Scientists have obtained more precise dates for the Deccan Traps volcanic lava flows, linking peak activity more closely to the asteroid or comet impact 66 million years ago and the coincident mass extinction. But if greenhouse gases emitted before the impact created a hothouse climate that set life up for a fall when the impact cooled the planet, those gases did not coincide with the largest lava flows from the Deccan Traps.
In fact, as long as we don’t claim a theory of evolution we get it ‘about right’: we ‘see’ (??!) evolution in deep time as a progression of forms. But the moment we sa…
We are told that little is known about co-evolution and symbiosis, which prompts a question: How does the requirement for synchronization affect the overall complexity of the system?
The Fernandina Giant Tortoise was thought to have been hunted into extinction.
Global emissions are on the rise as national commitments to combat climate change come up short. But surging momentum from the private sector and untapped potential from innovation and green-financing offer pathways to bridge the emissions gap. Those findings along with a sweeping review of climate action and the latest measurements of global emissions were presented by authors of the 2018 Emissions Gap Report.
