WHAT IS CLIMATE CHANGE?
Climate change is the greatest threat facing our planet today. A warming planet alters weather patterns, water supplies, seasonal growth for plants and a sustainable way of life for us and the world’s wildlife. Climate change has already started, but it’s not too late to take action. There’s still time for us all to be part of the solution.
HOW DOES CLIMATE CHANGE OCCUR?
A continuous flow of energy from the sun heats the Earth. Naturally occurring gases in the atmosphere, known as greenhouse gases – this includes carbon dioxide (CO2) - , trap this heat like a blanket, keeping the Earth at an average of 15 degrees Celsius – warm enough to sustain life. The overuse of fossil fuels is increasing CO2 in the atmosphere, trapping more and more heat and warming the Earth.
As a result, we’re seeing more dramatic weather patterns across the globe resulting in devastating natural disasters and shrinking the world’s ice shelves and glaciers due to warming sea water. Because ice acts as a solar reflector, the less ice there is, the less heat the Earth reflects. WWF provides more detail on the impacts of climate change on our polar regions, glaciers and more.
Why is climate change happening?
There’s more than a 90% probability that human activities over the last 250 years have warmed the planet. That’s according to the 2007 Assessment Report by the United Nations’ Intergovernmental Panel on Climate Change – an organisation made up of thousands of independent scientists worldwide. Likewise, WWF’s Living Planet Report, concludes that humanity’s overconsumption of food, material goods, fossil fuels, and non-renewable resources is putting a huge toll on the planet, exceeding its capacity to sustain us. Forests absorb and remove CO2 from the atmosphere. So areas undergoing excessive deforestation experience higher carbon emissions. Agriculture is the second largest greenhouse gas emitter after fossil fuels. Methane produced by livestock, manure management, the burning of savannah, and the conversion of forests to pasture land are all major sources of greenhouse gas emissions. WWF details the environmental impacts of agriculture on climate change, water supplies, habitat loss and more.
How can we be more sustainable?
Although the journey to a sustainable future may seem difficult to imagine, it is far from impossible. We can all do our part individually and together. WWF’s Energy Report provides a realistic scenario of what the world could be like in 2050, running wholly on renewable energy.
We can celebrate our planet one day a year for Earth Hour – and go Beyond the Hour towards a sustainable future.
