Phd thesis on global warming

The models get core assumptions wrong — the hot spot is missing 22 — 26, 28 — 31 Clouds cool the planet as it warms 38 — 56 The models are wrong on a local, regional, or continental scale. Figure 1 Climate Sensitivity Comparison empirical methods versus models, for a doubling of the CO2 level.

The direct effect of CO2 is only 1. Models amplify that warming with assumptions about positive feedback see the blue region of model estimates in the graph below. But observations show that net feedback is probably negative, which would instead reduce the direct effect of the extra carbon dioxide.

While independent scientists point to the empirical evidence, government funded scientists argue that a majority of scientists, a consensus, support the theory that a man-made catastrophe is coming. The test of scientific knowledge is through experiment and observation.

The only evidence the government scientists provide on the key points of attribution the cause of the warming come from simulations of the climate done with computers. A multitude of observations are in rough agreement that any increase in global average temperature caused by a doubling of CO2 is more likely to be about half a degree than the 3.

The major problem for models: Feedbacks Our climate changes because of outside effects, called forcings: The Earth is a ball of magma, is a 12, km thick, with a thin crust about 12 km of rock on top, who knows what effects come from within? The IPCC recognizes only two types of forcings: Forcings are difficult to unravel.

Harder still are feedbacks, as systems all over the planet simultaneously adjust to changing conditions. In a warmer world, for instance, less ice and more plant-life means less sunlight is reflected to space, which creates more warming. The oceans release carbon dioxide, more water evaporates, humidity changes, sea-levels rise, and all of those consequent changes further affect temperatures.

Indeed while CO2 may cause one degree of warming, the feedbacks amplify this — theoretically anyway — by up to three degrees. The major agent of feedback, according to the IPCC, is water vapor ie.

Some details matter more than others. Models assume that relative humidity will stay the same over the tropics as the world warms, that clouds are a positive feedback and not a negative one, and that cloud changes are a feedback and not a forcing in their own right.

These are three critical and demonstrable errors.

In addition, if Miscolscki is right, and an increase in carbon dioxide leads to a decrease in water vapor, then the sensitivity due to CO2 could be close to zero. The global warming predictions are contradicted by the data.

The exception proves that the rule is wrong.

That is the principle of science. If there is an exception to any rule, and if it can be proved by observation, that rule is wrong. Lerner, Climate sensitivity: Analysis of feedback mechanisms. American Geophysical Union, pp. Prall,Jacob Haroldand Stephen H.

4. A rational cost-benefit analysis of most global warming scenarios indicates that it would be cheaper and more effective to prepare to adapt to a warmer climate than it would be to try to prevent global warming.

All these thesis statements about global warming are of . Introduction. What exactly is global warming and why is it worthy of consideration? Global warming is the scientific phenomenon linking an increase of the average earth temperature because of a trapping of radiation within the earth like a greenhouse.

Dr. Ivar Giaever, a Nobel Prize-Winner for physics in , declared his dissent on man-made global warming claims at a Nobel forum on July 1, “I would say that basically global warming is a non-problem,” Dr. Giaever announced during his speech titled “Global Warming Revisited.

The geoid (/ ˈ dʒ iː ɔɪ d /) is the shape that the ocean surface would take under the influence of the gravity and rotation of Earth alone, if other influences such as winds and tides were absent. This surface is extended through the continents (such as with very narrow hypothetical canals).

According to Gauss, who first described it, it is the "mathematical figure of the Earth", a smooth.
