Scientists have long thought most nitrogen in Earth's ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
Scientists on Arctic sea ice in the Chukchi Sea, surrounded by melt ponds, July 4, 2010.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
Dust storms in the Gulf of Alaska, captured by NASA’s Aqua satellite.
There are more satellites than ever before, orbiting Earth and collecting data that's crucial for scientists. Why do some nations choose not to share that data openly?
Some information on the climate has been obscured.
Despite scientists' initial concerns, federal climate change data sets are still available. But other documents and web pages have changed over the last year.
MiMA: an open source way to model the climate.
The creation of climate models with open source code, available for anyone to use, has improved scientific collaboration and helped research get more efficient.

Research can be spun, within hours, into a story of past failure. In fact, it's a case of continuous improvement.
Trust is everything.
Politicians are always being told to trust what climate scientists are telling them. But can you have too much of a good thing? What happens when the exchange of ideas becomes too cosy?
The continent is home to 12 million penguins…and not much else.

The Antarctic Treaty was signed 58 years ago today, protecting the continent for peace and science.
By the age of 16, most teenagers have already made up their mind about climate change.
Players in the climate science game 'CO2peration' become a particle of sunlight, and travel on a journey to find out why we have liquid water at Earth’s surface.

Some claim that scientists avoid publishing results that go against the consensus on man-made climate change. But this is simply untrue.
The Day After Tomorrow’s apocalyptic depiction of climate change is a little embellished. But such storylines can ignite conversations with people that mainstream science fails to reach.

Climate scientists often bombard their audiences with facts and figures - a method of communication that often doesn't work. Perhaps this is where cli-fi can step in, with its compelling characters and just slightly embellished science.
Who set the guardrails on global temperature rise?
More and more research shows that we are likely to pass the 2 degree Celsius temperature limit much of the world has agreed on. Where did that limit come from, and what if we miss it?

The ice sheet is melting and permafrost is thawing. What's happening in Greenland will speed up climate change across the world.
When Tony Abbott went too far in his advocacy for the coal industry, his government faced a public backlash.
While climate denialism impedes policymaking in both the US and Australia, there are key differences in their political and public cultures.
In 2013, pro-science supporters rallied before a Texas Board of Education public hearing on proposed new science textbooks.

Thirty years after the Supreme Court ruled that creationism cannot be required in schools, 'creation science' is still taught in some schools. What are the implications for climate education?
Average carbon dioxide concentrations, Oct. 1 -
Nov. 11, 2014, measured by the Orbiting Carbon Observatory-2 satellite.
Why use satellites to study Earth's climate? Researchers leading a new mission explain how images from space will help them analyze which parts of the Americas soak up the most carbon.
Nobody can observe events in the future so to study climate change, scientists build detailed models and use powerful supercomputers to simulate conditions, such as the global water vapor levels seen here, and to understand how rising greenhouse gas levels will change Earth’s systems.
People worry Washington is losing respect for science and even the centuries-old scientific method. Two climate scientists explain how science can be done when talking about the future.
