In 1988 James Hansen, a NASA scientist, testified before Congress that burning fossil fuels–coal, gas and oil–was warming the earth. At first the statement was met with scepticism, and public relations people from industry began actively sowing doubts about it. Yet, warm year followed warm year, until 2007 marked a watershed moment. Last year the earth experienced a dramatic surge in methane, a heat-trapping gas, from the melting permafrost that was accelerating further thawing. That same year the Northwest Passage stayed open all September for the first time in history.
Scientists now believe the earth has reached its “tipping point” for Arctic ice, which means the physical world on its own is taking command of the process that humans began. Some scientists predicted all Arctic summer ice would be gone by 2070, but now other scientists have revised the schedule for possibly 2012!
Further, the science community recognizes that the earth verges on crossing similar thresholds governing the reliability of monsoons, the acidification of the oceans, the availability of water from alpine glaciers and the actual level of the sea.
For the past one thousand years the amount of carbon dioxide in the atmosphere hovered around 275 ppm (parts per million), but with the Industrial Revolution and the accelerated burning of fossil fuels that number started to rise. Twenty years after testifying before Congress James Hansen with several coauthors published their latest findings saying to preserve a planet capable of sustaining civilization, the amount of carbon dioxide must “be reduced from its current 385 ppm to at most 350 ppm.” Standing at 385 ppm, the level of carbon dioxide is growing by more than 2 ppm annually!
John Paul II reminded us in early 1990: “Today the ecological crisis has assumed such proportions as to be the responsibility of everyone...I wish to repeat that the ecological crisis is a moral issue.”
When the great tsunami hit Southeast Asia on December 26, 2004, a quarter of a million people died. In its aftermath, survivors were amazed at how few dead animals lay among the debris. Stories surfaced that hours before the deadly “Harbor Wave” struck, animals were fleeing to higher ground, even some elephants breaking their chains to escape. While animals apparently sense the natural signs developed over thousands of years to help them survive, humans seem distracted by material things that keep them disconnected from the messages of nature.
“An education in ecological responsibility is urgent,” writes John Paul II, “responsibility for oneself, for others, and for the earth...a true education in responsibility entails a genuine conversion in ways of thought and behavior.”
Our economic system based on growth from burning fossil fuels is ruining our physical lives by destabilizing the climate and altering the sea level. We are burning not only the furniture, but the studs in the walls to fuel the furnace. For the good of future generations and the survival of many poor today, we must somehow change our life styles and public policies and reduce the carbon dioxide levels to below the threshold number of 350 ppm.

We are living in a World without consequence. There will be no one to remember us. If we wrote our story in stainless steel, by the time someone evolved to read it, it would be unrecognizable. The impetus for decency must now only come from within.
According to science life automatically generates under the right conditions. If life is an automatic feature of certain landscapes why is it not "out there"? Why do we get not answers to our queries, why are the heavens silent?
Life's evolutions across the universe is an inefficient process that leaves unused energy behind as a byproduct. By the time life evolves to the point where it can "send a signal", it has already figured out how to harness this energy for its own uses. It is like a teenager on a motorcycle with the sudden influx of free calories. Wheeeeeee ! By the time life figures it out, it is too late. We evolved to the point where we could send a signal 50 years ago. In twenty we will be gone and silent. The probability of life "out there" contacting us has to include the factor of a 100 year time frame. The heavens are silent because they, the ones capable of sending such a signal, are dead. And now we set upon the path to follow in the mode for the same reasons.
