Atmospheric helium levels are on the rise

Physics World

Levels of helium-4 in the Earth’s atmosphere have been increasing since at least 1974, according to a study by researchers at the University of California, San Diego, US that resolves a longstanding anomaly in atmospheric science. When the gas is extracted and burned, the helium is released into the atmosphere.

Climate Change and the Hard-Headed Realist

Legal Planet

It will require us to fundamentally alter the profile of our energy use and derive growth from fuels and technologies that emit less carbon dioxide into the atmosphere, and to adapt to the climatic changes that our actions are too late to prevent.” “Climate change also promises to impact the global economy.

Now-Justice Breyer argued that it was misleading to consider the environmental impact of nuclear power without also considering the impact of alternatives such as coal. There were a few more mentions of climate change in 1983.

Union of Concerned Scientists

Moreover, there are steps policymakers can take to prepare for these spring weather phenomena and bolster the reliability and resilience of the US power system. Power lines – Floods can saturate soil and make trees more likely to uproot and fall onto power lines.

Solar energy is superior to nuclear for powering crewed mission to Mars, show scientists

Frontiers

The main source of power for some NASA Mars rovers comes from a multipanel solar array. But, in the last decade or so, most people had assumed that nuclear power would be a better option than solar energy for human missions, according to co-lead author Aaron Berliner, a bioengineering graduate student in the Arkin Laboratory at UC Berkeley.

Why nuclear energy must be part of ‘net zero’ climate targets

Physics World

Those findings might surprise physicists, who will be aware that the energy density of nuclear fission is so high that just a fingertip of uranium has an energy equivalent of 5000 barrels of oil. Indeed, it is understandable why people might fear radiation given that you can’t see it – yet the same can be said of the air that we breathe.
