Deserts are very hot, but the air in them is very dry. If the theory of water vapour feedback which you describe were true then the greatest amount of global warming should be found in the troposphere above the tropics. This tropical "hot spot" has never been found in practice, hence this theory is wrong. This is why all the computer climate models, which are programmed with this "positive feedback" give predictions which are too hot.Derek Tipphttps://www.blogger.com/profile/07893712146272196994noreply@blogger.comtag:blogger.com,1999:blog-1881436054697063063.post-73856283655484705962024-03-18T04:38:59.008+00:002024-03-18T04:38:59.008+00:00[[[[[[[[[“Ninety-five percent of the greenhouse ef...[[[[[[[[[“Ninety-five percent of the greenhouse effect is caused by water vapor, and the man-made CO2 input is insignificant. Climate is governed by solar activity, ocean currents, the thermoregulatory function of clouds: anthropogenic CO2 is background noise. The increase in CO2 is a consequence of humanity’s increased prosperity from the use of fossil fuels. In addition, due to increased CO2, the Earth is greener and food production is increasing. CO2 cannot impact Earth’s climate and has beneficial effects on Earth’s biomass. The use of fossil fuels, the growth of human population and the increase of CO2 are divine blessings. I have lived all my life as a scientist, and scientists speak on the basis of established theories and reproducible empirical evidence to support their claims: everything I have said is backed up by solid empirical evidence.”]]]]]]]]<br /><br />My guess is Dr. Park actually knows the true science of water vapor and co2. Water vapor is a pos. feedback to co2. The more co2, the more temperture increases, the more water vapor increases. Since water vapor is also a GHG, the temperature increases even more.<br /><br />Also water vapor WV has a very short atmospheric lifetime. From other sources WV only has about a day residency in the atmosphere. While co2 last for centuries in the atmosphere. WV is a significant contribution to global warming. This is the area of climate sensitivity. The agreed on climate sensitivity, for every degree that co2 increases temperature, we are actually getting 3*C. Positive feedback is what drives the dangerous change in our atmosphere for increasing temperatures.<br /><br />https://skepticalscience.com/news.php?p=2&n=345<br /><br />How does this work? The amount of water vapor in the atmosphere exists in direct relation to the temperature. If you increase the temperature, more water evaporates and becomes vapor, and vice versa. So when something else causes a temperature increase (such as extra CO2 from fossil fuels), more water evaporates. Then, since water vapor is a greenhouse gas, this additional water vapor causes the temperature to go up even further—a positive feedback.renewableguyhttps://www.blogger.com/profile/00155425043292767903noreply@blogger.comtag:blogger.com,1999:blog-1881436054697063063.post-25486715412588695202024-03-16T18:04:49.446+00:002024-03-16T18:04:49.446+00:00That's interesting.

Projected out from 2025 to 2030 a CAGR of 2% per year decreases. Its actually a lower growth rate compared to the past. Decreasing use of FFs has a savings in heat pumps that will be passed onto the owners of the buildings. This is not discussed in your blog on here. LOwering the cost of living has to be taken into account with this investement.<br /><br />The same goes for the world wide investment in clean energy and more efficient appliances. Clean energy benefits come with lower costs of energy, better health, lower costs of health. <br /><br />Going back to the great stink of the 1850s when GB decided to get sewer systems. The cost was quite high, but there were also greater benefits to the society for a much better way to handle human sewage. This the standard now all over the world.<br /><br />Same goes for FF burning. The benefits are far greater than the costs it takes to get there.renewableguyhttps://www.blogger.com/profile/00155425043292767903noreply@blogger.comtag:blogger.com,1999:blog-1881436054697063063.post-9096628027817126172024-03-15T14:41:55.337+00:002024-03-15T14:41:55.337+00:00Net Zero goals have extended but not dropped.

In order for this to be undersea volcanoes, one would have to show that volcanoes are increasing in the ocean. And with cooling one would have to show decreasing volcano activity. What really correlates and has the mechanism is GHGs. The 800,000 years of temperature vs GHGs in the atmosphere is lock step together.<br /><br /><br />https://skepticalscience.com/How-Increasing-Carbon-Dioxide-Heats-The-Ocean.html<br /><br /><br />Ocean warming not just skin deep <br />Because of their effect on lowering the temperature gradient of the cool skin layer, increased levels of greenhouse gases lead to more heat being stored in the oceans over the long-term. This ocean warming mechanism has been observed experimentally, and is also supported by numerical modeling. <br /><br />So although greenhouse gases, such as carbon dioxide, don't directly warm the oceans by channeling heat down into the oceans, they still do indeed heat the oceans, and are likely to do so for a very long time. <br /><br /><br />https://www.ncei.noaa.gov/access/global-ocean-heat-content/renewableguyhttps://www.blogger.com/profile/00155425043292767903noreply@blogger.com
