Climate Change Threatens Productivity
Hotter working conditions associated with climate change threatens to erase more than $2.0 trillion in annual productivity by 2030 according to a new UN report, "Climate Change and Labour: Impacts of Heat in the Workplace."

Little Doubt About Great Barrier Reef Bleaching Cause
Around 93% of Australia's Great Barrier reef has experienced some degree of bleaching. The event was made 175 times likelier by human-caused climate change. Most unsettling is that it could be a regular phenomenon in just 18 years.

More Coal Power Cutbacks In China
China's government has announced a moratorium on construction of new coal-fired power plants in areas with surplus power. Even some already approved plants in a number of provinces won't be permitted to commence construction until at least 2018.

Polar Bears' Perilous Swims
Tracking of 100 polar bears in Hudson Bay and the Beaufort Sea showed nearly 70 percent swam more than 49 kilometres - a 25% increase over 2004. This has been attributed to less sea ice to support the bears. For old and very young bears, marathon swims can result in death and even fit bears can lose a lot of their condition.

Earth Reaches "Peak Carbon"
Professor James Curran says  global atmospheric concentrations of greenhouse gases are such that the Earth's ability to absorb ever-increasing emissions may have been comprised. In other words, we've reached “peak carbon”.

175 Countries Sign Climate Agreement
175 countries have signed the Paris Agreement, which was brokered last year. The U.N. states the event marked the larges number of nations to sign an international document in a single day. 

Has Climate Change Made Weather In The USA More Agreeable?

93% Of Great Barrier Reef Affected By Bleaching
The bleaching event on Australia's Great Barrier Reef is worse than thought. Only 7 per cent of this natural wonder has been left untouched by bleaching caused by the loss of algae from the corals due to significantly higher than average sea temperatures.

NZ Climate Policy A "Bloody Waste Of Time"
A Greenpeace NZ climate campaigner says a report from the Morgan Foundation that claims New Zealand's government has allowed businesses to buy fraudulent carbon credits from Russia and Ukraine is proof the country's emissions trading scheme is a "total bloody waste of time".

Australians Threatened By Rising Oceans
The majority of Australians live reasonably near the coastline and around 80 per cent of the population that does could be threatened by the impacts of rising sea levels by the end of this century. A set of maps indicate what this inundation may look like.

Cloud Cooling Effects Overstated
A NASA survey has found the cooling effects of clouds have been overstated and increased cloud won't slow climate change. The survey has also concluded that temperature increases could occur 25% faster than previously estimated.

Melting Ice Affecting Earth's Rotation?
Changes in Earth’s climate may be slightly moving the location of the planet’s spin axis, or axis of daily rotation; with much of this effect due to the melting of polar ice and the resulting redistribution of mass.

Australia First Paris Climate Agreement Signatory?
Once a climate change action recalcitrant, it seems Australia may be among the first countries to sign the Paris agreement on climate change. The agreement seeks to limit global warming to "well below" 2C, aiming for 1.5C.

NJ Growing Season Extends
Growers parts of New Jersey are seeing extended seasons due to climate change. Spring is starting around two weeks earlier and ending two weeks later.

Fungi As A Climate Change Marker
Two types of fungi respond differently to climate change and NASA's Jet Propulsion Laboratory now has a method to detect these types from satellite images of forest canopies, which will help gauge the potential impacts of climate change. 

Global Warming Impacting Birth Rates
Global warming has led to lesser sex frequency and consequently decreased birth rates in the United States.

Climate Change's Varying Impact On Birds
380 American bird species and approximately 145 European bird species were affected by climate change between 1980 and 2010; with some thriving and others experiencing significant decline.

Pueblo Civilisation Collapse And Climate Change
Four major phases of the Pueblo civilisation's societal collapse all coincided with periods of climate change.

Sea Level Rise Predictions Doubled
Climate scientists warn sea levels could rise 50 cm (20 inches) more this century than anticipated due to ice in the Arctic melting much faster than previously estimated.
