Revised Essay on Regional Cold Anomalies by Dr. James Hansen, With New Graphs and Photos
The Earth has been in a period of rapid global warming for the past three decades. The assertion that the planet has entered a period of cooling in the past decade is without foundation. On the contrary, we find no significant deviation from the warming trend of the past three decades. Weather fluctuations exceed the magnitude of average global warming over the past half century. However, the perceptive person should be able to notice that climate is warming on decadal time scales. The global temperature trend over the past few decades has been strong enough that there is a noticeable “loading” of the climate dice that define the probability of unusually warm or cool seasons.
Where in the World is the Worst Place for Cold Weather?
The past year, 2009, tied as the second warmest year in the 130 years of global instrumental temperature records, in the surface temperature analysis of the NASA Goddard Institute for Space Studies (GISS). The Southern Hemisphere set a record as the warmest year for that half of the world.
Cleaning Up the Excess CO2
The other way to reduce the air’s excess CO2 is to unbalance the carbon cycle, typically by preventing some of the CO2 captured by photosynthesis from going back into the air when cells decompose. One has to stash dead biomass where the air can’t get to it. While sealed landfills help, it is only the ocean depths that would appear to have the capacity to draw down all of the CO2 that we have added since 1750.
Global Climatic Disruption Becoming More Evident
It’s easy for people in Russia, England and on the eastern coast of the US, with the severe winter conditions they’re experiencing, to forget that on other parts of our Planet are feeling the heat of dangerous climate change. What we should remember is that what we’re witnessing is not so much “Global Warming,” or even “Climate Change,” but “Global Climatic Disruption,” the term coined by President Obama’s chief science advisor John Holdren.
State of Climate Science: Videos of US Senate Select Committee Hearing
With the international climate change talks in Copenhagen fast approaching, there is real urgency to reach diplomatic consensus on a planetary solution. In a hearing hosted by Chairman Edward J. Markey on December 2, 2009, the US Senate Select Committee explored with climate scientists from the Obama administration, Dr. John Holdren and Dr. Jane Lubchenco, the urgent, consensus view on our planetary problem: that global warming is real, and the science indicates that it is getting worse.
“Hot Cities” from BBC World News – Entire Eight-Part Series
We highly recommend these powerful and informative videos of the documentary, Hot Cities, aired this fall on BBC World News TV. This is an excellent eight-part series about the present effects of global warming in cities around the world. If you haven’t caught these segments on television, you can watch them on your computer. Each runs about 45 minutes.
The effects of dangerous climate change are already happening, and people everywhere are finding ways of dealing with the changes this is causing in their lives. Witness the courage, tenacity and ingenuity of people suffering from disease, heat and lack of water, as well as high winds. You are certain to be amazed and inspired.
Tipping Point, After Tipping Point…
Another disturbing milestone was passed on November 6. The graph below shows that although extent of the Arctic sea ice this past summer was greater than that of 2007, it is now less, a record low for its date. Ice covered the Arctic Ocean in a smaller area on November 6, 2009 than in any other year on November 6 since observations began in 1979.
Australian Professor Writes of the Likelihood of Runaway Climate Change
Rather than decarbonising, the world is carbonising at an unprecedented rate, and it is doing so at precisely the time we know we have to stop it. 2.5 degrees Celsius is likely by the end of the century in spite of our childlike belief that climate change can be averted; the cost will prove incalculable.
Talks James Balog: Time-lapse proof of extreme ice loss
Photographer James Balog shares new image sequences from the Extreme Ice Survey, a network of time-lapse cameras recording glaciers receding at an alarming rate, some of the most vivid evidence yet of climate change.
Arctic at warmest levels in 2,000 years or more
Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years, new research indicates. The study, which incorporates geologic records and computer simulations, provides new evidence that the Arctic would be cooling if not for greenhouse gas emissions that are overpowering natural climate patterns.
