New study warns we’re not moving fast enough to avoid the worst effects of climate change

A new credible study warns of an impending climate disaster, you should take notice. The study argues that the serious effects of climate change — sea level rise of several feet, followed by increases so large they would force humanity to flee the coasts — will occur over the next 50 years, not over the course of centuries as climate scientists currently believe.

Lead author in the study is Dr. James Hansen, retired NASA scientist and director of the Columbia University Climate Center. The paper, published in the European journal Atmospheric Chemistry and Physics, was co-authored with 18 other scientists. Dr. Hansen has been right before. He gained fame in 1988 when he warned Congress that global warming had already begun. He was ahead of the scientific consensus at the time, but he was right.

This is big news. Dr. Hansen’s study will dominate scientific debate on climate change for years to come. To read more, and watch Dr. Hansen’s 15 minute video overview of the study, click the link. Continue reading

Study: Native trout populations endangered by global warming

We’re about a month away from the first mayfly hatch, and it’s getting to be time for a fisherman’s thoughts to turn to casting a fly on one of the magnificent wild trout streams along the Beartooth Front.

It’s something we take for granted, but a recent study by a team of researchers from the US Geological Survey (USGS), including two based in Montana, found that changes in climate directly and consistently influence trout populations worldwide.

“The key message is that climate does have a strong influence on trout populations, and this is something we have observed over time,” said lead author Ryan Kovach, stationed at Glacier National Park. “We’ve seen that year-to-year variations in streamflow and temperature can have an impact on trout populations. This highlights that climate and climate change is not speculative, it is realized. It is something that we need to confront now in terms of natural resource management, but also from a societal perspective.”

As waters inevitably warm and river levels drop, it is critical that we do everything we can to minimize impacts on our native trout populations. Continue reading
