A study by environmentalist Bjorn Lomborg shows that the crazed, spittle-specked proclamations that climate change will destroy the world and kill everyone are unfounded in the facts.
The study, entitled, “Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies,” says that the facts seem to show that human welfare has steadily increased as humanity increases scientific and technological capabilities and climate change won’t put much of a dampener on that rate of improvement.
“Climate change is real and its impacts are mostly negative, but common portrayals of devastation are unfounded. Scenarios set out under the UN Climate Panel (IPCC) show human welfare will likely increase to 450% of today’s welfare over the 21st century. Climate damages will reduce this welfare increase to 434%.” Lomborg says at the start of his abstract for the 2020 study.
Lomborg added that widespread proclamations about disaster are filled with false conclusions.
Arguments for devastation typically claim that extreme weather (like droughts, floods, wildfires, and hurricanes) is already worsening because of climate change. This is mostly misleading and inconsistent with the IPCC literature. For instance, the IPCC finds no trend for global hurricane frequency and has low confidence in attribution of changes to human activity, while the US has not seen an increase in landfalling hurricanes since 1900. Global death risk from extreme weather has declined 99% over 100 years and global costs have declined 26% over the last 28 years.
Arguments for devastation typically ignore adaptation, which will reduce vulnerability dramatically. While climate research suggests that fewer but stronger future hurricanes will increase damages, this effect will be countered by richer and more resilient societies. Global cost of hurricanes will likely decline from 0.04% of GDP today to 0.02% in 2100.
Climate-economic research shows that the total cost from untreated climate change is negative but moderate, likely equivalent to a 3.6% reduction in total GDP.
He added that the costs in dollars to economies from climate policies far out weigh their benefits (and that 3.6% reduction in total GDP).
The fact is, everything the climate alarmists tell you is false.
