400 ppm

If the rate of carbon emission continued, human will be facing the biggest disaster in history within 25 years. Last week carbon emission level recorded 400 ppm at Manua Loa, Hawaii for the first time in human history, a million times faster than expected. When we reach the level of 450 ppm, our iceberg at North pole will melt faster, sea level will accerelate, ecological system will be damaged and the human exsitance is in doubt as temperature will increase 2 degree celcius higher. So, what should we do? I believe many are business as usual as the environmental cost is perceived as too vogue and general. For people who can afford, paying extra for air conditioned electricity bill is a peanut. For those who cannot afford, it is the least they can afford to do but leave it to others for assistance. Unless human comes to common understanding and feel the crisis is real, I presume nothing radical will take place.
