The Orbiting Carbon Observatory satellite makes precise measurements of Earth’s carbon dioxide levels from space.
Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?
Evidence shows electric vehicles have significant economic, social and health benefits.
Despite the overwhelming evidence that electric vehicle technology can deliver huge benefits, misinformation continues to muddy debate. Let's look at the facts.
A powerful heat-trapping gas, methane is released from the natural gas delivery infrastructure.

Two energy scholars who have studied the extent of methane leaks in the oil and gas industry explain what rescinding methane emissions regulations will mean to the climate and industry.
Researchers are keen to travel abroad but air transport makes a significant contribution to global greenhouse gas emissions.
The adverse environmental impacts of academic travel are known. It is now up to institutions to determine how to adapt to these impacts.
Energy Minister Angus Taylor has sought to downplay quarterly figures showing Australia’s emissions are still rising, attributing the result to the production of gas for export.
Australia is one of the sunniest and windiest countries on the planet, but emissions are still rising. How do you justify that?
In India, air conditioning system vendors waiting for customers during an episode of high heat.
As our planet warms, the number of air-conditioning units worldwide is expected to triple by 2050 – yet their use drives climate change. So how can we break the cycle?
On June 5-6, 2012, NASA’s Solar Dynamics Observatory collected images of one of the rarest predictable solar events: the transit of Venus across the face of the Sun.
This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
Policies to tackle climate change will make it more expensive not to act.
It is vital to find alternative and sustainable sources of protein to meet the considerable challenge of ensuring food security for the future.
Insects are high in protein and rich in other nutrients and, unlike beef and other livestock, have little impact on climate.
A seismic line (petroleum exploration corridor) traverses a wetland in northern Alberta.
Petroleum exploration in Alberta has disturbed more than 1,900 sq. km of wetlands in Alberta, boosting emissions of methane: a potent greenhouse gas.
Carbon offsetting is one way of doing it – but sometimes the simplest methods work best.
Very beautiful, and useful too.
An expert explains all the wonderful ways the atmosphere protects life on Earth.
It can be tempting to point fingers, but people with other priorities aren’t necessarily bad.

In the end, climate policy didn't swing the federal election, and for those on the losing side it can be tempting to play the blame game. But listening and respect are much better ways to move forward.
The Cape Grim observatory, home of the ‘world’s cleanest air’… and rising greenhouse gases.
Carbon dioxide levels in the atmosphere are at 414 parts per million. But thanks to a recalculation of methane's warming power, the total amount of greenhouse gases is now equivalent to more than 500.
The principles that drive financial markets emphasize short-term profits at the cost of long-term benefits.
Investors are increasingly concerned about climate change, but for the markets to deploy their full capacities, the dominant principles that guide them need to be revised.
Farm ponds can act as greenhouse gas sinks.
New research finds that farm ponds actually capture nitrous oxide; this finding can be useful in combatting climate change.
The exploitation of fossil fuels emits CO₂, the main cause of global warming.
The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.
The Rhenish Brown Coal Field in Germany. Germany is one of 18 developed countries whose carbon emissions declined between 2005-2015.
Reducing emissions doesn't have to conflict with a growing economy, as these 18 developed nations show.
While countries recognise the urgent need to reduce their greenhouse gas emissions by favouring greener energies, the ever-increasing demand for electricity has led to rising coal consumption.
Corn cobs dried up after a drought in eastern France in 2015.
The climate issue cannot be considered less urgent than the social or economic crisis.
