    Who says that article is correct?

    Many comments find is incorrect, I like this one...





    According to the best papers I’ve seen, the emissivity of CO2 is 0.0017. This is the paper by Leckner from the 70’s. That means there’s a shockingly low amount on infrared radiation emitted by the Earth’s surface, that actually is absorbed and re-emitted back to the Earth’s surface. Radiation is also a very weak mode of heat transfer, and the Earth is not a perfect blackbody. By my calculations, roughly 0.00000035×Earth emitted IR radiation, is actually re-emitted back towards the Earth’s surface. I’ve read papers by climate scientists, where they assume CO2 has an emissivity of 1.0. This is pretty intellectually dishonest. I suspect it’s why none of the dire predictions have been even close to correct. For reference, I have a master’s in ME from Stanford, and worked most of my career as a spacecraft thermal design engineer for the US Naval Research Laboratory. I did radiation heat transfer calculations almost daily for over a decade. If my models weren’t correct, and properly correlated to testing, spacecrafts would fail to work, and I’d likely have been fired. Climate scientists never get fired, despite their predictions being wrong 100% of the time.

      1. Instrumental Surface Temperatures
      • Global Temperature Rise: The Earth's average surface temperature has increased by about 1.1–1.5°C (2–2.5°F) since the late 19th century.
      • Record-Breaking Years: The last decade (2015–2024) was the warmest on record. 2024 currently holds the record as the hottest year, while preliminary data for 2025 indicates it is on track to be the second- or third-warmest.
      • Rapid Rate: Warming is occurring approximately 10 times faster than the average rate of ice-age-recovery warming.

        Do scientists agree on climate change?

        Earth-orbiting satellites and new technologies have helped scientists see the big picture, collecting many different types of information about our planet and its climate all over the world. These data, collected over many years, reveal the signs and patterns of a changing climate.

        Scientists demonstrated the heat-trapping nature of carbon dioxide and other gases in the mid-19th century.2 ([url]https://science.nasa.gov/climate-change/evidence/#footnote_2[/url]) Many of the science instruments NASA uses to study our climate focus on how these gases affect the movement of infrared radiation through the atmosphere. From the measured impacts of increases in these gases, there is no question that increased greenhouse gas levels warm Earth in response.

        Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly 10 times faster than the average rate of warming after an ice age. Carbon dioxide from human activities is increasing about 250 times faster than it did from natural sources after the last Ice Age.3 ([url]https://science.nasa.gov/climate-change/evidence/#footnote_3[/url])

              Obviously not flat earthers and climate change deniers! LOL

              First you say the science is all wrong. But when I challenge that bold faced lie, you switch to nobody cares?

              Our economy has been doing better than expected since Trump tariffs.

              The US has a similar affordability problem and he has made it worse with tariffs.

                Arguing the science would fit Mallee's WOMBAT description.
                Don't see much of that since people have dropped climate change from their list of important issues.
                Your part of the 17% who are zealots.
                A small minority.
