Weâ€™ve tend to stay neutral when it comes to the global climate change debate, although we have tried to arm you with the information we believed you, as project managers, need to make sure you can take advantage of any projects that may arise as a result of any mitigation strategies. Today, we heard about a couple of disturbing reports due out over the next several months. Their titles were pretty ominous so we decided to dig a little deeper.
Take a look at some of these headlines and reports to be released and see if you donâ€™t agree that they are unnerving;
NOAA: Past Decade Warmest on Record According to Scientists in 48 Countries
Earth has been growing warmer for more than 50 years.
And this one a report that is indicative of what is to come.
The Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation.
The title says that those extreme events we have been experiencing, a major snow storm in the northeast in October 2011 for instance, are going to continue and we need a risk mitigation process to address them. Further, we will need to â€œadaptâ€ to these changes.
Another report coming from the Intergovernmental Panel on Climate Change (IPCC);
Special Report on Renewable Energy Sources and Climate Change Mitigation
And finally, an interview from a scientist who has not only been one of the questioners of global climate change, but also his study was partially funded by an organization made up of climate change skeptics. Dr. Richard Muller, professor of physics from the University of California, Berkeley, and founder of the Berkley Earth Surface Temperature Foundation, undertook an independent two year study of global climate change.
It was not that he himself was a sceptic, he just didnâ€™t believe the likes of Tom Friedman and Al Gore because Dr. Muller believes their contentions were not truly science based. Here is part of the interview between Dr. Muller and Eleanor Hall with Bronwyn Herbert from the Australian Broadcast Network (ABC). You can hear the entire interview here.
BRONWYN HERBERT: Richard Muller says he wasn’t convinced the earth was warming, and set out two years ago to find out if mainstream climate scientists were wrong.
RICHARD MULLER: Sceptics had raised legitimate questions. Many of the thermometers were of very poor quality and poorly placed. There were djustments being made to discontinuities in the data. There was perhaps undue influence from warming of cities, which was warm, but that’s not global warming.
BRONWYN HERBERT: He says he was particularly surprised that his results so closely correlated with previously published data from other teams in the US and the UK.
RICHARD MULLER: Somewhat to my amazement, none of the effects changed the answer. We wound up getting the same answer that the other groups had previously gotten for the amount of warming. It’s about 0.9 degrees Celsius over the last 50 years. The poor temperature quality data, even though it was at bad locations, the change in temperature I recorded was accurate. The urban heat island, just not that much area of the earth is urban. The temperature adjustments that people made, well those adjustments were made with more care than we could know, and in the end the adjustments didn’t bias the data. We picked five times as many stations as they did. Their selection of stations was sufficiently representative that it didn’t change the answer. So, in the end, the amount of global warming is what they said it was.
BRONWYN HERBERT: So do you now believe that global warming on earth is occurring?
RICHARD MULLER: Oh yes. I certainly believe that now.
And finally, from a report Agence France-Presse (AFP) states that a draft UN report three years in the making concludes that man-made climate change has boosted the frequency or intensity of heat waves, wildfires, floods and cyclones and that such disasters are likely to increase in the future.
â€œThe document being discussed by the world’s Nobel-winning panel of climate scientists says the severity of the impacts vary, and some regions are more vulnerable than others. Hundreds of scientists working under the Intergovernmental Panel for Climate Change (IPCC) will vet the phonebook-sized draft at a meeting in Kampala of the 194-nation body later this month.
“This is the largest effort that has even been made to assess how extremes are changing,” said Neville Nicholls, a professor at Monash University in Melbourne, Australia, and a coordinating lead author of one of the review’s key chapters. Mindful of an outcry by climate skeptics over flaws in an earlier IPCC text, those working on the document stress that the level of “confidence” in the findings depends on the quantity and quality of data available.
But the overall picture that emerges is one of enhanced volatility and frequency of dangerous weather, leading in turn to a sharply increased risk for large swathes of humanity in coming decades.â€
â€œIts publication coincides with a series of natural catastrophes around the world that have boosted the need to determine whether such events are freaks of the weather or part of a long-term shift in climate. In 2010, record temperatures fuelled devastating forest fires across Siberia, while parts of Pakistan and India reeled from unprecedented flooding. This year, the United States has suffered from a record number of billion-dollar disasters ranging from flooding in the Mississippi and Missouri Rivers to Hurricane Irene to the ongoing Texas drought. Large swathes of China are suffering from intense drought as well, even as central America and Thailand count their dead from recent diluvian rains.
Most of these events match predicted impacts of manmade global warming, which has raised temperatures, increased the amount of water in the atmosphere and warmed ocean surface temperatures — all drivers of extreme weather.
– It is “virtually certain” — 99-100% sure — that the frequency and magnitude of warm daily temperature extremes will increase over the 21st century on a global scale;
– It is “very likely” (90-100% certainty) that the length, frequency and/or intensity of warm spells, including heat waves, will continue to increase over most land areas;
– Peak temperatures are “likely” (66-100% certainty) to increase — compared to the late 20th century — up to 3.0 degrees Celsius (5.4 degrees Fahrenheit) by 2050, and 5.0 C (9.0 F) by 2100;
– Heavy rain and snowfall is likely to increase over the next century over many regions, especially in the tropics and at high latitudes;
– At the same time, droughts will likely intensify in other areas, notably the Mediterranean region, central Europe, North America, northeastern Brazil and southern Africa.â€ © 2011 AFP
