SEEKING THE SCIENCE
OO Global Warming Can Intensify Meandering Jet streams, Creating More Extreme Winters says a new study.
OO Greenhouse Gases Highest in 800,000 Yrs, Are Manmade – ancient ice cores now indicate.
Net radiation for Earth ( here for yrs 1985-1986 in Watts per square meter) is the most direct measure of how much heat the Earth is absorbing. Source: NASA.
Three Different Measures Needed to Accurately Assess Global Heatingreports Kate Ravilious at the UK Guardian. Surface temperature alone isn’t enough; ocean heat content (via buoys) is another important measure.
Finally, the net radiation absorbed by Earth (via satellites) is the most direct measure, notes the author of a recent published study, which shows that despite the fits and starts of surface temperature, both net radiation and ocean heat content are rising.
Drunken trees: Dramatic Arctic Signs Of Climate Change Are Occurringreports Brian Howard at National Geographic. The land of permafrost and forests is giving way to thermokarsts, collapsed areas of melted permafrost and tilting or fallen trees as roots lose their hold in these new swamps. Lakes are forming around hillocks, comprised of the meltwater from the permafrost. The change in landscape is stark and dramatic, emphasizing the dramatic change in climate underlying it.

Ocean Acidification Threatens Marine Food Chain says new research reportsOliver Milman at the UK Guardian. Other studies have already shown how rising CO2 sea levels makes it difficult for animals to grow skeletons or shells.
Not Nemo, too!! Clown fish and others are more likely to succumb to predators they can’t smell in more acidic seas under continued global warming. Credit Ritiks via Wikimedia Commons.
Now, US and Australian researchers have found that when fish are exposed to levels of CO2 expected under continued global warming, they are unable to distinguish the smell of predators and lose their fear of them, making them more likely to be eaten. This could cause major disruptions of marine food chains.
Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here. This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
