The Germans are decimating the black forest to throw up wind mills
To protect the earth...

If so, that emphasizes how retarded the climate brigade are.

Three years left to limit warming to 1.5C, top scientists warn

The Earth could be doomed to breach a key climate target in as little as three years, scientists warn.

www.bbc.co.uk

The Earth could be doomed to breach the symbolic 1.5C warming limit in as little as three years at current levels of carbon dioxide emissions.

That's the stark warning from more than 60 of the world's leading climate scientists in the most up-to-date assessment of the state of global warming.

Nearly 200 countries agreed to try to limit global temperature rises to 1.5C above levels of the late 1800s in a landmark agreement in 2015, with the aim of avoiding some of the worst impacts of climate change.

But countries have continued to burn record amounts of coal, oil and gas and chop down carbon-rich forests - leaving that international goal in peril.

It's summer, so here's the latest climate prediction.

I wonder what the dinosaurs would think of our very low heat and co2 levels

Its true that hundreds of millions of years ago CO2 and heat were higher, but that is irrelevant since we are not dinosaurs, and we would have to move out of all the coastal areas that will become flooded.
The sky is also perpetual clouds when more CO2 makes it hotter.
No more astronomy.
Aviation much more difficult.

 

[Rigby5]

Climate predictors are on a BLUTARSKY (zero point zero) -- 0 for the last 100 years. But, they never stop predicting or trying to take away our freedoms.

Wrong.
Climate predictions have always been accurate.
The proof is the Northwest Passage that did not exist for tens of thousands of years, suddenly opened in 1997.

Wasting fossil fuel is not a freedom, but harming others.
Doubling the CO2 in the atmosphere is not a right.

 

[Rigby5]

Only if you ignore natural warming that occurs in every interglacial period and believe the feedback (i.e. water vapor) is 3.5 times worse than the instantaneous GHG effect of CO2 which is only 1C per doubling of CO2.

I disagree.

The natural warming/cooling is a 110k year long cycle that we have compressed into less than 500 years.
We also are adding an artificial warming right on top of the warmest part of the natural cycle.

We don't know when this current warming will stop as heat is going to keep accumulating for a very long time, even if we were to stop adding more CO2.
It could be like Venus where the global warming keeps it over 400 degrees.

And forget about water vapor.
First of all, heat retention at the surface is irrelevant.
It only counts on the boundary to space.
That is where the solar energy has to leave the planet, and can't if blocked by CO2.
Only infrared photons can leave through the vacuum of space, and CO2 blocks infrared.
And there is no water vapor at the boundary to space since it is so cold that it precipitates out.
Water vapor has the opposite effect of cooling the planet by reflecting incoming solar energy, by increased albedo.

 

[Rigby5]

LOL, we reached that level a year ago already yet the ecoloonies haven't noticed the doom that fell on us.......

Media Reports Earth’s ‘1.5C Temperature limit’ was ‘breached for 12 months in a row’ – Nothing Bad Happened​

It can take hundreds of years for solar energy accumulation to reach its peak.
And if that peak is fatal to all life on the planet, it is too late to stop it.

 

[Rigby5]

It's been warmer in the past and none of this doom and gloom happened ... oh, except we invented agriculture when it was warmer ... that's a bad thing, right? ...

Wrong.
The only time it was warmer was when there were only dinosaurs and no humans.
It is now warmer than it has ever been for humans.

What climate expert are you parroting?

Or are you the expert yourself?

I'm no expert myself but I suspect you trying to concoct a misleading denialist position by making water vapour the demon?

I think we're going to have to start looking more closely at the effects of climate change that we've all seen happening.

Then we could ask the denialist's most educated and trusted expert if she considers it to AGW?

What do you think?

Are religious superstitious beliefs clouding your judgment? Do you believe that only the god has the power to influence the earth's climate?

 

[Rigby5]

With regard to the planet's climate, you can consider me your god.

To answer your questions, let's look at the evidence. You like evidence, right? Do you need for me to walk you through what this evidence shows?

Wrong.
There have been over 12 normal ice age and warming cycles.
But they are over 110k years long, and we have compressed a new artificial cycle down to only about 500 years, so have accelerated the natural cycle by over 2000 times faster.
That does not allow for adaptation.

Really. You don't say.

What about the GLOBAL COOLING that was predicted int the 1970's?

Driving my car, even if it sends CO2 into the air, IS MY RIGHT and you can have my car when you pry it from my cold dead hands, lefty.

I also will not give my right to get on an airplane even it it spews CO2 into the air.

Or to run my air conditioner.

Hope you understand, we aren't giving up our freedoms to big world nanny state government.

Not without the fight of your life.

My apologies ... I was speaking of the beginning of the Holocene ... roughly 10,000 years ago ... temperatures were 4ºC over 20th Century average ... and sea levels were 30 feet higher ...

Go back to post #6 ... are you going to back any of that up or are you just here flinging poop? ...

Wrong.
It is much hotter now than the Holocene.
The Holocene was peak of the natural warming/cooling cycle, and ended the last ice age.
It was about 10,000 years ago
But we are making it much hotter now than it was then.
And the problem is that by doubling the CO2 concentration, we are making the planet collect heat.
But we don't know how much it will keep collecting?
It is possible that the amount of CO2 we added will collect so much heat that all life on the planet will die.

 

[Rigby5]

There are cities in China that emit more CO2 than entire countries, go chain yourself to the Chinese Embassy

The US emits 5 times more CO2 per person than China does.

I see that Post #9 was too difficult for climate cultists to handle thus stay away, here is more bad news to show more evidence that we have already arrived at the made up doom 1.5C increase line and nothing terrible showed up.

Where is the Kaboom???

Land temperatures have already risen more than the dreaded 2°C, with no cataclysmic consequences … there has been no historical “climate emergency” despite temperature increases.

View attachment 1130151
And Berkeley Earth global temperature is already above the dreaded 1.5°C threshold.

View attachment 1130152
Paleo data shows that over the Holocene temperatures have varied widely with little change in CO2, and the current warming started in 1700, long before the modern CO2 increase.

Where is that gosh darned KABOOM!!!

Wrong.
The CO2 does not immediately cause problems.
The CO2 causes solar energy to accumulate and not be able to leave the planet.
There is no end to that necessarily.
If it continues to accumulate and reaches 400 degrees like it does on Venus, then all life on the planet dies.

 

[CrusaderFrank]

Fake, irrelevant CCP Propaganda. That's the tell that the Climate Cult is just shilling for the CCP and trying to drag down the US economy

China emits 4 times the CO2 per person of India

 

[Rigby5]

The only actual "warming" in the data is from

URBAN HEAT ISLAND EFFECT

there is no other warming at all

NO WARMING in the ATMOSPHERE
NO WARMING in the OCEANS
NO ONGOING NET ICE MELT
NO BREAKOUT in CANE ACTIVITY
NO OCEAN RISE

Wrong.
No one uses urban thermometers to measure global temperature.
They use ocean temperatures and satellites.

Everyone has measured the atmosphere and ocean warming, and the glaciers are all obviously melting, disappearing, etc.
The oceans are inches higher.

But the problem is that since CO2 causes heat to not be able to leave the planet, it will accelerate.
It's not linear, but exponential.

{...
Curry has become known for hosting a blog which is part of the climate change denial blogosphere. Social scientists who have studied Curry's position on climate change have described it as "neo-skepticism", in that her current position includes certain features of denialism; on the one hand, she accepts that the planet is warming, that human-generated greenhouse gases like carbon dioxide cause warming, and that the plausible worst-case scenario is potentially catastrophic, but on the other hand she also proposes that the rate of warming is slower than climate models have projected, emphasizes her evaluation of the uncertainty in the climate projection models, and questions whether climate change mitigation is affordable.
Despite the broad consensus among climate scientists that climate change requires urgent action, in 2013 Curry testified to the United States Congress that, in her opinion, there is so much uncertainty about natural climate variation that trying to reduce emissions may be pointless.<a href="Judith Curry - Wikipedia"><span>[</span>5<span>]</span></a>
...}

While it is true that predicting long range results of doubling the CO2 is difficult, the reality is that we have measured a very unusual increase in global temperatures, glacier melt off, ocean rising, etc., and that the risk is not worth it.
We are running out of fossil fuel anyway, so there is no reason to take the risk.
The sooner we switch to nuclear, solar, wind, bio energy, etc. the better.

You do not know what they meant by "global cooling" in the 1970s.
What they meant is that there is a 110k long natural warming/cooling cycle, and the warmest part of that cycle was around 15k years ago.
So now the normal cycle should be cooling.
But so slowly no one would notice.

The current artificial warming cycle is over 2000 times faster than normal, and has no upper limit.
We don't know how hot it will make things, and this new artificial warming is on top of the hottest part of the natural cycle.
