What caused the ‘pause’ in global warming?

Many people around the world, in certain locations, have asked, “where is global warming?” This is because they have experienced very cold wintry conditions and weird weather that they do not associate…

No, the Bureau of Meteorology is not fiddling its weather data

Over the past week or so, the Bureau of Meteorology has stood accused of fudging its temperature data records to emphasise warming, in a series of articles in The Australian. The accusation hinges on the…

Don’t dismiss a 2014 ‘super’ El Niño just yet

It looks like it’s all over bar the shouting for the chance of this year bringing on a “super” El Niño. Or is it? The Bureau of Meteorology has brought the odds of an El Niño event down to 50%, from 70…

Explainer: El Niño and La Niña

We wait in anticipation of droughts and floods when El Niño and La Niña are forecast but what are these climatic events? The simplest way to understand El Niño and La Niña is through the sloshing around…

US cold wave implies nothing about global warming

The central and eastern US has just been in the midst of a major cold wave, with large regions dropping below zero F (-17.7C) and wind chills reaching below -30F (-34C). That is fact. The problem is that…

Women worse off when it comes to natural disasters

The Philippines. Pakistan. New Orleans. Sri Lanka. All have suffered catastrophic disasters in recent times. And the emergence of “climate refugees” – populations displaced by extreme weather events…

2013 was Australia’s hottest year, warm for much of the world

The Bureau of Meteorology has confirmed 2013 as Australia’s hottest year since records began in 1910. Average temperatures over the continent have been 1.2C above the 1961-1990 average, breaking the previous…

Drought conditions return to Australia’s eastern states

While much of Australia has received average to above average rainfall over recent months, parts of Australia such as western Queensland are in the middle of a drought. Drought has been a feature of the…

Explainer: what is climate sensitivity?

Humans are emitting CO2 and other greenhouse gases into the atmosphere. As these gases build up they trap extra heat and make the climate warmer. But how much warmer? Scientists have long understood that…

How cold has it really been in the northern hemisphere?

If you are one of the many people with a larger than normal heating bill for recent months, you would probably be under the impression that it has been exceptionally cold in the northern hemisphere. We’ve…

Predicting El Nino: a tale of two authorities

Over the last two summers, Eastern Australia has experienced two of the hardest hitting La Niña events since 1974. Widespread floods resulted across great swaths of the country. As expected, the La Niña…
A precise weather forecast, months in advance, will never be possible. Matt Smith

A chaotic beast, probably: wacky weather and climate forecasting

“Prediction is very difficult. Especially about the future” – so said Neils Bohr, the Danish physicist and 1922 Nobel Prize winner. And you know what? I think the bloke was onto something there, especially…

Explainer: climate modelling

We know the climate is changing because that’s what climate models tell us. But what exactly is a climate model, and are they cutting-edge science or modelling madness? What is a climate model? Climate…

Why academics should steer clear of public debate

The most important issue raised by Lord Monckton’s controversial appearance on two Western Australian campuses is not the limit of free speech or Monckton’s scientific competence. Rather it is whether…

Who’s afraid of big, bad coal? Al Gore’s ‘climate reality’ is a pointless fairytale

With the momentum of his Inconvenient Truth gradually fading, Al Gore has launched a new climate change action campaign - the Climate Reality Project. The centrepiece of the campaign is a day of action…

The greenhouse effect is real: here’s why

CLEARING UP THE CLIMATE DEBATE: Bureau of Meteorology scientist Karl Braganza explains why we know the climate is changing, and what’s causing it. In public discussions of climate change, the full range…
