Subbing new risks for the current dyes’ dangers?
Less-toxic hair dye would be a great invention. But discounting the risks that come with nanoparticles could undermine other efforts to protect human health and environmental from their effects.
Canada has committed to cutting GHG emissions 30 per cent by 2030 from 2005 levels. Can Canada's oil capital lead the charge? New research shows it's within reach with bold actions on several fronts.
It turns out that the world is about 4,600,000,000 years old. That’s 4.6 billion years. That’s pretty old!

The world is made of tiny building blocks called 'elements'. Scientists have worked out how fast some elements change into other elements. That gives us a very big clue about how old the Earth is.
Pointing in the wrong direction.
A scheme in Wales to introduce personal carbon accounts could point the way to reduce emissions.

It's like one great big distillery up there.
Compressed glassy carbon could be used to make better bulletproof vests or new types of electronics.
Pollution has increased carbon in our soils - which is good for climate change. But this carbon may not stay there for long.
On June 1, 2017, President Donald Trump announced that he would take the U.S. out of the Paris Agreement, and that he could negotiate a “better deal”.
On June 1, Donald Trump announced that he would take the US out of the Paris climate agreement because it was "unfair" to the US. An economic analysis indicates otherwise.
Humans have burned 420 billion tonnes of carbon since the start of the industrial revolution. Half of it is still in the atmosphere.
Global warming and carbon emissions, left unchecked, could cause rising sea levels and displace almost 200 million people. But we can still prevent the worst case scenario if we act now.
Prime Minister Malcolm Turnbull spoke about clean coal at his National Press Club address.
In his speech this week to the National Press Club, Turnbull initiated a genuine “game-changer” in the debate about power generation in this country. It is instructive to focus explicitly on what he said…
An oil rig in Angola. The country could see big reductions in export and revenue from fossil fuels as the world transitions to clean energy.
The end of fossil fuels is approaching fast. But the question remains of what to do with those that remain, waiting to be sold.
China’s concerns about air pollution from burning coal is one reason behind the emissions slowdown.
