IPCC report on climate impacts: "It's time to get serious" The United Nations scientific panel on climate change today presented its latest report on the impacts of climate change, society's vulnerability to them, and the capacity and limits to adapt to the changing climate.
The Intergovernmental Panel on Climate Change report finds clear evidence that climate change is already having substantial and widespread impacts today but says strong and urgent action to reduce greenhouse gas emissions can reduce the risk of such impacts in the future.

Updating the Climate Big Picture. Posted on 23 December 2011 by dana1981 When discussing climate science and looking at individual pieces of evidence and common myths, it's easy to lose sight of the forest for the trees.
That's why The Big Picture is one of the pages featured prominently on the Skeptical Science homepage. However, we created that page over a year ago, so it's worthwhile to once again step back and take stock of what we know and what remains uncertain, and update the Big Picture. The Earth is Warming We know the planet is warming from surface temperature stations and satellites measuring the temperature of the Earth's surface and lower atmosphere. Figure 1: Indicators of a warming world Global Warming Continues And yes, the warming is continuing.
Contrary to what some would like us to believe, the planet has not magically stopped warming. Figure 3: Temperature data (with a 12-month running average) before and after the short-term factor removal Figure 4: Total global heat content. The Warming will Continue. Earth's geomagnetic reversal happened 41,000 years ago, new study claims. 41,000 years ago, a complete and rapid reversal of the geomagnetic field occurred.
As a consequence, the Earth nearly completely lost its protection shield against hard cosmic rays, leading to a significantly increased radiation exposure, a new study led by Dr. Norbert Nowaczyk and Prof. Helge Arz claims. A geomagnetic reversal is a change in the Earth's magnetic field such that the positions of magnetic north and magnetic south are interchanged. The Earth's field has alternated between periods of normal polarity, in which the direction of the field was the same as the present direction, and reverse polarity, in which the field was the opposite.
Magnetic studies of the GFZ German Research Centre for Geosciences on sediment cores from the Black Sea show that during this period, during the last ice age, a compass at the Black Sea would have pointed to the south instead of north.Moreover, data obtained by the research team formed around GFZ researchers Dr.
