Climate Science

  • How climate change may be driving extreme weather

    Scientists say climate change could be altering the jet stream in a way that causes extreme heat waves, droughts, and flooding.

  • Climate science slashed in Trump budget. Why does that matter?

    America has a history of funding basic science at the federal level, on the notion that it pays off for society. The Trump budget challenges that view – including on climate research. 

  • Up to half of Arctic melting can be explained by natural changes

    'But you can't use this as an excuse' to write off the bigger trend in warming, says one of the study's co-authors.

  • How climate influences weather: six questions

    From extreme rains in some places to early spring in others, weather events prompt questions about what role climate change may be playing.

  • In a time of division, could science find a way to unite?

    At an annual gathering, concerned scientists discuss how to navigate distrust and make science for everyone.

  • Scientists drawn into politics, in a bid to defend science

    Concern in the science community rose this week about possible Trump administration curbs on researchers. Responses range from defending facts to actually entering the political fray.

  • The confusing, wild world of science under the Trump administration

    The first week of the Trump administration saw scientists going rogue over concerns about policy. But it also brought distortion of the facts.

  • Decrying 'post-truth' climate politics, scientists test activist waters

    Typically, scientists are reluctant to engage in what could be perceived as political activism. But many researchers are now pushing back against what they call unprecedented attacks on climate change research by the Trump administration.

  • On global warming, Trump nominees try having it both ways

    Cabinet candidates aren't calling climate change a 'hoax,' but they're taking on climate science by emphasizing a lack of modeling precision and disagreements among scientists.

  • New Energy Dept. guidelines: Changing culture or political ploy?

    Scientists can now speak freely to the media and publish in scientific journals. The guidelines may set the course for the upcoming confirmation hearing for Energy Secretary – and the department's next four years.

  • Energy secretary seeks to lock in free speech for DOE scientists

    The new policy, which Ernest Moniz says was in the works before Donald Trump won the presidency, says scientists 'are free and encouraged to share their scientific findings and views.'

  • Short-term greenhouse gases, long-term impact: What does that mean for Earth's oceans?

    A new study finds that greenhouse gases such as methane that break down quickly in the atmosphere may have a greater effect on warming oceans than was previously thought.

  • What really happened during the supposed climate change 'hiatus'?

    Researchers have independently replicated NOAA's recalibration of sea surface temperature data to uncover what really happened from 1998 to 2012.

  • Sea ice hits record low: Why is that a big deal?

    While the sea ice melt does not directly contribute to sea level rise, it does hold direct consequences for the whole planet.

  • Attack on climate action under Trump? It happened in Canada.

    Donald Trump won't be the first person to lead a Western democracy after a campaign dismissive of climate change. Canada and Australia have been there before.

  • Calculating your role in melting Arctic sea ice: How the CO2 emissions add up.

    Climate scientists have calculated just how fast humans' carbon emissions are melting Arctic sea ice in a new study. Just 75 miles in a fossil-fuel powered car equals one square foot of ice melted Arctic ice.

  • CO2 levels hit 400 ppm milestone: A prompt to turn Paris deal into action?

    The UN World Meteorological Organization has said the world has passed 400 p.p.m., a symbolic carbon dioxide threshold. The UN announcement comes two weeks before a climate change summit in Morocco. 

  • 'Consensus' on climate change: what that does and doesn't mean

    Agreement on basics of climate science is very strong, while there is much less certainty about specifics such as how fast temperatures or sea levels can be expected to rise.
