Is the threat of global warming real.

This essay has presented Earth’s many changing faces during its journey. Earth had molten beginnings, was , and may have . Later, and and . Earth experienced swings from to conditions as atmospheric gases dramatically changed, continents moved, and vast and of complex life played out on land and sea. But the changes happened over timescales of millions and billions of years, not hundreds. No climate scientist will deny that carbon dioxide traps infrared radiation and warms Earth’s atmosphere. The vented enough carbon dioxide into the atmosphere to create 200 million years of Greenhouse Earth conditions, when reptiles ruled Earth. Volcanism waned and around 150-to-100 mya. By 35 mya, and the Antarctic ice sheet began forming. Every paleoclimate study I have seen places greenhouse gas (and primarily carbon dioxide) concentrations as the primary determinant of global surface temperatures, after the Sun's radiation, but the Sun's output is considered to have been exceptionally stable and has risen slowly over the eons. , usually by accentuating the carbon dioxide with a positive feedback effect that may have reached runaway conditions at times.

That problem goes by the name of global warming.

 In order to talk about global warming, we must first learn what causes the greenhouseeffect.

What does the greenhouse effect have to do with global warming.

In his , Charles Darwin sketched processes by which species appear and disappear, today called speciation and extinction. is a landmark in scientific history and is still immensely influential. But it was also afflicted by false notions that are still with us. Europe’s emergence from dogma and superstition has been a long, fitful, only partially successful process. In the 1500s, Spanish mercenaries to the unfortunate Indians that they conquered and annihilated that stated that Creation was about five thousand years old, as scholars of the time simply added up the “begats.” The is filled with tales of genocide, miracles, and disasters, with a global flood that the faithful survived. As geology gradually became a science and processes such as erosion and sedimentation were studied, the Judeo-Christian belief of Earth's being five thousand years old and the concept of arose in Europe.

This is the question of global warming.

are created by undisturbed organism remains that become saturated with various chemicals, which gradually replace the organic material with rock by . Few life forms ever become fossils but are instead consumed by other life. Rare dynamics lead to fossil formation, usually by anoxic conditions leading to undisturbed sediments that protect the evidence and fossilize it. Scientists estimate that only about 1%-2% of all species that ever existed have left behind fossils that have been recovered. Geological processes are continually creating new land, both on the continents and under the ocean. Seafloor strata do not provide much insight into life’s ancient past, particularly fossils, because the process in “mere” . The basic process is that, in the Atlantic and Pacific sea floors in particular, oceanic volcanic ridges spew out basalt and the plates flow toward the surrounding continents. When oceanic plates reach continental plates, the heavier (basaltic) oceanic plates are subducted below the lighter (granitic) continental plates. Parts of an oceanic plate were more than 100 mya and left behind plate fragments. On the continents, however, as they have floated on the heavier rocks, tectonic and erosional processes have not obliterated all ancient rocks and fossils. The oldest “indigenous” rocks yet found on Earth are . have been dated to 3.5 bya, and fossils of individual cyanobacteria have been dated to 1.5 bya. There are recent claims of finding . The oldest eukaryote fossils found so far are of . The first amoeba-like vase-shaped fossils date from about 750 mya, and there are recent claims of finding the first animal fossils in Namibia, of sponge-like creatures which are . Fossils from might be the first animal fossils, and some scientists think that animals may have first appeared about one bya. The first animals, or , probably descended from . The is a tail-like appendage that protists primarily used to move and it could also be used to create a current to capture food. Flagella were used to draw food into the first animals, which would have been sponge-like. When the first colonies developed in which unicellular organisms began to specialize and act in concert, animals were born, and it is currently thought that the evolution of animals probably only happened . In interpreting the fossil record, there are four general levels of confidence: inevitable conclusions (such as ichthyosaurs were marine reptiles), likely interpretations (ichthyosaurs appeared to give live birth instead of laying eggs), speculations (were ichthyosaurs warm-blooded?), and guesses (what color was an ichthyosaur?).

Global warming is widely believed to be the main cause of rising average global temperatures.
Warmer temperatures willcause a greater amount of evaporation from lakes, rivers, and oceans.

One huge impact of global warming is the change in animals’ habitats.

We know a great deal about atmospheric physics, and from the onset, many of the claims were just plain fishy. The extreme haste with which seemingly the entire world immediately accepted the idea of Anthropogenic ( man-made ) Global Warming made us more than a little bit suspicious that no one had really taken a close look at the science. We also knew that the catch-all activity today known as "Climate Science" was in its infancy, and that atmospheric modeling did not and still does not exist which can predict changes in the weather or climate more than about a day or two in advance.

Scientists believe that awarming of only 6 degrees would cause glaciers to melt at a high rate.

Global warming is considered as a byproduct of energy crisis, because as oil continues to burn in the refining process, CO2 is constantly emitted to the atmosphere at a fast rate and in heavy concentrations, which in turn, worsens the global warming situation.
