Climate Change Could Render Many Ecosystems Unrecognizable

In Bordeaux, Rising Temperatures Bring a Reckoning for Winemakers

Bordeaux's climate is steadily getting hotter, and that has French winemakers on edge.

Colorado Voters Will Get to Decide Whether to Tighten Oil Drilling Rules

A Colorado ballot initiative that would sharply increase the required distance between new oil wells and populated areas will go to voters in November, state officials announced.

At Water-Starved Lakes Mead and Powell, 'Crisis Is Already Real'

Lake Mead's water levels have dropped so much they could trigger water use cutbacks within two years, and a new report says the situation is just as worrisome upstream at Lake Powell. The Colorado River basin, which provides water for about 40 million people, has long been over-allocated, and the strain is compounded by drought and climate change.

Warmer Water Under Arctic Ice a 'Ticking Time Bomb,' Researcher Says

A pocket of warmer ocean water underneath the surface of the Canada Basin could melt a significant portion of the region's sea ice pack if it were to ascend, a new study suggests. Scientists believe the warmer water is coming from the edges of the basin, places like the Northern Chukchi Sea.

Canada’s Strong Words on Climate Face a Test in Trump’s NAFTA Rewrite

Canada has staked out a position that any changes to NAFTA must recognize climate change, a stance that is now facing a test as the Trump administration says it and Mexico are finalizing a revision.

‘Climate Gentrification’ Is Changing Miami Real Estate Values

Home values on Miami's coast are already worth 10 percent less than if climate change wasn't a factor, according to the co-author of a Harvard study that looks at the role of global warming in real estate markets. The study looked at the values of single-family homes across Miami going back 45 years and found that properties at higher elevations are increasingly worth more.
