The document discusses the global carbon cycle, which describes the movement of carbon between different reservoirs in the Earth system. It notes that natural processes like photosynthesis and respiration move carbon between the atmosphere and biosphere. However, human activities are also impacting the carbon cycle by adding additional CO2 to the atmosphere through processes like burning fossil fuels. The carbon cycle can be divided into shorter term biological/physical processes and longer term geological processes that operate over millions of years.

Carbon cycle and global concerns on environment
Carbon is the primary building block of life and cycles through different carbon pools in the biosphere, lithosphere, hydrosphere, and atmosphere. The global carbon cycle involves fluxes of carbon between these pools through natural processes like photosynthesis, respiration, and geological processes. However, human activities like burning fossil fuels and deforestation have significantly increased carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle and causing global climate change. Rising global temperatures will lead to problems like rising sea levels, food shortages, and threats to biodiversity.
Energy Balance
This document discusses how energy from the sun interacts with the atmosphere and Earth's surface. Solar radiation enters the atmosphere and is scattered, refracted, reflected, or absorbed. Atmospheric gases and particles influence these processes. Absorbed radiation is transferred within the atmosphere and at the surface via conduction, convection, and radiation. Greenhouse gases in the atmosphere and clouds contribute to the greenhouse effect by trapping infrared radiation emitted from the surface. The surface and atmospheric energy budgets describe the distribution of solar energy after it passes through the atmosphere and reaches the Earth's surface.

Structure of atmosphere
The atmosphere is composed of several distinct layers. The innermost layer is the troposphere, which extends from the Earth's surface to around 17 km high at the equator. It contains around 75% of the atmosphere's mass. Above the troposphere is the stratosphere, which extends from 17-48 km high. It contains higher levels of ozone which absorbs over 99% of the sun's harmful UV radiation. The stratosphere is followed by the mesosphere and thermosphere, with temperatures decreasing and then increasing with altitude.

Soil profile
Soil is a vital part of the natural environment and is made up of mineral material, organic material, air, and water. The soil profile consists of horizontal layers called horizons that vary in thickness, structure, consistency, porosity, acidity, and composition. The major horizons from top to bottom are O (organic matter), A (topsoil), E (leaching layer), B (subsoil), C (saprolite), and R (bedrock). Soil structure is determined by the combination of primary particles like sand, silt, and clay, while soil composition includes approximately 45% minerals and nutrients, 5% organic matter, 25% water, and 25% air.
Greenhouse Gases and Global Warming
Water vapor, carbon dioxide, and methane are greenhouse gases that absorb infrared radiation emitted from the Earth's surface and atmosphere. While water vapor accounts for the largest percentage of infrared absorption, rising levels of carbon dioxide and methane from human activities like burning fossil fuels are contributing most to increased global temperatures. The speed of current climate change caused by greenhouse gas emissions is unprecedented and poses serious risks to ecosystems if average temperatures rise more than 3 degrees Celsius.
Biogeochemical cycles
The document summarizes several major biogeochemical cycles - carbon, nitrogen, phosphorus, and sulfur. It describes the reservoirs, fluxes, and transformations involved in each cycle, which are driven by biological and geological processes. Microbial activity plays an important role in facilitating exchanges between different reservoirs like the atmosphere, biosphere, hydrosphere and lithosphere. The carbon, nitrogen and sulfur cycles involve gaseous forms that are exchanged between air and oceans/land. Phosphorus lacks a gaseous phase and its cycle is more sedimentary in nature.

Atmospheric Pollution
This is a PPT on Atmospheric Pollution. Here it decribes the 3 main types of Atmospheric Pollution: 1.Acid Rain, 2.Ozone Depletion, 3.Green House Effect.
Section 01
Soil is formed through the interaction of the lithosphere, atmosphere, hydrosphere, and biosphere. It is the biologically active, porous medium that develops below the land surface. Soil consists of mineral and organic components, with pore spaces filled with either air or water. As the interface between these spheres, soil impacts ecosystem dynamics and the Earth system as a whole. It is classified based on its horizons, which form layers with different properties over time through soil-forming factors like climate, organisms, relief, and parent material.
Composition and Structure of Atmosphere
The document summarizes the composition and structure of the atmosphere. It is composed of several layers:
1) The troposphere, closest to Earth's surface and containing 75% of the atmosphere's mass. Temperature decreases with altitude.
2) The stratosphere above the troposphere, containing the ozone layer which absorbs UV radiation. Temperature increases with altitude here.
3) The mesosphere where temperature decreases with altitude again.
4) The thermosphere, growing very hot due to solar activity.
5) The exosphere, the uppermost layer where molecules can escape into space.
Energy budget of earth
Earth's energy budget refers to the tracking of how much energy is flowing into and out of the Earth's climate, where the energy is going, and if the energy coming in balances with the energy going out. The Earth receives energy from the Sun, and it also reflects and radiates energy back into space. All of the energy that warms the atmosphere, oceans and land must be radiated back into space in order to maintain our current climate. If the amount of energy radiating back into space is decreased by even a very small amount, it can lead to warming. It is believed that increasing levels of carbon dioxide in the atmosphere has a 'greenhouse effect' of reducing the amount of energy radiated into space.

Insolation and heat budget
The solar radiation that reaches Earth is the primary energy source that drives atmospheric and oceanic circulation systems and the hydrologic cycle. Most of the radiation emitted from the sun is in the visible spectrum. While some solar radiation is reflected or scattered by gases, particles, and surfaces like clouds, ice, and snow, most is absorbed by Earth and its atmosphere. This absorbed solar energy is then re-radiated as terrestrial radiation and helps maintain the planet's heat balance.
Environmental chemistry
This document provides an overview of environmental chemistry. It begins by defining environmental chemistry and describing the key environmental segments of the biosphere, atmosphere, hydrosphere, and lithosphere. It then discusses environmental quality standards, indicators of pollution including dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, and total dissolved solids. The document outlines the scope of environmental chemistry and notes the need for public awareness of environmental issues.
Acid Rain
Acid rain is rain with a pH lower than 5 that is caused by sulfur and nitrogen oxides combining with water from the atmosphere. These acid anhydrides are emitted primarily from coal burning power plants and automobile exhaust, and can accelerate structure decay, hinder plant growth, and damage aquatic ecosystems. The Clean Air Act and technologies like catalytic converters and scrubbers have helped reduce acid rain by legislating emission standards and encouraging cleaner energy use.
Greenhouse gases and their effect
This document discusses the composition of the Earth's atmosphere and greenhouse gases. It notes that while nitrogen and oxygen make up most of the atmosphere, trace gases like water vapor, carbon dioxide, methane and nitrous oxide have an outsized influence on climate. These greenhouse gases absorb and emit thermal radiation and warm the atmosphere, comprising what is known as the greenhouse effect. The document also outlines the sources and sinks of various greenhouse gases as well as their impacts on climate change like rising global temperatures and sea levels.
Nutrient cycling
1. The document discusses nutrient cycles in ecosystems, focusing on carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur cycles.
2. Key processes mentioned include photosynthesis and respiration (carbon cycle), nitrogen fixation and denitrification (nitrogen cycle), rock weathering (phosphorus cycle), and the roles of various bacteria in transforming sulfur compounds (sulfur cycle).
3. Nutrient cycles involve the movement of elements between living organisms, soil, atmosphere, and water through biological and geological processes.
Biogeochemical cycles
Biogeochemical cycles describe the cycling of essential nutrients like carbon, oxygen, nitrogen, phosphorus, and sulfur between the biotic (living) and abiotic (non-living) components of ecosystems. Energy from the sun drives these cycles as nutrients are exchanged between organisms, water, air, soil, and rock. Humans have disrupted natural biogeochemical cycles through activities like burning fossil fuels, clearing vegetation, using fertilizers, and pollution, which has contributed to issues like climate change and algal blooms.

Green house effect
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat to make the earth surface warmer leading to global warming.
Global warming and Green house effect
The document discusses several topics related to greenhouse gases and global warming:
1) It explains what the greenhouse effect and global warming are, how greenhouse gases like carbon dioxide trap heat in the atmosphere and cause the planet to warm up over time.
2) It then covers the causes of global warming like greenhouse gas emissions from burning fossil fuels, deforestation, and industrial pollution, as well as consequences like climate change, rising sea levels, and endangered species.
3) Finally, it discusses solutions that can help mitigate global warming such as afforestation, transitioning to renewable energy, and reducing greenhouse gas emissions through conservation efforts.
An introduction to soils, soil formation and terminology
The document provides an introduction to soils and soil terminology. It defines soil and discusses soil formation factors such as parent material, climate, organisms, relief, and time. It also examines soil processes like weathering, decomposition, humification, capillary action, leaching, and translocation. Key terms are explained, like soil horizons, soil texture, and different types of humus. Soil features including color, structure, and drainage properties are also covered.
Ozone depletion
The document discusses ozone depletion in the stratosphere. It notes that a thin layer of ozone in the stratosphere protects the Earth from harmful UV radiation. The concentration of ozone is highest at mid-latitudes in the stratosphere. The document then explains that chlorofluorocarbons (CFCs) released into the atmosphere can travel to the stratosphere and destroy ozone molecules. It highlights that annual ozone depletion over Antarctica reaches up to 70% due to chemical reactions on polar stratospheric clouds that release chlorine. The 1991 eruption of Mount Pinatubo increased mid-latitude ozone depletion by injecting sulfur into the stratosphere. International agreements aim to phase out CFC production but developing nations
Greenhouse effect
This document discusses the greenhouse effect and global warming. It explains that greenhouse gases like carbon dioxide, methane, nitrous oxide and chlorofluorocarbons in the atmosphere trap heat from the sun similarly to how glass traps heat in a greenhouse. Increased levels of these gases are causing global warming and climate change impacts like rising sea levels, more extreme weather, and disruptions to ecosystems and agriculture. The document outlines the major greenhouse gases and their absorption ranges, as well as current and projected impacts of climate change.
Atmospheric aerosols and air pollution, ozone
The document discusses aerosols and their effects. It provides information on:
1. What aerosols are, including their natural and anthropogenic sources. Aerosols can affect climate directly by scattering and absorbing radiation, and indirectly by altering cloud properties.
2. The health impacts of aerosols, as they are a major component of smog. Epidemiological studies have shown correlations between elevated aerosol levels and increased mortality, hospital visits, and excess infant mortality.
3. The effects of black carbon aerosols specifically. Black carbon warms the atmosphere through absorption of sunlight and contributes to melting of snow and ice when deposited on their surfaces. It may be responsible for up to 40

Global Carbon Cycle And Global Change
The document discusses how humans have altered the global carbon cycle through burning fossil fuels, deforestation, and burning trees. Burning fossil fuels increases the rate of carbon moving from rocks to the atmosphere. Deforestation and burning trees decreases the rate of carbon moving from the atmosphere to living organisms. This has increased the level of carbon dioxide in the atmosphere, which is a greenhouse gas that absorbs and reradiates infrared radiation, contributing to global climate change. The Mauna Loa curve shows increasing carbon dioxide levels in the atmosphere since the 1950s.
Carbon cycle
The document discusses the carbon cycle, which involves carbon continually moving through living organisms, oceans, atmosphere, and rocks. There are four main subcycles - the rock subcycle over millions of years, ocean subcycle over hundreds of years, biological subcycle over days to years, and fossil fuel subcycle over millions of years being released in recent decades. Carbon is essential for life and plays a key role in climate as a greenhouse gas.
Carbon Cycle
The document summarizes the carbon cycle, which is the movement of carbon between different reservoirs on Earth and in its atmosphere. Carbon continually cycles between living organisms, oceans, atmosphere, and rocks through various processes over timescales ranging from years to millions of years. Key parts of the cycle include photosynthesis fixing carbon from the atmosphere into organisms, respiration and decomposition releasing carbon back to the air, and geological processes like weathering sequestering carbon in rocks over millions of years.

Biogeochemical cycle
Biogeochemical cycles describe the movement of essential chemical elements on Earth between living and nonliving components. Elements cycle through different reservoirs, with some cycling through the atmosphere (gas cycles for carbon, nitrogen, oxygen) and others cycling through sediments on land and in oceans (sedimentary cycles for phosphorus, sulfur). These cycles are crucial for sustaining life as they recycle nutrients consumed by living organisms. Human activities can disrupt biogeochemical cycles, threatening ecosystems.
FinalPaperTemplate
This document describes a model of the carbon cycle and its modification to account for human activities like fossil fuel combustion and deforestation. The model includes five reservoirs - atmosphere, terrestrial biosphere, ocean surface, deep ocean, and soil. Differential equations describe the natural flows between reservoirs. The modified model adds a fossil fuel reservoir and changes flows to represent human impacts. Running the model for 500 years shows increases in atmospheric and soil carbon and a corresponding rise in global temperature of around 3.5 degrees Celsius due primarily to increased CO2 levels.

intake and output of carbon is a component of all plant and animal life.
The carbon cycle is vital to life on Earth. Nature tends to keep carbon levels balanced,
meaning that the amount of carbon naturally released from reservoirs is equal to the
amount that is naturally absorbed by reservoirs. Maintaining this carbon balance
allows the planet to remain hospitable for life. Scientists believe that humans have
upset this balance by burning fossil fuels, which has added more carbon to
the atmosphere than usual and led to climate change and global warming.Carbon cycle
The document discusses biogeochemical cycles and focuses on the carbon cycle. It defines biogeochemical cycles as pathways that move chemical substances through biotic and abiotic parts of Earth. It describes the carbon cycle, noting that carbon is recycled through photosynthesis, respiration, and the decomposition of organic matter, moving between the atmosphere, organisms, oceans, soils, and fossil fuels. It explains how human activities like burning fossil fuels and deforestation are disrupting the carbon cycle and leading to issues like global warming.
Climate change
Carbon capture and storage (CCS) aims to mitigate climate change by capturing carbon dioxide from large emission sources like power plants and storing it underground instead of releasing it into the atmosphere. While CO2 capture technology is commercially available, storage is less developed - no power plants currently operate with full CCS. CCS involves capturing CO2 through biological, chemical, or physical processes, and then transporting it via pipeline or ship for storage in geological formations like saline aquifers or depleted oil fields. The Delhi Metro has helped reduce air pollution and earned carbon credits by providing a non-polluting public transit alternative that has shifted travelers away from more emissions-intensive private vehicles.
Greenhouse Effect, Carbon Cycle & Rising Temperatures
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.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
