A Woman’s Work…

The Governor’s Global Climate Summit ended with Oxfam America’s inaugural Sisters on the Planet Climate Leader Awards. Thanks to Karen Solomon at Opportunity Green, I was able to attend. The event showcased the work that women all over the world are doing to adapt to climate change. Sisters on the Planet is committed to exposing how livelihoods of the majority of the planet’s women are the most severely impacted by climate change. To quote the brochure:

“But if you remember one thing about Sisters on the Planet, make it this: Climate change is already having a disproportionate impact on poor people in the US and abroad, and it’s hitting women hardest.”

Oxfam is working with women all over the world to develop low-cost adaptation techniques relevant to the regions they’re in. Adapting to global warming requires a range of tactics, from helping families in flood-prone regions elevate their homes, build floating vegetable gardens, and store seeds and other necessities safely to helping farmers in drought-prone areas plant trees, drill wells and improve their irrigation techniques. Oxfam’s publication, Adaptation 101, shows the overall cost of some of these projects, and at what level they need to be carried out- in the community or nationally.

Even as the world prepares for the grand climate meet at Copenhagen this December, a large part of South India has gone under water. And while talks have already begun on coming up with an equitable deal and the very fear that there may be none, over 300 people have already lost their lives while millions are displaced and missing in this global warming related freak weather event, predicted well in advance by the IPCC in its Fourth Assessment Report in 2007.

Of the great apes–a group that includes chimps, gorillas, and bonobos–the orangutan (found only in the tropical rain forests of Sumatra and Borneo islands) is the most endangered, currently. Recent wild fires, tribal conflicts and on-going deforestation has seriously dwindled their total habitat. Some primatologists believe that the orangutan is the closest primate relative to humans–more than even the chimpanzee.

searocket plants (cakile maritima)

In another addition to the “secret life” (and mysterious abilities) of plants, a recent study demonstrated that a native, perennial plant, The Great Lakes Searocket (Cakile edentula), responds to the presence of related and non-related plants differently.

If the searocket is place in beds with plants that are not related to it, it will begin to stimulate its root system to grow more rapidly, which is a tactic that many plants use automatically in order to compete with others (for space, light, nutrients, etc.), indiscriminate of relatedness. But when placed in pots with related (sibling) plants, the searocket does not do this. Somehow–and no one has discovered how yet–the plant is able to detect similarities and differences (perhaps genetic, chemical, or physiological) in its local, vegetative environment. Many animals are not able to do this.

Scanning electron micrograph of Escherichia coli

Using two different model organisms–the E. coli bacterium and the single-celled yeast–scientist have begun unraveling a puzzling behavior of many micro-organisms: the ability to “predict” a change in environmental conditions.

It has been assumed for most of the history of micro-biological science that such micro-organisms are purely “reflexive”; they simply respond and adapt to external stimuli (such as exposure to chemicals, heat stress, or drugs). But research over he past 2 years by two different scientific teams (a Princeton team lead by Saeed Tavazoie, and, a team from the Weizmann Institute in Israel) is shaking up present understanding and over-turning basic assumptions.

“Worldwide, less than 8% of folks are responsible for 50% of emissions”, according to Professor Stephen Pacala of Princeton, co-author of Stabilization Wedges.

This group has a higher annual income than even the average American. But the US has the highest per-capita energy consumption rate of any nation, out-consuming the five most populated nations combined. Quite recent studies have confirmed what many already knew: that more affluent people consume more energy, and generate more green house gas (ghg) emissions. Thus, making significant cuts in ghg (to slow warming trends and mitigate climate change) without big cuts in this group’s ghg emissions is a major challenge.

The impact of greenhouse gases on global warming in the short term, and the possibility of severe climate change in the medium to long term, promise to create significant and lasting hardships for everyone. But these hardships will fall hardest on the world’s poorest, who are the ones least responsible for ghg-induced climate change.

It’s in the papers and on TV. It spreads across the Internet (including this very post), and it is finding its way into the classroom. Global climate change is nothing new. And it certainly isn’t going away. Not yet, anyway.

A report, “Global Climate Change Impacts in the United States,” was put out on June 16, 2009. The report compiles years of scientific research and takes into account new data not available during the preparation of previous assessments. It was produced by a consortium of experts from 13 U.S. government science agencies and from several major universities and research institutes.

The acidification of ocean habitats due to increased absorption of CO2 (which reacts with water to form carbonic acid) has become an issue of great concern over the past decade. Shellfish and other marine species (like corals and snails) that make their “homes” or shells from carbonates of calcium (CaCO3), are vulnerable to more acidic waters. A lower ph (generally below 8 on the ph scale) marine environment makes calcium ions less available to these creatures to fabricate their fortifications against nature’s predators and chemical forces. The result of this acidic exposure in shellfish is typically a much thinner shell, thus making the creature more susceptible to predation and even disease (as in the case of many corals; see: One Third of Reef-Building Corals Face Extinction Risk ).
