This article from the Smithosian Institute is informative about the need.
2013 was a great year for science. We discovered hundreds of exoplanets, found yet more evidence of ancient water on Mars and learned all about our species’ own evolution.
But it’s important to remember that, in terms of the long-term survival of both our species and all others on the planet, 2013 is remarkable for a much darker reason. It’s a year in which we’ve pushed the climate further than ever away from its natural state, learned more than ever about the dire the consequences of doing so, and done as little as ever to stop it.
As greenhouse gas emissions soar unabated and the ramifications become rapidly apparent, here’s a rundown of what we learned about climate change in 2013:
All six things can be read at:
Here are the last two:
5. There’s not nearly enough being done to stop climate change. There have been some bright spots in 2013: Production of renewable energy in the U.S. has continued to increase, now accounting for a little over 14 percent of the country’s net energy generation. Due to this trend—and the continued decline of coal, replaced in part by less carbon-dense natural gas—U.S. carbon dioxide emissions are at the lowest levelsthey’ve been in twenty years.
But this apparent good news simply hides another troubling trend: Instead of burning our coal, we’re simply exporting more and more of it abroad, especially to China. And unfortunately, there are no borders in the atmosphere. The climate’s going to change no matter where fossil fuels are burned.
This further emphasizes the need for an international agreement to regulate greenhouse gas emissions, something negotiators have repeatedly tried and failed to reach before. Climate activists are hopeful that the 2015 round of UN negotiations, to be held in France, will result in a meaningful agreement, but there are a lot of hurdles to be cleared before that can happen.
6. There is one key formula to preventing catastrophic climate change. The amount of data and fine detail involved in calculating climate change projections can seem overwhelming, but a report released this summer by the International Energy Authority articulates the basic math.
Of all existing fossil fuel reserves that are still in the Earth—all of the coal, oil and natural gas—we must ultimately leave two-thirds unburned, in the ground, to avoid warming the climate more than 2° Celsius (3.6° Fahrenheit), a number scientists recognize as a target for avoiding catastrophic climate change.
If we can figure out a way to stay within this carbon budget before it’s too late, we can still avert a climate disaster. If we can’t, then we too might look back at today’s record-breaking temperatures, droughts and floods as a fond memory of milder times.
