Climate Change update

The world is running out of time to deal with climate change, the World Meteorological Organisation has warned, after new figures showed a surge in atmospheric carbon dioxide has seen levels of greenhouse gases reach record levels A new report by the WMO said concentrations of carbon dioxide in the atmosphere have grown at their fastest rate since 1984.

The head of the United Nations’ weather agency, Michel Jarraud, said there is no doubt the climate is changing because of the burning of fossil fuels. “We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels,” Mr Jarraud said in a statement.

World Meteorological Organisation’s report the

  • Concentrations of carbon dioxide in the atmosphere have grown at their fastest rate since 1984.
  • Atmospheric concentrations of greenhouse gases, including carbon dioxide, methane and nitrous oxide broke fresh records in 2013.
  • Carbon dioxide levels soared to 142 per cent of pre-industrial levels.
  • Radiative forcing, or warming effect from greenhouse gases increased 34 per cent from 1990 to 2013.
  • Current ocean acidification levels unprecedented at least over the last 300 million years.

“We must reverse this trend by cutting emissions of CO2 and other greenhouse gases across the board. We are running out of time.”

Bureau of Meteorology Media Statement

Numerous media stories have questioned the methods used by the Bureau in regard to Australia’s climate record.

Adjusting temperature data, a process known as homogenisation, is carried out by meteorological authorities around the world as best practice, to ensure that climate data is consistent through time.

As our data preparation reports explain, a key requirement for compiling and then analysing a long-term record of daily maximum and minimum temperatures for any given site is assuring that the temperature records are not artificially biased by effects that are not climate-related, such as:

  1. A shift in the location of the station (for example, from a post office to an airport);
  2. A change in the environment around the station (for example a tree grows, a structure is built, a lawn is irrigated); and
  3. A change in measurement method (for example, from a manual instrument to a recording electronic instrument).

Comparison between adjusted and unadjusted temperatures

Both adjusted and unadjusted temperatures show that Australia’s climate has warmed. Since 1955 adjusted and unadjusted data are virtually identical. It is during this time that most of the warming has occurred in Australia.

That marked a hike of 2.9 parts per million between 2012 and 2013 alone – the largest annual increase in 30 years, according to the Greenhouse Gas Bulletin.

August Weather 2014

A series of high pressure systems in the first half of the month tempted us to feel that Spring could not be far away. It was ideal holiday weather. A number of low pressure cells prevailed for the remainder of the month, with some areas receiving heavy falls of rain with a thunderstorm or two. At Maleny we had two consecutive days with torrential rainstorms on 23rd and 24th respectively with 124mm to fill many near empty water tanks. On Wednesday 27th at 2.45pm we had a thunderstorm with hail. Total rainfall for the month was 230.2mm.

August Rainfall data is incorrect due to instrument failure

Please note all daily rainfall figures from our automatic wireless rain gauge during August are incorrect due to a malfunction of the instrument The correct figures are given below. The error was brought to my attention by David  – a vigilant weatherwatcher. Thank you, David.    Normally I carry out  a quality check on monthly weather data but August was missed due to ill-health.

Strong earthquake hits northern California

Ten days after the supermoon passed close to earth a 6.0-magnitude earthquake has rocked parts of northern California, injuring dozens of people, damaging historic buildings and setting some homes on fire. The biggest quake in the region in 25 years jolted many residents out of bed when it hit at 3:20am (8:20pm AEST). The earthquake was centred about 10 kilometres south of the city of Napa. Three people were seriously injured, including a child who suffered multiple fractures after a fireplace fell on him, One local hospital said it had treated 89 patients following the earthquake.

Most damage on Sunday, appeared centred around Napa, a famous wine-producing region and a major tourist destination in northern California. It was the largest to hit the area since the Loma Prieta quake in 1989, which killed 63 people and caused $US6 billion in property damage. That quake measured 6.9, while the famous one that levelled San Francisco in 1906 measured 7.8.
