A new paper (Lightfoot, 2020) shows that the claims (a) CO2 and air temperature go up and down together, (b) CO2 and water vapor go up and down together, and (c) warming by water vapor can be added to that of CO2 to give enhanced warming are all not observed to occur in the real world.
In 2020, scientists continued to publish papers affirming global sea levels are today about 2 meters lower than they were a few thousand years ago. During the last interglacial (~116 to 128 thousand years ago), when CO2 peaked at just 280 ppm but surface temperatures were so much warmer that much less water was locked up on land as ice, sea levels were “at least ~7 m to ~9 m above present” and they “could have been as high as 11-13 m above present” at some locations (Muh et al., 2020). ... During the Mid-Holocene sea surface temperatures were also considerably warmer despite CO2 levels only reaching ~265 ppm. Yet at that time sea levels were about 2 or more meters higher than they are today according to an ever-accumulating body of paleo-evidence.
Since 2019, over 40 new studies have been added to the NoTricksZone sea level database:
Meteorologist Anthony Watts: "New data shows the global climate-related death risk has dropped by over 99% since 1920. Despite the near constant caterwauling from climate alarmists that we are in a “climate emergency”, real-world data, release at the end of 2020 shows that climate related deaths are now approaching zero. The data spans 100 years of “global warming” back to 1920 and shows “climate related” deaths now approaching zero. Above is an update of the graph in the 2020 peer-reviewed article by Bjørn Lomborg: Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies."
Bjorn Lomborg reports: “Back in the 1920s, the death count from climate-related disasters was 485,000 on average every year. In the last full decade, 2010-2019, the average was 18,357 dead per year or 96% lower. In the first year of the new decade, 2020, the preliminary number of dead was even lower at 8,086 — 98% lower than the 1920s average.
But because the world’s population also quadrupled at the same time, the climate-related *death risk* has dropped even faster. The death risk is the probability of you dying in any one year. In the 1920s, it was 243 out of a million people that would die from climate-related disasters. In the 2010s, the risk was just 2.5 per million people — a drop of 99%. Now, in 2020, the preliminary number is 1 per million — 99.6% lower.”
"Climate scientists predicted far more global warming than has occurred Since climate scientists’ predictions have proven greatly overstated compared with real-world, measured medium-term warming, the Argonauts decided to find out what climate scientists were getting wrong. In science, any theory – however beautiful or profitable – is false and must be amended or even replaced if real-world data contradict it. The large discrepancy between predicted and real-world warming in recent decades indeed showed there must be something very wrong with the official theory."
Another objection: "Well, we can never know for certain HOW MUCH WORSE it could have been without masks." First, that's not science - that's unfalsifiable nonsense. Maybe consider that the virus is beyond your control.
Since the 1980s, 29% of human CO2 emissions were cancelled out by the CO2-induced greening of the Earth. The post-2000 vegetative greening expansion has been so massive (5.4 million km²) its net areal increase is equivalent to a region the size of the Amazon rainforest.
Boris Johnson, Angela Merkel, Emmanuel Macron, and Narendra Modi will apparently gather in the Netherlands. There, along with Bill Gates, UN head Antonio Guterres, and personnel associated with the European Union, the World Bank, and the International Monetary Fund, they’ll attend a climate summit hosted by the Global Center on Adaptation. ...
We’re told this summit "will launch a comprehensive Adaptation Action Agenda to kick start a transformational decade."
Donna Laframboise: "The chutzpah is astonishing. The global economy is in tatters. Billions face an uncertain future. Health care workers are exhausted. Yet this Clique of Self-Important People™ is full speed ahead, determined to impose its climate vision on the rest of us."
In the last 500 years only some 80 mammals are recorded as having gone extinct. In his book, More From Less, Andrew McAfee, a board member of HumanProgress.org, discusses how relatively rare recorded extinctions are – with some 530 across all species in the last five centuries. More importantly, he notes, the rate of extinction “appear[s] to have slowed down in recent decades; for example, no marine creatures have been recorded as extinct in the last fifty years.”
Matt Ridley, another board member and frequent contributor to this site, argues that despite the human population doubling in the last half-century, “the extinction rate of wild species, especially in the most industrialized countries,” seems to have fallen rather than increased. While absence of evidence isn’t the same as evidence of absence, and there might be millions of unrecorded species in the world’s oceans and tropical forests, the most aggressive claims rest on shaky foundations.
