Global warming
Global warming is real and caused by greenhouse gases like carbon dioxide and methane that trap heat in the atmosphere. We know the planet is warming from temperature records and satellite images that show rising temperatures over the past century. While global warming cannot be stopped immediately due to natural delays, actions like using less energy, driving less, and developing renewable energy can help slow the rate of warming and reduce its impacts.
Green House Effect[1]
The document discusses the greenhouse effect and how it works. Greenhouse gases like carbon dioxide and methane act as insulators, trapping some heat in the atmosphere. Over time, increased greenhouse gas emissions, especially carbon dioxide, have thickened this layer and trapped more heat. The natural greenhouse effect is now excessive due to immense increases in carbon dioxide and other greenhouse gas emissions. This is correlated with effects like increased sea levels and global warming that impact coastal cities.

Concept map
This document discusses global warming and its causes and effects. It states that carbon dioxide emissions cause global warming, leading to problems like droughts, floods, melting ice caps, rising sea temperatures and sea levels, and stronger hurricanes and tornadoes. The document suggests using public transport, efficient energy use, recycling, and reducing our carbon footprint to help prevent the problems caused by global warming.
Weather11
The document discusses climate change versus weather, how climate change is causing changes in weather patterns like stronger hurricanes and more wildfires. It explains that the global climate is getting warmer due to the greenhouse effect and provides examples like less snow and more extreme weather events. It discusses how both carbon and water vapor contribute to climate change as greenhouse gases. Changing climate impacts various species and also affects weather patterns, hurricanes, and human events like the Winter Olympics. Global cooling is defined as when the climate cools down and the Earth heads towards another ice age.
Tori Cleo 4
The document defines greenhouse effect, climate change, and global warming. There is a relationship between the three where the greenhouse effect traps heat causing climate change and global warming. Global warming is caused by increased greenhouse gases from human activities like burning fossil fuels. Consequences of unchecked global warming include rising sea levels, stronger hurricanes, and disrupted ecosystems. While some argue global warming is natural, the authors believe humans have exacerbated it through greenhouse gas emissions and more must be done to reverse impacts. Ways to fight global warming include using less energy and planting trees.

The document discusses the causes and effects of global warming such as greenhouse gases, CO2 emissions, and overpopulation contributing to rising global temperatures. This leads to problems like increased water and food demand, floods, droughts, and sea level changes. Some solutions proposed include using renewable resources, improving efficiency, reducing carbon emissions, and reforestation efforts.
Global warming
This document discusses global warming, its causes, and potential solutions. It states that global warming is occurring because human activities like burning fossil fuels and deforestation have dramatically increased the amount of carbon dioxide in the atmosphere. It lists several effects of global warming like impacts on water resources, polar regions, forests, and agriculture. Small changes in individual behaviors can collectively make a big difference in reducing carbon emissions, such as driving less, using energy efficient appliances, and recycling more.
Climatechange
Climate change is a significant change in weather patterns over a long period of time, such as 100 years. It has occurred many times before due to both external causes like changes in the sun's activity and earth's orbit, as well as internal causes such as volcanic eruptions and natural feedback loops. Anthropogenic activities like emitting greenhouse gases and land use changes are also contributing to current climate change. While carbon dioxide is used to track human impacts, climate change affects more than just temperature and includes changes to precipitation, humidity, and winds. If left unaddressed, climate change could have major consequences for weather patterns, sea level rise, extreme weather, and force plants and animals to adapt or go extinct, with impacts on
Clean earth pfi
Global warming refers to the long-term rise in the average temperature of the Earth's climate system, primarily due to the increased greenhouse gas emissions from human activities like burning fossil fuels. Climate change is a broader term that includes long-term changes in temperature and weather patterns. The effects of global warming include increased global temperatures, damage to habitats and species, changes to water supply, and rising sea levels. The primary causes of global warming are pollution from burning fossil fuels like coal, natural gas, and oil.
Poster rough draft
Global warming is damaging Arctic ecosystems and displacing animals from their homes. Greenhouse gas emissions are causing the planet to warm, which is having extreme impacts on ecosystems. The document warns about global warming and its effects.
Global warming
The document discusses how greenhouse gases from human activities like burning fossil fuels are adding to the natural greenhouse gases in the atmosphere and causing global warming. Some of the effects of the 1 degree Celsius increase in global average temperatures over the past century include rapidly melting Arctic ice, sea level rise threatening coastal areas and small island nations, and mass bleaching events and die-offs of coral reefs. The document encourages the reader to do their part to address the issue.
Global warming
The document discusses global warming and the greenhouse effect. It explains that greenhouse gases trap heat and make Earth habitable, but the burning of fossil fuels is adding excess greenhouse gases to the atmosphere. This has caused average global temperatures to increase by 1 degree Fahrenheit over the past century. The warming is causing Arctic ice and glaciers to melt rapidly, endangering polar bears and indigenous cultures. Coral reefs are also suffering due to rising water temperatures. The document concludes by emphasizing that humans need to do their part to address this issue, as the Earth is the only planet we have.
global warming
Global warming is the observed century-scale rise in the average temperature of Earth's climate system.[2] Since 1971, 90% of the increased energy has been stored in the oceans, mostly in the 0 to 700m region.[3] Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface.[4] Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.[5] Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850.
Climate Change
Climate is defined as the average weather conditions in a particular region over many years, while weather is the current state of the atmosphere. The average global temperature has increased by around 1°C over the last 100 years, which scientists believe is responsible for more extreme weather events. Normally climate changes very gradually over long periods, but the current warming is occurring much faster than past natural changes. Greenhouse gases and other human emissions are thought to be the main cause of current global warming. Small actions like carpooling and conserving energy can help reduce our emissions and slow further climate change.
Ashu g lobal
Global warming refers to the rising average temperature of the Earth caused by greenhouse gas emissions from human activities like burning fossil fuels. The greenhouse effect occurs naturally but is enhanced by increasing concentrations of greenhouse gases, trapping more heat in the lower atmosphere and leading to global warming. The major greenhouse gases are carbon dioxide, methane, and nitrous oxide, which have all increased due to human activities and contribute to rising global temperatures and sea levels as well as changes to weather patterns and water supplies. Reducing energy usage and switching to renewable energy can help limit the effects of climate change.
Joe Vaughan
Global warming is caused by greenhouse gases that trap heat in the atmosphere. While a warmer climate may benefit some regions by increasing crop yields, overall it risks severe problems like more extreme weather, rising sea levels, and displaced populations. Unless greenhouse gas emissions are significantly reduced, the impacts of climate change are projected to accelerate and intensify over the coming decades.
Louis Burton
Global warming is caused by increased levels of greenhouse gasses like carbon dioxide trapping heat in the atmosphere, with the document discussing the greenhouse effect, the link between CO2 levels and temperature rises, and rising sea levels being problems from increased trapping of heat.
Max Stoneham
Global warming is caused by greenhouse gases like carbon dioxide trapping heat in the atmosphere. Carbon dioxide levels have increased 3% each year due to burning fossil fuels. While global warming may make some cold regions more habitable, its disadvantages include disrupting ocean circulation and causing more severe weather, rising sea levels that flood coastal areas, and increasing desertification.
Oscar Kitchen
Global warming is caused by human activities such as burning fossil fuels that release greenhouse gases into the atmosphere. These gases trap heat and cause the planet to get warmer over time. Small individual actions such as turning off lights when not in use and driving less can collectively make a big difference in reducing greenhouse gas emissions and slowing down the pace of global warming.
Alfie Pugh
Climate change will have both benefits and problems. Longer growing seasons could increase food production in some areas like Europe and North America, strengthening economies. However, tropical diseases may spread further, threatening lives and slowing economic growth. Rising sea levels could flood low-lying areas such as Bangladesh and the Netherlands, displacing millions. Changes in frozen regions and loss of glaciers may impact agriculture and water supplies. Climate change may also cause some species to become extinct, disrupting food chains.
Sam Butler
Global warming is an increase in the Earth's atmospheric temperature caused by greenhouse gases like carbon dioxide and methane trapping heat. Evidence it is occurring includes increasing carbon dioxide levels in the atmosphere. While some crops may benefit from warmer temperatures, global warming threatens our planet, and urgent action is needed to address it.

Gabriel Cox
Global warming is occurring as evidenced by rising temperatures and carbon dioxide levels in the atmosphere. The greenhouse effect, caused by greenhouse gases trapping heat in the lower atmosphere, is enhancing the natural greenhouse effect and warming the planet. If unchecked, global warming will continue to raise sea levels and cause problems, though some regions may initially benefit from a warmer climate.
Mark Williams
Global warming is occurring as evidenced by increases in greenhouse gases like carbon dioxide and methane in the atmosphere, rising sea levels, and rising global temperatures. The main greenhouse gases that cause global warming are carbon dioxide, methane, and nitrous oxide which are released through human activities like burning fossil fuels and agriculture. Global warming will have effects like more extreme weather, loss of species, and coastal flooding if steps are not taken to reduce greenhouse gas emissions and transition to more sustainable energy sources.
Ben Davidson
Global warming is the long-term rise in the average temperature of the Earth's climate system. It is caused mainly by increasing levels of carbon dioxide and other air pollutants that are released into the atmosphere by human activities such as deforestation and burning fossil fuels. The effects of global warming include rising sea levels, stronger storms, more frequent wildfires, and adverse impacts on agriculture and wildlife.
Huw Hallsworths
The document discusses how short wave radiation from the sun is absorbed by the Earth's surface and re-radiated as long wave radiation. Some of this long wave radiation is then absorbed and trapped in the atmosphere by greenhouse gases. It then lists some potential benefits and problems caused by climate change, such as decreased energy consumption but also threats to some species' habitats and low-lying areas from sea level rise.
Alfred Paget
Global warming is causing sea levels to rise due to the greenhouse effect trapping heat in the atmosphere. The main greenhouse gases that cause the greenhouse effect are carbon dioxide and methane, which are released through human activities like burning fossil fuels. While a greenhouse effect keeps the planet warm enough to sustain life, rising sea levels threaten coastal communities and ecosystems.
Adam Farr
Global warming is caused by an increase in average atmospheric temperatures from burning fossil fuels, which overloads our atmosphere with greenhouse gases. This greenhouse effect occurs when short wave radiation from the sun is absorbed by the earth's surface and re-radiated as long wave radiation, which is then absorbed and trapped by greenhouse gases in the atmosphere. Both global warming and the greenhouse effect have serious effects on the environment like shrinking glaciers and rising sea levels, and can impact areas like alpine ski resorts, the spread of diseases, income, and health. While comparisons show the greenhouse effect and global warming can have disastrous long term effects, reducing greenhouse gas emissions may have more pros than cons.
Ben Risebrow
Global warming is causing rising average surface temperatures around the world. As the planet warms, it leads to long-term changes in weather patterns, rising sea levels, and more extreme weather events. The continued greenhouse gas emissions from human activities like burning fossil fuels are the main cause of the current global warming trend according to multiple scientific reports and studies.
Ned Thomas
Global warming is caused by an increase in greenhouse gases trapping heat in the atmosphere, which can raise sea levels and threaten coastal cities and islands. Certain gases like carbon dioxide and methane accumulate in the atmosphere and enhance the natural greenhouse effect, warming the planet. Unless greenhouse gas emissions are reduced, scientists warn that climate change effects will continue to worsen over time, resulting in more extreme weather, rising oceans, species extinction and other environmental problems.
George Turnbull
This diagram shows the greenhouse effect and how increased levels of greenhouse gases like carbon dioxide in the atmosphere lead to rising global temperatures. It depicts shortwave radiation from the sun being absorbed by the earth and longwave radiation being trapped by greenhouse gases, causing the planet to warm. Data on the graph shows a correlation between increasing carbon dioxide levels and rising temperatures since 1000 AD, with a steep rise beginning with the Industrial Revolution. It warns that rising global temperatures are contributing to sea level rise of 3.5 mm per year, threatening coastal cities.
Ollie Dennis
Global warming is the long-term rise in the average temperature of the Earth's climate system. It is caused mainly by increasing levels of carbon dioxide and other air pollutants that are released into the atmosphere by human activities such as deforestation and burning fossil fuels. The effects of global warming include rising sea levels, stronger storms, more frequent wildfires, and adverse impacts on agriculture and wildlife.
Pakistan Floods
Heavy monsoon rains caused widespread flooding across Pakistan in 2010, affecting over 20 million people. The floods were considered the worst in Pakistan's history, destroying infrastructure and displacing many residents from their homes. Relief efforts struggled for months to help those impacted by the massive flooding and damage across the country.
Flood Magnitude VLE
Hydrologists use records of past river discharge levels over long periods to predict future flood likelihoods and return periods. They rank discharge levels and calculate recurrence intervals using a formula, which allows them to plot interval against discharge on a graph. This graph's line of best fit can then predict when the next flood of a particular magnitude might occur, known as its return period. The document asks the reader to use this process and graph to determine return periods for example discharges from the East Fork of the Carson River based on recordings from 1997 and 1955 over a 200 year period.
Alex Wilkinson
Global warming is caused by an increase in greenhouse gases like carbon dioxide trapping heat in the lower atmosphere and warming the planet. This leads the surface temperature to rise which increases the chance of sea levels rising and coastal areas flooding as ice caps melt. The main greenhouse gases that cause this effect are carbon dioxide and methane which are emitted through human activities like burning fossil fuels.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Editor's Notes
- Welcome to my presentation on Global Warming
- The Greenhouse Effect is where the Sun emits Short Wave Radiation (insolation) which then hits the Earth’s Surface and either gets absorbed (heating up the surface) or gets re-radiated as Long Wave Radiation and gets absorbed by the Greenhouse Gases which, in turn, heat up the Atmosphere.
- As the CO2 levels in the atmosphere rise, so does the temperature. This means that the CO2 is absorbing more of the heat from the suns rays and subsequently heating up the Earth. This means that if the CO2 levels continue to rise, then the temperature of the planet will continue to rise, with possibly dire consequences.
- CO2 is not the only Greenhouse Gas, but it is the most prominent one, taking up ~56% of the greenhouse gases. Other Greenhouse Gases are Methane, that takes up ~16%, Halocarbons, that take up ~12%, Ozone, that takes up ~10% and finally Nitrous Oxide that takes up ~5%, with the remaining other gases too insignificant to have an impact.
- As you can see from the graphs, the majority of Human Greenhouse Gas Emissions are caused by Energy. This is because the most popular way to produce energy is in a power plant, where Fossil Fuels are burned and used to create the energy that we use. When the Fossil Fuels are burnt, there are bi-products, and these are released into the atmosphere and are greenhouse gases.
- Here are the main reasons of Sea level rise: Melting of glaciers, thermal expansion, melting of Antarctic ice sheet and ice loss from Greenland. Many instruments of measurement, most notably satellite measurements, tell us that over the past 100 years, the Global Mean Sea Level has raised by 4 to 8 inches (10 to 20 centimetres). However, the annual rate of rise over the past 20 years has been 0.13 inches (3.2 millimetres) a year, roughly twice the average speed of the preceding 80 years.
- Global Warming could lead to some very bad problems, including: The Rise Of Sea Level (this happens because as the temperature of the earth heats up, so does the water, which results in it expanding and taking up more space, as well as this, the heat melting glaciers has a big impact on the sea level rise). Some Animals Habitats are being destroyed, the most famous example is the Polar Bear’s Iceland habitat is melting. And finally Desertification, this is when the rising heat of the earth causes more water to evaporate, resulting in a desert being formed.
- People sometimes think that Global Warming can only cause problems, but there are many benefits as well, one being that the temperature of Earth isn't much lower than it is. Some other future benefits are that the seasons in which you can grow crops will be lengthened, which means that more stock will be harvested. As well as this, some places that cant grow there own crops, will be able too. Another big benefit is the resources of the Arctic. No one actually knows what resources the arctic has to offer for example it could be a rich oil plain, or it could have certain rare minerals underground that we need, the possibilities are almost endless.
