Game Over for the Climate?

Is it 'game over' for the climate? Eminent Arctic and Ocean Physicist, Dr. Peter Wadhams, and Dr. Maria Pia Casarini discuss this matter with host Stuart Scott, at COP-22 in Marrakesh.

Churchill said it about Americans, but you can paraphrase it- 'People can always be counted on to do the right thing- once they have exhausted every alternative.'

It has been "checkmate in three" for a decade or more. Put simply, we are too intransigent to prevent the crisis from overwhelming us. There is not enough altruism in us to sacrifice every power-hungry comfort for the sake of future generations.

Also Harvard just released a video saying that the nutrients that are in our foods also go way down not just the yield

Every aspect of Guy McPherson predictions seem to be on track. He is one year early regarding when the global catastrophic agricultural collapse will take place. One or two years off either next summer or the one after. If... we had been using the vast amounts of money to fund the pentagon etc. To research and implement CO2 extraction and capture technology as well as a vast multinational cooperative desalination plants for all places that need them. If we had started these projects 15 years ago then by now we could look forward to a merely uncomfortable future. As it is we are looking at actual extinction.

One of the major problems relating to climate change and the limits to growth is increasing and over population. Given the Catholic Church's attitude to contraception it is strange the you would say the Pope, who is the leader of the Catholic Church should be nominated for the Nobel Prize when his organisation is a major stumbling block in ensuring population does not grow much more than it need to.

Well....Here we are 3 years later.. let's see... What's changed?

GREAT VIDEO AND HEROIC EFFORT FOR EXPOSING THE TRUTH

[alanjones]

There is a new phenomenon called Wrap Around bushfires where they begin in say August / September burn into late spring / early summer and continue unabated until the end of summer. Australia is the first country to experience this phenomenon.

I've always assumed that I'd be dead by 2050 or close it. Now I read about methane release in the Arctic Ocean and if I make 2025 I think I'll be one of very few 'lucky' ones
These models do not factor in methane release

I certainly don't want a 4C temperature increase.  Even in England our summers are too hot and long now whilst our other seasons are now too mild and miserable.  The way I see it, those RCPs now mean the difference between climate chaos and climate devastation.

In 2000, I noted a 45% decline in Arctic sea ice volume from 1979 to 1998 in the US Navy data. Simple extrapolation indicated an ice free summer by 2020. We are not quite there, but we are close.
I figured in 2000, that an ice free Arctic would mean above freezing temps going over Greenland, melting the ice.
This accelerated melt pattern I called hyper-melt mode.
When this happens, we can expect, IMO, for ocean rise to accelerate dramatically. Initially, it will rise by centimeters/year.
But, in a decade or two, I would expect the warming of the shallow Arctic Sea, to melt Greenland so fast, that the
ocean will start rising by inches/year.
That is, I expect the oceans to rise by feet per decade, and by many meters per century.
The problem with most climatological analyses, is that they tend to look at only one or two factors at a time.
They will say "assuming everything else stays the same, these factors will cause X to happen.
BUT, nothing stays fixed. Everything is interconnected. There are many positive feedback loops that are also interconnected.
So, I think Global Warming's acceleration will itself, accelerate.
Like accelerating your car going downhill, things can get out of control very quickly.

Just yesterday on the public news, the discussion of geo engineering was beginning to be discussed out in the open. That should alert all, even the deniers, that we are in deep trouble, and we are working on a way to do business as usual any way possible and at any cost, to the detriment of all life. Geoengineering plus BAU is irresponsibility on a grand scale.

[robertpoen]

We need massive reforestation, restoration of carbon sinks, already proven to remove CO2 from atmosphere, at least until other safe methods are found.

[jimsanders]

Face the fact ! My children, and grand children are among the walking dead without change "NOW"!

[georgspengler]

We will not leave the fossil fuels in the ground. We are too greedy.
Today there are 2 power plants that use carbon capture and storage and it works. Investments in this technology are as important as investment in renewable energy.

The way things are going the future looks like being something like the Hunger Games.

[antred]

A point that needs to be made often is that while X degrees of warming may not sound particularly scary, we have to take into account that that is an AVERAGE over an entire year. Meaning even if global average temperatures increase by 2°C, you may have extreme outliers where a heat wave is 8°C hotter for a few days than it would otherwise have been, or a cold wave that is 10°C colder than it would otherwise have been. A few such events every other year or so, and you can say goodbye to much of the world's food supply, not to mention that such extreme conditions would probably outright kill many people.

And also rivers more moisture in the atmosphere bigger rain storm just started happening rivers are flooding all kinds of towns all the towns are by rivers

We are frogs in the pot of water that is slowly boiling, the thing is even if the frog could turn off the stove the ​burner does not immediately cool and neither does the water.
