Physicists consider their own carbon footprint
In October's issue of Physics World, Phil Marshall, an astrophysicist at the University of Oxford, calls on physicists to pull their weight when it comes to climate change, drawing on his own research showing that astronomers average 23,000 air miles per year flying to observatories, conferences and meetings, and use 130 KWh more energy per day than the average US citizen.
Marshall says that physicists must not only act as "trusted voices" in climate-change debates, but also do all they can to reduce their own carbon footprints.
This must involve a change of behaviour at the individual level – say by skipping an overseas scientific meeting and taking part via video conference call instead – and as an entire community, particularly by carefully planning future experiments to try and make them as "carbon-neutral" as possible.
"Individual physicists can help to solve the energy problem, and not just the ones whose research is in new technologies; we can all contribute by setting the right example," writes Marshall.
It is an urgent problem for physics as many current "big-science" facilities – from huge particle accelerators to massive ground-based telescopes – have a frightening energy demand, Marshall notes. CERN's Large Hadron Collider, for example, has an energy bill as big as that of all the households in the region around Geneva, estimated to be around €10m.
Marshall's comments are timely as researchers are set to meet up in mid-October to identify ways to do large-scale physics research with a reliable, affordable and sustainable energy supply that is carbon-neutral.
The venue of this workshop – Lund, in Sweden – is an appropriate location for the meeting as the city will also play host to the first ever carbon-neutral, big-science facility – the €1.48bn European Spallation Source (ESS) – which is set to come online towards the end of the decade. All of the ESS's electricity will come from renewable sources and more than half the heat it generates will be fed back into the system.
Carbon reduction is, of course, not the only challenge facing those designing massively complex scientific facilities like the ESS. As explained in the first ever Physics World big-science supplement, which accompanies the October issue of the magazine, these challenges are many and varied – ranging from the financial and technical to the political and scientific.

It is an excellent suggestion!
It would also get astrophysicists out of their "ivory towers" into the world of ordinary citizens.

The unscientific, naive, and unnatural way is to just expect people to orchestrate their lives as if they're less relevant than the common good ,... while the scientific, realistic, and natural way is to find a means of taking advantage of the great force that is free individual self interest to reduce co;, by use of technology in making the cheapest energy source also more efficient than oil/coal.

This seems to be a complete reversal of policy at Nature magazine, which banned me from posting comments on reports published there after I publicly called for the resignation of the editor, Dr. Philip Campbell, for publishing misinformation about the influence of Earth's heat source - the Sun - on Earth's changing climate.
Dr. Campbell and NPG were sent copies of this note for their response.

The reason you were rightly banned is that you post conspiracy myths and scientific nonsence such as your assertion that the sun ha a Neutron Star inside it or some sort of nonsence like that.
