I love plays that have musical moments. I'm not a big fan of musicals per se, but I love straight plays that have musical edges to them. I don't know if I will ever be able to structure a musical, but 'Finer Noble Gases' is as close as I've gotten.

Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature.

As we pump greenhouse gases into our atmosphere, the ocean absorbs carbon dioxide, making the seawater acidic and hostile for shellfish and corals.

Since stepping down as laboratory director in 1999, I have devoted an increasing fraction of my time to international issues. I am involved with energy, environment, and sustainability issues, particularly as they involve new energy sources free of greenhouse gases.

The fundamental importance of the subject of molecular diffraction came first to be recognized through the theoretical work of the late Lord Rayleigh on the blue light of the sky, which he showed to be the result of the scattering of sunlight by the gases of the atmosphere.

Many people believe the whole catastrophe is the oil we spill, but that gets diluted and eventually disarmed over time. In fact, the oil we don't spill, the oil we collect, refine and use, produces CO2 and other gases that don't get diluted.

On some issues, Republicans and Democrats disagree so sharply that compromise is nearly impossible. Republicans are not going to support a cap-and-trade program to limit greenhouse gases, and Democrats won't support a 1,000-mile wall on the border with Mexico.

Neglecting clean energy sources such as solar, wind, and especially nuclear, can result in blackouts, increased power bills, and will take a heavy toll on our efforts to reduce greenhouse gases.

I stick to stuff I'm pretty sure of and I know this: when the price of a barrel of oil is under $80 a barrel and you build a pipeline, you are driving up greenhouse gases.
