How 6 degrees can change the world?
By the year 2100, many scientists believe that the Earth’s average temperature could rise by as much as six degrees Celsius. In a compelling investigation, National Geographic Channel leads a degree-by-degree journey to explore what each rising—and critical—degree could mean for the future of our people and planet.
What two things do all climate scientists agree on Six Degrees Could Change the World?
Six Degrees Could Change the World In 4 decades all the glaciers on the Himalayas the source of water for millions, could be gone. By the end of this century the Amazon rainforest, home to half the world’s Biodiversity , could whither to a dry savannah.
What could happen to the global climate by the end of the century?
Even if the atmospheric composition of greenhouse gases and other forcing agents was kept constant at levels from the year 2000, global warming would reach about 1.5℃ by the end of the century. Without changing our behaviour it could increase to 3-5℃ by the end of the century.
What were conditions like when the globe’s average temperature was 6 C cooler than today?
1.) When scientists talk about a change of 6°C globally they are not referring to fluctuations in daily temperatures but to a global average change. What were conditions like when the globe’s average temperature was 6°C cooler than today? The Earth was in the grip of an Ice Age around 18 000 years ago.
What happens if the Earth warms 6 degrees?
If the world’s temperature increases by six degrees, rainforests will be deserts and massive numbers of migrants will flock to the few parts of the world they see as inhabitable, resulting in racial conflict and civil war.
What is the temperature rise possible over the next century?
The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
What happens when temperature rises 6?
What will happen if the Earth warms?
If warming reaches 2 degrees Celsius, more than 70 percent of Earth’s coastlines will see sea-level rise greater than 0.66 feet (0.2 meters), resulting in increased coastal flooding, beach erosion, salinization of water supplies and other impacts on humans and ecological systems.
What happens if a planet is too cold?
When a planet gets cold enough, that body turns into a snowball world, a rocky object covered in ice. Ice and snow are bright and reflect much of a star’s heat back into space, causing the world to cool down even further.
