The ocean's food chain is at risk
We were one of the first to call attention to the acidification of the oceans. The oceans take up a huge amount of carbon dioxide from the atmosphere every year. A portion of that carbon gets turned into carbonic acid, so that the more carbon dioxide there is in the atmosphere, the more acidic the oceans become. The oceans are now 30 percent more acidic than they were before the Industrial Revolution. It's the most chilling change I've seen in my professional career. If it continues, tiny organisms at the base of the food chain will have their shells dissolve while the animals are still alive. It will

Look at the crisis as an opportunity
I think the debate about the climate crisis in this country has been framed the wrong way. We've been talking about it from the perspective of the cost to society, rather than the point of view of the opportunity for profit. People are missing that this is a $4 trillion market for energy, and that's before we factor in the supply-demand imbalances that will occur as China and India ramp up their energy use. There is both a climate crisis and an impending energy crisis, and as Stanford economist Paul Romer has said, a crisis is a terrible thing to waste. Energy is just the capacity to do work, and work is what creates economic output. I'm not against

Energy efficiency is the ultimate answer
If we're going to survive global warming, there are two things we must do. We have to move in the direction of renewable energy, such as wind and solar power, and we have to improve energy efficiency. You can measure it in different ways-passenger miles per gallon of gas, lumens per watt-but we need to think in terms of doubling efficiency. Not "conservation," which implies sacrifice. Efficiency doesn't involve sacrifice. If you compare a modern refrigerator with one from 1973, which was the year of the OPEC oil embargo, it's bigger, it's gotten rid of CFC refrigerants, its inflation-adjusted price is two thirds less-and it uses 75

Our Solar System is seeing vast alterations in its planets, obviously including that of Earth. As our solar system continues its swing around galactic center it has entered a higher density of energy. This higher density of energy is causing ‘transformations' of all our planets including the sun.
These dramatic changes have been and are currently being studied by top scientists around the world. Unfortunately the news media of the world refuses to run stories to educate the people of the world as to what is actually occurring. It is of extremely

Sustainability? I don't believe there is such a thing anymore. If we were to sustain our current rates of consumption, habitat destruction, emissions, etc. the Earth's biosphere will collapse within a century.

The concept of sustainability at this point is flawed. It is now not a matter of "sustainability", it is a matter of retreat. We need to drastically reduce consumption, drastically reduce emissions, halt all critical habitat destruction, reduce an exponentially growing human population, end industrial pollution, end the expense of war in both monetarily and human life, and educate the world.

We need to rebuild a vast network of environmental habitats linked continuously throughout continents. We need to dive headlong into clean
