We can now see how humans have altered Earth’s water resources

For millennia, humans have harnessed rivers, built dams, and dug wells to quench our growing civilization. Now, for the first time, we have a picture of what all those generations have wrought on our blue planet’s most defining resource.

Newly analyzed data from groundwater-detecting satellites “reveals a clear human fingerprint on the global water cycle,” according to a study out Wednesday in the journal Nature. It’s the kind of … [more…]

Living in cities threatened by sea-level rise could be like living near an active volcano, according to NOAA oceanographer William Sweet. Some parts of the Earth are seeing sea levels rise far beyond average, and it’s just a waiting game before some areas are inundated with sea water, studies show.

The East Coast of the U.S. is experiencing "sunny day flooding" that scientists didn’t expect for decades yet. Sea levels

Climate change impact on communally managed water systems

ALBUQUERQUE, N.M. — Shared fates and experiences in a community can help it withstand changes to water availability due to climate change, a recent study by Sandia National Laboratories researchers found.

“During our research, a community’s ability to withstand natural and social pressures was routinely pinpointed to the fact that the people who live there feel like they are a community,” Thushara Gunda, a Sandia environmental engineer and the paper’s

The UN’s annual World Water Development Report 2018 has highlighted the need to use nature to combat the challenges of a growing population and climate change. In its detailed analysis, the report demonstrates that demand for water is increasing in developing countries, while simultaneously access is being put at risk by human development and climate change.

Deforestation, intense farming methods and urbanisation are putting these resources … [more…]

Louisiana, Sinking Fast, Prepares to Empty Its Coastal Plain

Louisiana, Sinking Fast, Prepares to Empty Out Its Coastal Plain
  • State weighs buyouts, prohibiting new development, tax hikes
  • Policy could become template for climate adaptation nationwide

Louisiana is finalizing a plan to move thousands of people from areas threatened by the rising Gulf of Mexico, effectively declaring uninhabitable a coastal area larger than Delaware. A draft of the plan, the most aggressive response to climate-linked flooding in the U.S., calls for prohibitions on building new homes in high-risk areas, buyouts
