The 2015 UN climate conference in Paris (COP21) opened with the largest gathering of world leaders in history, and closed with adoption of the Paris Agreement, a new global accord on tackling climate change.
The Agreement marks the first time that virtually every country on Earth has pledged to constrain its greenhouse gas emissions with a view to keeping global warming since pre-industrial times below the commonly-used ‘danger threshold’ of 2 Celsius.

Eliminating single-use plastic products has become a cause célèbre over the past few years, but some in the environmental community complain it's a distraction from the bigger issues. Here's why they're wrong.
Scattering aerosols in the sky would cool the planet, but it would block crucial sunlight for plants.
When it comes to global health, the world has made remarkable strides over the past two decades. There has been unprecedented progress vaccinating kids, treating diseases and lifting millions out of poverty. The childhood death rate has been slashed in half since 2000. Adults are living an average 5 1/2 years longer.
Now scientists say these successes are under serious threat from climate change. The warning comes in a sweeping new study in the journal The Lancet. It's the latest in an annual — and evolving — effort by researchers from more than a dozen universities as well as the World Health Organization to track the health impacts of climate change.
The Charney report... Although we now have hard proof—one-in-3.5 million chance-of-error certainty, known as five sigma certainty, which is about as close as science gets to a sure thing—of warming as a phenomena, a report released in 1979 "understood most of what was going to happen subsequently," Santer says.
Bill Gates has committed his fortune to moving the world beyond fossil fuels and mitigating climate change.
Two options for dealing with climate change — reducing greenhouse gas emissions through a global agreement, and geoengineering proposals such as injecting sulfur into the stratosphere — tend to dominate current thinking. But there is a “third way” that is almost entirely neglected in political negotiations and public debate. It involves capturing carbon dioxide from the atmosphere and storing it or using it to create things we need. Because of the scale of the climate problem, I believe that in coming decades third-way technologies will become a major focus of activity.
Does one major volcanic eruption generate more climate-altering gas than that produced by humans in their entire history?
Climate change has largely been defined as an environmental issue, with the worst effects decades or centuries away. But a sobering new report from a commission convened by the medical journal The Lancet, released Monday evening, could change that assessment.
The new report says that climate change is already harming human health on a vast scale.
We are very far from the knowledge needed to make good climate policy, writes leading scientist Steven E. Koonin
Climate change is an immense and multifaceted global challenge, likely to change the planet we call home and our very way of life. In some of the most industrialized settings in the world as well as in the most vulnerable areas, people may find they can no longer live in places they have called home for generations.
I recently wrote about geoengineering as a strategy to deal with climate change and carbon dioxide emissions. That drew comments from people who confuse this scientific process with the unscientific theory of "chemtrails." Some also claimed the column supported geoengineering, which it didn't.
GeoMedicine will probably serve as a catalyst for future human migration from one part of the globe to another in the quest for minimizing personal health risks. And, it may be sooner than you think!
The world is getting hotter, and humans are responsible. That's the short version.
When people say global warming, they're typically referring to the rise in average temperature of the Earth's climate system since the late 19th century.
Those who want to lend a hand stand to do much good by acknowledging that climate change is occurring.
Not all opinions are created equal. So why do news media so often go out of their way to place those hocking scientifically unsupported fringe beliefs on the same footing as those espousing the near unanimity of the scientific community?
VICE founder Shane Smith travels to the bottom of the world to investigate the instability of the West Antarctic ice sheet and to see first hand how the continent is melting -- and VICE follows the rising oceans to Bangladesh for a glimpse into the world's underwater future. From the UN Climate conference to the People's Climate March to the forces that deny the science of global climate change, this special extended episode covers all sides of the issue and all corners of the globe, ending with a special interview with Vice President Joe Biden.
Fifty million years ago, temperatures soared to unprecedented levels and the seas became a staggering 12C hotter than today. But researchers have found this massive warming had little to do with carbon dioxide, the main cause of today's climate changes. The trigger was instead rising levels of methane, ozone and nitrous oxide, gases that are accorded relatively scant attention by current climate treaties.
Do we all have to go vegan to save the world?
Very few scientists are Republicans. And it's no wonder when you consider how Republican lawmakers are walking and talking when it comes to science. But while this may be politics as usual, it's no good for any of us—including Republicans themselves.
Might the result of one particle—or a dozen, or a hundred—be negligible in relation to human health? Sure. But put enough particles out there, and things change.
Obama’s Clean Power Plan would have averted asthma attacks. Trump wants to undo it.

Explaining climate change science & rebutting global warming misinformation
Scientific skepticism is healthy. Scientists should always challenge themselves to improve their understanding. Yet this isn't what happens with climate change denial. Skeptics vigorously criticise any evidence that supports man-made global warming and yet embrace any argument, op-ed, blog or study that purports to refute global warming. This website gets skeptical about global warming skepticism. Do their arguments have any scientific basis? What does the peer reviewed scientific literature say?
