NASA on Human Caused Climate Change

As Richard Land and the modern day flat-earthers in the SBC and the Christian Right are disputing the role that humans are playing to cause climate change, NASA is publishing a study that demonstrates the linkage. Here's a quote from a NASA press release:

The team conducted a "joint attribution" study. They showed that at the global scale, about 90 percent of observed changes in diverse physical and biological systems are consistent with warming. Other driving forces, such as land use change from forest to agriculture, were ruled out as having significant influence on the observed impacts.

Next, the scientists conducted statistical tests and found the spatial patterns of observed impacts closely match temperature trends across the globe, to a degree beyond what can be attributed to natural variability. The team concluded observed global-scale impacts are very likely because of human-caused warming.
