Why global warming is good for us

It doesn't seem to bother all the leftist politicians buying ocean front property.

After the last 27 years, I have not seen any change in the shoreline where I live.
We have not had a major hurricane since 1989 and no change in frequency.

The Allegedly Wise Close Eyes to Facts About Global Warming

On March 2, the Wall Street Journal published an article by Princeton economist and former Vice Chairman of the Federal Reserve Board Alan Blinder that includes this: “Climate change is the existential issue of our time. Nothing else poses a comparable threat to the continuation of human life on the planet.”

Putting aside Russia’s accelerating slaughter of Ukrainian civilians when

Blinder’s article was published, his statement ignores facts that show that the benefits of global warming more than offset any harms that it may cause.


As environmental statistician Bjørn Lomborg reported on September 16, 2021, “Global warming now prevents more than 166,000 temperature-related fatalities annually.” His statement is supported by three studies that analyzed millions of deaths in numerous countries over recent decades and found that cooler temperatures kill several times more people than warmer temperatures.
Global warming, Matt Ridley has recently explained, also improves forest, grassland, and tree leaf growth and raises agricultural yields.


The facts regarding natural disasters also are positive

Higher Carbon Dioxide Levels Prompt More Plant Growth, But Fewer Nutrients | CFAES (osu.edu)

It might seem there’s an upside to the rising levels of carbon dioxide in the atmosphere. Plants are growing faster.
However, in many species of plants, quantity is not quality. Most plants are growing faster, but they have on average more starch, less protein and fewer key vitamins in them, said James Metzger, a professor and chair of the Department of Horticulture and Crop Science in The Ohio State University’s College of Food, Agricultural, and Environmental Sciences (CFAES).


New IPCC report highlights urgency of climate change impacts (skepticalscience.com)

The new IPCC Working Group II report paints an alarming picture of rapidly growing risks currently being felt around the world, including widespread damages to human and ecological health. It finds nearly half the world population living “in contexts that are highly vulnerable to climate change.”For example, the IPCC says in its report that climate change has exacerbated food and water insecurity, extreme weather disasters, declines in people’s physical and mental health, premature deaths, species loss and extinctions, and vector-borne diseases in regions around the world.
Extreme weather causing food and water insecurity

The new report echoes the IPCC Working Group I report from August 2021 in finding that climate change is worsening extreme weather events like heat waves, droughts, wildfires, floods, and hurricanes. “Increasing weather and climate extreme events have exposed millions of people to acute food insecurity and reduced water security,” the report finds.Those concerns are reported as especially problematic in sub-Saharan Africa and Central and South America, which along with portions of Asia are the most vulnerable regions to climate change impacts. These equatorial countries also lack the resources to deploy climate adaptation measures. Climate-worsened droughts and floods in recent years have increased acute food insecurity and malnutrition in these regions.Over the past 50 years, technological advances have increased global food productivity, but climate change has slowed that growth. The IPCC projects that rising temperatures will decrease agricultural productivity in many regions, including much of North America. As IPCC report coordinating lead author Rachel Bezner Kerr said in a press briefing, “Climate change is projected to reduce overall yields of important North American crops such as wheat, maize, and soybeans” and also have adverse impacts on livestock and fisheries. “The picture is stark for food systems,” she added. “No one is left unaffected by climate change.”Worsening droughts and shrinking glaciers and snowpacks have also contributed to water insecurity in many regions. The IPCC concludes that roughly half of the world’s population currently experiences severe water scarcity for at least some part of the year.

But it is funny to hear them while thinking to yourself- "these guys understand politicians are just pandering to them, right? No nation is going to spend the money that would be needed to implement their schemes. Especially with only computer models."

I think you are confusing climate models with carbon emission scenarios. I have never thought that the "business as usual" carbon emissions scenario was something that was very likely. I believe that
a moderate or slightly lower than moderate emissions scenario is most likely. Either a moderate or slightly less than moderate emissions scenario will result in dangerous climate change by the year
2100 and beyond. There are many different climate models and some of them are not reliable for projecting the climate. Climate scientists are aware of this. There are others that seem to be quite
accurate.

Yet you do believe future scenarios based on climate models. RCP8.5 is the least likely scenario yet that is what is used as business as usual for the alarmism.

And as such, politicians will pay lip service and do less than were the alarmist be less alarmist.

The lies gets dumber and dumber, the increased efficiency of CO2 plant intake as it increases in the air means better plant growth and survival against drought and expand its habitat area.

The Carbon Brief has a lengthy article the summarizes the main conclusions of the IPCC's AR6 report.

In-depth Q&A: The IPCC’s sixth assessment report on climate science - Carbon Brief

How are weather extremes changing and what role does climate change play?

On heavy rainfall events, the report concludes that their frequency and intensity “have likely increased at the global scale over a majority of land regions with good observational coverage”. Human influence is likely the main driver, it says.
The report suggests that observed changes in flooding and drought are less clear-cut, not least because there is more than one way to define these events and they both involve “a complex interplay of hydrology, climate and human management”.
Nonetheless, the authors conclude with medium confidence that climate change has “contributed to decreases in water availability during the dry season over a predominant fraction of the land area due to evapotranspiration increases”.
For flooding, the report says “confidence about peak flow trends over past decades on the global scale is low”, but it notes that “there are regions experiencing increases, including parts of Asia, southern South America, the north-east US, north-western Europe and the Amazon, and regions experiencing decreases, including parts of the Mediterranean, Australia, Africa and the south-western US”.
On tropical cyclones (TC) – powerful storms that develop in the warm ocean waters of the tropics – the report says “it is likely that the proportion of major TC intensities and the frequency of rapid intensification events have both increased globally over the past 40 years”.
This compares to AR5, which concluded (pdf) that “confidence remains low for long-term (centennial) changes in tropical cyclone activity, after accounting for past changes in observing capabilities”


Projections

Looking ahead, the AR6 report finds that “regional changes in the intensity and frequency of climate extremes generally scale with global warming”. It adds:

“New evidence strengthens the conclusion from [the IPCC’s special report on 1.5C of warming] that even relatively small incremental increases in global warming (+0.5C) cause statistically significant changes in extremes on the global scale and for large regions (high confidence).”

This is particularly the case for “temperature extremes (very likely), the intensification of heavy precipitation (high confidence) including that associated with tropical cyclones (medium confidence), and the worsening of droughts in some regions (high confidence)”, the authors note.

On tropical cyclones, the report concludes – with high confidence – that “the proportion of intense TCs, average peak TC wind speeds, and peak wind speeds of the most intense TCs will increase on the global scale with increasing global warming”.
It adds, with medium confidence, that “the total global frequency of TC formation will decrease or remain unchanged with increasing global warming”.

Your overreliance on the IPPC is bad as it is making you miss a lot of real world and science that shows a very different picture.

CO2 warm forcing at the 430 ppm level is a pittance in the heat budget and the postulated DOUBLING isn't a concern either as it is still a pittance in the heat budget.

Where is the Climate Emergency?

Next, here is the radical change in downwelling radiation at the surface from the increase in CO2 that is supposed to be driving the “CLIMATE EMERGENCY!!!” What I’ve shown is the change that in theory would have occurred from the changes in CO2 from 1750 to the present, and the change that in theory will occur in the future when CO2 increases from its present value to twice the 1750 value. This is using the generally accepted (although not rigorously derived) claim that the downwelling radiation change from a doubling of CO2 is 3.7 watts per square metre (W/m2). The purpose is to show how small these CO2-caused changes are compared to total downwelling radiation.




The changes in downwelling radiation from the increase in CO2 are trivially small, lost in the noise …

There are some benefits to a small amount of global warming as pointed out by Matt Ridley. He fails to discuss the costs of a larger amount of warming, such as a greater than
2 degree C. increase in the GMT relative to the 1850 - 1900 period. Most or all of the coral reefs would be wiped out with a 2 degree C. temperature increase in the GMT.
I don't think that Matt Ridley consulted the latest IPCC AR6 report - the IPCC has greater confidence that human activities are causing the strongest (mainly category 4 and 5 tropical cyclones)
to get stronger.

Sea levels along the U.S. coast are projected to rise between 10 - 12 inches by the year 2050 and 2 feet of sea level rise is projected by the year 2100. A 2 degree increase
in the GMT might be enough to destabilize West Antarctica and cause 6 feet of global average sea level rise over a period of around 1000 years from West Antarctica alone.
Greenland could also be destabilized and most of the late summer Arctic sea ice would disappear. The Atlantic Meridional Overturning Circulation would be weakened.
Ocean oxygen levels would decrease.

Reducing carbon emissions will limit sea level rise -- ScienceDaily

Even under the most optimistic scenarios outlined in the Paris Agreement -- keeping the overall warming of Earth to 1.5 degrees (Celsius) -- sea levels will continue to rise by several meters over the next few thousand years. If humans continue to burn fossil fuels so that temperatures meet the 2-degree (Celsius) threshold outlined in the Paris Agreement, global mean sea level rise may exceed nine meters, or nearly 30 feet.



AR6 WGI Summary for Policymakers Headline Satements (ipcc.ch)
A. The Current State of the Climate

A.3 Human-induced climate change is already affecting many weather and climate extremes in every region across the globe. Evidence of observed changes in extremes such as heatwaves, heavy precipitation, droughts, and tropical cyclones, and, in particular, their attribution to human influence, has strengthened since the Fifth Assessment Report (AR5).

B. Possible Climate Future

B.1 Global surface temperature will continue to increase until at least the mid-century under all emissions scenarios considered. Global warming of 1.5°C and 2°C will be exceeded during the 21st century unless deep reductions in carbon dioxide (CO2) and other greenhouse gas emissions occur in the coming decades.
B.2 Many changes in the climate system become larger in direct relation to increasing global warming. They include increases in the frequency and intensity of hot extremes, marine heatwaves, and heavy precipitation, agricultural and ecological droughts in some regions, and proportion of intense tropical cyclones, as well as reductions in Arctic sea ice, snow cover and permafrost.
B.3 Continued global warming is projected to further intensify the global water cycle, including its variability, global monsoon precipitation and the severity of wet and dry events.
B.4 Under scenarios with increasing CO2 emissions, the ocean and land carbon sinks are projected to be less effective at slowing the accumulation of CO2 in the atmosphere.
B.5 Many changes due to past and future greenhouse gas emissions are irreversible for centuries to millennia, especially changes in the ocean, ice sheets and global sea level
