"On September 27 2013 the 5th Assessment Report by the Intergovernmental Panel on Climate Change (IPCC) will be released. One part of this report will address the so-called "warming hiatus". This is the argument that warming has stopped, with the further assertion in some quarters that we therefore have nothing to worry about in the future."

"The latest forecasts from a foremost climate research institute that global warming has slowed present a new challenge to policymakers on how to inject urgency into the campaign to cut emissions of greenhouse gases. Climate change is a growing problem. Each year in the past decade has been hotter than the 1981-2010 average, and extreme heat waves are becoming more frequent. But the research indicates the rate of warming has slowed in the past decade and a half due to temporary natural factors."

BONN, Germany, May 24 (Reuters) - Greenhouse gas emissions in 2020 could rise to nine billion tonnes above what is needed to limit global warming as some countries look set to miss their emissions cut targets, a report by three climate research groups said on Wednesday.

"Ask a Wall Street analyst and all but the most extreme contrarians will tell you that over the long run, the market is going to go up. Sure, over the last century there have been some downturns, and some flat periods of little growth, but if you invested over the long haul you were virtually guaranteed to make money. Now consider the question: Is the planet warming?"

"A common refrain by climate sceptics that surface temperatures have not warmed over the past 17 years, implying climate models predicting otherwise are unreliable, has been refuted by new research led by James Risbey, a senior CSIRO researcher. Setting aside the fact the equal hottest years on record - 2005 and 2010 - fall well within the past 17 years, Dr Risbey and fellow researchers examined claims - including by some members of the Intergovernmental Panel on Climate Change - that models overestimated global warming. In a study published in Nature Climate Change on Monday, the team found that models actually generate good estimates of recent and past trends provided they also took into account natural variability, particularly the key El Nino-La Nina phases in the Pacific."

"A new report from the World Bank, 'Turn Down the Heat' warns that already global warming of around 1.5°C above pre-industrial times is locked into the Earth's atmospheric system. Unless we act now to reduce emissions, warming of probably 4 degrees will occur within our century, and everyone will feel the impact, particularly the poor."

"A report by a team of international scientists concludes there now is no doubt climatic changes are due to humans rather than any other natural factors."

"You've likely seen the graph of the Earth's average global temperature over the past 2000 years...it's mostly a straight line until you get to the industrial revolution and then it shoots up. It looks like a hockey stick. In a study published today in Science, that graph has been extended back 11,300 years and you can really see the scope of the abrupt temperature change."

"United Nations Secretary-General Ban Ki-moon has said that the battle for global sustainability will be won or lost in the world's cities. Cities and urban areas are estimated to account for 80 per cent of global greenhouse gas emissions, and more than half of the world's population live in them, so what we do in our urban centres will, to a large extent, define the future of our world. Governments are struggling to agree on action against climate change, but thankfully many city authorities are just getting on with tackling the problem as best they can. Element takes a look at what authorities in Auckland, Wellington and Christchurch are expecting, how they are trying to minimise the damage and preparing for the worst, and how their plans shape up against those elsewhere."

"Global warming's maths means Australia really counts It's simple maths: we can burn less than 565 more gigatons of carbon dioxide and stay below 2°C of warming - anything more than that risks catastrophe for life on earth. The only problem? Fossil fuel corporations now have 2,795 gigatons in their reserves, five times the safe amount. And they're planning to burn it all - unless we rise up to stop them."

Last week the world's atmosphere took a giant leap backward. For the first time in more than 3 million years, the atmospheric concentration of carbon dioxide (CO2) reached 400 parts per million. This was recorded at the National Oceanic & Atmospheric Administration's Earth System Research Laboratory located on Mauna Loa in Hawaii right out in the middle of the Pacific Ocean, a long way from major sources of CO2 in Asia and North America. What this means for the environment is uncertain but it's likely that, if no measures are taken to reduce this level of greenhouse gas, we could be headed for 3-4 degrees C warming globally by the end of this century

"Some of the most extreme predictions of global warming are unlikely to materialise, new scientific research has suggested, but the world is still likely to be in for a temperature rise of double that regarded as safe."

"Last night's ABC Q&A program didn't spend much time discussing the issue of climate change, but it nonetheless represented an excellent microcosm of the broader political debate on the issue. On one side you had Bill McKibben, who has dedicated his life to the cause of reducing greenhouse gas emissions. He is trying to put the fear of God into investors that money in fossil fuels is like investing in the horse and buggy industry at the dawn of the motor vehicle. In the other corner was Cory Bernardi, one of the ring leaders behind the toppling of Malcolm Turnbull because of his support for an emissions trading scheme, who believes global warming is a fraud."

"Buried in a little-noticed rule on microwave ovens is a change in the U.S. government's accounting for carbon emissions that could have wide-ranging implications for everything from power plants to the Keystone XL pipeline. The increase of the so-called social cost of carbon, to $US38 ($A40) a metric ton in 2015 from $US23.80, adjusts the calculation the government uses to weigh costs and benefits of proposed regulations. The figure is meant to approximate losses from global warming such as flood damage and diminished crops. (That figure also compares with the $A23 per tonne carbon tax in Australia.)"

"There are three numbers you need to really understand global warming: 275, 400, and 350."

The effects of global warming will persist for hundreds of years. What are our responsibilities and duties today to help safeguard the distant future? That is the question ethicists are now asking.

The world experienced unprecedented high-impact climate extremes during the 2001-2010 decade, which was the warmest since the start of modern measurements in 1850 and continued an extended period of pronounced global warming. More national temperature records were reported broken than in any previous decade, according to a new report by the World Meteorological Organization (WMO).

"The Clean Energy Bill 2011 is a package of legislation that establishes an Australian emissions trading scheme designed to reduce carbon dioxide emissions and limit global warming"

"The greening of American energy is both real and profound. But there's a flip side to this American success story. Even as our nation is pivoting toward a more sustainable energy future, America's oil and coal corporations are racing to position the country as the planet's dirty-energy dealer - supplying the developing world with cut-rate, high-polluting, climate-damaging fuels. Much like tobacco companies did in the 1990s - when new taxes, regulations and rising consumer awareness undercut domestic demand - Big Carbon is turning to lucrative new markets in booming Asian economies where regulations are looser. Worse, the White House has quietly championed this dirty-energy trade."
