Climate change is defined as long-term shifts in weather patterns over decades or longer. It is caused by both natural factors like ocean currents and human factors like burning fossil fuels. Effects of climate change include rising sea levels as glaciers and ice caps melt, more severe weather events, and harm to ecosystems. Global warming is a specific result of climate change where the average temperature of the Earth's atmosphere and oceans increase due to greenhouse gas emissions. Deforestation exacerbates global warming by reducing carbon absorption and increasing greenhouse gases in the atmosphere. Continued climate change will have widespread environmental, social, and economic impacts.
Global warming refers to the ongoing rise in average surface temperatures of both land and sea. Since 1971, 90% of the additional heat has been absorbed by oceans. While the term commonly refers to air temperature increases, it also encompasses rising sea surface temperatures. The document then lists several actions individuals can take to help reduce their carbon footprint, such as reducing waste, recycling, planting trees, and taking public transportation. It concludes by arguing that caution is warranted given the potential catastrophic impacts of climate change on humanity.
Climate change refers to changes in global or regional climate patterns attributed largely to the increased levels of atmospheric carbon dioxide produced by human use of fossil fuels. The impacts of climate change include more extreme drought, rising sea levels, melting glaciers, and more frequent natural disasters like hurricanes, floods and wildfires. Actions that can be taken to address climate change involve reducing carbon emissions through use of renewable energy, electrified transportation, energy efficiency and combating deforestation.
Climate change refers to changes in long-term weather patterns caused by global warming. It can include changes in temperature, precipitation levels, and more extreme weather events. The Earth is currently warming at a rapid pace, with the 10 warmest years on record all occurring since 1997. This warming is causing sea levels to rise, sea ice to melt, and precipitation patterns to change. Many plants and animals are struggling to adapt to these effects of climate change. While some solutions for addressing climate change have been proposed, such as transitioning away from fossil fuels and upgrading infrastructure, there is still a lack of agreement among world leaders on how to effectively tackle this global issue.
1. Climate change refers to substantial changes in weather patterns due to human activities that release greenhouse gases into the atmosphere.
2. The earth has warmed over 0.5°C in the last century and models predict further warming of 1.8-4.0°C by 2100, with rising sea levels and more extreme weather.
3. Human activities like burning fossil fuels and deforestation are the main causes of increasing greenhouse gas emissions like carbon dioxide in the atmosphere.
Climate change refers to seasonal changes over a long period of time.
Worldwide, people are paying serious attention to climate change.
Because so many systems are tied to climate, such as, people, plants and animals live, such as food production, availability and use of water, and health risks.
A carbon footprint is a measure of the greenhouse gases produced through human activities, such as the use of electricity, transportation, and production of goods. It is quantified as the amount of carbon dioxide and other greenhouse gases emitted. An individual, organization, or nation's carbon footprint can be calculated through a greenhouse gas emissions assessment. Strategies to reduce carbon footprints include technological advances, process improvements, carbon offsetting projects, and decreasing energy usage or reliance on carbon-intensive fuels.

Global warming is causing significant changes to the Earth's climate. Glaciers and ice sheets are melting, sea levels are rising, and extreme weather events are becoming more common. The scientific consensus is that human activities, such as burning fossil fuels and deforestation, have increased greenhouse gas levels and caused most of the warming observed since the mid-20th century. As temperatures continue to rise, the impacts on the environment, plants and animals, weather patterns, and human society will intensify and become more costly. Individual actions to reduce energy use and greenhouse gas emissions can help address the problem.
This document defines climate change as a change directly or indirectly caused by human activity that alters the composition of the atmosphere in addition to natural variability. It lists both natural causes like volcanic eruptions and human causes such as greenhouse gas emissions, deforestation, and burning fossil fuels as contributing to climate change. The effects of climate change discussed include rising sea levels from melting ice sheets, more extreme weather events like heavy rainfall and drought, declining crop productivity, changing ecosystems, rising temperatures, and ocean acidification.
This document discusses carbon footprints and greenhouse gas emissions. It defines a carbon footprint as the total amount of carbon dioxide and other greenhouse gases emitted over the course of a product's life cycle, from raw material extraction to end-of-life disposal. It explains the three scopes of carbon footprints and provides examples of activities and their associated emissions. The document emphasizes reducing carbon footprints through alternatives like renewable energy, recycling, and more sustainable consumption habits.
Global climate change is caused by increased greenhouse gases trapping heat in the atmosphere. The average global temperature has increased 0.76°C from 1850-2005, and the rate of warming over the past 50 years is nearly double that of the past 100 years. If greenhouse gas emissions are not reduced, atmospheric levels could increase to between 1.003-1.009, raising global temperatures up to 10°C higher than normal. Developing countries will face disproportionate effects including changes to agriculture, water resources, and human health that could worsen issues like poverty, disease, and conflict. Investment in climate-resilient crops and other adaptation measures can help address food insecurity.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
