Is it right to be worried about Murdoch's new part stake in National Geographic's media arm?

This year's El Nino weather pattern is shaping up to be one of the strongest, if not the strongest, on record - bringing with it an elevated risk of drought.

Today marks D-Day for divers around the country who will recover as much rubbish as they can from the ocean this month as part of the Dive Against Debris effort.

If we are going to continue down the TPP path then we need to have confidence that it is not taking us in the wrong direction, writes Peter Whitmore.

New Zealand's postcard glaciers will by 2100 bear little resemblance to how they appear today - and climate change will be to blame.

A growing El Nino looks set to bring dry "spring-like" conditions to NZ until early next year - but there is no way of knowing the extent of its impact this far out.

We are in awe of the discoveries in outer space but sceptical about climate change - and with good reason, argues John Roughan.

What have drones got to do with native plants? Quite a lot actually. And science reporter Jamie Morton will tell us why.

"New Zealand's climate target shows it's far from doing its fair share, and is anything but ambitious."

Is the emissions-reduction target the Government announced this week ambitious, as it says, or feeble and inadequate, as its critics say?

It is not for us to lead, says Tim Groser. Far from leading, however - apart from on emissions, where we're fifth per capita of developed countries - we're dragging our heels, writes Toby Manhire.

Never mind the CIA and the Pentagon, scientists and researchers - our Climate Change Minister knows better than anyone in the area of greenhouse gas emissions.

The Government will take a highly conditional pledge to cut New Zealand's greenhouse gas emissions by 2030 to 11 per cent below 1990 levels to the Paris climate conference in December.

The Government has set what is says is an achievable, fair target for cutting atmosphere-warming emissions, but critics say the new target is "100 per cent pure spin".

Economics editor Brian Fallow says the Government's climate change pledge will be hedged with conditions.

Kiwis are among the least likely in the developed world to believe in climate change, a study has revealed.

Earth has entered its sixth mass extinction with animals dying out at 100 times the normal rate, scientists have warned.

Pope Francis has blamed the rich and powerful for placing the planet in unprecedented danger as he demanded urgent and concerted global action against climate change.

Studies using Nasa satellites show the Earth is rapidly running out of fresh water.

Owner's of terrier swept out to sea near St Clair says she'd "never seen waves like this before" as climate experts warn that NZ coast at is at risk to extreme weather.

The Prime Minister says although climate change is an important issue, he does not believe every new law should take it into account.

Stand by for an unholy row as the Pope comes out as perhaps the world's most effective environmental campaigner.

New Zealand can expect more droughts as climate change hits home, a government minister said this morning.

Paris is the venue for the next attempt to cut carbon emissions. NZ will be there, but what will we be bringing to the fight?

A long-standing mystery over why the world’s sea level was dramatically higher 135,000 years ago than it is today is closer to being solved by scientists.
