Harvard and Rutgers scientists propose a new, potentially more accurate way, to measure the rate of sea level rise. Shutterstock

Solving the puzzle of sea-level rise by reexamining the past

When you ask yourself what the biggest unanswered scientific questions are, “how did sea levels change over the past 100 years?” is unlikely to appear at the top of your list. After all, haven’t we already…

Obituaries for coral reefs may be premature, study finds

Coral reefs are the poster child for the damage people are doing to the world’s oceans. Overfishing, pollution and declining water quality have all taken their toll on reefs around the world. Perhaps the…

Early birds: how climate change is shifting time for animals and plants

Every Spring, the blanket of Australian alpine snow starts to melt, and the Mountain Pygmy Possum wakes up from its seven-month-long hibernation. Naturally after so long under the snow, its first thought…

Australia faces a stormier future thanks to climate change

The supercell that hit Brisbane on November 27 this year caused more than A$500 million worth of damage, produced hail up to 7.5 cm in diameter, and lashed the city with winds of more than 140 km an hour…

Sudden global warming 55m years ago was much like today

It is often said that humans have caused the Earth to warm at an unprecedented rate. However researchers have discovered another period, some 55m years ago, when massive volcanic eruptions pumped so much…

It’s time for environmentalists to give nuclear a fair go

Should nuclear energy be part of Australia’s (and many other countries’) future energy mix? We think so, particularly as part of a solution to reduce greenhouse gas emissions and prevent dangerous climate…

Cities could be the secret to fighting climate change

The world’s population could reach almost 10 billion by 2050. Most people will live in cities. To accommodate an additional 3 billion people, we’ll need to build the equivalent of one new city, that can…

Meet N2O, the greenhouse gas 300 times worse than CO2

When we talk about greenhouse gases we usually talk about carbon dioxide. When media reports depict climate change, we invariably see the cooling towers of a coal power station. Which is fair, because…

Cap and trade could be the answer to state budget crises

So-called cap and trade may be a solution to a problem it was not intended to solve: state budget crises. Cap-and-trade policy was designed to address climate change by putting a “cap” on carbon dioxide…
