Skeptical Science: New study: global warming keeps on keeping on

As humans continue to dump heat-trapping gases like carbon dioxide into the atmosphere, the Earth continues to warm. In fact, it has been warming for decades and we now routinely hit temperatures that are 1°C (about 2°F) above the temperatures from 100 years ago.

But despite what we may expect, temperatures across the globe don’t rise little by little each year in a straight line. Rather,…

Skeptical Science: Humans on the verge of causing Earth’s fastest climate change in 50m years

A new study published in Nature Communications looks at changes in solar activity and carbon dioxide levels over the past 420 million years. The authors found that on our current path, by mid-century humans will be causing the fastest climate change in approximately 50 million years, and if we burn all available fossil fuels, we’ll cause the fastest change in the entire 420 million year…

Skeptical Science: New study shows worrisome signs for Greenland ice

As humans put more heat-trapping gases into the atmosphere, like carbon dioxide, ice around the planet melts. This melting can be a problem, particularly if the melting ice starts its life on land. That’s because the melt water flows into the oceans, contributing to rising sea levels. Right now there are three main reasons that sea levels are rising. First, as ocean waters heat, they expand.…

Skeptical Science: Scientists can be advocates and maintain scientific credibility

Scientists are often hesitant to engage in what might be considered “advocacy,” for fear of losing credibility with the public.

Skeptical Science: New study links carbon pollution to extreme weather

It was only a few weeks ago that I wrote about changes to extreme weather in a warming world. That prior article dealt with the increase of extreme precipitation events as the Earth warms. I termed the relationship a thermodynamic one; it was driven by local thermodynamic processes. But extreme weather can also occur because of large-scale changes to the atmosphere and oceans. This issue is the…

However, just recently the Energy Information Administration (EIA) announced that transportation emissions have…

It's a simple bet asking, "Will the next 2011-2020 decade be warmer than the previous 2001 – 2010 decade?" We're now over half way through this bet and here's where we stand.

The general consensus gleaned from the Paris Climate Summit in 2015 is that in order to halt the relentless march of climate change…
