Amending the Montreal Protocol

UN Kigali Amendment Boosts Global Environmental, Climate Change Prospects

National representatives to the UN Montreal Protocol took action to phase out production and use of hydrofluorocarbons (HFCs) at a meeting in Kigali, Rwanda this past week. In addition to further reducing destruction of atmospheric ozone, the Kigali Agreement is expected to reduce projected mean global temperature rise 0.5 degrees Celsius over the course of the century.

Sea Level Rise is Far Worse Than Previously Thought

Rising levels of greenhouse gasses are increasing global temperatures and this is causing sea levels to rise. Global warming causes sea levels to rise by melting ice sheets, glaciers, and sea ice; it also causes water to warm and expand. Sea-level rise and resultant flooding may be the greatest challenge facing humanity. Scientists agree that sea levels will rise and…

In the spirit of Paris - COP21

The Art of the Possible: Paris Agreement Comes Into Force

The mood in Paris last December was unmistakable, the optimism palpable. After decades of gridlock and disappointment, the negotiation at the COP21 climate conference held to its promise of progress.

The first round of emission reduction targets agreed to at COP21 are laudable, but climate scientists tell us that we must be even more ambitious.  Even if all nations achieve the emissions reduction targets contained in the Paris Climate…

Trump, the U.S. elections, and climate change. A pivotal moment

U.S. Elections are a Pivotal Moment for Climate Change Policy

Dean Scott, the senior climate change reporter for Bloomberg, moderated a panel discussion this weekend at the 2016 conference of the Society of Environmental Journalists. The topic at hand was the upcoming U.S. elections and what it means for climate change policy, particularly if Donald Trump wins the presidency. You might think that his position on climate change is “typical”…

An early conceptual drawing of NASA Space Solar Power

NASA and a Solar Revolution

It’s no secret that the Earth is in dire need of clean energy alternatives to fossil fuels. The source of that clean energy, however, doesn’t necessarily have to be on Earth. The Space Solar Power Initiative (SSPI) is a team of scientists from Caltech that includes researchers from NASA’s jet propulsion laboratory. These scientists propose building the largest-ever space structure…
