Water: The Gift And The Curse: A Climate Change Preparedness Study On An Increased Rainfall Scenarios In The Yunguilla Cloud Forest, Ecuador, Emilia Dick Fiora Del Fabro

Independent Study Project (ISP) Collection

The purpose of this project was to try and better understand the risks posed to the Yunguilla community in an increased rainfall climate change scenario. While climate modeling is not exact, many models do predict increased rain and storm intensity in this area (“Explainer…”, 2018). This project studies erosion risk, and the potential damage to crops through a series of experiments and mapping.

The first experiment used three hydration percentages 50, 75 and 100, to water two crop types, Fragaria and Caspium, and monitored plant health to see the water's effect. The hydraulic stress testing did not model an increased …

Statement Of World Aquatic Scientific Societies On The Need To Take Urgent Action Against Human-Caused Climate Change, Based On Scientific Evidence [Dear Colleague Letter], Scott A. Bonar, Brian R. Murphy, Leanne H. Roulson, Jesse T. Trushenski, Douglas J. Austen, Michael Edward Douglas

United States Fish and Wildlife: Staff Publications

Dear Colleague Letter from the American Fisheries Society to fellow scientific societies, July 25, 2020, about the urgent need for responsive collective action to mitigate impending radical climate change. Includes the Statement of World Aquatic Scientific Societies on the Need to Take Urgent Action Against Human-Caused Climate Change, Based on Scientific Evidence, emphasizing the importance of aquatic ecosystems. Includes extensive citations and notes.

"Water is the most important natural resource on Earth as it is vital for life. Aquatic ecosystems, freshwater or marine, provide multiple benefits to human society, such as provisioning of oxygen, food, drinking water, genetic resources; regulation …

Kanjirowa Blues: An Exploration Of Environmental And Climate Consciousness In Lower Dolpa, Nepal, Casey Greenleaf

Independent Study Project (ISP) Collection

It has been scientifically demonstrated that high altitude, mountainous regions such as the Himalayas are extremely susceptible to and at accelerated risk of the effects of climate change. The regions of Lower Dolpa discussed in this work, Juphal, Dunai, Chun, and Dapu, lie in a glacial watershed, and are at present risk of landslides, floods, wildfires, and rely on agricultural and transhumant livelihoods that are uniquely susceptible to the impacts of changing temperature and weather patterns. People in this region are being forced to incrementally adapt and reframe their understanding of their surroundings due to both aforementioned severe events as …

Synergistic Use Of Remote Sensing And Modeling To Assess An Anomalously High Chlorophyll-A Event During Summer 2015 In The South Central Red Sea, Wenzhao Li, Hesham El-Askary, K. P. Manikandan, Mohamed A. Qurban, Michael J. Garay, Olga V. Kalishnikova

Mathematics, Physics, and Computer Science Faculty Articles and Research

An anomalously high chlorophyll-a (Chl-a) event (>2 mg/m3) during June 2015 in the South Central Red Sea (17.5° to 22°N, 37° to 42°E) was observed using Moderate Resolution Imaging Spectroradiometer (MODIS) data from the Terra and Aqua satellite platforms. This differs from the low Chl-a values (<0.5 mg/m3) usually encountered over the same region during summertime. To assess this anomaly and possible causes, we used a wide range of oceanographical and meteorological datasets, including Chl-a concentrations, sea surface temperature (SST), sea surface height (SSH), mixed layer depth (MLD), ocean current velocity and aerosol optical depth (AOD) obtained from different sensors and models. Findings confirmed this anomalous behavior in the spatial domain using Hovmöller data analysis techniques, while a time series analysis addressed monthly and daily variability. Our analysis suggests that a combination of factors controlling nutrient supply contributed to the anomalous phytoplankton growth. These factors include horizontal transfer of upwelling water through eddy circulation and possible mineral fertilization from atmospheric dust deposition. Coral reefs might have provided extra nutrient supply, yet this is out of the scope of our analysis. We thought that dust deposition from a coastal dust jet event in late June, coinciding with the phytoplankton blooms in the area under investigation, might have also contributed as shown by our AOD findings. However, a lag cross correlation showed a two- month lag between strong dust outbreak and the high Chl-a anomaly. The high Chl-a concentration at the edge of the eddy emphasizes the importance of horizontal advection in fertilizing oligotrophic (nutrient poor) Red Sea waters.

Perspectivas Culturais Na Comunicação Climática (Cultural Perspectives On Climate Communication), Karen E. Pennesi

Anthropology Publications

Este artigo considera que a previsão climática deve ser interpretada dentro de contextos sociais, culturais e linguísticos. Dentro de uma perspectiva antropológica baseada em entrevistas, observações e um questionário, será investigado como mudanças no meio-ambiente são entendidas por diferentes indivíduos, e transformadas em previsões que são comunicadas a diversos públicos. A linguagem utilizada e a maneira como a previsão é comunicada depende da experiência e dos objetivos do previsor, enquanto que a interpretação e a avaliação da previsão por outros são influenciadas por seus diferentes objetivos, atitudes, conhecimento e práticas. Esta etnografia da comunicação enfatiza o processo da comunicação das …

A Recommendation For An Enhanced Fujita Scale (Ef-Scale)

United States Department of Commerce: Staff Publications

Background

National Weather Service (NWS) personnel who are responsible for rating tornadoes have expressed frustrations in applying the Fujita Scale in a consistent and accurate manner. Weak links in a structural system or a slow-moving storm sometimes lead to an overrating of a tornado event. Several technical articles suggest that wind speeds associated with some descriptions of damage are too high. For example, a 260 mph wind speed is not required to completely destroy a well constructed house and blow away the debris. The damage occurs at significantly lower wind speeds. Minor et al. (1977) and Phan and Simiu (2003) …
