She stops next to a pair of railroad-like tracks and removes
the tool attached to the end of her arm. The move is
practiced and professional, like a cook changing the tool on
a set of egg beaters. First, she inserts the existing tool
into a lock on her opposite arm which holds it while she
disengages the tool. Next, she selects the next tool f

1.1 What is Global Warming?
Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °°C(1.4°°F), with about two-thirds of the increase occurring since 1980. Warming of the climate system is u
Seriousness of Climate Change
Temperatures around the world have increased -> melting glaciers and rising sea levels
Change of habitats, wildlife, cultures, artifacts and the life of humans.
changes in ecosystem, rainfall, desertification. -> flood, drought, typhoons, yellow dust, heat wave
Seriousness of Climate Change
-Temperatures around the world have increased -> melting glaciers and rising sea levels
-Change of habitats, wildlife, cultures, artifacts and the life of humans.

temperature has risen steadily.
Why Global Cooling happened?
Global warming → glaciers in each pole solve

Effects of global warming
There are two major effects of global warming:
Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100.
Rise of sea levels by at least 25 meters (82 feet) by the year 2100
Nowadays, ‘eutrophication’ presents as one of the most serious ecological problems of open water sources such as lakes, oceans and reservoirs. It can be occurs naturally over centuries as lakes age and filled in with sediments, or acid rain. However, it has been rapidly increasing caused by human activities like fertilizers, municipal sewage, and wastewater from the factory. The Baltic Sea is

The altitude is the actual height of an object above mean sea level(MSL).
On the ground, true altitude will match indica
surfaces. Foils of similar function designed with water as the working fluid are called hydrofoils.
The lift on an airfoil is primarily the result of its angle of attack and shape. When oriented at a suitable angle, the airfoil deflects the oncoming air (for fixed-wing aircraft, a downward force), resulting in a force on the airfoil in the direction opposite to the deflection. This force is kn
