Sunspots are a magnetic phenomenon on the Sun.

The reason a sunspot appears dark is that they are cooler than the rest of the Sun's surface and also the gas inside the spot where the magnetic field is strongest is only emitting about 1/4 as much light as from the rest of the solar surface. 

The Kyoto Protocol is an international agreement linked to the United Nations Framework Convention on Climate Change, which commits its Parties by setting internationally binding emission reduction targets.

Recognizing that developed countries are principally responsible for the current high levels of GHG emissions in the atmosphere as a result of more than 150 years of industrial activity, the Protocol places a heavier burden on developed nations under the principle of "common but differentiated responsibilities."
