change is a scientific fact
Scientists are very
much in agreement that we have enough evidence of man-caused climate change and
the risks it brings to us. I am also sure that anyone with enough capabilities
and open mind will be convinced when reading enough scientific articles about the topic.
The issue is complex and there is not such a simple proof as for "two is greater than
Simply put, the
man-caused climate change is mostly due to burning of fossil fuels (a smaller
effect is cutting of forests, urbanization, cement industry etc.). In the industrial age since
1800s, we have burnt fossil fuels so much that simple balance would estimate
that the CO2 level would have risen from 280 ppm to 480 ppm. Instead, it has
risen only to 380 ppm, which is more than for millions of years.
The rest is in the
oceans affecting the coral reefs and ocean biology. I am pessimistic that we can
do too much. We will burn all our fossils and the ppm level will jump to 600
something and a lot will end up in the oceans. Fourier and Arrhenius already in
1800s predicted quite right the temperature rising effect of "carbonic acid" in
Those who deny that the
change in CO2 in the atmosphere from the preindustrial 280 ppm to current 380
ppm and projected ca. 600 ppm, which is due to human activities, have no effect
on climate or global temperature, deny the very basics of physics. They are like
creationists denying evolution.
Climate change is not necessarily global
warming. It may be local warming, local cooling, drought somewhere, more rains
Anyone can understand that human
activities have impact on waters, rivers, lakes and oceans. Why should air be
A man-caused (anthropogenic)
climate change is a scientifically proven fact. There is climate change and
global warming, but not necessarily warming everywhere. In some locations we may
see tiny ice age.
A great majority of scientists see climate
change as a very dangerous and potential threat. What is the solid proof that we
still have to wait before acting, and can we afford waiting without acting?
Cutting the carbon emissions is beneficial also in many other
Our fossil resources will last longer.
The extra oil you spend driving a SUV could be used by your grandchildren in
Dependence of Middle East would be
smaller. There would not be such a desperate need to attack other nations.
Not only atmosphere but also the whole
ecosystem of the oceans is adversely affected by the increasing CO2 content of
anthropogenic CO2 emissions
Volcanic eruptions are natural and in fact
they gave us carbon some billions of years ago for the start of life on earth.
The rest is carbon cycle in biosphere. Anthropogenic carbon dioxide emissions
are caused by burning of fossil fuels, and they are an extra load to atmosphere
and biosphere. Now there is some 40% more
CO2 in the atmosphere than in preindustrial era, and the increase will be 100% during this century.
