Runaway Global Warming: How Dinosaurs Survived07-12-2025 02:12
Im a BM ★★★★★ (2830)	During the more than one hundred million year reign of the dinosaurs, atmospheric concentrations of CO2 were MUCH higher than they are today. How did the dinosaurs survive despite the "runaway global warming" that they say would occur if such high levels of CO2 happened today? For more than a hundred million years, sea water flowed freely between the two great continents of the western hemisphere. A unified global current carried warm tropical water toward the poles for cooling. This melted any sea ice, and there were no glaciers except at very high elevation. Temperate forests all around the Arctic and Antarctic. After getting its polar refrigeration, the global current headed back toward the tropics to keep the corals cool. The conditions of ocean circulation were so different then, runaway global warming wasn't going to happen, even with CO2 an order of magnitude higher than it is today. Conditions changed since then. A LOT. By three million years ago, the closure was complete and Panama sealed off what was left of the gap through which the global current flowed. The squeezing had been going on for a few million years already, reducing the flow to a trickle. And then that was the end of the unified global current. That changed EVERYTHING. CO2 concentrations plummeted, and glaciers began to grow. It was the beginning of a whole new climate regime with a highly sensitive thermostat. No more polar refrigeration of tropical water by a unified global current. There is now the distinct potential for "runaway global warming" to occur if CO2 gets jacked up to anything close to what the dinosaurs lived with.

It is much windier now IMO. https://uccastandoff12424.blogspot.com/2024/01/this-blog-post-is-about-relationship.html

Did you ever explain why any rational adult should believe something as absurd as your ability to travel time to verify atmospheric CO2? ... or that you are somehow omniscient? Im a BM wrote:How did the dinosaurs survive despite the "runaway global warming" that they say would occur if such high levels of CO2 happened today? They falsified the insane notion that there could ever be any increase in temperature from simply adding CO2. Do you have any idea why mindless warmizombies are never known for their intelligence? Im a BM wrote: For more than a hundred million years, sea water flowed freely between the two great continents of the western hemisphere. A unified global current carried warm tropical water toward the poles for cooling. This is more of your omnisicence fallacy, yes? Im a BM wrote:By three million years ago, the closure was complete and Panama sealed off what was left of the gap through which the global current flowed. The squeezing had been going on for a few million years already, reducing the flow to a trickle. And then that was the end of the unified global current. That changed EVERYTHING. All it did was cause the lobsters living on either side of Panamá to evolve differently. No rational adult has any reason to believe that Panama's climate was any different from the way it is today. Im a BM wrote: CO2 concentrations plummeted, and glaciers began to grow. You've got to be kidding me. Did you say that you claim to be a scientist or a science-fictionist? . I don't think i can [define it]. I just kind of get a feel for the phrase. - keepit A Spaghetti strainer with the faucet running, retains water- tmiddles Clouds don't trap heat.

Just more hand waving that it applies to everything and more asserting that the greenhouse effect 'violates' it.- Ceist

Into the Night★★★★★ (23472)	And now for some more made up 'history'. Another example of declaring events that were NEVER OBSERVED and yet taken as ABSOLUTE GOSPEL. Im a BM wrote: During the more than one hundred million year reign of the dinosaurs, atmospheric concentrations of CO2 were MUCH higher than they are today. What 'hundred million year reign of the dinosaurs? Did they have a golden crown? What type of government did they create? It is not possible to measure the CO2 of the Earth. Im a BM wrote: How did the dinosaurs survive despite the "runaway global warming" that they say would occur if such high levels of CO2 happened today? Whataboutism. Pointless question. It is not possible to measure the temperature of the Earth. No gas or vapor has the capability to warm the Earth. You are AGAIN ignoring the 1st law of thermodynamics. Im a BM wrote: For more than a hundred million years, sea water flowed freely between the two great continents of the western hemisphere. It still does, Robert. Im a BM wrote: A unified global current carried warm tropical water toward the poles for cooling. So I guess you have no concept of ocean currents either, or how they form, or where they are. Stuff mariners have used for as long as there have been oceangoing ships. Im a BM wrote: This melted any sea ice, and there were no glaciers except at very high elevation. Current is not ice. The ocean is not on top of mountains. Im a BM wrote: Temperate forests all around the Arctic and Antarctic. What 'temperate forests'??? Trees can't grow in ocean water! What is 'temperate' about any Arctic region?? Im a BM wrote: After getting its polar refrigeration, the global current headed back toward the tropics to keep the corals cool. Poles aren't a refrigerator, Robert. You are again ignoring ocean currents, what creates them, and where they are. Im a BM wrote: The conditions of ocean circulation were so different then, runaway global warming wasn't going to happen, even with CO2 an order of magnitude higher than it is today. Conditions changed since then. A LOT. No gas or vapor has the capability to warm the Earth, Robert. You are AGAIN ignoring the 1st law of thermodynamics. You cannot create energy out of nothing. Im a BM wrote: By three million years ago, the closure was complete and Panama sealed off what was left of the gap through which the global current flowed. The squeezing had been going on for a few million years already, reducing the flow to a trickle. And then that was the end of the unified global current. What 'squeezing'?? What was 'squeezed'?? What 'closure'?? What 'unified global current'?? You are ignoring Europe, Asia, Africa, and north and south America. You also have NO concept of how currents form or where they are. Im a BM wrote: That changed EVERYTHING. CO2 concentrations plummeted, and glaciers began to grow. Still making shit up. Argument from randU fallacies. It is not possible to measure the global content of CO2. It is not possible to measure the global ice content. Im a BM wrote: It was the beginning of a whole new climate regime with a highly sensitive thermostat. There is thermostat, Robert. Climate is not a form of government. Im a BM wrote: No more polar refrigeration of tropical water by a unified global current. The Polar Refrigeration Company is located in Vancouver, WA. They are not located in the water and do not build systems to refrigerate tropical water. Im a BM wrote: There is now the distinct potential for "runaway global warming" to occur if CO2 gets jacked up to anything close to what the dinosaurs lived with. What 'runaway global warming'??? It is not possible to measure the temperature of the Earth. It is not possible to measure the global CO2 content. No gas or vapor has the capability to warm the Earth. You cannot create energy out of nothing. The Parrot Killer Debunked in my sig. - tmiddles Google keeps track of paranoid talk and i'm not on their list.
