![Accelerated Global Warming 14 October 2020 James Hansen and Makiko Sato In the past five years global temperature has jumped well above the trend which has been stable at about 0.18°C per decade for the past half century (see figure above). This deviation is too large to be explained by unforced climate variability. The immediate suspect is human-made greenhouse gases and amplifying climate feedbacks, but that explanation does not work. Yes, the growth rate of the greenhouse gas (GHG) climate forcing has experienced a disturbing uptick in the past several years (Fig. 2), starkly inconsistent with global pledges to reduce emissions, creating an enormous burden for today’s young people.[1] However, there is another variable forcing that is being measured accurately: solar irradiance. - Dr. Hansen](https://wp.nyu.edu/gw/wp-content/uploads/sites/9873/2020/10/Screen-Shot-2020-10-14-at-12.24.58-PM-858x1024.jpg)
