Climate change: Is solar radiation management a feasible idea?
In an op-ed piece published in this newspaper on August 27, 2019, I discussed a number of methods within the context of Solar Radiation Management (SRM) as a way of mitigating some of the impacts of climate change. They are whitening low-level clouds, thinning the Cirrus clouds, injecting sulphate aerosols into the stratosphere, or putting sunshades (mirrors and/or reflectors) in outer space.

Solar radiation management can help combat climate change
In the Environmental Physics course that I teach from time to time, a student once remarked that we really do not have to worry about the deleterious effects of climate change because technology would be able to solve all the problems we are facing.

America’s ‘Last Frontier’ is slowly becoming the ‘Lost Frontier’
Nick-Named the “Last Frontier”, Alaska is the largest state (in area) of the United States.

The state is home to a vast expanse of pristine wilderness, towering mountains, breathtaking glaciers and big game animals.

Why thorium is a safer nuclear option
The picture is crystal clear. Human activity will soon drive the climate crisis all across our planet to the tipping point unless we rapidly transform the ways in which we produce and consume energy. While renewable energy technologies and energy efficiency measures can help dramatically cut emissions of greenhouse gases, they are not the panacea for the climate change related problems that we have created.
