Continued “business as usual” reliance on fossil fuels is expected to lead to a doubling of pre-industrial CO2 levels by about 2050, and possibly a tripling by about 2100, explains the Academy of Science.
Climate science
Academy of Science: are human activities causing climate change?
The increase in greenhouse gas concentration happened about the same time as industrialisation, when the global human population began growing rapidly and farming also increased.
Academy of Science: how has climate changed during the recent past?
Measurements from many hundreds of thermometers around the globe, on land and over the ocean, show that the average near-surface air temperature increased over the 100 years to 2009 by more than 0.7°C.
Academy of Science: how has our climate changed in the distant past?
During the past million years, the average temperature of the Earth’s surface has risen and fallen by about 5°C, through 10 major ice age cycles. An extract from the Australian Academy of Science shows a varied climate throughout history.
The long view: re-assessing the IPCC science
In a recent speech, Professor Ross Garnaut warned that the latest scientific trends suggested increases in temperatures and sea-level rises were worse than predicted by the IPCC in 2007. Dr Andrew Glikson explains why.
Crikey Says: The climate’s changing
The climate’s changing rapidly. And we’re not talking about cO2 levels.
climate change The Australian Academy of Science: what is climate change?
The period for estimating climate is usually 30 years or more, long enough to sample a full range of weather.
The Australian Academy of Science: explaining climate change
The Australian Academy of Science is strongly committed to enhancing public understanding of scientific issues and how these may impact on society and the planet. This includes climate science, writes Prof. Kurt Lambeck.
Crikey Says: Climate change: the long view
Today, Crikey kicks off a new series we like to call Climate Change: The Long View.
A medieval climate
A new kind of science is being invented, free of data and unrelated to the basic laws of physics and chemistry. It’s a worrying development for human society when we ignore the climate science evidence, writes Dr Andrew Glikson.
Ask a climate scientist Rain, rain, go away
What areas of the plan will receive more rainfall as climate change continues and will this offset the desertification in other areas? Do water vapor emissions need to be reduced? Amber Jamieson asks the climate scientists.
Ask a climate scientist Does a sceptic’s claims hold up?
Crikey takes one climate sceptic — who, to be fair, is an ex-NASA scientist — to the test and rebukes the issues he claim get ignored by scientists.
Ask a climate scientist How does water vapor cause global warming?
As part of your summer reading, delve into these questions on CO2, global warming and what levels of CO2 are “safe” or “traditional”, the latest by Amber Jamieson and Rooted’s ‘Ask a climate scientist’ series.
Ask a climate scientist Is ‘natural’ climate change just as bad as ‘man-made’?
So what happens if we finally get all the climate policies into action, cut down carbon emissions, sign a global agreement etc and then Mother Nature throws us severe droughts, floods and other major natural disasters anyway? Amber Jamieson asks a group of climate scientists.
Ask a climate scientist How is the global average temperature calculated?
A State of the Climate – Global Analysis report declared Jan-Oct 2010 as the hottest period on record just last month. How is an “average” temperature found in a planet where there is no such thing as “typical”? Amber Jamieson asks the scientists.
Ask a climate scientist Was Greenland actually green?
Let’s get global warming and long-cycle natural climate change put in a little historical perspective for us today. Yes, the Medieval Warm Period and whether Greenland was actually green will be examined by two different climate scientists, writes Amber Jamieson.
Ask a climate scientist Even if we reverse climate change, what damage can we expect?
How do you prove climate change is a fact? And if it is, what damage can we expect? It’s a thoughtful and fascinating round of climate science questions today, writes Amber Jamieson.
climate change Ask a climate scientist: the Tamas edition
Got a question about climate science? We’re getting climate scientists from the American Geophysical Union to answer them for you, with three questions from well-known Crikey climate sceptic commenter Tamas Calderwood.
Why is the BBC ignoring climate change?
It’s incredible that Richard Black, environment reporter for the BBC, can report on rising global temperatures and melting ice caps without addressing the issue of climate change. But he, shockingly, manages to do just that…
IPCC warned: focus on the science, not policy
It’s been a gloomy year for the UN’s Intergovernmental Panel on Climate Change (IPCC) and a damning review of its processes and procedures released this week wouldn’t have helped lift the fog. Amber Jamieson explains.
A climate storm for investors
A moment is approaching when science and markets will collide, but then merge, with chilling consequences for investors who miss the moment and great excitement for those who are well prepared, writes Paul Gilding.
An open letter to climate sceptics from scientists
250 members of the National Academies of Science have published a letter hitting back against the assaults and “McCarthy-like threats of criminal prosecution” against climate scientists over the Climategate scandal.
Your Say: Daily Mail readers' feedback: A corrupt storm in a tea-cup
Crikey readers weigh in on the Melbourne storm salary cap scandal and Carl Williams — is Victoria the new corrupt Queensland? Plus climate change deniers and people smuggling.
Crikey Says: Climategate exonerated. Pity no one’s listening
It never pays to withhold information, as the University of East Anglia scientists behind the Climategate non-scandal have realised. Too bad the world isn’t paying attention now.
Senator McGuaran vs the Giant Space-Tarantulas from Pluto
Is Climate Change truly-ruly a thing? We may never know!
