Global Warming

Global warming refers to the observed since the mid-19th century rise in the average temperature of the near-earth atmosphere and the oceans . The calculated warming trend over the past 50 years in the amount of 0.13 ° C per decade (from 0.10 to 0.16 ° C) is almost twice as large as that over the last 100 years. This

Atmospheric Pressure

Atmospheric pressure is the force per unit area exerted by the air on the earth’s surface. The atmospheric pressure at a point coincides numerically with the weight of a static air column unit extending straight from the center to the top section of the atmosphere. As the density of air decreases with height, you can not calculate that weight unless

Atmospheric temperature

Atmospheric temperature is called one of the constituent elements of climate refers to the degree of specific heat of the air in a certain place and time as well as the temporal and spatial evolution of that element in the different climatic zones. Element is the weather more important in delimiting most climate types. For example, when referring to macrothermic

Climate Change

Climate change, or climate variability, refers to the change of climate on the Earth and Earth-like planet , regardless of causes, whether natural or human. The current, caused mainly by human global warming is an example of a climate change. A climate change may indicate a cooling or warming over different time periods. The term climate variation sometimes referred specifically
