Most Comprehensive Paleoclimate Reconstruction Confirms Hockey Stick

By Stefan Rahmstorf via Scilogs The past 2000 years of climate change have now been reconstructed in more detail than ever before by the PAGES 2k project. The results reveal interesting regional differences between the different continents, but also important common trends. The global average of the new reconstruction looks like a twin of the…

Does Sea Ice loss create the condition for an emerging permanent El Nino state?

Recently Doug asked: “…my question is, how far could this phenomenon go? What is the “end” state? Is it possible for example that we could find the jet stream staying in place for months at a time, years, decades? How wavy could this waviness become?” A main theme of Sea ice loss seems to be…

Past decade saw unprecedented warming in the deep ocean

By Phys.org: From 1975 on, the global surface ocean has shown a pronounced-though wavering-warming trend. Starting in 2004, however, that warming seemed to stall. Researchers measuring the Earth’s total energy budget-the balance of sunlight streaming in compared to the amount of light and heat leaving from the top of the atmosphere-saw that the planet was…

Understanding the long-term carbon-cycle: weathering of rocks – a vitally important carbon-sink

By John Mason / SkepticalScience   above: the processes of the long-term carbon-cycle that this post explores. Graphic: jg. This post delves into the long-term carbon cycle that involves the interactions of the atmosphere with rocks and oceans over many millions of years. Because of its length, I’ve broken it up into bookmarked sections for…

Melting Sea Ice in the Arctic

Five Myths About Arctic Sea Ice http://sites.agu.org/sharingscience/f… Changes in Arctic sea ice coverage are happening at unprecedented rates, with 2012 setting a new record low for sea ice extent. Our ability to predict changes of sea ice loss and understand the impacts on society, from commercial shipping to resource availability, will be driven by further…

Extreme Weather From Mother Nature

Flooding, tornadoes, hail and fire are in the forecast — and with costly outcomes. ABC News: ‘Scientists Say Human-Caused Climate Change Is … Creating More Heat Waves, Droughts And Intense Downpours’ Here’s the transcript: And once again tonight, flooding, tornadoes, hail, and fire as the nation takes another punch from mother nature and climate. ABC’s…
