The Global Warming (GW) science as espoused by the UN Body IPCC (Intergovernmental Panel on Climate Change) is increasingly at odds with recent climate reality. The best available data sets reveal no significant warming of the earth’s climate since the new millennium, despite over 350 billion tons of human-CO2 emissions released in the earth’s environment in last 18 years or so. Further, cold weather extremes accompanied by heavy snow accumulation appear to be on the rise over North America, Europe and parts of Asia in last ten years or so; this is contrary to IPCC 2007 projection of warmer future climate with milder and shorter winters and decreasing snow accumulation worldwide. This talk will briefly overview the GW science and will discuss several uncertainties associated with the IPCC hypothesis of warming of the earth’s climate due to human-CO2 emissions. The talk will document uncertainty associated with climate models’ projections of future warming and discuss the role of large-scale atmospheric circulation patterns in determining mean temperature trends over various regions of the earth. The talk will focus on changes in extreme weather events and sea level rise in the context of present climate change debate and further discuss problems with switching to ‘Green Energy’ as alternative to fossil fuel. Several examples of recent cold weather extremes will be presented and the role of atmospheric CO2 vs sun’s variability on earth’s climate will be discussed with implications for future climate change in Canada and elsewhere.
Title: Assessing the Surface Urban Heat Island (SUHI) in Conakry using remote sensing and GIS technique
Arafan Traore got Master's degree in Bio-Systems Sustainability at the Graduate School of Agriculture Science, Hokkaido University in March, 2015. His research is about urbanization of the capital city of the Republic of Guinea and the impact of deforestation on sustainable agricultural development in the Republic of Guinea, the case of the prefecture of Faranah.
This study aimed to investigate the spatiotemporal variations in the surface urban heat island (SUHI) in the fast-growing urbanized city of Guinea (Conakry) and its surrounding rural area in order to characterize its effects on urban microclimate. The daytime and nighttime SUHI during the summer season (December to April) of the year 2018 was investigated based on the high temporal resolution of the Moderate Resolution Imaging Spectroradiometer (MODIS), product (MOD11A2) collectionV6. The analysis of the remote sensing data has revealed important urban and rural temperature differences. The daytime SUHI was most pronounced than the nighttime. During the daytime, the mean temperature difference between the most densely urbanized area and mixed vegetated rural area could have reached up to 6o C and that of the nighttime to 4o C respectively. Furthermore, this study has discussed that the diurnal variations of the SUHI were found to be different based on the land cover type, meteorological conditions and the geographical location of the city in relation to the sea, as land-see breeze circulations significantly affect the spatiotemporal variations of the SUHI especially at nighttime with the coastal area much warmer than the inland one. The results of this study will provide relevant information to urban planners and environmental managers for assessing and monitoring urban thermal environment, which is rapidly being altered by natural and anthropogenic influences.

Ecosystem are the drivers of community as well as nature in all. Urbanization has been altering ecosystems since last decade leading to changes in components of drivers. Neighborhood and colony level planning has been discussed and optimized in many researches and laws for betterment of ecological, Social and physical infrastructure. National and International guidelines are available for Single plot to ward level development in urban areas. But Knowledge or guidelines for combining ecosystems in urbanization is still far behind than pace of development. Apart from existing guidelines the situation in urban areas is deteriorating and environmental social and health related imbalances are piling up all over the world. IPCC and UNEP reports have been warning for changes in microclimate and macroclimate all over. The root cause is nothing but the initial lack in planning development at plot and neighborhood level. The guidelines present consider the development on basis of population, existing norms for distribution of land uses, roads, open spaces and heights of the building with allowable built up area. There is lack of strict rules for underground micro climatic conditions due to which development hamper the natural working system below the ground like natural drainages, aquifers, sub surface water flow and life below soil. The widened effects of these disturbances are seen in years with depleting water levels, diminishing capacities of wayer bodies, lakes and wells. Also the non availability of life creatures below soils affects the decompositions cycle again a warning for the disturbed air quality, solid waste and contaminated water etc.This paper studies in detail the disturbance of natural water cycle below soil with respect to prevailing rules and regulations for the colony level comparing the scenario with existing rules and with natural conditions or with aforesaid changes in new rules. The conclusions show and guide us depicting the need for updating and changes in existing rules for land uses, EIA and open spaces and extent of allowable built up with respect to soil characteristics, recharge and runoff before development and after development.

Air pollution costs Canada an estimated $36 billion in healthcare. A whale was recently discovered with 88 pounds of plastic in its stomach. Climate change is altering our ecological systems. Hearing statistics is one thing, but a Chinese proverb reminds us: “Tell me and I’ll forget; show me and I’ll remember; involve me and I’ll understand.” Committed to involving students, Green Schools Green Future (GSGF) stands behind the wisdom of Nelson Mandela: “Education is the most powerful weapon which you can use to change the world.” A not-for-profit organization founded in 2018 by environmentalist Nikole Bélanger, GSGF began with the dream of introducing a new, progressive and green education system in developing communities. Its mission involves teaching environmental and social responsibility. Its core curriculum includes not only key subjects, but vocational skills: coding, blockchain, and artificial intelligence. The school operates as a complete, sustainable cycle. By learning how to grow their own food through a vertical farm with an aquaponic system; by acquiring the knowledge behind the solar electricity that powers their laptops; and by absorbing values of community engagement, students will learn peaceful and powerful weapons to change the world. First inspired to build green schools when volunteering for Al Gore’s Climate Reality Project Canada in 2008, Nikole has since brought 28 volunteers together to support the project. The organization has already forged partnerships in Canada, Haiti, Sierra Leone and Gabon. Its goal is to build its first sustainable school pilot by the end of 2019

Title: An evaluation of environmental health threats associated with stream discharge from town Creek in Greenville, North Carolina
Jamil R. Blackmon is a Faculty of the Department of Health Education and Promotion, East Carolina University, USA. His research interest include Toxicology and Environment health.
Town Commons is a major recreational area within the city of Greenville that is frequented by many students and residents who utilize the water resources of the Tar River for kayaking, fishing and other activities. Complaints of gasoline odors and oily substances in Town Creek, near Town Commons have been documented since the 1980’s and these complaints persist today. Also, storm water runoff has been identified as major non-point source of pollution due to the high percentage of impervious surface (~50%) in the Town Creek Watershed. The North Carolina Department of Environmental and Natural Resources indicated that groundwater contaminated by leaking underground storage tanks (LUST) was likely discharging into Town Creek and causing the odor and aesthetic issues. Excess bacteria concentrations in the recreational waters, especially after rain events, may be a public and environmental health threat. The goal of this study was to determine if the discharge from Town Creek poses a threat to the environment and public health. The specific objectives included: 1) to determine if the benzene concentration in groundwater and surface water exceeded the national standards (51 µg/L); 2) to determine if the air quality standard for benzene was exceeded near Town Creek (5 ppm for 15 or more minutes); and 3) to determine if the concentrations of E. coli and enterococcus exceeded the recreational water quality standards (single sample threshold, 235 cfu/100 mL for E. coli and 61 cfu/100 mL for enterococcus). Results showed that benzene concentrations in water were higher than standards for 40% of the sampling events, benzene concentrations in the air were higher than standards 75% of the sampling events and E. coli concentration in the stream were higher than standards 40% of the time during base flow and 75% during storm flow. Implementation of storm water control measures, remediation of groundwater contaminated with benzene, and continued monitoring is suggested to improve the quality of water in Town Creek.
