We all see climate change exaggeration being pushed out via the main TV news channels, but here is where a lot of these stories come from:
This is a religion in all but name and anyone who challenges it is portrayed as evil. It is the modern equivalent of tablets of stone which no one dares to challenge unless they become an outcast.
Looks like things are working again for me on my end.
ReplyDeleteClimate religion? Climatge science is based in evidence. Religion is based in faith. Which is ok that some things in life are faith based. The beauty of climate change science is that it is physics. GHGs are the basis of our earth's atmosphere able to retain heat from the sun. As we spin to the dark side (night) the earth cools. Over time there is an average temperature that the earth evens out at. That average temperature is effected by the GHGs of the earth's atmosphere. The more GHGs we add to the atmosphere, the higher the temperature we get over time from doing so.
I don't doubt that on the climate change believers side, there is exageration going on. Just as there is on the side of climate change doubters there is the story of "Its not bad, might even be good".
The IPPC defines human climate change as bad. The more we do it, the worse it gets.
I agree to the idea of that we should not make outcasts of the climate doubters. That is what a good practice of democracy does. We should be opening to listening to each other in constructive ways. That is challenging to do in our society in the world.
There is another avenue of discussion on climate in an app called quora. The cranky doubters like to erase my comments because they don't like what I have to say. Kudos to you Derrick for your skills in accepting differing opinions.
It is true that there is physics behind the science of greenhouse gases, but the way this is hyped up to make out that we face an emergency because the level of CO2 in the atmosphere is increasing is very contentious. The idea that there is an optimum temperature for the planet and just one degree increase is causing a climate catastrophe - that is where the similarity to religion comes in. Religion has often been about controlling people, here again there is a strong element of that with the climate dogma.
ReplyDeleteWIth just .5*C difference sea level rise is 8 inches higher by 2300. Economically that is trillions of dollars difference in ocean defenses around the world in construction.

The impacts of climate change at 1.5C, 2C and beyond
Carbon Brief has extracted data from around 70 peer-reviewed climate studies to show how global warming is projected to affect the world and its regions.

sea level rise 2300 at 1.5*C is 59 cm or 23 inches
at 2.0*C is 81cm or 31 incheas

Peer reviewed data showing rapid retreat in the past ice sheets far faster than today. Much of climate science is thought to be conservative. Meaning some of the numbers above about sea level rise could be much larger if the past comes true today.

20 Times Quicker – Ice Sheets Can Collapse Far Faster Than Previously Thought Possible
Scientists discover that during periods of global warming, ice sheets can retreat at a pace of up to 600 meters per day, which is 20 times quicker than the previous highest recorded rate of retreat.
Their results, reported in the journal Nature, show the former ice sheet underwent pulses of rapid retreat at a speed of 50 to 600 meters per day.
This is much faster than any ice sheet retreat rate that has been observed from satellites or inferred from similar landforms in Antarctica.
“Our research provides a warning from the past about the speeds that ice sheets are physically capable of retreating at,” said Dr. Batchelor. “Our results show that pulses of rapid retreat can be far quicker than anything we’ve seen so far.”
Yes I can believe that ice sheets can melt faster in the past tan they are doing now, but these past melts occurred naturally - not due to human influence. If in hundreds, or thousands of years time our descendants are faced with much higher sea levels then they will have to deal with it. By then the whole situation will be completely different. We might get wiped out by a virus, or reduced to a much smaller population, or we could get mass coronal ejection event, or an asteroid strike etc. In hundreds of years time we will have discovered many new ways to make and store energy and have completely different lives.
ReplyDeleteNote that sea level has been slowly rising for hundreds of years at around 7 or 8 inches per century and so far there has been no change detected at tide gauges around the world (though of course land movements make a big difference).
The link between sea level and humans is strongly correlated. We did it. Before industrialization sea levels were decreasing.

https://www.sciencealert.com/sea-levels-began-accelerating-as-far-back-as-1863-study-finds
For 1,700 years (starting from 0 CE) the current analysis found global sea levels fluctuated between a decline of 0.3 millimeters and an increase of 0.2 mm.
Between 1700 and 1760, right before the Industrial Revolution and the widespread burning of fossil fuels kicked off, sea levels were decreasing by 0.1 millimeters a year.
No serious scientist is claiming that the tiny level of emissions in the 18th and 19th century has had any effect on the temperature of the planet's surface or sea level. But you are right that sea level has fallen at times, though the general direction since the end of the big ice age has been rising. The falls were caused by the little ice ages, which we still don't fully understand the cause of. Even the current level of CO2 is very low. There is no need to panic, which is just as well, because the Chinese, Indians etc. are certainly not about to damage their economies by rushing to net zero. Unilateral cuts by the West will simply allow them to overtake us in a few decades time.

ReplyDeleteThey may beat us to net zero.
