Is there any merit to the studies that show that historical CO2 levels lag behind temperature, and not lead them?
Yes, there's merit to those studies, says Peter Hildebrand, Director of the Earth Science Division at NASA's Goddard Space Flight Center, responding to a question from Twitter (https://twitter.com/Seth_b_clark/stat...).
In the pre-industrial age, the CO2 response to temperature was that the temperature would go up and CO2 would go up. Or if the temperature went down, CO2 would go down. Because when the temperature rose, the whole biosphere revved up and emitted CO2. So we understand that process.
In the post-industrial age, the opposite is true. Increasing CO2 in the atmosphere is leading to increased temperature. So two different things happened, one pre-industrial, where temperature was driving the CO2, and post-industrial, where CO2 was driving temperature. Which means a completely different physical-biological process is going on.Published on Sep 24, 2013

Is there a pause in global warming?
This question was posed to Jet Propulsion Laboratory scientist Josh Willis as part of NASA's Ask A Climate Scientist campaign.
Josh gets asked a lot if there has been a pause in global warming, because temperatures aren't increasing as fast as they were a decade ago. No, he says, global warming is definitely still increasing (http://climate.nasa.gov/key_indicator...). We see more heat being trapped in the oceans, and sea levels are rising. Look at the sea level record for the last decade (http://climate.nasa.gov/key_indicator...). It's going up like gangbusters, hasn't slowed down.
There's not really a pause in global warming. Sometimes there's natural fluctuations and we warm up a little faster in one decade and a little slower in another decade, but global warming, human-caused climate change? Josh says, "that's definitely going right on up in there. We haven't slowed down at all."

This video uses animation, graphics, and video clips to illustrate and explain each of the "flow" and "storage" processes in the Hydrologic Cycle, more commonly known as the Water Cycle: precipitation, interception, runoff, infiltration, percolation, groundwater discharge, evaporation, transpiration, evapotranspiration, and condensation.

Janice Taylor of Kelowna, British Columbia, Canada addresses the practice of labeling behavior of children and the negative consequences of doing so. After growing up to a single mom in poverty and facing the challenges of difficult circumstances, Janice has turned her life experiences and education into a winning combination. She is pioneering the world of social networks with her creation of Just Be Friends Network Inc. with the aim to reduce the growing epidemic of bullying, cyber bullying and unhealthy relationships among children/youth ages 4-13.

Physicist Lee Smolin talks about how the scientific community works: as he puts it, "we fight and argue as hard as we can," but everyone accepts that the next generation of scientists will decide who's right. And, he says, that's how democracy works, too. More of his lectures on his Website here.

Sacha Warmi means "spirit woman of the forest" in the Kichwa language. A Female enchantress, she confers wisdom and beauty upon women, evoking the feminine spirit of nurturance and support for human life that arises from the Earth and Nature itself.
We hear a lot about how the Amazonian Rainforest is disappearing—but we don't hear much about how that affects the health of the people who once called it home.
By now it's an old story: Despite the international efforts that have taken place over the last 30-40 years to protect the Amazonian Rainforest and its indigenous peoples, ecological and cultural degradation continues at an alarming rate.
We invite you to create with us a beautiful and important project: the Sacha Warmi Center—an educational resource that will serve many people—located on the outskirts of the Amazonian Rainforest in the Pastaza region of Ecuador.
Donations accepted here.
Thank you for your generosity and support. Rosa Canelos and Didier Lacaze

Didier Lacaze with Rosa Canalos (Kichwa) founded the Sacha Warmi Center—an educational resource that will serve many people—located on the outskirts of the Amazonian Rainforest in the Pastaza region of Ecuador. It is part of PROMETRA (Promoción de la Medicina Tradicional Amazónica), a local Ecuadorian initiative created in 2005 by Didier and Rosa who was born in the village of Canelos and is Didier's wife.
Didier was interviewed by videographer Barry Heidt of Sustainability Action Media (SAM) as part of an online video campaign to increase the Indigenous Voices of Sustainability, co-sponsored by EarthSayers.tv, and focusing on wisdom keepers of Ecuador. Editing support by Norman Austin.
Most of the world still lacks adequate technology which hurts business growth, slows aid to disaster victims, and keeps people from communicating with each other. NetHope is the bridge across the technology gap. We bring together the world's leading humanitarian groups and high tech companies in a common cause, which multiplies the power of these groups. The narrator is Frank Schott, Global Program Director at NetHope.
