A key issue for mitigation technology is providing data to show what is really happening. This reveals an albedo crisis, an accelerating darkening of the world, now faster than 1% per decade. The retention of each additional watt per square metre causes significant warming. This aspect of climate science is not broadly discussed or understood.
Here is a chart that climate scientist <https://twitter.com/LeonSimons8/status/1717898452338643252> Leon Simon made from <https://ceres.larc.nasa.gov/> NASA CERES satellite data to show the accelerating heat retention caused by the albedo crisis. It shows increase of one watt per square metre over about 14 years from 2003 to 2017. The speed has since more than doubled, with the next watt taking only 6.5 years. This problem results from loss of snow, ice, aerosols and other reflective planetary surfaces. These accelerating feedback processes can only be mitigated by deploying technology to brighten the planet. Unfortunately, action on carbon is too small and slow to make any difference to these planetary tipping elements, showing the climate policy focus has to shift from carbon to albedo.
