Global warming
Global warming is causing rapid climate change through rising CO2 emissions and other greenhouse gases from factors like deforestation, energy use, and industrialization. This is raising global temperatures and melting ice caps, glaciers, and permafrost. Consequences include rising sea levels that could flood coastal cities, stronger storms, droughts, and species extinction as animals' habitats change. Immediate action is urgently needed to reduce greenhouse gas emissions and mitigate the effects of climate change.
Global Warming: It's Worse Than We Thought
The document discusses the impacts of global warming that have been more severe than originally predicted by scientists. Key points include:
- Scientists have consistently underestimated the effects of climate change in their early estimates. Measured impacts have often exceeded original predictions.
- Effects like sea level rise and temperature increases will persist for at least 1,000 years even if carbon emissions are reduced due to feedback loops and tipping points in the climate system.
- Failure to significantly reduce carbon emissions by 2018 could lead to a 3 degree Celsius rise in average temperatures worldwide, with devastating consequences including widespread drought and desertification.

20091121 Globalwarming Sw Group02
The document discusses several environmental problems related to rising global temperatures and ocean pollution. It notes that world leaders at the upcoming Copenhagen Climate Conference may fail to reach a binding agreement to replace the Kyoto Protocol. Additionally, there has been little discussion of protecting oceans and seas from overfishing and pollution. The document also outlines geographical problems like droughts and melting Arctic ice that threaten to raise sea levels and force coastal populations to relocate. Rising seas would further exacerbate social problems like lack of access to clean water.
Global Warming
The document discusses evidence that global warming is occurring, including rising average temperatures around the world since 1800 and the hottest decades being the last two of the 20th century. It notes that humans are releasing carbon dioxide faster than nature can absorb it. The effects of global warming described include melting glaciers causing sea level rise and changes to animal habitats and behaviors like hibernation patterns being disrupted. Solutions proposed include developing renewable energy and clean coal technologies as well as international cooperation on reducing carbon emissions.
Case Study Examples Climate The Environment And People
Hurricane Mitch formed over the Caribbean Sea in 1998 due to very low pressure and warm sea surface temperatures. It caused catastrophic flooding and landslides in Honduras and Nicaragua from over 1800 mm of rain, killing over 11,000 people. The hurricane destroyed 70% of Honduras' banana crop and over 30% of Nicaragua's coffee crop, causing major economic damage and unemployment. Over $280 million in international aid was provided to help rebuild homes, shelters, and infrastructure.

Jagan global warming
Global warming is caused by both natural factors and human activities that increase greenhouse gas emissions like carbon dioxide. The key human factors are burning fossil fuels and deforestation. This traps heat in the lower atmosphere and causes average surface temperatures to rise globally. Effects of global warming include rising sea levels, more extreme weather, damage to ecosystems, and threats to food and water security. Addressing climate change requires both mitigation efforts like transitioning to renewable energy and adaptation strategies to deal with impacts that can no longer be avoided.
Arctic
The Arctic region lies within the Arctic Circle and includes parts of 8 countries. It has a very cold climate, with average January temperatures of -35°C. The indigenous Inuit people have lived in the area for over 9,000 years, traditionally hunting and fishing, but many now work in oil fields. The Arctic ice is melting rapidly due to climate change, with a loss of 14% of permanent sea ice from 2004-2005. As ice melts, it is replaced by darker water that absorbs more solar radiation, causing a feedback loop of more melting. By 2100, 50-60% of Arctic ice may be gone, and by 2700 it could all be melted. This endangers marine species and indigenous communities
Global warming by khadar
Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.
Climate change
The document discusses various topics related to climate change including:
1. Different biomes and their typical climates such as tundra, taiga, temperate grasslands, and tropical rainforests.
2. Causes of climate change like the greenhouse effect, El Nino, and greenhouse gases such as carbon dioxide, methane, and nitrous oxide.
3. Impacts of climate change like rising sea levels, more frequent extreme weather events, threats to agriculture and water supplies, and effects on plants and animals.
4. Examples of climate change impacts through case studies on drought in Australia and Hurricane Katrina in New Orleans.
Global Warming
Global warming is caused by increased levels of carbon dioxide and other greenhouse gases in the atmosphere from human activities like burning fossil fuels and deforestation. This is causing the average surface temperature of the Earth to rise, leading to changes in climate with serious environmental and socioeconomic consequences. Some of these consequences include rising sea levels, stronger hurricanes, more severe droughts and heat waves, melting Arctic sea ice and glaciers, range changes and population declines in animal species, and increased spread of diseases. If warming continues unabated and the polar ice caps melt completely, it could further increase temperatures in a feedback loop and disrupt ocean currents that regulate climate.
Lesson5impacts climate and change Edexcel Geography GCSE B
The document discusses the potential impacts of climate change around the world and in specific regions. Some key impacts that could occur globally include increased risks of food insecurity, water scarcity, and extreme weather events. Developing nations are expected to face greater challenges in adapting to climate change impacts. Specific regions may experience threats such as sea level rise endangering coastal communities, shifts in agricultural production, increased disease prevalence, and disruptions to water supplies from glacier melting. Bangladesh is highlighted as one country particularly vulnerable to climate change due to its low-lying geography and population density.
Lesson5impacts
The document discusses potential global impacts of climate change. It predicts that agriculture and poverty will be heavily affected as extreme weather increases. Water scarcity is also expected to rise due to melting glaciers and rising sea levels. Specific impacts are predicted for regions around the world, including increased flooding in coastal areas, changes in agricultural production, and threats to infrastructure and habitats.

The Ocean and Cryosphere in a Changing Climate
The document summarizes key findings from the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate. It finds that the ocean and cryosphere have absorbed much of the increased heat from climate change, with consequences including sea level rise, shrinking glaciers and ice sheets, and changes in marine life. These changes threaten coastal communities, water resources, and cultural heritage. Urgent action is needed to address these impacts and transition societies in a sustainable way. Limiting warming to 1.5C would help societies better adapt to inevitable changes.

Antarctica by Chloe
Antarctica has no permanent human residents but is used for scientific research. Global warming is having serious effects on Antarctica such as melting ice shelves and decreasing populations of penguins and krill. The melting ice caps and rising sea levels caused by climate change in Antarctica threaten coastal lands and could lead to food shortages and natural disasters around the world.
Drought Report
The document discusses droughts, including their causes, effects, and responses. It provides examples of droughts in Kenya in 2004 and Australia from 2000-2006. Drought is caused by a lack of precipitation over an extended period, resulting in serious water imbalance. Common causes include high pressure systems, air mass patterns, and climate change factors like El Nino. Droughts can cause food and water shortages for people and livestock, economic impacts from reduced agriculture and tourism, and the need for conservation efforts, aid, and policy responses. Planning for future droughts is important to mitigate their effects.

Chapter 5 natural environment
The natural environment chapter discusses the natural environment of various regions including Southeast Asia, East Asia, Europe, and North America. It defines the natural environment and discusses components like climate, vegetation, wildlife, and natural hazards specific to each region. Some key environmental problems discussed are natural disasters like tsunamis, diseases prevalent in different areas, and types of pollution including thermal and haze pollution. It also provides details on climate types such as tropical, equatorial, oceanic, continental, and Mediterranean climates.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
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.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

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.

Climate Change All over the World .pptx
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

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.
