By Jacqueline Wen As the effects of climate change continue to escalate, their impacts seem especially noticeable and imminent for humans and other animals. But what about for forests and trees? In a study published in the Proceedings of the National Academy of Sciences (PNAS), Anna Trugman, an assistant professor in UCSB’s Department of Geography,
By Bob Yirka An international team of researchers has found that cyanobacteria (blue-green algae) produce the greenhouse gas methane. In their paper published in the journal Science Advances, the group describes tests they carried out with blue-green algae in their lab and what they found. Carbon dioxide is a greenhouse gas, and anthropogenic emissions are
By Guillaume Théroux-Rancourt et al. Abstract Maintaining high rates of photosynthesis in leaves requires efficient movement of CO2 from the atmosphere to the chloroplasts inside the leaf where it is converted into sugar. Throughout the evolution of vascular plants, CO2 diffusion across the leaf surface was maximized by reducing the sizes of the guard cells

By Roy Spencer, Ph.D. The increasing global ocean heat content (OHC) is often pointed to as the most quantitative way to monitor long-term changes in the global energy balance, which is believed to have been altered by anthropogenic greenhouse gas emissions. The challenge is that long-term temperature changes in the ocean below the top hundred
By Roy Spencer, Ph.D. The continuing global-average warmth over the last year has caused a few people to ask for my opinion regarding potential explanations. So, I updated the 1D energy budget model I described a couple years ago here with the most recent Multivariate ENSO Index (MEIv2) data. The model is initialized in the
By Kenneth Richard The current furor about an alleged connection between climate change, CO2 emissions, and Australian fires finds no support in the scientific literature. According to scientists, rising CO2 concentrations reduce fire ignition and burned area. Further, both global-scale and Australian fires were far more pervasive during the colder Little Ice Age. Here’s what
By Nicole Casal Moore A new artificial photosynthesis approach uses sunlight to turn carbon dioxide into methane, which could help make natural-gas-powered devices carbon neutral. Methane is the main component of natural gas. Photosynthesis is the process through which green plants use sunlight to make food for themselves out of carbon dioxide and water, releasing
By Howard Thomas Brady Between 1764 and 1767 William Hutchison, a mariner who was then Harbour Master at Liverpool in England, carefully recorded the times and heights of high tide at the Liverpool Old Dock. In the 19th Century the Mersey Docks and Harbour Board, that was to become the Liverpool Observatory, established state-of-the-art tidal
Gelatinous zooplankton makes an important contribution to marine carbon transport They are small, almost transparent, similar to jellyfish, and they occur in the ocean in huge quantities. Cnidaria, Ctenophora and Urochordata belong to the gelatinous plankton communities that are omnipresent in the ocean and are among the primary food sources for more highly developed marine
The CO2 Coalition was established in 2015 as a 501(c)(3) for the purpose of educating thought leaders, policy makers, and the public about the important contribution made by carbon dioxide to our lives and the economy.
@AOC Sorta how you took the #ExxonKnew comments out of context? https://t.co/xBjaDtdU4q
