The Australian Government had aimed to have its controversial Emissions Trading Scheme launched this year, but it says opposition in the Senate and little progress internationally since the Copenhagen talks means it needs to be delayed until 2013. Read more

April 26: Protest over proposed wood fired power plant
A small coastal Australian town will be powered by a wood-fired electricity plant even though it's claimed burning wood will generate four times more greenhouse gas emissions than burning coal. An environmental group has also said logging of native forests affects the hydrology of the region leading to less rainfall and as an effect; fewer trees. Read more

April 25: Copenhagen carbon commitments too weak
In an analysis published by the journal Nature, scientists say various country pledges to cut carbon under the Copenhagen Accord are likely to have committed to warming of  5.4 degrees Fahrenheit or more, compared to the deal's target of  3.6 F, which could result in even more frequent severe weather events and drought. Read more

April 24: Whale poop, krill, algae and carbon dioxide
Research from Australia's Antarctic Division suggests increasing populations of baleen whales and krill would have a positive effect ocean's ability to absorb CO2. Krill are rich in iron and when whales eat them, most of the iron is excreted back into the water, which algae feed - and algae are also absorb huge amounts of carbon dioxide. Read more

April 23: Ocean acidification rate "unprecedented"
The rate of ocean acidification caused by carbon dioxide emissions exceeds any known to have occurred in hundreds of thousands of years, according a congressionally requested study by the National Research Council. Studies on a number of marine organisms have shown that excessive carbon dioxide lowers sea water pH levels and impacts on affects biological processes, growth and reproduction. Read more

April 22: Nearly 3% of carbon emissions milk related
A recent study by the UN Food and Agricultural Organization (FAO) has found close to 3% of the world's greenhouse gas emissions come from the production of milk, including production, processing, and transportation of milk as well as the fertilizer, pesticides, and feed used in the dairy industry.

April 21 : Earlier Spring in the USA
What's become known as "Spring creep" is seeing the season starting an average 10 days earlier across the USA than it did 20 years ago. Spring creep is throwing ecosystems out of balance and sometimes providing more favorable conditions to invasive and non-native species. Read more

April 20: Iceland's volcano cranking carbon emissions
Iceland's Eyjafjoell volcano is emitting between 150,000 and 300,000 tonnes of carbon dioxide (CO2) per day; around the same amount as generated by a small to medium sized European country. However, volcanic eruptions generally contribute less than a third of one percent of global greenhouse gas emissions and are dwarfed by the level generated by humanity. Read more

April 19: Iceland's volcano won't slow global warming
Major volcanic eruptions of the past have been known to reduce temperatures globally due to vast quantities of ash in the atmosphere filtering out the sun's rays. Some scientists believe the current Iceland volcanic eruption isn't on a scale to have a marked global effect on temperatures. Read more

April 18 : Global warming threatens white honey
Already a rare product, Ethiopia's sought after white honey is becoming ever more scarce due to a lack of rain in the Tigray region. Bees need special flowers that only grow at high altitude to make the white honey, without which they simply switch to other flowers to make the normal colored substance. The region's bee population is also declining, with climate change and deforestation being the cause. Read more

April 17: March 2010 a temperature record-breaker
Regardless of cold snaps occurring in some regions, according to the National Oceanic and Atmospheric Administration (NOAA) the worlds combined global land and ocean surface temperature made last month the warmest March on record. Average global temperature for March 2010 was 56.3F (13.5C), which is 1.39F (0.77C) above the 20th century average of 54.9F (12.7C). Read more

April 16: The mystery of Earth's missing heat
The amount of heat coming into Earth's system is equal to the amount leaving it when climate is stable, but according to a U.S. National Center for Atmospheric Research report, humans pumping climate-warming greenhouse gases like carbon dioxide into the atmosphere has upset the balance. However, a gap has appeared and some heat is unaccounted for; which may come back to haunt us says the report. Read more.

April 15 : Global warming means longer allergy season
A new report from the National Wildlife Federation (NWF) states global warming will likely increase pollen counts in the eastern half of the USA. Higher levels of carbon dioxide in the atmosphere tend to accelerate plant growth and warmer temperatures are bringing on Spring earlier - an. average 14 days earlier than just two decades ago. Read more

April 14: Water shortages may force Indus Treaty review 
With ongoing water shortages due to climate change and demand looming, India and Pakistan may need to review a 50 year old treaty under which they share rivers originating from the Himalayas. Pakistan is heavily reliant on irrigation for food and fiber production and water availability per capita is now less than a third of what it was in the 1950's. Read more.

April 13: Australia : nuclear power "not sensible".
Climate Change Minister Penny Wong today reiterated that Australia will continue to rely on coal as a major source of power and that nuclear power is "not the sensible course" when it comes to the nation's domestic power generation. Read more.

April 12: Austria's disappearing glaciers
Almost 90 percent of Austrian glaciers shrank in 2009, some by as much as 46 metres. The winter was 0.2C warmer than average, the summer by 2.1C. Only seven were classified as stationary and a single glacier has advanced. Austrian glacier movement has been monitored for the last 119 years. Read more

April 11: Climate change agreement bickering continues
