Global Climate Change-CMC

  1. 1. GLOBAL CLIMATE CHANGE CMC 1º BACHILLERATO IES SALVADOR RUEDA (MÁLAGA) Mª LUISA SÁNCHEZ MARTÍN
  2. 2. 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.
  3. 3. 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.
  4. 4. 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
  5. 5. 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.
  6. 6. AS A CONSEQUENCE, HUMAN ACTIVITIES ARE PROBABLY INFLUENCING THE CLIMATE CHANGE
  7. 7. WE ARE GOING TO REMEMBER THE GREENHOUSE EFFECT
  8. 8. 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.
  9. 9. WHAT IS MORE,IPCC GIVES US SCIENTIFICS REASONS WHEREAS THE FORMER SCIENTISTS ONLY SHOWED FINANCIAL CONSIDERATIONS
  10. 10. 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.
  11. 11. 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
  12. 12. 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.
