Climate Change Could Increase Ozone Pollution 70 Percent By 2050

There may be a reason why emissions regulations that reduced air pollutants like sulfur dioxide, nitrogen dioxide and carbon monoxide haven't really led to a drop in ozone. A report from 2012 found that ambient levels of fine particulate matter had d ...

Climate: Explaining The Tree Ring Divergence Problem

The climate hockey stick, a popular visual metaphor for climate change, has received considerable attention. It depicts a slightly cooling trend in the Northern Hemisphere from 1000 A.D. until 1900 A.D. and then swings sharply upward in the last 80 years. ...

Now That Natural Gas Is Working, Methane Is Being Called More Damaging Than CO2

In 2007, after a marketing blitz for climate change during much of 2006 and the release of a new UN IPCC report, mentioning that methane had 23X the global warming effect of CO2 would get you shouted down and sternly reminded that CO2 lasts far longer. Th ...

Ride The Solar Winds, Ride The Lightning

There is new evidence to suggest that lightning on Earth is triggered by cosmic rays from space- and energetic particles from the Sun. How so? They linked increased thunderstorm activity on Earth and streams of high-energy particles accelerated by the sol ...

Can Droughts Now Be Predicted?

The weather is big news. No matter what is happening, too little or too much, someone is talking about that and then linking it to long-term climate disruption. The UN IPCC says not do to that, but if people will anyway, the big question is; how much accu ...

Buried Fossil Soils From Long Before Industrialization Are Deep In Carbon

Soil from thousands of years ago that is now deeply buried has been found to be rich in carbon, adding a new dimension to figuring out the planet's carbon cycle. The element carbon comes in many forms and cycles through the environment – land, sea an ...
