The March-April issue of the TCCPI Newsletter highlights the wide ranging work of the Tompkins County government and other members of the TCCPI coalition to reduce greenhouse gas emissions, improve energy efficiency, and accelerate the transition to a clean energy economy. Clearly, it’s an impressive record, one that demonstrates the commitment of our community to meet the central challenge of our time.
Elsewhere in the United States and around the world similar work is going on in thousands of communities. The crucial question, of course, is will it be enough to stave off runaway climate change? Can we make the changes necessary at the required scale and rate to avoid the 2 degrees Celsius increase scientists say will set off climate catastrophe
The latest assessment of the Intergovernmental Panel on Climate Change (IPCC), the United Nations group that issues periodic summaries of the ongoing research on climate science, underscores the speed at which we are hurtling toward the point of no return. As the Guardian observes, the new study emphasizes five key points:
- Climate change is already posing a serious threat to the world’s food supply and will only get worse, especially in light of projected population growth.
- Potential shortages of food and water will become major drivers of future conflicts, undermining human security in every hemisphere.
- Climate change is going to intensify existing inequalities and have a disproportionate impact on poor people in both developed and developing nations.
- Our current trajectory puts us on course to raise the average global temperature 4 degrees Celsius, ensuring that no one will escape the effects of climate change.
- We face a difficult but not hopeless task and can still prevent the worst effects off climate change from occurring.
It’s a sobering picture: the passenger jet on which we are traveling is in a steep dive, we don’t quite know when the craft will begin to come apart because of the stress on its systems and structural integrity, and if we don’t pull out of the dive soon, it will surely crash.
Fortunately, in a follow up report released on Sunday the IPCC finds that the cost of implementing the transformation necessary to avoid the crash would shave only 0.06% off expected annual global economic growth rates of 1.3%-3%. The IPCC analysis does not take into account the environmental and health benefits of cutting greenhouse gas emissions, which could very well offset the costs of a sweeping shift to clean energy.
Here’s the rub, though: the longer we wait the more it will cost. In short, the time for a massive mobilization is now.
