The Tipping Point
By Shahir Masri - 3/26/17
If you’ve heard of climate change, you’ve probably heard of the “tipping point.” But what does this mean? To understand, you must first understand earth’s “positive feedback” systems. Let me explain.
Carbon, Temperature & Geologic History
By Shahir Masri - 1/5/17
Over my last two blogs, we discussed climate variation driven by natural phenomena such as the physics of the earth and sun, as well as greenhouse gases (GHGs). While both play key roles in climate change, it has hopefully become clear that on the time scale of present day climate change, it's GHGs and not natural phenomena that are steering the ship. This is the science. Not the politics.

In my last blog, I talked about greenhouse gases (GHG) as an important driver of climatic variation. Well, what about natural variation? Earth's temperatures have gone up and down in the past, so what if the current warming trend is just part of a natural cycle? Well, let’s discuss.
How Carbon Warms the Planet

In my last post I mentioned the launching of an educational blog series on climate change. Through this, I hope to inform the public on the science of the issue, its importance, and the ways in which we can each take action to help mitigate its severity. Absent of nuclear war, climate change represents the most threatening issue of our time. It affects national security, the economy, human rights, health and disease, wildlife, and more.
Fracking for Natural Gas: Why the Hype?
By Shahir Masri – 3/22/13
Natural gas (NG) refers mainly to methane (the simplest hydrocarbon), but can also include other gases born from the earth including ethane, propane, and butane. NG is just one of many sources of energy, others being coal, oil, nuclear, as well as “green” sources such as wind, solar, hydroelectric, and geothermal. Keep in mind that much of these raw resources are simply means of generating electricity, which is why electricity itself isn’t considered an energy source.
Hurricanes Harvey, Irma, & the Climate Connection
By Shahir Masri - 9/7/17
Recently, the world witnessed tragedy in Houston as Hurricane Harvey battered the Texas coast. Lives were lost, pets vanished, and entire neighborhoods were wiped out. It was just last summer that I visited Houston, staying at my friend’s gorgeous house. Through video last week I saw that house underwater. The very room I stayed in was a lake. My jaw dropped at the site. According to scientists, Harvey broke records, dropping more rain than any storm in contiguous U.S. history. To locals it was a nightmare. But did the storm arise by chance, or was there more to it?
