Climate change: How damaging is methane?
By Zebedee Nicholls & Tim Baxter Methane is a shorter-lived greenhouse gas – why do we average it out over 100 years? By doing so, do we risk emitting so much in the upcoming decades that we reach climate tipping points? The climate conversation is often...
How can water help us adapt to survive as the climate changes? ▶
The natural sciences that allow us to understand the environment are at the heart of developing strategies to adapt to, survive, and thrive as climate changes. Water is at the heart of many of the most complex problems in climate sciences: understanding the behavior...
Are we doomed if we don’t manage to curb emissions by 2030?
By Robert McLachlan Humanity is not doomed, not now or even in a worst-case scenario in 2030. But avoiding doom — either the end or widespread collapse of civilisation — is setting a pretty low bar. We can aim much higher than that without shying away from reality....
What was the world like the last time carbon levels were this high?
By James Shulmeister What was the climate and sea level like at times in Earth’s history when carbon dioxide in the atmosphere was at 400ppm? The last time global carbon dioxide levels were consistently at or above 400 parts per million (ppm) was around four million...
Climate change: Should we be worried?
By Michael Grose & Julie Arblaster Just how hot will it get this century? Latest climate models suggest it could be worse than we thought. Climate scientists use mathematical models to project the Earth’s future under a warming world, but a group of the latest...
Why do volcanoes erupt and can we forecast future activity?
By Phil Shane One of the grand challenges of volcano science is understanding the behaviour of a volcano, and whether can we forecast the likelihood of future eruptions. Despite decades of high technology monitoring, and even longer historic records for some...
Q+A: Can we avoid the looming climate wars?
Our options as a humanity may be dwindling in the face of climate change. The coming changes may completely alter the world as we know it with collapsed ecosystems, mass immigration of climate refugees, and more devastating wars over basic necessities such as food and...
How do predators help farmers?
By Christopher O’Bryan, Eve McDonald-Madden, James Watson, Neil Carter Predators are helping farmers and reducing car crashes with surprising results. Humans may be Earth’s apex predator, but the fleeting shadow of a vulture or the glimpse of a big cat can cause...
How do we restore marine ecosystems? ▶
Professor Simon Thrush from the Institute of Marine Science at the University of Auckland talks about his big question, “how do we restore marine ecosystems?” Thrush’s current research interests focus on the ecology of coastal ecosystems, how they respond to...Subscribe by Email
