How to save the Earth from an asteroid strike.
Large asteroid hits on Earth have the potential to wipe out humanity so knowing how to detect and deflect them is vital. But we know very little about the interior make up of many asteroids.
Human activity doesn't just reduce biodiversity – new research explores how we are continually creating new species and ecosystems, too.
New study supports the idea that an asteroid, rather than climate changes, caused the mass extinction that wiped out the dinosaurs.
Coral bleaching in March 2016. Rapid rises of greenhouse gases in the past have been linked to major extinctions in the oceans.

Carbon dioxide is rising faster than any time in the past 66 million years. Rapid rises in the past have been linked to mass extinctions.

Why we won't see a Planet of the Apes when humans are gone.
A cosmological event could have unleased the huge comet or asteroid that led to the demise of the dinosaurs.
Many marine reptiles like this nothosaur went extinct at the end of the Triassic, one of five major mass extinction events on Earth.
A fall in vital trace elements in our oceans could be one of the driving forces behind a number of mass extinction events during Earth's history.
When the asteroid struck the dinosaurs departed, leaving the planter
Mass extinctions are more complicated than ‘strength in numbers’.
Being big – larger than a dog – increases the risk of being wiped out in a mass extinction.
Bye bye humanity…. now what?
With most species out of the way, remaining plants and animals rush to evolve into the ecological gaps.
A Steller sea cow skeleton: extinct in 1768.
Analysis of extinction rates over the past centuries shows that humans are causing the sixth mass extinction in the history of the Earth.
How long before the rhino joins the list?
Even if humans survive the planet will never be the same again.
Costa Rica’s golden toad is now gone forever.

Humans have wiped out 13% of the world's plants and animals species, according to a new study.
Our solar system is far from empty. A rogue asteroid or comet may have been responsible for the largest impact site yet discovered in Warburton in central Australia.

The largest meteorite impact site in the world may be right here in central Australia.
Are you afraid of the dark matter?
European Southern Observatory
Every 30 mil years, Earth has to deal with more comet crashes from space and more intense geological activity from within. Dark matter may be the culprit in these episodes that can cause mass extinction.
Carbon dioxide levels are rising at their fastest rate since the dinosaurs’ time.
The latest climate projections released last week by the Bureau of Meteorology and CSIRO predict that Australia could potentially warm by between 2.8C and 5.1C by 2090. Meanwhile, the 2014 State of the…
Zoos provide succor for species having a tough time of it in the wild.

Today, many zoos promote the protection of biodiversity as a significant part of their mission. As conservation “arks” for endangered species and, increasingly, as leaders in field conservation projects…
A dead coral reef in the Caribbean. Coral reefs are extremely vulnerable to climate change and ocean acidification.
Scientists are coming to the conclusion that we are on the brink of a mass extinction — the sixth known in the history of the Earth, and the latest since an asteroid killed off the dinosaurs 65 million…
The Great Dying broke even the trilobite’s back.
The worst time to be alive in Earth’s history is unarguably the end-Permian, about 250 million years ago. It is the period…
For millennia, humans have had the tools to change the atmosphere: when will we develop a sense of caution?
The era in which humans have had the power to alter the conditions for all life on Earth is widely thought to have begun with the Industrial Revolution 250 years ago. This era has been dubbed the “Anthropocene…
