Science: Three-megadalton complex of methanogenic electron-bifurcating and CO2-fixing enzymes
Methanogenic archaea use complex enzyme systems to survive in anoxic environments with limited energy. A key mechanism for energy conservation is electron bifurcation, a reaction that "splits" the energy of a pair of electrons, thus making one electron more reductive at the cost of the other. In a new study, researchers from the Max-Planck Institute for Terrestrial Microbiology and the ...

Where Has All the Ice Gone?
As the earth warms, glaciers and ice sheets are melting and seas are rising. Over the last century, the global average sea level rose by 17 centimeters (7 inches). This century, as waters warm and ice continues to melt, seas are projected to rise nearly 2 meters (6 feet), inundating coastal cities worldwide, such as New York, London, and Cairo. Melting sea ice, ice sheets, and mountain glaciers ...

How climate change impacts America’s energy infrastructure
As we’ve seen recently with Hurricane Sandy, epic drought, and wildfires, climate change visibly impacts lives and livelihoods throughout the United States. Global warming’s effects extend beyond people, wildlife, and ecosystems, though: They’re threatening America’s energy infrastructure. Today, I testified on this very subject before the Energy and Power Subcommittee of ...

What are the CO2 Emission Levels by Country?
Carbon dioxide emissions are one of the leading causes of climate change. It is generally perceived that to avoid the adverse effects of global warming. The world requires urgently decreasing the amount of carbon dioxide emitted into the atmosphere. In 2018, China was the biggest producer of carbon dioxide on the planet, with approximately 9.2 GT of CO2 emissions. This is around 28 per cent of ...

Greenhouse Gases List – Top 3 Global Warming Contributors
The following greenhouse gases list aims to shed some light on the main contributors to the global warming phenomenon. Although there are plenty of other contributing factors to global warming, Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), Water Vapour, and Ozone (O3) are the most popular. The greenhouse effect of these gases has been a long-standing cause of global warming, with some ...
