This is money that we could have spent on useful things like education, police, hospitals, sea defences etc.
"Most of that trillion will go on replacing petrol cars with electric ones and gas boilers with electric heat pumps, and on generating, transmitting and distributing the extra electricity needed for these two uses. It also includes a host of other capital projects, including better household insulation. With all that electric demand, we would need extra power stations, extra pylons and upgrades of household electrical circuits. And we would need subsidies for installing the heat pumps and buying electric vehicles."
"There is, of course, one benefit we will supposedly get from this spending: a lower risk of disastrous climate change. So what will climate change cost by 2050? That's a figure known as the 'social cost of carbon' — technically speaking the economic damage done by each additional ton of carbon emissions released into the atmosphere. You almost never hear this discussed any more. Why not? Because all the estimates are embarrassingly small — far smaller than the cost of decarbonising."
We live in the now and yet we can project out into the future. There is a great deal of focus on future cost of climate change. What is clear in all the projections is that the more we pollute GHGs into the atmosphere, the more it will cost the world economy.

Climate change is costing the world $16 million per hour: study
Oct 12, 2023Over the past 20 years, extreme weather events globally, like hurricanes, floods and heat waves, have cost an estimated $2.8 trillion, according to a new study. The study authors estimate the cost of the extreme weather damages from 2000 to 2019 to average around $143 billion, which breaks down to around $16.3 million per hour.

You are assuming that all these extreme weather events could have been avoided if we had not emitted the CO2. That is a claim which has no foundation. If you read the article it says that the small amount of warming by 2050 would actually be beneficial with the extra CO2 increasing plant growth and crop yields.

ReplyDeleteYour focus on AGW is all one sided. THere is science that says certain that has taken place would be impossible in a non warming world.

You have quoted a number of headline statements. but there is no scientific justification for them. The only "methods" that have been used are extremely dubious computer programmes which have been shown to be incapable of replicating real world climate when used retrospectively. The climate system is so complex that present day computer programmes cannot replicate it.
ReplyDeleteThen you haven't done your homework. I have been reading sources on economic damage from AGW for quite awhile. Peer review takes evidence to counter effectively. I hear your opinion.
ReplyDeleteI have done a lot of homework. The fact is that the amount of extreme weather events and their severity has not changed in a measurable way over that past century and so we would not alter that by reducing the amount of CO2 we emit. This whole hugely costly exercise will not change the weather, but it will make us all poorer as there is currently no cheaper reliable alternative to fossil fuels. This may change in the future and then we will transition to that new cheaper improved alternative.
ReplyDeleteBack to weather that would be impossible with global warming. Its one's qualifications to confront the peer reviewed science you disagree with. You are more than welcome to come up with sources that show within peer review scrutiny that todays weather extremes were possible 150 years ago.
ReplyDeleteThere is a field of science called attribution. It is dedicated to parsing out the possibilities of AGW effecting weather. Not everything is extreme in our climate, but the extremes have increased and it is documented in peer review.

The “impossible” events
In some cases, the impacts of climate change are so clear and so overwhelming, scientists conclude extreme weather events would have been all but impossible without global warming. These six events fit the category:
Siberian heat wave, 2020
In 2020, a prolonged, unprecedented heat wave seared one of the coldest places on Earth, triggering widespread wildfires. Temperatures in the small Siberian town of Verkhoyansk hit 104.4 degrees Fahrenheit (38 Celsius), the warmest temperature ever recorded in the Arctic
Pacific Northwest heat wave, 2021
The end of June 2021 was unforgettable for parts of the Pacific Northwest. A historic heat wave killed hundreds, triggered devastating fires and worsened an already unrelenting drought in parts of the region.
Northern Hemisphere drought, 2022
From North America to Europe to China, vast swaths of the Northern Hemisphere experienced extreme drought in the summer of 2022, straining water resources, ruining crops, and priming the landscape for perilous wildfires.
Horn of Africa drought, 2020-2023
A three-year drought in the Horn of Africa, one of the world’s most impoverished regions, has caused crops to wither, water to disappear, and livestock to starve in large parts of Kenya, Somalia and Ethiopia.
Mediterranean heat, 2023
In April, a blistering heat wave with temperatures far more typical of late summer swept Spain, Portugal, Morocco and Algeria, exacerbating a severe drought that had already left crops dry and drained critical water resources.
Extreme heat in South Asia, 2023
Large parts of South Asia faced a brutal heat wave in April. Countries including Vietnam, Myanmar, Laos, India and Bangladesh all saw new all-time temperature records.
