Global warming is caused by greenhouse gases like carbon dioxide that trap heat in the atmosphere. This leads to climate change, or long-term shifts in weather patterns including increased temperatures and more extreme storms. The main cause is excessive carbon dioxide from human activities like burning fossil fuels and deforestation. If left unaddressed, global warming will have serious economic and environmental consequences, including rising sea levels, stronger hurricanes, species extinction, and disruption of ecosystems and food supplies. Individual actions like driving efficient vehicles and using energy-saving light bulbs can help reduce greenhouse gas emissions and fight global warming.

Climate change refers to long-term shifts in weather patterns due to global warming, which is an increase in average temperatures caused by greenhouse gases. The greenhouse effect occurs when gases like carbon dioxide trap heat in the atmosphere. If human activities that release greenhouse gases are not reduced, the Earth could warm by 7.2 degrees by 2100, with serious consequences like disrupted weather, rising sea levels, and damage to plants and animals. While some argue efforts to reduce emissions will be expensive, the costs of inaction include worse agricultural output and more natural disasters. The document concludes that humans should take action to minimize their contributions to climate change.

Media workshop - Climate Change Adaptation
The document summarizes key findings from the IPCC AR5 Synthesis Report. It notes that global warming has already reached 1.0°C since pre-industrial times due to human activities, and at the current rate of increase we will likely reach 1.5°C between 2030 and 2050. While past emissions alone do not commit the world to 1.5°C of warming, the likelihood and severity of impacts increase with additional warming. Limiting warming to 1.5°C rather than higher levels like 2°C can help achieve other global goals and has clear benefits for people, ecosystems, and livelihoods worldwide. Unprecedented transitions will be needed across all aspects of society to limit warming to 1

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.
Global Warming: Why are We Not Taking it Seriously?
Certain human activities have been causing environmental changes over the past few decades and these are not good.

The document discusses the effects of global warming, including increasing average temperatures and drastic climate changes due to greenhouse gases trapping heat in the atmosphere. Some consequences of global warming mentioned are melting ice caps, rising sea levels, and stronger hurricanes. The document also notes arguments that global warming may be caused more by natural events than human activity.
Effect of global warming PPT EVS
Global warming refers to the long-term rise in the average temperature of the Earth's climate system, primarily due to human activities that increase greenhouse gas emissions into the atmosphere. The main causes of global warming are greenhouse gases like carbon dioxide, methane, and nitrous oxide emitted from burning fossil fuels, large-scale deforestation, and agriculture. As the Earth's temperature increases, sea levels are expected to rise and extreme weather events are predicted to become more frequent due to climate change. To control global warming, actions need to be taken to reduce greenhouse gas emissions through using public transportation, renewable energy, capturing methane, and improving energy efficiency. Unabated global warming could flood coastal cities as melting ice causes sea levels to rise by
Global Warming presentation topic .pptx
The document discusses global warming, its causes, effects, and potential solutions. It defines global warming as the gradual heating of the Earth's surface caused by human activities like burning fossil fuels. It identifies both human causes such as deforestation, industrialization, and overpopulation as well as natural causes like volcanoes and melting permafrost. The effects of global warming include rising temperatures, threats to ecosystems, climate change, and spread of diseases. Potential solutions involve reducing greenhouse gas emissions and transitioning to renewable energy sources.

Global warming is caused by increased levels of greenhouse gases like carbon dioxide and methane trapped in the atmosphere due to human activities like burning fossil fuels. If greenhouse gas emissions continue rising, scientists project that global temperatures will increase significantly by the end of the century. Rising temperatures will lead to severe consequences such as melting polar ice caps, more extreme weather, rising sea levels, and mass extinctions of plants and animals. Collective actions like reducing carbon emissions from transportation, electricity use, and implementing cap-and-trade programs can help prevent the worst effects of climate change.
Nick and stephen 2
The document discusses the causes and effects of climate change and global warming. The primary causes are the burning of fossil fuels and deforestation, which increase levels of carbon dioxide and other greenhouse gases in the atmosphere. This traps heat and warms the planet, leading to consequences like more extreme weather, rising sea levels, and melting ice caps. While some skeptics do not believe humans are responsible, the document expresses the view that humans contribute somewhat but that climate change is also part of a natural cycle. Fighting global warming involves reducing waste and emissions through actions like using less energy and driving less.

This document discusses various cloud formation processes and types of precipitation. It explains that temperature changes during cloud formation can be adiabatic. Orographic lifting and frontal wedging are processes where air is forced to rise over geographic features or air masses. Convergence and localized convergence involve the coming together of air masses. Condensation allows water vapor to change to liquid water droplets. The main cloud types are categorized by height as high, middle, and low clouds. Fog forms through similar cooling processes as clouds near the surface. Cold cloud precipitation involves freezing nuclei while warm cloud precipitation relies on collisions. Rain, snow, sleet, glaze and hail are different forms of precipitation.

When air rises and expands, it cools through adiabatic processes. This cooling can cause water vapor in the air to condense into clouds and precipitate out as rain, snow, sleet or hail depending on temperature levels. Clouds are classified based on their height and physical structure into cirrus, altostratus and nimbostratus clouds that form at high, middle and low altitudes respectively.
3jlaubach
Unequal heating of the Earth's surface causes air temperatures to change without a change in energy. This leads some parts of the Earth to be warmer or cooler than others. When warm air rises and is blocked or forced upward by cooler air, various cloud types can form through condensation. Precipitation occurs through processes like collision-coalescence in warm clouds or Bergeron process in mixed-phase clouds, forming rain, snow, sleet, hail, or freezing rain depending on temperature.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
