Adapt, Move or Die: How Biodiversity Reacted to Past Climate Change

American Pika; Public Domain

A new paper reviews current knowledge on climate change and biodiversity. In the past, plants and animals reacted to environmental changes by adapting, migrating or going extinct. These findings point to radical changes in biodiversity due to climate change in the future. The paper is published in the scientific journal Trends in Ecology and Evolution by an international group of scientists led by the Center for Macroecology, Evolution and Climate, University of Copenhagen.

Nature is reacting to climate change. We see altered behaviour and movement among plants and animals; flowers change flowering period and owls get darker body colour, due to warmer winters. So, how does the future for biodiversity look like? Will plants and animals be able to adjust quickly enough to survive the changing temperatures, precipitation and seasons?

Prehistoric Changes in Vegetation Help Predict Future of Earth's Ecosystems

As the last ice age came to an end and the planet warmed, the Earth's vegetation changed dramatically, reports a University of Arizona-led international research team.

The current warming from climate change may drive an equally dramatic change in vegetation within the next 100 to 150 years unless greenhouse-gas emissions are reduced, the team wrote.

"We found that ecosystems all over the globe experienced big changes," said Connor Nolan, a doctoral candidate in the UA Department of Geosciences. "About 70 percent of those sites experienced large changes in the species that were there and what the vegetation looked like."

USDA Forest Service Announces New Strategy for Improving Forest Conditions

Washington, D.C., August 16, 2018  — The U.S. Department of Agriculture (USDA) Forest Service (USFS) announced today a new strategy for managing catastrophic wildfires and the impacts of invasive species, drought, and insect and disease epidemics.

Specifically, a new report titled Toward Shared Stewardship across Landscapes: An Outcome-based investment Strategy (PDF, 3.7 MB) outlines the USFS’s plans to work more closely with states to identify landscape-scale priorities for targeted treatments in areas with the highest payoffs.

Wildfires and Washington: How Congress Can Stop Catastrophe Before It Starts

Opinion: Chairman Rob Bishop (R-Utah)

Charred landscapes, torched buildings and the loss of property and life. These are the consequences of massive wildfires. Most Americans in the Eastern United States aren’t acquainted with this type of destruction. However, these scenes are all too familiar for those of us who live in the West.  

Congress and the U.S. Forest Service have the opportunity now to stop catastrophic wildfires before they start. This is not some pie-in-the-sky hyperbole coming from Washington. It’s a realistic goal, achievable by using proven science to manage our country’s forests.
