Warmer Seas Blocking Nature’s Carbon Pump

The researchers further warn that increasing temperatures in this vital, globally-extended ecosystem could “reduce the transfer of primary produced organic matter to higher trophic levels” (e.g., such as those that sustain corals and the many species that use them as habitat), interfere with the global carbon pump, and possibly set up a positive feedback mechanism, further increasing atmospheric carbon dioxide.

Ancient Rock Find Supports Early Date for First Photosynthetic Life

At some point in the geologic history of this planet, primitive, unicellular organisms (prokaryotes) emerged and proliferated. These primitive microbes were able to harness the Sun’s energy and convert it to food. The metabolic “waste product” of this photosynthetic (light-making) activity–Oxygen (O)–filled the Earth’s atmosphere over the course of vast time scales. This is sometimes referred to as the Great Oxidation Event (GOE). This geologically long event enabled the “explosion” of oxygen-breathing life forms in nearly every environment where [...]

Sea Slug Eats Algae and Becomes Plant-Like

After two weeks of a strict algae-only diet, a one-inch, green sea slug species (Elysia chlorotica) was somehow able to incorporate the plants chloroplasts (the cell-like organelles that trap solar energy and convert it to sugar), and then live out the rest of their single-year lives without eating.

40% of Amazon Will Disappear Despite Climate Change Efforts

Fourty percent or more of the Amazon rainforest will be “decimated” by the middle of the next century even if we cut all CO2 emissions by 2050, said the UK Met Office. The finding was presented this past month in Copenhagen, which is preparing to host the UN Climate Change Conference in December.

Radar Satellite image of rainforest in Rodonia, Brazil, 2000In this satellite image of deforestation in Brazil, tropical rainforest appears bright red, while pale red and brown areas represent cleared land. Black and gray areas have probably been recently burned.

Building on Mother Nature - Artificial Photosynthesis

Green plants, trees and their leaves remove noxious carbon dioxide from the air during a process known as Photosynthesis. This is why we are all so upset about the ruination of the rain forests, which act as natural air cleaners in volume due to the density of vegetation.

MIT Energy Storage Discovery Could Lead to ‘Unlimited’ Solar Power

Researchers at Massachusetts Institute of Technology (MIT) have discovered a new way of storing energy from sunlight that could lead to ‘unlimited’ solar power.

The process, loosely based on plant photosynthesis, uses solar energy to split water into hydrogen and oxygen gases. When needed, the gases can then be re-combined in a fuel cell, creating carbon-free electricity whether the sun is shining or not.

According to project leader Prof. Daniel Nocera, “This is the nirvana of what we’ve been talking about for years. Solar power has always been a limited, far-off solution. Now, we can seriously think about solar power as unlimited and soon.
