Climate change, greenhouse effect and global warming - in the 21
Century there is hardly a topic that is discussed as ubiquitous and
"hot". Convinced skeptics of human-induced climate change refer to
epochs of geological history, in which the Earth is heated strongly,
even without our help or cooled. Also they see a future climate change
due mainly of course, among other things, by a modified elliptical
orbit like the Earth around the sun. Climate scientists argue that it
is today but also a significant human contribution to greenhouse gases
in the atmosphere, which will provide added that the earth is warming
up to the end of this century by a few degrees Celsius. The reason for
this is especially the industrial and technological development over
the past 150 years. Climate change and CO2 emissions, however, were
not initially known. They moved only gradually, increasingly from the
1960s into the public consciousness.
