How varying climate conditions impact vulnerable species
Biologists analyzed tooth breakage and wear - both gross and micro - of Arctic foxes from Russia's Yamal Peninsula and found that varying climate conditions in the Arctic affect the animals that live there.

Not just CO2: Rising temperatures also alter photosynthesis in a changing climate
Agricultural scientists who study climate change often focus on how increasing atmospheric carbon dioxide levels will affect crop yields. But rising temperatures are likely to complicate the picture, researchers report in a new review of the topic.

Excessive heat can reduce the efficiency of enzymes that drive photosynthesis and can hinder plants' ability to regulate CO2 uptake and water loss, the researchers write. Structural features can make plants more -- or less -- susceptible to heat stress. Ecosystem attributes -- such as the size and density of plants, the arrangement of leaves on plants or local atmospheric conditions -- also influence how heat will affect crop yields.

Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.
