What is the Issue: International Importance
Global warming can cause many worldwide problems; there is a higher than 75% chance that if nothing is done about carbon emissions then global temperatures could rise between 2 and 3 degrees Celsius over the next 50 years and around a 50% chance that average global temperatures could rise by 5 degrees.
Around 40% of species could become extinct and there could be large amounts of coral bleaching leading to the destruction of coral altogether. Extreme weather conditions could cause global GDP to decrease by 1% and if temperatures rise by 2 or 3 degrees global economic output could fall by 3%.
However if temperatures were to rise by 5 degrees global output could decrease by 10% and poorer countries could loose more than 10% of their output which will exacerbate the already horrific famines and problems in poorer countries, but these problems may also spread to other countries throughout the world leading to extreme international problems.
