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 »»»»


Sexually Transmitted Infections Epidemic: Is Sex Education the Answer?

A community based sexual health group has raised the alarm about the level of risky sexual behaviour among young people, saying ignorance on the subject could make young Australians vulnerable to HIV/AIDS. Alischa Ross, the founder of Youth Empowerment Against HIV AIDS – YEAH – says her group sends volunteers into schools and public events such as music festivals to educate young people about safe sex. There has been a 20 per cent increase in the rate of infection among young people in the last three years, with chlamydia and gonorrhoea among the biggest culprits. Ms Ross says the trend points to more risky behaviour and widespread complacency. Ross says although HIV is not a huge problem in Australia, it will become more of an issue in the near future, looking at the trends of HIV and what we’ve seen happen worldwide for the last 30 years, is that where there are high incidents of Sexually Transmitted Infections, HIV follows D★D  READ MORE


Global Warming Atmospheric CO2 Link Questioned

Posted: November 25th, 2011 | Author: | Filed under: Climate Change, Engineered Life, Science, Science News, Science of Green | Tags: , , , , , | Comments Off on Global Warming Atmospheric CO2 Link Questioned

Global Warming Atmospheric CO2 Link QuestionedHigh levels of carbon dioxide in the atmosphere may have less of an impact on the rate of global warming than previously feared, a new study suggests.

Associate Professor Schmittner notes that many previous studies only looked at periods spanning from 1850 to today, thus not taking into account a fully integrated palaeoclimate data on a global scale.

The authors of the study stress that global warming is real and that increases in atmospheric CO2, which has doubled from pre-industrial standards, will have multiple serious impacts.

But more severe estimates that predict temperatures could rise up to an average of 10 degrees Celsius are unlikely, the researchers report in the journal Science.

The new study suggests temperatures will rise on average 2.3 degrees under the same conditions :: Read the full article »»»»


A Century of Extreme Storms

Posted: November 19th, 2011 | Author: | Filed under: Climate Change, Ecology, Science, Science News, Science of Green | Tags: , , , , , | Comments Off on A Century of Extreme Storms

CLIMATE CHANGEAs the Earth’s climate warms, United Nations scientists are predicting an increase in heat waves, rainfall and flooding, stronger cyclones and more intense droughts across the globe this century.

In a report released last week in Uganda, the United Nations Intergovernmental Panel on Climate Change – IPCC – urged countries to rapidly adopt disaster management plans to adapt to the growing risk of extreme weather. The report gives differing probabilities for weather events, but the thrust is that extreme weather is likely to increase and that the likely cause is humans.

The IPCC defines “likely” as a 66-100 per cent probability, while “virtually certain” is 99-100 per cent. The report says it’s virtually certain that increases in the frequency and magnitude of warm daily temperature extremes will occur on the global scale in the 21st century.

A 1-in-20 year hottest day is likely to become a 1-in-2 year event by the end of the 21st century in most regions. It is very likely that the length, frequency and intensity of heat waves will increase.  Heat waves would likely get hotter by 1-3 degrees Celsius by mid-21st century and by 2-5 degrees by late-21st century :: Read the full article »»»»

H1N1 Virus Simulated

Our  understanding of the universe is expanding in all directions, expanding outwards as we see more and more of the cosmos and inwardly as we learn more about the nano world. In the nano world the tools for capturing the action shots are improving but there are still a number of destinations we are unable to explore. Organic organisms – for example, influenza virus – are too delicate for the standard tools of nano exploration :: Read the full article »»»»
