It is because of the tipping points and feedback loops involved with reaching 1.5 degrees C global warming.

It was at least that warm or warmer early in the interglacial period, but nothing terrible happened.

I have seen the claims of tipping points and feedback loops for years now, they are dumb today as they were 25 years ago.

Which is why you can't post any evidence that the specific tipping points referred to by Greta Thunberg are invalid.

Do you actually believe what you post? Or are you simply trying to deceive people?

Exactly!!!
And that's why we need to waste...err...invest trillions in less reliable, "green energy".

Interesting tangent. I have a number of questions and comments on that. A few:

1. The Antarctic Coast has the windiest regions on the planet - this is huge potential energy source - why isn't it being utilized more?

2. Why are there so few partly underground homes which lower the need for heating and cooling. Ever visited a cave during winter cold or summer heat?

3. Why are so many roofs dark colored instead of white - an easy way to slow global warming by reflecting solar energy back into space.

4. Related to that, why so few 'green roofs' where residents can grow food and flowers on their roofs?

5. Why so few cross-continent man-made rivers to alleviate flooding and drought? These could be partly underground btw.

Bottom line - we have the technology to solve most problems (not Corona virus however). The real problem is earth's moral breakdown including greed and lack of love.

1) Did you account for the cost of installing transmission lines to South America, and the sheer distance it requires?

2) There are so few because people are unaware, even those ecoloonies never seem to notice it. I have been in one, my own Uncle in Colorado (west side) had one built to specification. He was a 40 year Biologist veteran.

3) The savings is minor for the trouble.

4) Flat roofs are a bad idea in most parts of the world. When I was working, I had to help clean up, drain and repair a flat roof a large public Library, in a dry climate it was still hard to prevent flooding and leaks. Two different years there were over 6" deep of water on the flat roof! My brother had a house where part of the roof was flat, this is SEATTLE! He had to make numerous repairs to stop the leaks, with a LOT of tar used there, I helped him one year (1983) he finally gave up and moved far away to a hot city, one of the hottest in California.

5) Waaay too expensive, a lot of the floods are CAUSED by our use of the rivers in the first place, we try hard to PREVENT flooding, thus reduced its ability to shed excessive water when it is needed, instead we try to force all the water into the rivers themselves, thus is fails over and over.

Ah, yes - economic interests often outweigh the interests of those of us who love our planet and treat it as a sacred gift from God.

Ah yes another counterpoint free reply, it is clear you have no answers to my reply, some which actually supports the environment, especially #3 and #5.

Cheers.

Introduction:

"

Global warming is the ongoing rise of the average temperature of the Earth's climate system and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.[1] It is a major aspect of climate change which, in addition to rising global surface temperatures,[2] also includes its effects, such as changes in precipitation.[3] While there have been prehistoric periods of global warming,[4] observed changes since the mid-20th century have been unprecedented in rate and scale.[5]


Observed temperature from NASA[6] vs the 1850–1900 average used by the IPCC as a pre-industrial baseline.[7] The primary driver for increased global temperatures in the industrial era is human activity, with natural forces adding variability.[8]
The Intergovernmental Panel on Climate Change (IPCC) concluded that "human influence on climate has been the dominant cause of observed warming since the mid-20th century".[9] These findings have been recognized by the national science academies of major nations and are not disputed by any scientific body of national or international standing.[10] The largest human influence has been the emission of greenhouse gases, with over 90% of the impact from carbon dioxide and methane.[11] Fossil fuel burning is the principal source of these gases, with agricultural emissions and deforestation also playing significant roles.[12] Climate sensitivity to these gases is impacted by feedbacks, such as loss of snow cover, increased water vapour, and melting permafrost.[13]."

Another cut and paste exercise, doesn't know how to articulate what you are thinking.

Greta doesn't know what science is, she just parrots what others tell her to say. The girl is being used at her personal expense for propaganda purposes, you are favoring this abuse.

The Ugly One didn't finish high school ... Newtonian is quoting a high school drop out? ...

The appalling thing about Newtonian's rhetoric is that there is currently 1.6 billion fellow humans who have to cook every meal by burning wood ... and that these folks have to send their children out everyday all day long to collect firewood ... sun-up to sun-down ... it's a miserable existence ... yet here we have Mr Newtonian advocating that these 20% of all people go without forevermore ... cutting fossil fuel burning by half means these people never get electricity for their stoves or refrigerators ...

what would Jesus say about that? ...
 
WATCHTOWER.ORG is a Jehovah Witness publication...

I think I am seeing the link (or lack there of) to critical thinking skills.

I wasnt aware that Gretta was a JW.

observed changes since the mid-20th century have been unprecedented in rate and scale.

So? Unobserved changes have been much larger in rate and scale.

You still haven't said, how many nuke plants should we build?
 
... I never posted global warming in earth's main problem ...

Yes ... you did ... post #57 ... you very explicitly said loss of biodiversity these past 100 years will be caused by global warming over the next 100 years ...

You posted a list of 37 things caused by climate change, now you're saying you didn't post that ... see how foolish you sound? ...

... or are you just apeing a teen-age little girl? ...
 
It has been proven that our earth was once covered in ice sheets. For the past several thousand years this ice cap has been melting. We can now find towns along the coastline that are now under water. The global sea level is rising. I would try to calculate the eventual sea level once the remaining ice cap and glaciers melt but don’t have the technical knowhow to do it but I do believe New York will someday be under water which is proof climate change is occurring and it will have a dramatic effect on human existence.

Burning fossil fuels is making our weather worse right now,” with greater likelihood of deadly heat waves, wildfires, droughts and floods
Fossil fuels are finite. If we continue to use fossil fuels at this rate, we will consume all known fossil fuel reserves in 30-40 years. Once we consume it all the earth will gradually return to its previous state and the world will continue to evolve as it should.

Or so it is as I see it :)-

How many new reserves will we discover in 30-40 years?

Actually we will stop the mass use of oil long before it runs out, it is the economics that will eventually make it too expensive to explore and drill anymore.

The previous state was a short lifespan, dawn to dusk work on small family farms, subject to the ravages of disease, with whole sale destruction of natural resources.

YOU can leave the oil based life, go buy a 10 acre place and live the Amish......
 
It is because of the tipping points and feedback loops involved with reaching 1.5 degrees C global warming.

Which tipping point? ... what feedback loop? ... these things violate the laws of thermodynamics unless you can explain how they don't ... the main feedback loop here is clouds will be increasing which lowers temperatures, but this is a negative feedback ... reducing temperatures as time goes forward ... look at the ice core data ... why didn't these "tipping points" happen during previous inter-glaciations? ... what magic are you relying on with your claim? ...

You didn't say how this changes climate either ...
For example:
" 10. One of the most striking quantitative findings concerns the loss of biodiversity. It predicts the proportion of species that will lose half their geographic range. Out of 105,000 species studied, the rate doubles between 1.5C and 2C warming to 16% for plants and 8% for vertebrates, and triples to 18% for insects."

We can go through each of these 37 weasel statements if you'd like ... but you just copy/pasted one:

The main cause for species loss is habitat destruction ... cutting down a forest and planting corn ... and we are over-fishing our oceans ... and these are accelerated by increasing human populations ... global warming will only have a trivial effect on species loss as long as we continue farming and fishing ... more people to feed means more loss of species ...

Ever notice the great mega-fauna extinction events in the past 50,000 years were coincident with the arrival of humans? ... famously here in North America 15,000 years ago, but also Australia 40,000 years ago ... many many species have gone extinct long before industrial times ...

Sounds like you're okay with clear-cutting the rain forests, dumping toxic waste in our rivers and stripping the oceans of all life forms larger than a rat ... in your claim above, you say it's only the warming that's bad, everything else is fine ...

How many species are thriving behind human's destructiveness ... lampreys, coyotes, coronaviruses, Johnson grass, zebra mussels ... the list goes on ... plus the warmer temperatures and more abundant CO2 will benefit plants in general, and benefit human food plants specifically ... especially since rainfall will increase and be more evenly distributed ... slight increases in temperature means slight increases in rain, not near enough to solve our water problems or counter-act human procreation ...

Human population quadrupled in just the last 100 years ... it will not quadruple in the next 100 years ... if population only doubles, we still have negative outcomes for 16 billion people ... all this death and misery from causes completely unrelated to global warming ...

"A Bengal tiger. Global warming puts more species at risk of habitat loss and extinction"

Falsehood ... human predation and clearing the forests is what's killing off all the tigers, not global warming ... and of the panthers; lions, tigers and jaguars are in trouble; but leopards are growing in population and expanding their ranges ... ecological niches don't stay empty for long ...

Habitat destruction is linked to point 10 - the loss of biodiversity. I never posted global warming in earth's main problem. If you actually looked at the links to our literature on this you would have realized I believe global warming is just one of many serious ways man is ruining the earth.

You are partly correct and partly in error. Both flooding and drought (including wildfires) are on the increase due to global warming - obviously not in the same place at the same time.

There are many man-caused problems - here are a few that you posted about>

1. Overpopulation - though this is really only a problem because of the activities of said population. I could go into detail on that if you would like me to.

2. Habitat destruction. But global warming is one way habitats are being destroyed by man. Other ways include use of pesticides and herbicides in farming, and the failure to contain fertilizers on farmland. For example, huge dead zones in the Gulf of Mexico are caused by this.

Growing one crop also causes lack of biodiversity - not to mention other problems.

Slash and burn does not just add CO2 - it destroys whole ecosystems! Worse that clear-cutting though that is a problem as well. There are advantages to having a reasonable amount of old-growth forests.

3. Over fishing and human predation. Certainly another problem. There are actually health advantages to eating less meat (and fish) and more vegetation. Just having a few hundred types of fruits and vegetables is a related problem. There is an enormous amount of variety in edible plants. Two examples: the common violet (NOT the African violet) and common chickweed.

The more the variety of plants grown for food the more biodiversity. However, organic gardening is required.

Well, the list could go on - I will start a thread on the many ways man is ruining the earth. I have been posting on the subject of global warming because of the lies and deceptions about this being posted on this forum.

Are there threads on biodiversity, deforestation, over fishing, air pollution, water pollution, ocean pollution, loss of top soil, poisons in foods and food containers, thawing of pathogens due to the thawing of the arctic permafrost, hunting (especially for sport or poaching), fences, oil/petroleum produce pollution (e.g. oil spills, pipeline leaks, etc.)?

If you post a URL for a thread in this forum on any of these subjects or on any subject involving the environment - I will try to post on it.
I will certainly try to post on them.

Both flooding and drought (including wildfires) are on the increase due to global warming

Sounds awful!!

What is the optimum temperature.....to minimize flooding and droughts? Link?

Obviously the way we were when droughts and floods were less severe.


Article December 2018:

" While much climate research relies on complex models to make projections, this new work interprets already-observed monthly rainfall data from 50,000 weather stations around the world. “That’s not to say models are not good,” Dr. Lehmann said in an interview, but his observational data “fits what we expect from physics and what models also show.” "

"Stephanie C. Herring, a climate scientist with the National Oceanic and Atmospheric Administration and an author of the report, said that, over the years, the attribution work has helped to establish the present-day effects of climate change.

“We’re taking out that factor of ‘climate change might impact us someday,’ ” she said. “Climate change is impacting us now.”

The message of the studies is “painfully clear,” said Heidi Cullen, a climate scientist with the Monterey Bay Aquarium Research Institute. “Burning fossil fuels is making our weather worse right now,” with greater likelihood of deadly heat waves, wildfires, droughts and floods, she said. “And the more we burn coal, oil and gas, the worse it will get.”

" More records for both wet and dry weather are being set around the globe, often with disastrous consequences for the people facing such extremes, according to a study published Wednesday that offered new evidence of climate change’s impacts in the here and now. ..."

Obviously the way we were when droughts and floods were less severe.

When was that? What was the optimum temperature? Link?

“Burning fossil fuels is making our weather worse right now,” with greater likelihood of deadly heat waves, wildfires, droughts and floods, she said.

Baloney.
I have been giving links - you either do not believe the sources I am quoting or have not read the scientific
articles. Does Greta Thunberg's reference to 1.5 degrees C global warming since before the industrial revolution ring a bell?

I have been giving links

Yeah, that opinion piece from the New York Times was very impressive!!!

Didn't answer my questions though. Try again.

Does Greta Thunberg's reference to 1.5 degrees C global warming since before the industrial revolution ring a bell?

Yes, her whining rings a bell. So what?

This dude is a cut and paste artist, but can't write a post in his own words, he thinks people are going to read a bunch of links over and over, yet can't summarize his posts at all.

He is also smitten with a kid who has no original thought in her head about global warming, she is a parrot and a hypocrite, but he doesn't see it at all.



Greta Thunberg wants the whole world to think that she cares about the environment because she traveled across the Atlantic ocean by boat instead of by airplane.

However, in the real world, multiple yacht crew members flew on an airplane from Europe to New York in order to bring the yacht back to Europe.

Furthermore, the yacht itself was made from propane and petroleum – the very same things that Thunberg was protesting against.

How many new reserves will we discover in 30-40 years?
none


Ever since we started using oil in the 19th century, they have repeatedly said that we would run out "in 20 years."

I once read an article with a list of such predictions over the past 150 years, but I can't find it.

Scarcity leads to higher prices. Higher prices encourage conservation, substitution, innovation, and searches for new supplies.

The stone age did not end because we ran out of stones. It ended because something better came along.

If today's doomsayers had been alive in the 17th century, they would have said, "We must conserve the world's supply of candle wax, or else the people of the 21st century won't be able to light their homes at night."
 
Here's an analogy to why we'll never run out of oil.

Imagine that you are in a room which is 10 feet by 10 feet.

The room is filled 3 feet deep with peanuts inside their shells.

Every day, you spend 15 minutes in the room, eating as many peanuts as you can, and dropping the empty shells on the floor.

Question: How long will it take for you to eat all the peanuts?

Answer: It will take forever, because you will never be able to find the last peanut.
 
Wow. Of course, that means your functionally out of peanuts quite some time prior. When it costs a few thousands dollars to locate and extract each barrel of oil, no one is going to be burning it in their 400 hp V-8s to haul 2 tons of Detroit iron around the countryside.
