We cross the 2C threshold at our peril.
2C is the officially agreed safe limit for global warming, but a recent expert finds 2C is still in the danger zone.

The risks of rising carbon emissions means fossil fuel firms need new strategies now - for the sake of their businesses as well as the planet.
Increasing emissions from Canada’s oil and gas sector will make Canada’s post-2020 pledge very difficult to achieve.
This month Canada revealed its post-2020 climate target as 30% below 2005 levels by 2030. But current policies make it unlikely Canada will achieve the target within the country.
The frontline of climate change.
Yet more doom and gloom from the bottom of the Earth.
Countries should make pledges to fund low-carbon research - such as developing solar technology - and development as part of global climate talks.

Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.

Until recently, tall wooden towers were an engineering impossibility. Following a breakthrough a few years ago, the sky is increasingly the limit.
It takes time, but this is how a real consensus is built.

There is a way for governments to find out the consensus on global issues such as climate change. But it involves painstaking, complex work, and an end to the adversarial clash of competing ideologies.
Australia needs a better guardrail to stop emissions increasing.
While the recent emissions reduction auction in Australia was a success, much more needs to be done to build an effective climate policy.
Nigerian youth celebrate presidential candidate Muhammadu Buhari’s victory. Youth unemployment will continue to threaten the continent’s growth.
How realistic are expectations about Africa’s economic prospects? There are several reasons why we should be both optimistic and cautious about the continent's future economic performance.
California has been inundated with stranded, hungry sea lion pups, a result of warm waters causing fish to move.
The "warm blob" of remarkably warm water in the Pacific is changing weather patterns and impacting marine life, providing clues to how ecosystems may change in a warmer future.
Australia has committed to a long-term global average temperature increase to no more than two degrees Celsius – yet often envisions a future in which its is a major coal exporter.
When it comes to climate change and Australia's economic future, different crystal balls can produce vastly different results.
Breaking the ice: while scientists increasingly understand why Antarctic sea ice is growing, it remains tricky to forecast.

Antarctica's sea ice is changing in ways that scientists didn't predict, and is now causing headaches for Antarctic stations.
Every year millions of birds migrate between Australia and the northern Hemisphere.
Five million shorebirds migrate between Australia and the northern hemisphere, threatened by habitat destruction, and rising seas. How can we protect this natural marvel?
Presidential debates around climate change will likely be a referendum on EPA proposals to lower carbon emissions from power plants.

The American public appear to be of two minds on climate change in politics: supportive of policy action but unconvinced climate change is an urgent priority.
The drop in oil has not sparked the nadir of green energy.
Contrary to economic theory, data shows that the latest drop in energy prices does not undermine investment in renewable energy.
Mitigation efforts could help alleviate the impacts of climate change on food security and agriculture in Africa.
Climate change is affecting all regions of the globe. But some places, such as Africa, are more vulnerable than others.
Rising sea levels are one of the clearest and most widespread manifestations of climate change.
Since 1993, satellites have been used as well as tidal gauges to monitor sea level. A new calibration of this satellite record now shows that the rise in sea level is gathering pace.
With sea levels rising, a managed retreat from the coastline is necessary.
In areas vulnerable to sea level rise and storm surges, developments are at increasing risk of inundation and permanent damage over coming years.
The cost of low emissions technology is falling faster than modelling five years ago expected, lowering the cost of reducing carbon emissions.
Despite solid results from the first emissions reduction fund auction, Australia hasn't yet got a climate policy to last.

Scientists and policy makers are struggling in some countries to gain the support that will lead to meaningful action on climate change. Could art be the answer?
