Sauropod Flatulence Caused Mesozoic Climate Change

Posted: May 12th, 2012 | Author: | Filed under: Cankler Science News, Climate Change | Tags: , , , , , | Comments Off on Sauropod Flatulence Caused Mesozoic Climate Change

Sauropod Flatulence Caused Mesozoic Climate ChangeWe’ve all heard the – possibly dubious – theory that bovine flatulence is adding to global warming? If not, the theory goes something like…

The abundance of methane evacuated from bovine rectum is apparently taken so seriously that in 2008 – at the height of greenhouse panic – the head of the international panel advising the world’s governments on how to reduce global emissions says people should stop eating red meat.

With cattle population sitting around 1.9 billion, cattle flatus accounts for about 30 per cent of the methane in the atmosphere, according to the US EPA, thats about 80 million metric tonnes a year, eeeew…

According to researchers, this isn’t the first time the planet has faced this particular problem. Researchers say dinosaur flatulence could have put enough methane into the atmosphere to warm the planet during the hot, wet Mesozoic era :: Read the full article »»»»

Wind Farms Linked to Localised Climate Change

Posted: April 30th, 2012 | Author: | Filed under: Cankler Science News, Climate Change, Science of Green | Tags: , , | Comments Off on Wind Farms Linked to Localised Climate Change

Wind Farms Linked to Localised Climate ChangeTurbulence created by wind farms causes air temperatures to rise directly around the supposed green energy producers, researchers say. Scientists including Associate Professor Liming Zhou from the State University of New York examined conditions around 2,358 turbines at four Texas wind farms.

Writing in the journal Nature Climate Change, Professor Zhou and colleagues reported a temperature increase of up to 0.72 degrees Celsius per decade at wind farm locations, compared to nearby areas. The wind industry in the United States has experienced a remarkably rapid expansion of capacity in recent years and this fast growth is expected to continue in the future.

While converting wind’s kinetic energy into electricity, wind turbines modify surface–atmosphere exchanges and the transfer of energy, momentum, mass and moisture within the atmosphere. These changes, if spatially large enough, may have noticeable impacts on local to regional weather and climate.

Oddly, researchers also found the effect to be greater at night than during the day. After discounting the impact of surface features such as vegetation, roads, light reflection and surface structures, the researchers concluded that the temperature change was caused by air turbulence generated by the turbines’ giant rotor blades. Professor Zhou said the study could help researchers better understand the impact of wind farms on local environments :: Read the full article »»»»

Climate Change: Humans Pumped Out 10 Billion Tonnes of Carbon Emissions in 2010

Posted: December 5th, 2011 | Author: | Filed under: Climate Change, Science, Science News, Science of Green | Tags: , , , , | Comments Off on Climate Change: Humans Pumped Out 10 Billion Tonnes of Carbon Emissions in 2010

Cankler-10-Billion-Tonnes-of-Carbon-EmissionsNew research has found global carbon emissions surged by a record amount in 2010 after falling during the international financial crisis.

The Global Carbon Project published its yearly analysis of carbon dioxide emissions in the journal Nature Climate Change today.

The report found that global carbon dioxide emissions increased by a record 5.9 per cent in 2010. The report says the overall atmospheric concentration of carbon dioxide is now at its highest level in 800,000 years.

At current rates, including the increase in emissions that has been occurring over the last few years and continuing and even accelerating this year, we have about 35 to 40 years to go, before we hit that limit of a total of 1 trillion tonnesRead the full article »»»»

IPCC Climate Assessment 2013

Posted: September 27th, 2013 | Author: | Filed under: Climate Change | Tags: , , , , | Comments Off on IPCC Climate Assessment 2013

IPCC Climate Report 2013It may have all but been leaked, massaged and misquoted in the months prior to today’s release, however the United Nations’ Intergovernmental Panel on Climate Change – IPCC – report remains by far the most important climate report card on the planet.

More than 600 scientists contributed to the report, which is the result of almost seven years work by climate scientists and policy-makers. It’s based on more than 50,000 contributions from around the globe, and an exhaustive peer review process.

Long-term global temperatures are rising, Arctic ice is shrinking, permafrost melt is increasing, and sea levels are rising. The United Nations’ chief science panel also says it is 95 per cent certain that humans are behind the planet’s rising temperatures. According to the IPCC, the report is a conservative outlook.

While average land and sea temperatures will continue to rise, the report suggests the planet is heating at a slower rate than previously predicted. The worst case scenario is for a sea level rise by almost 1 metre, and temperatures could rise by around 2 degrees Celsius.

The IPCC panel says mankind needs a carbon budget if we are to restrict a rise in temperatures, the report predicts that since industrialisation we’ve emitted more than half a trillion tonnes of carbon dioxide, by 2040 we’ll have doubled those emissions  :: Read the full article »»»»

New Study Says Climate Obsessives Swayed By Media

Posted: March 13th, 2012 | Author: | Filed under: Cankler Science News, Climate Change, Psychiatry | Tags: , , , , | Comments Off on New Study Says Climate Obsessives Swayed By Media

Cankler Science News - New Study Says Obsessives Swayed By MediaA new published study has highlighted how the media influences opinion on emotive issues. The study undertaken by the University of Sydney was carried out to investigate whether climate change had any impact on the nature of the obsessions or compulsions experienced by sufferers of Obsessive Compulsive Disorder – OCD

The study takes reference from a 1994 study which found that some children developed obsessive thoughts about Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome – HIV/Aids – once media reports on the virus became common place.

We suggest that mental health professionals need to be aware of, and assess for the presence of such concerns” the study recommended.

This latest study has found that many patients suffering with OCD are worrying about the effects of climate change and global warming. Dr Mairwen Jones and her co-authors looked at 50 patients attending an anxiety disorders clinic.

They found one-third of the patients had anxiety about the effects of climate change. The most common concerns were wasting water, gas and electricity, often leading to an obsessive checking to make sure utilities and appliances were switched off :: Read the full article »»»»
