And I responded with the available data, did I not? There didn't need to be a civilization of 7 billion people "all living on a knifes edge". It doesn't matter if there was 7 billion or just 7, they were all living on the same planet we are, but with no technology at 22C hotter and 5500 ppm more CO2. Somehow they survived without AC. Changing climate has been a natural driver of evolution. We evolved when it was 22C hotter with 5500 ppm more CO2. As for extinction events, there have been no extinction events because the Earth went up 22C. The extinction events came from extreme cold during the ice ages. There is no doubt that the Earth's climate changes. It's been swinging between ice cube and sauna for the life of the planet itself. That doesn't make AGW actual science. You have no idea what our rates of extinction are compared to the Permo Triassic, as you have no idea how many species of creature existed at that time to compare to now. Actually, the rainfall study I linked you to is all computer models, since many countries on Earth don't even take measurements. If they do, their accuracy is often in question.
The above is complete garbage. BTW computer output predictions for the future are NOT data. Who has said that CO2 does not affect global warming ?? But the natural history record shows no correlation between CO2 and global temperature.
Name some. The oceans will always be basic (pH > 7) due to the chemistry of the oceans. Coral reefs are doing just fine.
Oceans have historically had a ph of 8.2 and has dropped to 8.1. A basic concept in science is that everything is relative. That is, even though the ocean is alkaline, it is becoming more acidic. Coral reefs are not doing fine.
When the pH of an alkaline solution is reduced it becomes less alkaline. Sure they are. The claim that coral reefs are being decimated by CO2 reacting with water to form carbonic acid is false.
I don't mean to be a stickler, but I find the the term acidification a bit misleading. The oceans are quite alkaline. however, they are becoming less so. However, everything being relative, a creature living in an environment, of say a ph of 9 and it drops to 8, that creature experiences an acidic effect. A couple of extra ions to tug at its structure.
That’s ridiculous. What is the 24 hour variation in pH of sea water ?? The notion that minuscule increases in average pH would destroy coral reefs is absurd.
"When conditions such as the temperature change, corals expel the symbiotic algae living in their tissues, responsible for their colour. A spike of 1–2°C in ocean temperatures sustained over several weeks can lead to bleaching, turning corals white. If corals are bleached for prolonged periods, they eventually die. Coral bleaching events often lead to the death of large amounts of corals. Reefs around the world have suffered from mass bleaching events for three consecutive years. Iconic reefs such as the Great Barrier Reef in Australia and the Northwestern Hawaiian Islands in the United States have all experienced their worst bleaching on record with devastating effects. The bleaching of the Great Barrier Reef in 2016 and 2017, for instance, killed around 50% of its corals." https://www.iucn.org/resources/issues-briefs/coral-reefs-and-climate-change I'll spare you a lecture on how a small change in pH can change the chemistry of how invertebrates construct their shells Organisms that make shells need a stable pH in order to lay down calcium carbonate in a 3 stage reaction. As the oceans absorb CO2 and converts it to carbonic acid, even minor lowering of pH makes it harder for them to sequester the ions they need to form shells and other structures. Don't forget that pH is a base 10 exponontial scale with 7 being nuetral. So even minor changes can have dramatic effects.
On the northern Oregon coast there are lots of starfish. About five years ago they started dying off from a wasting disease, caused by a pathogen whose appearance was attributing to the warming of the Pacific ocean. However, a number of them survived and the numbers are growing. The ones that survived have a different DNA than the majority that died. Thus evolution before our eyes.
Here are some inconvenient facts: There is no historic correlation between Oceanic pH and atmospheric CO2. Oceans did not become acidic (pH < 7.0) when atmospheric levels were 15 times what they are today. The models that you refer to do not take into account the buffering actions of the oceans to prevent pH from ever becoming less that 7.0. Limestone in the oceans guarantees that the oceans cannot become acidic and nowhere near the acidity of the rain water which falls on them daily. source - "Inconvenient Facts" - Wrightstone - 2017
It's not my job to teach you basic equilibrium chemistry but I suggest you read up on the carbon cycle. Or provide proof that the oceans were no more acidic at 15 times todays concentration or that limestone is somehow buffering the formation of carbonic acid? I can't access your source as posted. Do you know how acidic the oceans were during the permo-triassic and what happened to life at that time? Any scientist reading your posts would roll their eyes and suggest you try and inform yourself through learning basic chemistry and leave the denier websites alone.
We had the same die off up here. Climate change has always been a driver of evolution. In the case of past extinction events life slowly adapted and there was an explosion of new forms over many thousands of years. This is a different type of event as it is driven by us and the explosion of human activity is driving the system way out of balance and equilibrium. Nature abhors the type of high energy system we are creating. If we are the problem, there is by no means certainty that human civilization will survive the evolutionary conditions we are creating. We may if we can adapt quickly enough but judging from the reaction on threads like this and all the other internet forums where people go to spread the anti-science garbage they pick up on line, probably we can't adapt-at least not in civilizations present form.
My source is a book. It's fully footnoted and referenced. If you are interested in the truth it is available. I have an engineering degree in Chemical Engineering. What do you claim the pH of the oceans were and what was the atmospheric CO2 concentration ??
I don't worry about the planet anymore. I know it will do just fine after we're gone. It'll take a while to undo the damage, but it will be fine.
He doesn’t deny that the globe is warming. The book has 15 pages of peer reviewed papers from NOAA, epa, Nature, doi, Oak Ridge, IPCC, National Academy of Sciences, ... etc
No, and please no more suggestions from you. We need real ideas, or it's are grand kids that we **** over. And I'm not cool with that.
It's not obvious what 99% of species dying off over the entire course of the earth's history is, when compared to human kind's tiny speck of involvement, to you? Keep reading and you'll find I had plenty to say.
The only way for the human race to truly cease killing the planet, is if the entire human species is made subject to extinction and removed from the equation. That is the only way to save the planet, kill those that are responsible for killing it. Every last man, woman, and child in existence must be wiped off the face of the planet.
