Peter Hannam 9:07 AM Global temperatures continued to climb last month, with combined land and sea-surface temperatures setting fresh records amid prospects of more to come as El Nino conditions form in the Pacific, the US National Oceanic and Atmospheric Administration said.
Peter Hannam AGL, the country's largest greenhouse gas emitter, has vowed to close all its existing coal-fired power stations by 2050 and will not build or buy new conventional plants in the meantime.
Chris Mooney We often hear that climate change is radically reshaping the Arctic, a place many of us have never visited. As a result, it can be pretty hard to feel directly affected by what's happening up in a distant land of polar bears, ice floes and something odd called permafrost.
Tom Bowker Over the last seven years the Mozambican village of Guguruni has housed hundreds of people whose homes elsewhere were destroyed by floods. This year it succumbed.
Clare Colley Canberra is a world-leader when it comes to climate change policy, but Australia is still not doing enough to tackle the problem, former chief scientist Professor Penny Sackett says.
Peter Hannam Global temperature records continue to tumble with March coming in as the hottest in data going back to 1891, according to the Japan Meteorological Agency
Matthew Knott The man appearing on television screens across the country promoting the Abbott government's Intergenerational Report - Karl Kruszelnicki - has describing the document as "flawed" and admitting to concerns that it was "fiddled with" by the government.
Peter Hannam Australia’s large-scale renewable energy industry has entered an investment freeze with just one project securing finance in the past six months amid political uncertainty, according to Bloomberg New Energy Finance.
Peter Hannam Sea temperatures around Australia are posting "amazing" records that climate specialists say signal global records set in 2014 may be broken this year and next.
Peter Hannam Australia's chances of a hotter and drier than usual year have increased with the likelihood of an El Nino event forming in the Pacific Ocean this year now an odds-on risk, the Bureau of Meteorology said.
China is poised to overtake the United States as the main cause of man-made global warming since 1990, the benchmark year for U.N.-led action, in a historic shift that may raise pressure on Beijing to act.
Michael McDonald As US universities face growing student pressure to divest fossil-fuel holdings from their more than $US500 billion ($658 billion) in endowments, Cambridge, Massachusetts, finds itself at the centre of a great divide.
Clancy Yeates Nine months after the carbon price was repealed, the good times are back for some of the most carbon-intensive electricity generators in the developed world.
Meager precipitation and a premature spring thaw caused by unusually mild temperatures last month have left the US Western mountain snowpack, a key source of fresh surface water for the region, at record low levels, the government has reported.
Was it an accident or wilful blindness? The federal government's 74-page energy white paper, released last week, contained just a single reference to climate change. Given the Abbott government's self-imposed blindness on this issue, we have to suspect it was the latter. The omission renders the document deeply flawed.
Lucy Cormack Nic Nelson was wandering through a market one morning when he was made an offer to shift his life savings to a fossil fuel free super fund.
A US government weather forecaster on Thursday raised its forecast for the chance of El Nino conditions during the Northern Hemisphere summer to 70 per cent, up from a 60 per cent chance last month, with a 60 per cent chance it lasts through autumn.
It is one of science's enduring mysteries: what caused the worst mass extinction in Earth's history. And, no, it is not the one that wiped out the dinosaurs.
Chris Mooney As the frozen Arctic soil known as "permafrost" thaws, it could release large amounts of carbon - in the form of both carbon dioxide and methane - to the atmosphere. And this new source of greenhouse gas emissions could be large enough that it could substantially undermine attempts to cut down on emissions from fossil fuels.
Justin Sink President Barack Obama is warning that climate change will start affecting the health of Americans in the near future and he's recruiting top technology companies to help prepare the nation's health systems.
John Schwartz The glaciers of the Canadian West could shrink by 70 per cent by 2100, according to new research that has implications for predicting glacier loss around the world.
unknown California has taken the most drastic measure yet to combat the worst drought in the state's history.
Markus Mannheim The controversial Dane has struck a four-year deal to run a policy research centre in Perth.
Samantha Masunaga Global investment in renewable power and fuels reached $US270.2 billion ($355 billion) last year, nearly 17 per cent higher than in 2013, according to a new study on renewable energy investment from the United Nations Environment Programme.
Geoffrey Mohan Naturally occurring climate change lowered oxygen levels in the deep ocean, decimating a broad spectrum of seafloor life that took some 1,000 years to recover, according to a study that offers a potential window into the effects of modern warming.
Lisa Cox and Peter Hannam The UN wants nations to release their longer-term targets well in advance of the Paris summit late this year that will aim to thrash out a new worldwide climate treaty.
Alex Nussbaum Facing Republican resistance at home and delays abroad, the Obama administration Tuesday pledged its most ambitious target yet for cutting global warming pollution.
