Forest fires in eastern Russia, northern Scandinavia, Greenland and Alaska have worsened this year due to climate change causing higher temperatures and a lack of rain. Smoke from the fires can be seen from space and air quality has deteriorated in eastern Russian cities. The fires have released 50 megatons of carbon dioxide, equivalent to Sweden's annual emissions. Experts say the size and location of the fires in the Arctic circle in June are unprecedented and evidence that a warming climate can cause more fires.
Climate Change: Will it Hurt the High End Market?Inman News
Global temperatures have risen about 1 degree Celsius since the pre-industrial era due to increasing levels of human-emitted greenhouse gases like carbon dioxide. Models project further temperature increases between 1 to 4 degrees Celsius by 2100, which will lead to more severe consequences like more frequent heat waves, longer summer seasons, increased wildfires, and rising sea levels that threaten coastal development. Continued warming is expected to exacerbate issues around droughts, hurricanes, climate refugees, and wildfires in the western United States.
Over the last decade, the frequencies of bushfires have become more prevalent. According to a research published in Royal Society Open Science, there had been an increase of 40% in bushfire frequency during the summer, which is believed to indicate an alarming shift in the climate.
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.
Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-twentieth century, and its projected continuation. Factors that contribute to global warming, nevertheless caused mostly by humans, include deforestation, logging, the use of CFCs and HCFCs, and the release of methane gases from cow’s gaseous emissions from their anuses, which is a natural factor that contributes to global warming.

As global temperatures rises , disease epidemic likely to come.pdfthenationaltv
Pathogenic bacteria and human beings have co-existed since time immemorial.Through course of time these microscopic pathogens have evolved several ways to combat resistance.For Instance, these microbes have become anti-biotic resistant and develop new ways of infection. Human beings on the other hand,have developed new ways to cope up with these infections.
Scientists have determined that global warming is caused primarily by human-produced greenhouse gas emissions from activities like burning fossil fuels. The main greenhouse gases are carbon dioxide, methane, and nitrous oxide, which are emitted through activities like driving, electricity production, agriculture, and industrial processes. While natural factors also influence the climate, the current rapid warming trend cannot be explained without accounting for human greenhouse gas emissions. Global effects are already appearing, such as rising temperatures, melting ice sheets and glaciers, sea level rise, and shifts in animal and plant ranges.
Global warming is caused by human-produced greenhouse gas emissions, primarily from the burning of fossil fuels. It is causing rising temperatures worldwide and changes to climate patterns that threaten ecosystems and human communities. While reducing emissions could help limit future warming, some impacts are already unavoidable due to past emissions and warming humanity has already caused. Solutions involve transitioning to renewable energy sources, improving energy efficiency, and carbon sequestration technologies.
The document discusses the scientific consensus on the causes and effects of global warming. It explains that scientists have concluded human greenhouse gas emissions are the main cause of current global warming trends, based on extensive research ruling out natural factors alone. The document outlines some of the major greenhouse gases emitted by human activities that are contributing to increased temperatures worldwide, and provides examples of impacts already occurring like glacial melting as well as potential future impacts if warming continues such as rising sea levels.
Climate is the average weather over a long period and we expect it to remain relatively constant. CC is the single biggest long-term problem we face - the evidence is overwhelming. CC is a far greater threat to the world than international terrorism.
CC is not science fiction……and will soon prove to be a dead-end road for everyone. The key is actually discarding the idea that in order for a country to get rich, stay rich and get richer, you have to put more GHG in the atmosphere. That isn't true and it hasn't been true for years….. If we don't deal with this immediately, we will have island nations flooded; agricultural balance of most countries completely changed; a dramatic increase in the number of severe, unmanageable weather events and epidemic of unknown diseases. Our natural environment is very important in the aspects of peace because when we destroy our resources and our resources become scarce, we fight over that hastening CC.
Global warming is caused by greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere. It is a serious problem that threatens human life and has become a creeping menace. While scientists have identified the cause, we have slept on this issue and allowed nature to decide our fate. If we do not take action to stop global warming through measures like banning fossil fuels, encouraging afforestation, and using eco-friendly products, it could result in catastrophic consequences like more extreme weather, depletion of the ozone layer, and even human extinction. We must take action now for the sake of future generations.
The document summarizes the scientific evidence and consensus on climate change. It explains that human emissions of greenhouse gases are trapping heat and causing the planet to warm at a rate not seen in centuries. This is melting ice, raising sea levels, and shifting weather patterns in ways that threaten ecosystems and human communities. While uncertainties remain, most climate scientists agree that significant impacts are already occurring and will increase substantially if emissions are not reduced.
27 May 1950 - World weather may be warming up.pdfBraydenStoch2
This article discusses evidence that the Earth's climate is warming globally. It notes that glaciers are melting faster, tree lines are moving northward, and Arctic waters now support fish that were previously unable to survive there due to warmer temperatures. While some scientists remain uncertain, most agree that the Northern Hemisphere has been warming since around 1920, with temperatures rising by fractions of a degree each year. Possible causes mentioned include increased sunspot activity and radiation from the sun.
Global warming is causing the polar ice caps to melt rapidly, which will raise sea levels and threaten coastal communities. As temperatures rise due to greenhouse gas emissions, weather patterns are becoming more extreme with more floods, droughts, hurricanes and tornadoes. This melting of the ice caps reduces their ability to reflect the sun's heat back into space, causing further warming in a dangerous feedback loop. If greenhouse gas emissions are not reduced, scientists predict the ice caps could melt entirely by 2100, raising sea levels by 50-90 inches and submerging many major coastal cities under water.
This ppt is about the world's apocalypse, whenever it comes. We describe what can cause the world to end, what are the dangers to be aware of etc. We also explain how to protect oneself, if unfortunately the apocalypse had happened.
Jack oughton global warming - what everyone needs knowJack Oughton
This document discusses the history and science of global warming. It explains that while climate change is a natural process, human activities like burning fossil fuels are enhancing the greenhouse effect and increasing global temperatures. If unchecked, climate change could have severe consequences like widespread desertification, disrupted ecosystems, and flooded coastal regions. While some argue global warming may be exaggerated, the potential risks to humanity mean efforts should be made to reduce our environmental impact and enable adaptation to a changing climate. The document uses Venus as an example of a runaway greenhouse effect and warns we do not want to make Earth similarly uninhabitable.
This document is Pope Francis' apostolic exhortation on the climate crisis titled "Laudato Si'". In it, he discusses the urgent need to address climate change based on scientific evidence that human activity is the dominant cause. He criticizes those who deny or downplay the crisis. Francis argues the issue is a global social problem impacting human dignity. While some impacts are now irreversible, more damage can still be prevented if swift action is taken. However, he expresses concern that a dominant technocratic paradigm prioritizes unlimited growth and human power over nature. Francis calls for rethinking human power and moving beyond this damaging paradigm to recognize humanity's integral relationship with the natural world.
Climate change is occurring due to human activity. The past few years have been the warmest on record and 2016 broke the record set in 2015. Most scientists agree that carbon emissions from human activities are trapping heat in the atmosphere and causing global warming. As the climate warms, ice is melting rapidly in the Arctic and increasing sea levels, wildlife habitats are being threatened, and weather is becoming more extreme with heat waves and coastal flooding increasing in frequency and severity. While the effects of climate change are already apparent, international agreements like the Paris Agreement aim to limit future warming through reductions in fossil fuel use and a switch to renewable energy sources.
Earth's Temperature _ A Brief History Of Recent ChangesIngre1930685
This document discusses changes in Earth's temperature over the past 420,000 years and the role of greenhouse gases like carbon dioxide. Key points:
1. Temperatures varied between around 5-17°C over the past 420,000 years in 100,000 year cycles driven by variations in Earth's orbit and tilt.
2. The last 10,000 years have been remarkably stable until recently, allowing civilization to develop.
3. Carbon dioxide levels never exceeded 300 ppm until the last century due to human activity like burning fossil fuels. Rising CO2 is the primary cause of recent temperature increases.
4. If greenhouse gas emissions continue unabated, temperatures may increase 2-6°C

Tips for Writing Comparison/Contrast Essays
1. Be sure to introduce BOTH stories, in your opening paragraph, and also to tell the reader what the stories have in common that makes it possible to compare them.
2. Make sure that you do actually compare/contrast the stories (for example, ‘Tim, unlike Montresor, kills because it is his job to.’) This will ensure that you end up with a single, cohesive essay, not two mini-essays sitting on top of each other.
3. Make sure that you deal with the things you are comparing (in this case two characters) at equal length.

The document discusses several impacts of global warming, including rising global temperatures leading to more extreme weather, health impacts from heat waves, melting Arctic ice and effects on indigenous communities and wildlife, rising sea levels threatening coastal areas, warming oceans damaging coral reefs, increased risk of drought and wildfires, and evidence that climate change can trigger more earthquakes and volcanic eruptions. It argues that global warming is caused by capitalism and fossil fuel use rather than humanity itself, and that capitalism will need to end for adequate action to be taken to address the climate crisis and ensure survival of human civilization.

The speed of evolutionary changes has greatly increased in the last 10,000 years. The huge increase in population plus the adaptation to new ecology conditions have resulted in strong pressure to produce genetic mutations: for example, to allow digestion of different food sources, to create resistance to unknown pathogens or to adapt skin to new environments. With this recent background, what type of variations can we expect that evolution will bring to humankind in the next 200,000 years? We can find different answers in the action of nature and the action of humans.
The document discusses evidence of global warming due to human activities increasing greenhouse gases. It notes increasing temperatures, more extreme weather like heat waves and flooding, and melting ice contributing to rising sea levels. The Islamic view emphasizes humans' role as caretakers of Allah's creation and avoiding abuse that could disrupt the environment.
This document discusses several major current environmental issues:
1) Pollution, population growth, global warming, waste disposal, climate change, and other issues are negatively impacting the environment.
2) Increased carbon dioxide in the atmosphere from human activities is causing global warming. As the planet warms, glaciers and ice sheets are melting, sea levels are rising, and extreme weather events are becoming more frequent and severe.
3) Warming is also impacting ecosystems and biodiversity as species struggle to adapt to rapid climate change. Key environmental problems like pollution, overpopulation, and resource depletion exacerbate global warming if left unaddressed. Urgent action is needed to transition to renewable energy and more sustainable practices globally
This document discusses global warming and its causes and effects. It states that global warming is caused by both natural phenomena like methane gas releases as well as man-made factors like burning fossil fuels. Some effects of global warming mentioned include rising sea levels threatening coastal areas, melting Arctic sea ice and glaciers, increased frequency and severity of extreme weather events, widespread species extinctions by 2050, disappearance of coral reefs, spread of diseases, economic costs, more wildfires, and increased air pollution and smog.

Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

2. The dangers of melting ice in the frozen Arctic
The seeds of human death are buried somewhere. Viruses in caves carried by
bats. We do not know when and how.
Fifteen thousand nuclear warheads planted by man himself are capable of blowing
up the Earth dozens of times. Nevertheless, what if we know that there is a new
imminent danger, or a new old one that seems to be new. Rapidly melting Arctic
ice may release ancient killer diseases dormant in permafrost. Does that revive the
bacteria from those sunken and frozen depths? This concern is not unjustified.
Frozen Siberia, for example, recorded unprecedented temperatures throughout
history, potentially devastating thirty-eight degrees Celsius. The fires devour the
Amazon, Australia, China and Indonesia. You may be able to say that the entire
planet is already burning with epidemics, wars and poverty. These fires released
huge amounts of carbon dioxide into the atmosphere, highlighting the vicious cycle
of climate collapse. Global warming increases fires, and fires increases global
temperatures.
Climate scientists wonder if these extreme events herald the start of a terrifying
new era of extreme heat in the Arctic. Climate collapse, so to speak, in the far north
of the globe threatens to expose viruses that have remained dormant for a long
time. It may be tens or even hundreds of thousands of years old. It has frozen in
permafrost in the arctic region.
As an example of dormant viruses, an analysis of wastewater in Spain and Italy in
March 2019 showed ten viruses that had not yet been released. Scientists say
bacteria can live for a long time without a doubt, but the debate that remains is
how long they live. A million years, a hundred thousand years, that is exactly what
we do not know. However, how do you resurrect these deadly creatures? Simply,
if it meets a suitable host, it will be reactivated. So if you put a person in a place
that contains frozen viruses associated with the emergence of a pandemic in
earlier times, that person can become infected and cause the virus to multiply, thus
triggering a new pandemic. Therefore, we hope none of these viruses would be
hosted.
