Global acceleration in rates of vegetation change
Wherever ecologists look, from tropical forests to tundra, ecosystems are being transformed by human land use and climate change. A hallmark of human impacts is that the rates of change in ecosystems are accelerating worldwide. Surprisingly, a new study, published…
Earth’s vegetation is changing faster today than it has over the last 18,000 years
MADISON – A global survey of fossil pollen has discovered that the planet’s vegetation is changing at least as quickly today as it did when the last ice sheets retreated around 10,000 years ago. Beginning some 3,000-to-4,000 years ago, Earth’s…
A tale of frozen landscapes is also an urgent call to action
The catastrophe Wadham is seeing unfold is the rapid melting and demise of our planet’s glaciers. A demise that will cause global humanitarian crises, if not halted: 70 per cent of fresh water on Earth is locked up in glaciers.…
The environmental trade-offs of autonomous vehicles
Optimistic predictions expect reliable autonomous vehicles to be commercially available by 2030, at a time when mobility is undergoing a profound shift away from traditional modes of transportation and towards door-to-door services. Previous analysis suggested that public transport will lose…
