Not available in my region due to rights restrictions. Global sea level rise is a good example for why adaptation should be a priority. First, we must learn that coastlines are not static, not just on geological timescales, but also on human timescales. There are local variations of sea level relative to land, there is erosion, and sediments change. On top of that there are global changes due to changes in climate. Even if were able to control climate to keep the sea level steady globally, we would still have to adapt. And according to the IPCC reports, our action against global warming does not make much of a difference, a 30 cm (best estimate) difference by 2100 between the least action and most action scenarios, if I recall correctly. This means that diverting money from adaption to fairly futile attempts to control climate is not a good idea.

Yes, I posted many links. I'm on several climate/weather forums where real climatologists talk about this alll the time.
I was more looking for relatively undisputed reviewed literature. In particular, that climate change effects can include things like "air quality is much more poor with higher rates of asthma" is pretty surprising considering how bad things were before proper regulations (for emissions not related to CO2) were in place. Whilst you can surely find expanding cities in developing nations with poorer air quality, if global climate change is to blame, you should see a drop in air quality everywhere. I'm also curious how a different climate influences air quality in the first place.
Even though climate change introduces some challenges, the world even during my lifetime (46 years) has become a much, much better place to live. People are healthier, life expectancy has gone up quite a bit, extreme poverty has dropped by much, far fewer die from wars and conflicts. To paint a picture of an increasingly suffering humankind, not in some hypothetical future, but right now, is simply very incorrect.
It depends on where you live. In the United States we have been coddling to the fossil fuel and chemical industries, which is why things here are worse (and that includes income disparity.) The regulations you speak of- they are simply not followed here, or are being rolled back, at the behest of those industries (thanks to dark money.) There are over two thousand toxic waste dumps and superfund sites within about 200 miles of my house where corporations have been dumping toxic chemicals which seep into the water supply- not to mention the plastics being dumped into the ocean. We've banned the use of plastic here, but that doesn't mean others have. You should look into the extended drought in Central America, where people are mass migrating to the US southern border because of it. The Trump administration is treating them like prisoners of war, but there is mass starvation going on down there and that's why they are coming here. That's undisputed. So is the mass migration of people from islands that are going to be completely underwater or are getting there now (like the islands off the Louisiana coast.)
I didn't mention this in the last post but I should have- the big dead pool of water in the Gulf of Mexico is due to run off of pesticides and fertilizer coming down the Mississippi- those chemicals have created excessive blue green algae (a type of bacteria), we're seeing the same blooms here in the NE and people are being warned to avoid those lakes because they cause skin burns and the chemicals seep in through the skin and cause stomach problems. Runoff has caused those chemicals to appear in our water supply during the warm months and we dont drink tap water because of it- I figured that out a few years ago when I began having stomach problems every warm season after drinking tap water. I spoke with an expert in the field, Dr. Tracy Fanara, who works with the MOTE research lab down in Florida and she explained how bad the blooms have gotten in recent years, and we've started to recommend that people stop using excessive pesticides and fertilizer in their crops as the spring floods have gotten much worse and there's been more run off of these dangerous chemicals not just into the sea and gulf, but also into lakes and streams and rivers.
The idea of achieving net carbon zero by 2050 is a mainstream scientific and industrial position.
Also, being in the middle of an mass extinction- I wouldn't call those times "great."
As far as the higher smog is concerned, yes times are better than they were in the 70s- but things are getting worse now for different reasons than they were bad in the past. The higher amount of forest fires the West is having now are causing huge problems as noted below:https://grist.org/article/california-smog-is-getting-worse-again-but-because-of-climate-change-not-cars/
Hospitals have been reporting increased visits from patients seeking treatment for respiratory ailments this summer in Southern California. The culprit? Smog.
Southern California has experienced its worst smog in seven years. Ozone levels have exceeded federal standards on 91 days in 2016, nearly 30 percent more than this time last year, according to the Los Angeles Times. Every day of August has exceeded the federal standard of 70 parts per billion.
Cities like Los Angeles have never been known for making it easier to breathe. Yet as bad as the air currently is, it’s still far better than than it was in the ’70s and ’80s, when LA had 200 smog-filled days a year.
While emissions from vehicles are usually the culprit behind smog, the reason for this season’s poor air quality has more to do with the particularly hot and dry weather, and an influx in wildfire activity. Ozone regulations and federal fuel efficiency standards for trucks and cars, meanwhile, have helped cities cut pollution.
But in the future, as climate change increases both wildfires and temperatures in the region, it’ll take even greater effort to make Southern California’s air clean again.https://www.latimes.com/local/lanow/la-me-coachella-smog-climate-change-20190412-story.html
Air quality officials will miss a 2019 federal deadline to clean smog in the Coachella Valley, saying the challenges of “hotter summer weather and the threat of climate change” are hampering efforts to slash health-damaging ozone.
The South Coast Air Quality Management District said Friday that because of an increase in smog over the last two years it would seek to downgrade the area’s ozone pollution rating from “severe” to “extreme” — the worst federal classification. The change, if approved by the U.S. Environmental Protection Agency, would give the agency five more years to cut Coachella Valley ozone levels below 80 parts per billion.
Though it’s hardly the first pollution-reduction deadline Southern California has busted, the request is notable in highlighting how climate change might be a new front in the war against smog.
Ozone, the lung-searing gas in smog that triggers asthma and other respiratory illnesses, has surged in Southern California in recent years, bucking a decades-long trend of improvement. Air quality officials blame persistent, record-breaking heat and stagnant weather — rather than an increase in emissions — for boosting levels across California and other Western states.
Regulators and scientists say global warming will make smog harder to control because higher temperatures speed up the photochemical process by which pollution from factories, power plants, vehicles and other sources form ozone.
“We do know that the changing climate plays a role in air quality,” South Coast air district spokeswoman Nahal Mogharabi said in an email. “Hotter temperatures and stagnant weather experienced throughout California have directly led to increases in high levels of ozone and fine particulate matter during certain parts of the year.”
Capitalism and the industrial revolution have caused most of these problems and the reason why the fossil fuel industry is being sued, along with the pharmaceutical industry and the chemical industries, is because they covered up research in their greed for profit. We've banned fracking here because we saw a big rise in earthquakes in places like Oklahoma where it's occurring, as well as banned further pipelines and new gas and oil heating being utilized in new constructions because of the risks associated with them (fires, explosions, etc.) That's why we're seeing a wave of environmentalism now, to fix the problems caused by the previous generation, thats created a new generation of people who are more obese and unhealthy than they were before, as well as children living near farming communities who are showing up with a higher rate of brain injuries from exposure to chemicals by companies that find their way around regulations through their connections with local politicians and regulatory agencies, who are also being sued. Our life expectancy has also gone down for the first time in many generations.https://www.latimes.com/local/lanow/la- ... story.htmlhttps://www.latimes.com/politics/story/ ... -chemicalshttps://grist.org/article/elizabeth-war ... that-mean/
and this from the climate and weather forum
The low sea ice and resulting Arctic amplification is a big reason why Utqiakvik (Barrow) had its latest first freeze on record (9/19 vs. the old record of 9/7) and has a chance of registering its first September with a mean temperature of 40° or above. The current monthly record is 37.7°.
That’s a remarkable stat. Just saw it posted on twitter. Record warmth and high pressure over the Arctic since May.https://mobile.twitter.com/AlaskaWx/sta ... 4578295808https://mobile.twitter.com/ZLabe/status ... 2216029185
One other statistic: Utqiagvik had 55 days with low temperatures of 40 or higher. The old record was 32.
And a frost free period of 85 days. Remarkable. One wonders what that's doing to the permafrost this year. Last few years the situation further south (near Fairbanks) has been bad enough that the active layer isn't completely refreezing during the winter, creating a layer of permanent thaw sandwiched in between. A situation which wasn't expected until quite a bit later in the century.https://www.americanwx.com/bb/topic/486 ... nt-5321035https://www.americanwx.com/bb/topic/486 ... e/page/56/
Utqiagvik (formerly Barrow) remains on course for a record warm September. It is also increasingly likely to see its first September with a mean temperature of 40.0° or above. Overall, largely on account of low summer sea ice, resulting in Arctic amplification, the area has been warming very rapidly.
Notice the much greater amplitude of the Arctic pressure pattern swings since 1990. This would seem to match the 2009 corals study.The record summer Arctic dipole pattern from 2007 to 2012 and new lowest extent. Rapid reversal in 2013 and 2014. Then stronger dipole anomalies in 2016 and 2019. Continuation of the long term Arctic sea ice decline with very choppy volatility from year to year.https://www.sciencedaily.com/releases/2 ... 101200.htm
Swings In North Atlantic Oscillation Variability Linked To Climate Warming
Anthropogenic (human-related) warming does not appear to be altering whether the NAO is in a positive or negative phase at multi-decadal time scales,” said WHOI paleoclimatologist Konrad Hughen. “It does seem to be increasing variability. Clearly, this has implications for the future.”
“As temperatures get warmer, there’s potential for more violent swings of the NAO — the phases becoming even more positive and even more negative,” Hughen added. “If the NAO locks more into these patterns, intense storms will become more intense and droughts will become more severe.”
At least some research shows that at least parts of the Arctic today are the warmest in at least the last 44,000 years.https://agupubs.onlinelibrary.wiley.com ... 13GL057188
Also, as for what's causing the really bad air quality here in NYC and LI, I can point to the steep increase in dew points, we broke the record by more than double, with 42 days with a dew point higher than 75 at JFK, and the higher humidity levels have been trapping car pollutants and we've had numerous ozone alerts, much moreso than normal. Allergy seasons have also been extending much farther the last few years and breathing problems are now very common here in the warm season. We've also seen a steep rise in tropical infections like EEE and West Nile passed by mosquitoes. A dozen deaths from EEE alone and numerous warnings to not go outside around dusk here.
