2024-02-12 07:34:15 +02:00 | ROBERT | No I do not | Other | Climate change is the ubiquitous bogeyman that is the answer for anything that goes wrong at any time. You will never be challenged or rebuked or even corrected. Solar Activity The greatest influence on climate has always been, and will always continue to be, the sun. Sunspots have a significant effect. There are several telescopes atop Mt. Wilson, near Los Angeles, dedicated to the study of sunspots. For overly simplified examples, just notice how much warmer it is during the day than it is at night, and how warmer it is during the summer than it is during the winter. Water Vapor Humidity also has a significant impact on temperature. Water vapor is the predominant greenhouse gas, which absorbs and re-emits energy into the atmosphere. It can have concentration as high as 20,000 parts per million (ppm), which is two percent. During the summers in dry cities, like Los Angeles, temperatures drop significantly at night. In humid cities, like New York, the temperature is often high and uncomfortable all night. Also, cloudy nights are usually warmer than clear nights. Carbon Dioxide Carbon dioxide, on the other hand, is a trace gas. It is currently only about 400 ppm, or 0.04 percent, of the atmospheric mixture. It is not a pollutant. It is produced when animals exhale and by chemical reactions such as combustion of fossil fuels. Green plants use it in photosynthesis to make oxygen for us to breathe. It is essential to all life on Earth. The optimal carbon dioxide level in a commercial greenhouse is 1,100 to 1,500 ppm. There is a strong correlation between the concentration of carbon dioxide in the atmosphere and the degree of forestation, but the correlation between carbon dioxide and temperatures is very weak. If anything, temperatures LEAD carbon dioxide concentrations. There is an equilibrium, known as Henry’s Law, between the carbon dioxide concentration in the atmosphere and the carbon dioxide dissolved in ocean water. Warmer water drives carbon dioxide from the ocean into the atmosphere. Sources of heat are the tremendous number of undersea volcanoes. Historically, the concentration of carbon dioxide has exceeded 1,000 ppm many times. Why weren’t the “tipping points,” that they constantly warn us about triggered? The amount of carbon dioxide produced from human activities is easy to calculate, easy to measure, and therefore easy to tax. There is no peer-reviewed study that proves that carbon dioxide controls climate, or even that Man is the cause. Carbon Dioxide – Oxygen Cycle Sometime in the Precambrian Period (2 billion years ago) plants began to produce oxygen. Soluble iron in seawater reacted with this oxygen to precipitate out, and thus remove, the minerals hematite and magnetite. With these minerals thus deposited, oxygen began to build up in the atmosphere. Lightning strikes, with oxygen present in the atmosphere, result in forest fires. Higher concentrations of oxygen in the atmosphere cause larger and hotter fires. The products of these fires are ash and carbon dioxide. The ash supplies fertilizing nutrients that enable forest regrowth. The carbon dioxide feeds plant growth. The animal kingdom helps the plant kingdom by consuming oxygen and exhaling carbon dioxide. Many plants grow most effectively at carbon dioxide concentrations of 8,000 ppm. Calls to reduce “carbon footprints” are really calls to starve the plant kingdom. Other Greenhouse Gases Methane is even lower in concentration in the atmosphere at about 1.7 ppm. It isn’t even worthy of consideration, and discussions of the digestive characteristics of cows are laughable. Nitrous oxide is lower still at about 314 parts per BILLION. Efforts to curb the use of nitrogen fertilizers are dangerous and can lead to food shortages and mass starvation. Even lower is the concentration of chlorofluorocarbons at about one part per billion, yet we all must buy more expensive and exotic refrigerants each time we recharge our car’s air conditioners. Combustion of Fossil Fuels If burning fossil fuels is the culprit that many say it is, then there would be a commensurate reduction of oxygen, which is necessary for combustion, in the air. That has not happened. Often overlooked is the effect of large volcanic eruptions, which can cause tremendous climate disruptions worldwide. The sulfur dioxide and other aerosols flung into the upper atmosphere cool the planet by blocking out the sun, as evidenced by ice-core samples and tree rings. Historical Trends One thing constant about temperature is that it is never constant. The planet has altered between very cold periods (glacials) and warm periods (interglacials). The glacial-interglacial cycles are controlled by changes in the Earth’s tilt and the shape of its orbit. The earth was warmer in the past. The Vikings, during the Medieval Warm Period, would never have been able to reach North America today with their flimsy wooden boats, as they did a thousand years ago. The Romans, during the Roman Climate Optimum, grew wine grapes in England. Receding glaciers have revealed underlying ancient forests. We are now emerging from the Little Ice Age, which lasted for about five hundred years and only ended in about 1850. Remember that painting of George Washington crossing the Delaware River with chunks of ice floating in the water? That horrifically cold period is known as the Maunder Minimum. Scare Tactics All the climate scaremongering over the past several decades has amounted to nothing more than false predictions. There are no trends showing recent upticks in tropical cyclones, droughts, river floods, or tornadoes. Sea levels have barely risen an inch a decade since 1880. Artic sea ice may be down, but Antarctic ice is up. The polar bear population is up. Energy Policies of the US and Other Nations While the US and the West are proceeding down a path of less energy and more dependence, other nations, like China and India, are building hundreds of coal-fired power plants and embracing energy independence. Warming versus Cooling Let’s not overlook that cold weather causes more deaths than warm weather. Warmer times are better for plants, animals, and people. Warming makes possible an abundance of food and frees the population from its preoccupation with daily survival to do other things, thus leading to cultural development. Bad things happen during cold periods, bringing severe hardship and death. |

2024-02-08 12:07:06 +02:00 | Chantal | No I do not | Other | The entire climate change agenda is a big fat LIE, created purely to control people and usher in the New World Order, which benefits only the "elite". |
2024-02-07 14:17:22 +02:00 | andre | No I do not | Other | Climate change is a hoax. in the 1980 we where told coastlines would be under water..... guess what, no change in the level of the sea in 2024. |
2024-02-07 11:35:18 +02:00 | Pumeza | No I do not | Other | Stop trying to create food shortage |
2024-02-05 15:12:38 +02:00 | Martin | No I do not | Climate change response and finance | Climate Change crisis caused by human activity is pseudo science and not scientifically proven or established. Carbon is not the enemy and in fact earth's important carbon levels to support biological life are at an historical and dangerous low at present and, if anything, we are in need of more carbon, not less to support trees and the natural life support systems. |
