Planeet, Planet Zemlja, Planeta Terra, —, —, Planet Earth. In this vast universe of ours we know of no other place so hospitable to life in its infinite variety.
But today, climate change poses a clear and present danger. It threatens every species on earth. Increasing the number of extreme weather events that require international action. The time for leadership and meaningful initiatives is now!
As part of an intergovernmental effort under UN (United Nation) leadership, the world’s top scientists have concluded that the climate is changing. And they have issued urgent warnings about the future we can’t afford to ignore. The IPCC reports leave no room for doubt: global warming is a fact! And human activity, including the burning of fossil fuels, industrial emissions and deforestation, are the main cause of climate change and it’s most dangerous side effects.
The dramatic rise in greenhouse gases over the last 250 years, particularly carbon dioxide has caused temperatures to rise across the globe and this warning is rejected to accelerate at an alarming and dangerous base. Science is a powerful witness.
Our world is undergoing a dramatic transformation. Dangerous atmospheric changes already observed in measure and will continue for decades. Changes and preservation patterns will intensify drought in some areas and aggravate flooding in others. And as the world’s glaciers disappear and the oceans heat up, global sea levels may rise between 18 and 59 cm by the end of the century. The shrinking of Greenland’s ice sheets and a large scale of loss of ice of Antarctica could accelerate the problem with unpredictable speed. Small island nations already victimizing by increasing storm surges, and beat erosion could one day be lost to the sea. As climate change disrupts nature’s balance, biodiversity suffers. In the oceans and on land, all of earth’s species are threatened. Some may disappear forever.
Climate change could potentially compound growing population pressures on food supplies. Over the produlent in many places, over the long term, worldwide agriculture yield will likely decreases drastically in all regions. And as always: the poorest among as are the most vulnerable. Rainfed Agriculture could drop 50 % by 2020 in some African countries. Increasing malnutrition and a need for emergency aid.
Nearly 1/6 of the world’s people rely on mountain glaciers for drinking water. Crucial supplies which are expected to decline significantly as these glaciers melt away. 44 % of the world’s people live within 150 km of the coast and will be exposed to more frequent and more destructive storms and coastal flooding and rising sea levels which may overtime in andate lowlines countries, islands and cities;
Cities like Alexandria, Calcutta, Dhaka, Bangkok and Shanghai, homes to hundreds of millions of people. We will have to adopt. Regions that bear the least responsibility for what is happening will be among the hardest hit.
We can shape a different future. The IPCC’s reports that have been endorsed by more than over 50 countries offer a range of options for moving forward together. Solutions exist – but there is no time to waste. First we must stabilize global greenhouse gas emissions. Then, according to the world’s scientists, we could limit the rise in global temperature to 2° C and prevent the most severe impacts of climate change. If the world reduces its emissions by approximately 2/3rd by the year 2050.
This must be a global effort and with real leadership it can be done. All of us must change our consumption patterns. Improved conservation and energy efficiency could help enormously without requiring nature expenditures. But it’s largely up to governments to ensure that the right choices are available and attractive. Like more efficient modes of transportation and better building coats. Better management of our forests can also clear a vital role, hoping the planet to heal itself by drawing carbon dioxide out of the atmosphere.
The IPCC also suggests we change the way we think about energy. The cost of fossil fuels should reflect their long-term impacts on climate change. A price on carbon emissions would encourage the development of alternative energy resources and that would help developing countries choose a more environmentally sustainable course.
We must act together and we must act now! One way or another, the earth will survive. By acting together, the world’s leaders can ensure that we will too. And that the planet we leave behind for our children will be a place where they can thrive.
