Renewable resources could meet most of U.S. electricity needs at costs comparable to today’s even as demand for electrical power increases. National greenhouse gas emissions could be slashed 78% by doing so, according to a new study from the Cooperative Institute for Research in Environmental Sciences (CIRES).
The U.S. DOT on December 7 announced it’s joining with Paul Allen’s Vulcan Inc. in launching a $40+ million Smart City Challenge centered on identifying and developing practical, cost-efficient means of addressing climate change by making innovative use of technology to improve urban transportation systems.
Increasing renewable energy to 36% of global energy production would take global society halfway towards the goal of limiting climate warming to the 2 degrees C tipping point, while energy efficiency improvements would take us the rest of the way there, according to IRENA.
New Arctic Ocean data adds to evidence linking rising CO2 levels to climate warming, which is occurring faster than it has since long before the Age of the Dinosaurs. A team of 40 researchers is gathering Arctic Ocean data before the region as we know it ceases to exist as the global average concentration of atmospheric CO2 surpassed 400 ppm.
In just three weeks, a raging inferno in Indonesia has released more CO2 than Germany does in a year, and more than that of the entire U.S. economy. Clearing forest and altering landscapes and waterways underlain by carbon-rich peat deposits for palm oil agriculture is to blame.
