2014 the warmest year as global heating speeds up

2014 was the hottest year in the global surface temperature record, according to independent analyses by NASA’s Goddard Institute for Space Studies (GISS), US National Climatic Data Center (NCDC), UK’s Met Office, and even the team of skeptics at Berkeley Earth. The one exception is the University of York dataset, which has greater warming over …

Global warming is already dangerous

“Over the bleached bones and jumbled residues of numerous civilizations are written the pathetic words: ‘Too late.’” – Martin Luther King Jr. I’ve been reading up on what the latest climate science says about where we are and where we’re heading, and decided the best way to present the information is in the following table. …

IPCC AR5: global warming more evident than ever

Last week, the Intergovernmental Panel on Climate Change (IPCC) released the first (and primary) instalment of its Fifth Assessment Report (AR5). Its key conclusions include: The Earth is accumulating heat. Heat-trapping greenhouse gases are rising: Atmospheric levels of carbon dioxide (CO2), methane, and nitrous oxide have reached levels unprecedented in at least 800,000 years because …

Caps Review Part 1: The global climate crisis

The Australian Government’s independent Climate Change Authority (CCA) is conducting a Caps and Targets Review this year. In this series I will explain why the review is important, outline what I think its recommendations should be, and attempt to deconstruct everything I believe is wrong with the Government’s climate policies and its underlying flawed beliefs …

Doha climate talks: Island states stand up for ambition

“We have not seen concrete progress on the issues that are important to ensuring the survival of all our members. How many conferences do we have to endure where we go back to our countries and say, ‘next year we will increase ambition to reduce emissions, next year we will see finance, next year we …

Arctic sea ice in a death spiral

Source: International Arctic Research Center As Australian politicians fiddle with the details of an extremely insufficient climate change policy, I’ve been watching Arctic sea ice news with increasing dismay. Summer sea ice in the Arctic is fast melting away, accelerated by amplifying feedbacks in what has been called a “death spiral”. The disappearance of Arctic …

Is Greenland close to a climate tipping point?

Recent findings suggest climate change in Greenland may be approaching a tipping point, beyond which amplifying feedbacks could lead (probably over centuries) to complete melting of the ice sheet, raising sea level by about 7 meters. In June, a team of glaciologists led by Jason Box predicted that we would see melting across 100% of …

Stop saying yes: “Political reality”

This is the fifth in a series of posts about the Australian climate movement. Global warming is not just another issue; it is an urgent threat to human civilization. To avoid passing tipping points for dangerous climate change, humanity must rapidly phase out fossil fuels to cut emissions to zero or near-zero as soon as …

Stop saying yes: Bright-siding

This is the fourth in a series of posts about the Australian climate movement. David Spratt at the blog Climate Code Red has recently spoken out against what he calls “bright-siding”: a misguided tendency for climate activists (and governments) to campaign on the arguable side-benefits of climate policies (eg. green jobs), rather than explain the …

Titanic and Global Warming

After the RMS Titanic’s collision with an iceberg a century ago today, the passengers did not believe the ocean liner would sink. The ship was so gargantuan and stably designed it showed few outward signs of being in imminent danger, and took 2 hours and 40 minutes to sink. But sink it did. The Earth’s …
