Why is the eastern monarch butterfly disappearing?
A Spartan-led research team has uncovered an answer at least for the most recent population decline with a huge assist from volunteers
Michigan State University ecologists led an international research partnership of professional and volunteer scientists to reveal new insights into what’s driving the already-dwindling population of eastern monarch butterflies even lower.
Between 2004 and 2018, changing climate at the monarch’s spring and summer breeding grounds has had the most significant impact on this declining population. In fact, the effects of climate change have been nearly seven times more significant than other contributors, such as habitat loss. The team published its report July 19 in the journal Nature Ecology & Evolution.

Researchers are bringing science to bear on the question and consequences of humans using technology to put the brakes on global warming.
Nine of the hottest years in human history have occurred in the past decade. Without a major shift in this climate trajectory, the future of life on Earth is in question, but is geoengineering a cooler Earth the way to go?
“There is a dearth of knowledge about the effects of climate intervention on ecology,” says Phoebe Zarnetske, associate professor in the integrative biology department in Michigan State University’s College of Natural Science and lead author of the new paper in the
Researchers Explore the Effect of Solar Climate Interventions on Ecology

Scientists in the Climate Intervention Biology Working Group, which includes Jessica Hellmann from the University of Minnesota (U of M) Institute on the Environment, examined the impact of solar climate interventions on ecology.

The study was published in the
Proceedings of the National Academy of Sciences.
The research group, which included ecologists and climate scientists from top-class research universities on a global scale, discovered that more studies are required to comprehend the ecological effects of solar radiation modification (SRM) technologies that reflect small amounts of sunlight again into space.
