schindler said, because what sustains that water supply is runoff. With climate change already affecting Canada’s glaciers and increasing incidents of drought, our freshwater supply is in danger.

“You can’t talk about water without talking about climate change,” Schindler said. “We know that the snow packs in these mountain ranges are dwindling as last winter gave us a good example of. The glaciers supply a tiny amount of the total annual flow of a river but it comes at a critical time of the hot, dry summer.”

Schindler said the Bow River Glacier can supply up to 50 per cent of the river’s water during dry spells. But he said, over the last century, the Bow River Glacier has dramatically retreated threatening water supply for cities like Calgary as well as the cold water necessary to sustain the river’s famous cold water fish species during the hotter months of July to September.

Think for yourself instead of cut and paste we would maybe believe you if you show your reasoning.

Good thing the Forests were saturated last year in most of western Canada with an abundance of rainfall . Rivers and lakes at highest levels in decades

Glaciations occurred even during the Miocene era.

"In South America at latitude 47°S, till was deposited sometime between 7 m.y. and 4.6 m.y. ago, at a time when the local climate was colder than today's. During this same interval glaciers extended to sea level in southeast Alaska, and widespread cooling of the ocean surface in middle latitudes, worldwide marine regression and change in the oxygen isotopic composition of ocean water occurred..."

During the late Miocene epoch, about seven million years ago, large areas of the continents experienced drying, enhanced seasonality, and a restructuring of terrestrial plant and animal communities. These changes are seen throughout the subtropics, but have typically been attributed to regional tectonic forcing. Here we present a set of globally distributed sea surface temperature records spanning the past 12 million years based on the alkenone unsaturation method. We find that a sustained late Miocene cooling occurred synchronously in both hemispheres, and culminated with ocean temperatures dipping to near-modern values between about 7 and 5.4 million years ago. The period of maximum cooling coincides with evidence for transient glaciations in the Northern Hemisphere and with a steepening of the pole-to-equator temperature gradient, as well. We thus infer that late Miocene aridity and terrestrial ecosystem changes occurred in a global context of increasing meridional temperature gradients. We conclude that a global forcing mechanism, such as the previously hypothesized decline in atmospheric CO2 levels between eight and six million years ago, is required to explain the late Miocene changes in temperature, climate and ecosystems.

AF5, if instead of pulling out just point I made about continental drift, you would have included the next sentence about earth being a molten mass you would have realized I was referring to other factors that influence climate, and not stating that continents were in a different position during the miocene era which of course they were not! Although it is during that era when the Himalayas were created if you are interested as a result of the Indian subcontinent pushing northward.

But that is okay, anything to deflect the conversation away from the original point of my posts on this site, that 415 ppm currently is higher than the 300 ppm that was the maximum measured level of CO2 in the last 800,000 years, and that current levels are not the lowest in the history of the world as Saskfarmer claimed in the very first post. Math must be hard!

And by distracting you do not have to come up with any reasons why this sudden increase in CO2 has happened or what the impact on climate this may have. We know it is better for plants, but only if plants have everything else they need to support more growth such as precipitation.
