I've got your good environmental news and your bad environmental news. Let's start with the bad:

An international team of 21 authors from 17 institutions in seven countries has just published a study in the journal Nature Climate Change showing that, as the cover of snow and ice in the northern latitudes has diminished in recent years, the temperature over the northern land mass has increased at different rates during the four seasons, causing a reduction in temperature and vegetation seasonality in this area. In other words, the temperature and vegetation at northern latitudes increasingly resembles those found several degrees of latitude farther south as recently as 30 years ago.

The south is climbing north at a startlingly rapid pace. But in happier news, those electric cars that conservatives have been hating on for ages are proving to be a good investment idea:

Tesla Motors Inc. (TSLA), which received $465 million in U.S. Energy Department loans to develop and build electric cars, will repay the funds five years ahead of schedule in a plan approved by the government.

Conservatives have been predicting the death of Tesla and deriding the Obama Administration's investment in Tesla for years now, so this is some welcome news for an industry that needs to succeed if we're going to keep palm trees where they're supposed to be.
