IS GLOBAL CLIMATE CHANGE MAN-MADE?

ACCORDING TO SCIENTIFIC STUDIES, THE GLOBAL CLIMATE OF THE EARTH HAS

CHANGED SEVERAL TIMES IN THE HISTORY OF OUR PLANET.

IT IS KNOWN THAT IN THE PAST, THE RISING OF TEMPERATURES HAS

HAPPENED BECAUSE OF A NATURAL PROCESS CALLED GREENHOUSE

EFFECT, BUT THE INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE

(IPCC) CLAIMS THAT IN THE LAST 50 YEARS, MOST CAUSES FOR GLOBAL

CLIMATE CHANGE HAVE BEEN MAN- MADE.

TO START WITH, THE RISING OF CO2 HAS BECOME FASTER AND FASTER EVER

SINCE THE INDUSTRIAL REVOLUTION STARTED, OWING TO HUMAN ACTIVITIES

SUCH US FOSSIL FUEL BURNING AND CLEARING OF FOREST

SECONDLY, WITH REGARD TO THIS FACT WE HAVE TO REMEMBER THAT THE CARBON

DIOXIDE TRAPS THE EARTH’S RADIATION, CALLED INFRARED RADIATION, IN OTHER

WORDS, HEAT.

AS A CONSEQUENCE, HUMAN ACTIVITIES ARE PROBABLY

INFLUENCING THE CLIMATE CHANGE

WE ARE GOING TO REMEMBER THE GREENHOUSE EFFECT

NEVERTHELESS, SOME SCIENTISTS AND MEDIA RECKON THAT

NOWADAYS, THIS IS A NATURAL PROCESS, ALTHOUGH IPCC AND

COUNTRIES WHICH HAVE SIGNED THE KIOTO PROTOKOL ARE

ASKING US TO REDUCE THE CARBON DIOXIDE EMISSIONS.

WHAT IS MORE,IPCC GIVES US SCIENTIFICS REASONS

WHEREAS THE FORMER SCIENTISTS ONLY SHOWED

FINANCIAL CONSIDERATIONS

THAT IS WHY THIS ISSUE IS CONSIDERED TO BE AN OPEN

DISCUSSION . HOWEVER, FROM THE POINT OF VIEW OF MANY SCIENTISTS, IT IS TIME WE FINISHED THIS

ARGUMENT.

LAST BUT NOT LEAST, “GLOBAL WARMING” IS JUST THE TIP OF THE

ICEBERG AND THE TERM “CLIMATE CHANGE” IS BECOMING MORE

AND MOR COMMON AS THERE ARE ACTUALLY OTHER CHANGES IN

ADDITION TO RISING TEMPERATURES

IN CONCLLUSION, WARMING IS EXPECTED TO CONTINUE FOR A

LONG TIME EVEN IF EMISSIONS STOP. ALL THINGS CONSIDERED,

PEOPLE HAD BETTER THINK ABOUT THE FUTURE.
