Since my childhood, I have been hearing the term ‘global warming’. But now after many years I could realize being terrified the very long term affect of it on to the climate. We had learned about ‘global warming’, ‘CFC gas’, ‘green house effect’, ‘carbon-di-oxide effect on climate’ from the beginning of our school life. But the matter of great regret, I couldn’t find anything now that resembles of being concerned about ‘Climate change’ of the earth.
Without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario. Even the lower end of this range would take the temperature increase since pre-industrial times above 2°C – the threshold beyond which irreversible and possibly catastrophic changes become far more likely.

Climate change is already happening and represents one of the greatest environmental, social and economic threats facing the planet. It is our dire necessity to save our planet “Earth” from the upcoming disasters right now. From personal initiative to Global Leaders’ combination of thoughts could make this effort and effective one. Bangladesh is a country which is in a threat. few inches increase of sea water level could cause huge area of land to disappear. We are to move forward to save us, our future generation.
The warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. The Earth’s average surface temperature has risen by 0.76° C since 1850. Most of the warming that has occurred over the last 50 years is very likely to have been caused by human activities.
Projected global warming this century is likely to trigger serious consequences for mankind and other life forms, including a rise in sea levels of between 18 and 59 cm which will endanger coastal areas and small islands, and a greater frequency and severity of extreme weather events.
Human activities that contribute to climate change include in particular the burning of fossil fuels, agriculture and land-use changes like deforestation. These cause emissions of carbon dioxide (CO2), the main gas responsible for climate change, as well as of other ‘greenhouse’ gases. To bring climate change to a halt, global greenhouse gas emissions must be reduced significantly.
In the past most changes were due to natural causes like Volcanic eruptions, continental drift, ocean currents and earth’s tilt but now human influence is a major cause of this change.Today when we talk about climate change it is about the changes caused in the environment because of human activity and that includes mainly greenhouse emissions. According to researchers, Methane concentration in the atmosphere has increased approximately 150% in recent times due to industrial pollution. Other major contributors are carbon dioxide from air pollution and nitrous oxide from fertilizers. All these greenhouse gases concentrated in the atmosphere beyond natural level cause global warming.
Bangladesh, regarded as one of the countries extremely exposed to climatic threats, has made its leadership visible in the global climate change negotiating process highlighting its ‘right to survival as a human being’, in recently concluded climate change talks in Bonn. In the meeting Bangladesh gave an outline of the structure of the proposed adaptation center to the Danish team, host of the final round climate change negotiation meeting in Copenhagen in December next.
Blog Action Day is an annual event that unites the world’s bloggers in posting about the same issue on the same day. The aim is to raise awareness and trigger a global discussion. I am joining to that stream with writing this blog post, hoping people will think of it at least for a while and do something right from now….
The day is not too far, when our descendant will curse us for our deeds on earth– to leave them an inharmonious, indiscipline climate. The earth will certainly be impossible to live. We are to be united to protect our mother earth from dangers… for a sweet,dreamy night for sleep of our future generations.Thanks to Solilo for her inspiration to write this post on this day.
Let all of us stand together, to save the earth, to save our next generations. Let us start it right from our side, from very silly thing in our house hold chores to national arena. May Almighty ALLAH be with us, bless us from the dangers..
Here are some other blogs who took part in the day’s action too:
