Tackling Climate Change
Former President of the US, Obama once said “But for the sake of our children and our future, we must do more to combat climate change”.
Climate change is becoming the biggest challenge of our time, spanning continents, countries generations and civilizations. The Earth is constantly heating at an alarming and unprecedented rate and the average temperature continuing to rise.
Two thirds of the global warming has occurred since 1975 at a rate of roughly 0.15 – 0.2 degrees Celsius per decade. Sadly, this change is believed to be permanently modifying the earth’s climate.
The main trigger is the greenhouse effect, which is increasing the amount of heat retained by the atmosphere hence causing the rise in temperature. Normally, the greenhouse gases present in the atmosphere block heat from being released, otherwise the temperature would have been around 33 degrees Celsius colder on average. Since the Industrial Revolution began and especially over the past 50 years, the Human activities, such as
deforestation and burning fossil fuels at a great rate, have contributed to an increased concentration of atmospheric CO2 along with other gases making the greenhouse effect worse.
