Block 4 – Lesson 1

CLIMATE AND VARIATION OF ATMOSPHERIC FACTORS

The climate of a place is determined by the data registered over several decades. It is closely related to temperature, humidity, rain, solar radiation, wind and atmospheric pressure.

Atmospheric phenomena, like electrical storms, thunder and lightning, are related to the climate as well. They are produced as a consequence of solar radiation, temperature variation, and atmospheric pressure.

Climate has a strong influence over the

characteristics and distribution of

vegetation, animals, and over people.

Air forms a layer around the Earth. It is a gas impossible to touch, but possible to feel when it moves. Earth’s rotation and revolution together with sunlight produce wind.

Climate variation has always existed as a consequence of different natural phenomena. However, these natural phenomena only partly explain global warming. Inadequate human behavior is also a factor.

Facts

Air forms a layer around the Earth. It is a gas impossible to touch, but possible to feel when it moves. Earth’s rotation and revolution together with sunlight produce wind.

Most scientists state that global warming is caused by an increase of greenhouse emissions produced by human beings in their daily and industrial activities.

Problems

The effects of global warming are becoming more and more visible: the melting of glaciers, the rise of sea levels, severe droughts, hurricanes and floods, the extinction of plant and animal species, and so on.

Problems

SolutionsSome alternatives to reduce the greenhouse effect and decrease global warming are:• Use natural light as much as possible.• Use energy saving light bulbs.• Unplug all electronic devices when they are

not being used.• Use green energy.• Walk, use a bike or public transportation.
