Good news on Climate Change front [View all]

[LouisvilleDem]

Several peer reviewed papers say we probably have more time to act on climate change than was originally thought. All of the urgency to lower CO2 emissions stem from computer model projections that say the 2C target might be exceeded as soon as 2040 if economic and population growth continue as they have. However, observed temperature changes over the last 15-20 years now make that prediction seem extremely unlikely. Moreover, new evidence suggests that those climate models are using climate sensitivity figures that are twice the actual figure, meaning we have more time than we originally thought to avoid a 2 degree increase in global temperatures.
