Climate Change Grips Trout Streams Across the Nation: How Anglers Are Responding


A slow emergency is brewing in the peaceful waters of the Au Sable River. ⁠ ⁠

Michigan’s unusually warm winter temperatures, followed by a historic drought and one of the hottest summers on record are warming the river. When the water is warm, much of the trout population flees to the river’s tributaries, instinctively searching for oxygen-richer waters. ⁠ ⁠

It’s a story that’s playing out nationwide. The carcasses of spawning salmon, weakened by warm waters and low oxygen levels, are piling up and rotting in the Klamath River in California. Drought reduced once-raging Montana trout streams to a trickle this summer. Steelhead in the Columbia River are at an all-time low.⁠

As anglers survey the damage, they are taking up the call to protect the environment from more harm.

2021 Election Recap: New York Voters Approve Clean Water Constitutional Amendment


A movement to enshrine individual rights to clean air and water in state constitutions received a boost yesterday.⁠

By a large majority, New York voters approved the addition of an environmental rights amendment to their state constitution.⁠

Nearly 61 percent of voters endorsed the inclusion of new language in the state Bill of Rights. That foundational document will now protect the right to “clean air and water, and a healthful environment.”⁠

High-profile water-related issues were also on the ballot in Maine, Boise, and Virginia Beach.⁠

HotSpots H2O: The Philippines’ Largest Wetland Faces Prospect of Drilling

The vast oil and gas reserves that lie beneath the surface of the Liguasan marsh has remained untapped. But that might soon change. ⁠ ⁠

The marsh, located on the southern Philippine island of Mindanao, is a flourishing ecosystem. War has racked the island since the 1970s, amid the decades-long conflict between the Philippine government and the separatist Moro Islamic Liberation Front. Now, having gained its status as an autonomous region, the fledgling Bangsamoro government has invited investors to drill under the marsh for fossil fuels. ⁠ ⁠

The situation crystallizes several conundrums of global development: the plight of Indigenous communities, the often conflicting imperatives of economic stability and ecosystem preservation, and the temptation that planet-warming fossil fuels present for impoverished areas.⁠

What’s Up With Water – November 1, 2021

For the news you need to start the week, tune into “What’s Up With Water” fresh on Monday’s on iTunesSpotifyiHeart Radio, and SoundCloud.

  • In international news, this week marks the start of a critical UN climate conference, known as COP26. Leaders meeting in Glasgow, Scotland, have three main issues on the agenda.
  • In the Nile River basin last week, a political power shift in Sudan could turn up the heat on a long-simmering dispute over a major dam in the region.
  • In the United States, it’s election week, and Circle of Blue reports on state and local ballot measures related to water.

Scientists Concerned About the Bottom of the Food Web in the Great Lakes


Earlier this year, scientists aboard the R.V. Lake Guardian were taking samples and measurements of the Great Lakes. 

One trend they observed, the warming climate, could mean changes for the base of the food web in the lakes. But the researchers are not yet sure what those changes might be. 

One thing scientists are finding is changes in diatom populations. Diatoms are microscopic algae. Tiny organisms called zooplankton and some just-hatched fish like to eat diatoms. Those little fish either grow up or they’re eaten by bigger fish, the kinds people like to eat.

Algae such as diatoms are sensitive to water quality changes. The Great Lakes National Program Offices says diatoms can serve as the first indicators of nutrient and contaminant changes such as phosphorous runoff from farm fields and lawns. Some researchers believe that climate change may lower the productivity diatoms and other organisms lower in the food web. 

This piece was originally published by Michigan Radio as part of the Great Lakes News Collaborative. In the "Ready or Not" series, members of the Great Lakes News Collaborative explore what it may take to prepare the Great Lakes region for the future climatologists say we can expect.
