Mr. Sailrick... Let's try to cool down and continue a scientific discussion devoid of that despicable term "denier" which you can't even define. Even if sea level is accelerating there is nothing that will stop it. Nor is there anything that can stop the natural variability from affecting the ENSO or the jet streams that create extreme weather being blamed on "global warming" from CO2 added by humans for their energy needs.

"There is, to put it another way, just the barest hint of a possibility that we could start a transition into a glacial epoch during the next century. The difference between the climate we have now and the climate we'll have as we enter a new ice age will be so small here in North America that, for the most part, you won't even notice the change."
------
Following after the Holocene Climate Optimum, the world cooled for about 6,000 years, up until the late 1800s. Since then we have warmed the planet by more than it cooled over those 6,000 years. - about 1 C warming versus ~ 0.7 cooling over those 6,000 years. Our emissions are a stronger radiative forcing than the Milankovitch cycles.

SkS Analogy 20 - The Tides of Earth

Daily tides: Controlled by daily changes in the alignment of the Earth, Moon, and the Sun.

Spring tides: Higher than daily tides, and occurring every 14 days when the gravitational forces of the Sun and the Moon are aligned.

King tides: Higher than Spring tides, and occurring once a year when the Earth is at perihelion (orbit of Earth closest to the Sun) and the moon is at perigee (orbit of Moon closest to the Earth).

Glacial “tides”1: Fluctuating sea level up to 120 m (400 ft), occurring over 100,000-year cycles and primarily influenced by the effects of Jupiter and Saturn on the orbital dynamics of the Earth.
The Sun and Moon pull on the oceans, causing bulges in their shape that cause local fluctuations of sea level.

"Jupiter and Saturn pull on the Earth, causing bulges and wobbles in Earth’s orbit around the Sun. The influence on Earth’s orbital dynamics caused by Jupiter and Saturn are called Milankovitch cycles, named after a Serbian mathematician, Milutin Milankovitch.2 Because the orbits of planets are very regular, the Milankovitch cycles cause bulges and wobbles in Earth’s orbit that operate over 20,000, 40,000, and 100,000 years. The Milankovitch cycles drive the current ice-age variations.

The direct effect of Jupiter and Saturn is to cause a 10-ppm change in CO2. The feedbacks in Earth’s climate do the rest to cause the 100-ppm CO2 change.

If planets 100’s of millions of miles away can trigger 120-m tides, is there anything that human civilization is doing today that could trigger feedbacks in our sensitive, unstable environment?

By burning fossil fuels we’ve increased CO2 by 130 ppm in 200 years, 13 times the initial CO2 pulse during an ice-age cycle."

Sailrick: "This nonsense claim was based on using 1998, which did have the strongest El Nino in a century at that time, and then picking 2008, a La Nina year as the end point, to make a completely FALSE claim."

I think you will find the 1998 "false claim" verified here: It was 1997!


And if that is not good enough you can check the Hadley ENSO data that go back to ~1880.

-----------------------
The ENSO cycle moves energy (heat) around within the planetary climate system.
Our emissions are greatly increasing the amount of energy within the climate system. Over 90% of that excess heat has gone into the oceans.
If that wasn't the case, and all that heat was in the atmosphere, we would be cooked.

You have used a false equivalency

Sailrick... The ENSO is entirely natural. There is no correlation between equatorial SSTs and atmospheric CO2 from our use of carbon for energy.

Please stop your efforts to convince all of us that there is a climate emergency because the global mean temperature has risen a very small amount. Let's accept that as a crisis in need of our attention and move on to trying to prevent it. What is your expert opinion on where we should begin?

Study after study has found that when you take out the short term variability, like ENSO, the warming trend is indisputable.

And yes that is a denier trick, focus on short term natural variability and ignore the trend. This tactic get used constantly to dis-inform people.

Second-Least-Cold Year

"Earth’s hottest year on record remains 2016, when the warming from man-made climate change combined with extra heat from the strong el Niño of that year. But even without el Niño, this year is likely to come in a strong 2nd.

Four of the five data sets have 2019 coming in 2nd place, only HadCRU has it 3rd. Four of the five adjusted data sets have 2019 coming in 1st, only NOAA puts it second."

Rick... you forgot those temperatures that were provided for 1995. But never mind.

Ok.. Rick.. Ok Rick.. Yes, the world is in big trouble because of all you have asserted. It's all the fault of humans trying to have a decent life. Everybody is is in denial. The trend is up...+0.75°C.

So.. where do YOU want to begin to stop and prevent this climate armageddon created by our added CO2 that is the waste product that plants use?

And, if temperatures rise by 18 F (10 C), the continent is doomed to be "virtually ice-free." Should the continent lose all of its ice, global sea levels will rise by nearly 200 feet (58 m)

Ohhhh Scary. "Doomed" note the word doomed above. What's your fascination with ice? You would rather have a useless continent covered with ice than covered with green plants? I think your priorities are nuts.

Lake Ontario's altitude is 257 ft above present sea level therefore in the worst case Toronto is OK and everything around lake Ontario. We're OK, don't worry about us!
Ice free Antarctica? Good news! 68 m Sea level rise? Catastrophe! This happened in other geological times, and so fast, that it was possible ascertaining event took place during northern hemisphery winter, meaning source of water was Antarctic.
This could happen again soon.
Toronto is a nice place, I had a night there in 1988, an hotel in Jarvis street, a fellow in my company told me he won't allow his sister going this street, but besides heating was all electrical, meaning probably high CO2 emissions, place was decent, even for families with kids.

Belemnite52: Could you provide a reference for those other geological times?

Prepare for the coming 1,000 years kingdom. It is not here now and we do not know when it will begin. We only know what has been revealed. The climate change will affect some and not affect others, because the unaffected ones will have indestructible bodies.

Antarctica's been frozen for 34 million years, or about 0.7% of the age of the Earth. But this entirely random event is our "ultimate heritage"? Is it any wonder so many people have stopped listening to the climate boys?

CO2 emissions by using electric heating? No not in Ontario. Most power is made by nuclear reactors and much other by hydroelectric means, e. g. Niagara Falls. No CO2 emitted n these processes, even if that was a problem and I don't believe it. (Professional Engineer. )

And new york city, a city of 8.4 million, would be under over 150 feet of water in most areas.
Couldn't happen to a nicer city. Of course there would be nobody there then, so what does it matter? Are you implying that in a thousand years the decedents of the people of New York City could not all have moved up land? If the city were not constantly rebuilt, what would be left in a thousand years anyway? I have read that the average citizen of Canada moves every 8 years. If NY were similar, this gives the constantly renewing population 125 opportunities in 1,000 years to move upland. Isn't that more than enough time? What is the problem here?

Folks, I got some really bad news for all of you. You're screwed! Read facebook.com/ron.mccune.3 and see why in about 15 years the North pole will be completely melted and about 5-10 years after that the South Pole will be completely melted as will all the Earth's glaciers and snow covered mountains. The Earth will have no more winters as insects enjoy a longer lifespan and make your lives 1000% more miserable. Global warming caused the weakest chain in the Earth's ice systems, permafrost, to for some odd reason start to melt rapidly in the early 1960's. China industrial growth, Putin's KGB minded tricks to increase warmer climates over Russia through his inaction on controlling fires in the permafrost areas and polluting the waters of Russia so that weather patterns in Russia were worsened and Putin and Russia's yearly flyover of Russia's five time zones massive amounts of military planes and equipment which yearly adds a blanket of hot air over Russia and that part of the world. Since the 1960's melted permafrost water, which now is warmer than ice, has been draining into the Arctic Ocean where it has been melting the ice in the North Pole. As that now warmer waters from the North pole circulated around the world it warmed the oceans and worse of all the waters around the South pole where it has been melting water ever since. That's how global warming started! Read facebook.com/ron.mccune.3 to see how global warming started and how to end it! But continuing as the Earth progresses from today's climate pattern of more water in the oceans creating more severe storms now and for a while in the oceans and in certain areas of the Earth most of the Earth will see drier, hotter weather with few clouds. What clouds are to be seen won't produce rain as the Earth swelters in heat from that gigantic ball of fire miles away called the Sun which is shooting hot deadly rays and pouring heat onto our planet! Fortunately since the beginning of life on Earth nature had created the one and only thing that could shield the planet from these deadly hot Sun rays and that was clouds. Clouds are Earth's umbrella from the Sun. Without clouds the Sun will bake all live from the surface of the planet. Without clouds there would be no water. Clouds are the only thing on Earth that creates water. No clouds, no life! In about 25-35 years all of you on Earth will be witnessing the end of civilization as we know it as the Sun will begin it's unchallenged task of baking the life off the face of Earth, a planet that no longer produces clouds or rain. I will say your only chance for survival is to now and especially in about 10 years to numerous times shoot somehow massive amounts of volcano ash into the sky from numerous spots on the Earth to help Earth to provide the only other thing besides clouds that can can shield the Earth from the hot rays of the Sun! Or you can all go live underground and hide from the Sun. But your water will evaporate so cover it all up! Find underground rivers! but your biggest problem will be food! There will be no way to feed everyone because you won't be able to farm anymore! That is the future all of you face in about 20 years!
People like you were saying this 20 years ago, and nothing of the sort has happened! Antarctica, together with Australia and other countries were once UNDER THE EQUATOR, so no ice then! Mass lies causing millennial hysteria are just feeding the Marxist trolls who want to bring the whole planet back to the medieval times with no industry and everybody living as hunter gatherers. Really, go see a shrink!

If this going to happen we have to build floating homes
