Collapse of desert bird populations likely due to heat stress from climate change

October 1, 2019 0 Comments Bird Flu Research, Birds, Climate, Environmental Awareness, Environmental Issues, Nature, Water, Zoology

Last year, biologists discovered that bird populations in the Mojave Desert had crashed over the past 100 years. The biologists now have evidence that heat stress is a key cause. Simulations with a computerized 'virtual bird' suggest that with higher temperatures, birds need more water to keep cool. Larger insectivores or carnivores should be most affected, and small seed-eaters less so if drinking water is available: just as the biologists reported last year.

Santa Barbara coastline: Preparing for the future

September 30, 2019 0 Comments Climate, Ecology, Ecosystems, Environmental Awareness, Environmental Issues, Environmental Policy, Global Warming, Oceanography

Santa Barbara County residents love their coastline, from the small-town beaches of Carpinteria to Santa Barbara's waterfront to camping hotspots like Jalama Beach and dramatic Guadalupe Dunes. But drastic changes are in store in coming decades as temperatures and sea levels rise, bringing massive impacts to local ecology and human systems.

An international research team has used nanoparticles to convert carbon dioxide into valuable raw materials. Scientists have adopted the principle from enzymes that produce complex molecules in multi-step reactions. The team transferred this mechanism to metallic nanoparticles, also known as nanozymes. The chemists used carbon dioxide to produce ethanol and propanol, which are common raw materials for the chemical industry.

Potentially large economic impacts of climate change can be avoided by human actions

September 25, 2019 0 Comments Climate, Environmental Awareness, Environmental Issues, Environmental Policies, Global Warming, Ocean Policy, Resource Shortage, World Development

A study estimates global-scale, multi-sectoral economic impacts of climate change, and suggests that a plausible range of decisions and actions by humans can determine the scale of the economic impacts, even if the uncertainty in the climate response to increased greenhouse gas concentration is considered. These actions include reductions of greenhouse gas emissions and improvement of socioeconomic conditions. This study highlights the importance of societal changes and the current generation's responsibility for the future.
