Visualize this

The earth is warmed by energy from the sun and the warmed earth releases heat. Greenhouse gases in the atmosphere such as CO2 absorb the heat and return it to earth, maintaining the temperature of the earth at an average of around 15 degrees. However, due to increases in CO2, the earth is becoming hotter. – from a PPT presentation on Activity of Team Minus 6% for Prevention of Global Warming by Kenji Someno (Lifestyle Policy Office, Global Warming Division, Global Environmental Bureau, Ministry of the Environment Government, Japan)

Who cares, really? I think everyone. This has always been everyone’s business. There's been too much noise created on this. Forget about the politics and the motivations of people who do. At then end of the day, they help send the message across.

I think all these noises fall under the label of "call for action". Some of the sound might be grating to the ears at times but at least, they often succeed in waking people up.
