There is no tipping point. CO2 was present in much larger concentrations in the past and we are still here. This creates a disconnect between theory and reality that eliminates CO2 as the driver of modern climate change.
Carbon and nitrogen are essential elements that cycle through living organisms and the environment. The carbon cycle involves carbon dioxide being absorbed by plants through photosynthesis and released by animals through respiration. When plants can't absorb excess carbon produced, it builds up in the atmosphere and oceans, potentially causing global warming. The nitrogen cycle involves nitrogen gas in the air being "fixed" by bacteria living in plant root nodules or through lightning, making it usable for organisms. Both cycles involve constant movement of the elements through producers, consumers, decomposers and the environment.
A carbon footprint is a measure of the environmental impact of human activities through greenhouse gas emissions, with the average footprint being around 4,000 kg of carbon dioxide per person annually. The document provides information on calculating one's carbon footprint and discusses how as countries develop, their carbon footprints tend to decrease rather than increase, prompting the reader to consider ways to reduce their family's footprint through lifestyle changes and communicating concerns about climate change to politicians.
Carbon dioxide is a molecule composed of one carbon atom and two oxygen atoms. It is released through human activities like burning fossil fuels and is a major contributor to global warming. While carbon dioxide levels in the past were balanced by plants, rising levels due to human industry are now pushing concentrations higher than in the last 650,000 years. This disrupts the fragile balance of carbon dioxide and oxygen in the atmosphere and results in increased global warming.
This document discusses the abiotic cycles that recycle matter on Earth to sustain life, including the nitrogen cycle, water cycle, and carbon dioxide/oxygen cycle. These cycles move matter like nitrogen, water, carbon, and oxygen through ecosystems as plants, animals, and microbes break down waste and each other, and as atmospheric gases dissolve and circulate through environments. The recycling of matter through these natural cycles is essential to maintaining life on our planet.
The letter discusses how climate change is affecting the environment. It notes that temperatures are projected to rise between 0.5 to 8.6°F over the next hundred years according to the EPA. This warming will cause ice caps to melt and sea levels to rise, oceans to become more acidic which harms agriculture, and issues like droughts and floods in the US. The letter argues that agricultural practices that release methane from cows eating corn are disrupting the climate, and this methane and nitrous oxide from cow waste harm the environment more than carbon dioxide. It also discusses how rising carbon dioxide and ocean acidification damage coral reefs and marine biodiversity. The letter urges the recipient to be open-minded about climate change and
This document provides a chapter summary and 10 multiple choice test questions about cellular respiration. The questions cover topics like the purpose of respiration, the equations for aerobic and anaerobic respiration, the organisms that respire, the gas exchange surface in humans, the effect of carbon dioxide on an indicator solution, and processes that do and do not require energy from respiration. The document is designed to test understanding of key concepts about respiration.

This document discusses climate change and carbon dioxide levels. It notes that CO2 levels have risen steadily over several decades according to the Keeling Curve. Burning fossil fuels releases billions of tons of CO2 into the atmosphere each year from activities like driving gasoline-powered vehicles and coal combustion. Effects of rising temperatures include melting ice, rising sea levels, and species extinction. The 350.org movement aims to limit CO2 levels to 350 parts per million by 2100 through local events and actions that raise awareness of the target number. One such action discussed is an event on Buffalo Mountain to engage the community on addressing climate change through sustainable living.
Carbon, the way we view it, measure it, control it and price it has come to dominate debates of all kinds. So, what's it all about?
This is the starting point of a 'Carbon 101' guide released by The Climate Institute, alongside a podcast narration by Andrew Demetriou, CEO of the Australian Football League and Dr Graeme Pearman, former head of CSIRO Atmospheric Research. This presentation summarises the book and podcast. Both are available on The Climate Institute's website: www.climateinstitute.org.au/carbon-101.html
The document discusses carbon and climate change. It begins by explaining that carbon is essential to life but that human emissions of carbon dioxide and other greenhouse gases from the burning of fossil fuels are disrupting the natural carbon cycle and causing global warming. It notes that the atmospheric concentration of CO2 is now higher than at any time in the last 800,000 years. The document then discusses various carbon-related terms and concepts and explains why limiting global temperature rise to 2°C means that most fossil fuel reserves will need to remain unused. It concludes by discussing the need for countries like Australia to transition to a zero-carbon economy to remain competitive and prosperous in a carbon-constrained world.
How do we know the CO2 in the atmosphere is of anthropogenic origin-.docxcliftonl1
How do we know the CO2 in the atmosphere is of anthropogenic origin?
How do we know the CO2 in the atmosphere is of anthropogenic origin?
Solution
The co2 present in the atmosphere is obtained through the natural process like biogeochemical cycle such as carbon cycle..
Carbon cycle is nothing but the exchange of carbon between the oceans,rocks etc., and biosphere which includes plants and animals...plants absorb co2 present in atmosphere and undergo photosynthesis process to prepare carbohydrates.
Whereas these prepared carbohydrates are taken as food by the animals and human beings and these complex carbohydrates are converted into simple carbon compound nothing but co2 during respiration and while doing respiration releases energy into body inthe form of ATP and co2 into atmosphere..
According to carbon cycle the maximum amount of co2 present in atmosphere is anthropogenic origin.
The interesting thing is that recent days the atmospheric co2 level is significantly increasing because of human activities like burning of fossil fuels,increase in population,decrease in oxygen level in atmosphere etc.,
.
Carbon is the basis of life and one of the most common and studied elements. It can form millions of stable compounds due to its ability to form single, double, and triple bonds. Living organisms are the source of many carbon compounds, which is why organic chemistry is named after carbon-based life. The simplest organic compounds are hydrocarbons consisting of carbon and hydrogen, which play a role in fuels, lubricants, and plastics important to modern life.
The document discusses global warming and provides evidence that the Earth is warming due to human activity. It summarizes that the average global temperature has increased by 1 degree Fahrenheit over the past century, and that this warming is caused by increased greenhouse gas emissions from human use of fossil fuels. The document also lists several impacts of global warming, such as melting glaciers and sea ice, disrupted ecosystems, and more extreme weather events like hurricanes. Finally, it suggests individual actions people can take to reduce their carbon footprint and greenhouse gas emissions to help address the problem.
The document discusses several topics related to climate change, global warming, and the role of carbon dioxide (CO2) emissions. It questions whether climate change is real and human-caused, noting that the climate has always changed and the globe was once colder. It also questions the evidence and mechanisms proposed for dangerous anthropogenic (human-caused) global warming, including the amount of CO2 from human activities, the greenhouse effect, feedbacks from CO2 and water vapor, and whether models' predictions have been accurate.

Regrowing biomass to controal climate change Bru Pearce
Over the past 5000 years, human activity has reduced the total biomass on Earth to less than half of what existed in the prior 500,000 years. This 50% reduction in biomass has been largely overlooked in climate models, increasing our exposure to climate change while also pointing to restoring biomass as a solution. Restoring only around 15% of the lost biomass through reforestation and other means could pull enough carbon from the atmosphere to return carbon dioxide levels to around 280 ppm.
Anthropogenic Impact Cause, Effect and Cure Bru Pearce
Over the past 5000 years, human activity has reduced the total biomass on Earth to less than half of what it was in the preceding 500,000 years. This 50% reduction in biomass has major implications for climate change that have been overlooked in climate models. However, restoring just 15% of the lost biomass through large-scale reforestation and restoration efforts could pull enough carbon from the atmosphere to return carbon dioxide levels to pre-industrial levels of 280 ppm.
This document proposes that the university divest from fossil fuel companies in order to avoid profiting from climate change and to get ahead of an impending market crash as carbon release is limited. It argues that climate change is human-caused and occurring rapidly, posing threats to global water and food availability that could lead to widespread death and conflict. While acceptable climate change is limited to a temperature increase of 2 degrees Celsius, we have already warmed 0.8 degrees and known fossil fuel reserves far exceed the amount of carbon that can be released to stay below the 2 degree threshold. Therefore, divesting from the top 200 carbon reserve holding companies is recommended to ensure no financial support for breaking the climate.
The document discusses climate change and covers four main topics:
1) Climate science establishes that climate change is real and caused by human greenhouse gas emissions from burning fossil fuels. The level of scientific consensus is extremely high.
2) Climate impacts explains that the effects of climate change are already occurring, with global temperatures rising much faster than historical rates. Impacts include melting Arctic sea ice.
3) Climate solutions acknowledges that solutions exist to address climate change through reducing greenhouse gas emissions, though specifics are not discussed.
4) Climate politics questions why more action is not being taken given the severity of the problem and the existence of solutions. Moving forward will require global cooperation and a shift to more sustainable energy sources.
- The document discusses the greenhouse effect and how carbon dioxide and other gases in the atmosphere trap heat, warming the planet. It provides evidence that CO2 levels and global temperatures are increasing due to human activity like burning fossil fuels. While water vapor is a stronger greenhouse gas than CO2, increased CO2 levels are a concern because CO2 remains in the atmosphere for centuries. The summary concludes we should be concerned about rising CO2 and global warming.
1) The document discusses the growing threat of climate change, noting that CO2 levels are now at 391 ppm, the highest in 400,000 years, and temperatures are projected to rise 10 degrees as a result.
2) It provides examples of current climate change impacts like rising sea levels forcing evacuations and intensifying wildfires.
3) The document argues that solar energy can meet all global electricity demand and is the safest, cleanest renewable option available to mitigate climate change and build a safer future for generations to come.

Greenhouse Effect, Carbon Cycle & Rising TemperaturesSD Paul
The document discusses the greenhouse effect, carbon cycle, and rising global temperatures. It notes that scientists have debated whether temperature rise is natural or human-caused. The 2007 IPCC report concluded global warming is very likely due to human activities like fossil fuel use that emit greenhouse gases like carbon dioxide, disrupting the natural carbon cycle. The greenhouse effect occurs as certain gases trap infrared radiation emitted from the Earth's surface, and rising CO2 levels from activities such as deforestation and burning fossil fuels are enhancing the greenhouse effect.
The document discusses several topics related to global warming:
1. It argues that there is no single "normal" earth temperature and that temperatures have varied significantly over long periods in earth's history, with many periods being warmer than today.
2. It claims the earth has been cooling since 1998 according to satellite data, in contrast to IPCC predictions of steady warming.
3. It asserts there is no scientific consensus on anthropogenic global warming and cites several petitions and analyses that refute the claimed consensus.
4. It argues that CO2 is not a pollutant but rather a naturally occurring gas essential for life, and that levels have been much higher for most of earth's history without negative effects.
The carbon cycle describes the movement of carbon through Earth's biosphere, lithosphere, hydrosphere, and atmosphere. Carbon is exchanged between the atmosphere, living organisms, oceans, soil, rocks through various processes like photosynthesis, respiration, decomposition, combustion of fossil fuels and weathering of rocks. Human activities like burning fossil fuels and deforestation have increased atmospheric CO2 levels, impacting Earth's climate by enhancing the greenhouse effect.
Carbon is the fourth most abundant element and exists in compounds like CO2 that affect the planet. The carbon cycle transfers carbon between ecosystems on Earth. Humans disrupt this cycle by burning fossil fuels and releasing CO2, which causes global warming as it accumulates in the atmosphere and traps heat. Plants use CO2 in photosynthesis while animals use oxygen, and techniques like carbon sequestration aim to reduce CO2 levels.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
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.
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.
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.
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.
