What Is Going To Happen If Global Warming Continues – What causes climate change? And how does this relate to global warming? Learn about the impacts and consequences of climate change and global warming on the environment and our lives.
The planet is warming, from the North Pole to the South Pole. Since 1906, the average global surface temperature has increased by more than 1.6 degrees Fahrenheit (0.9 degrees Celsius)—even more in sensitive polar regions. And the consequences of rising temperatures do not wait in the distant future – the consequences of global warming are being felt right now. Heat melts glaciers and sea ice, changes precipitation patterns, and sets animals in motion.
What Is Going To Happen If Global Warming Continues
Many people think of global warming and climate change as synonymous, but scientists prefer to use “climate change” when describing the complex changes currently affecting our planet’s weather and climate systems. Climate change includes not only rising average temperatures, but also extreme weather events, changing wildlife populations and habitats, rising sea levels, and many other effects. All of these changes are occurring as humans continue to add heat-trapping greenhouse gases to the atmosphere.

Climate change is a real and serious problem. In this video, scientist Bill Nye explains what causes climate change, how it affects our planet, why we need to act now to reduce its effects, and how each of us can do our part to solve the problem.

Our Planet Is Warming. Here’s What’s At Stake If We Don’t Act Now.
It seems like every week there’s a terrifying new report about how man-made climate change will destroy the world’s ice sheets, drive the extinction of up to 1 million species of animals, and – if it’s not too bad – make our beer very, very expensive. A new research paper from an Australian think tank this week argues that those other reports are somewhat off the mark; the risks of climate change are actually much, much worse than anyone can imagine.
According to the document, climate change poses a “near to medium-term threat to the existence of human civilization” and there is a strong possibility that society could collapse as early as 2050 if serious mitigation measures are not taken in the next decade.
Published by the Melbourne-based Breakthrough National Center for Climate Restoration (an independent climate policy think tank) and written by a climate researcher and former fossil fuel executive, the article’s central thesis is that climate scientists are too limited in their predictions about how climate change will will affect the planet in the near future.

The current climate crisis, they say, is bigger and more complex than people have ever faced before. Common climate models – such as those used by the United Nations Panel on Climate Change (IPCC) in 2018 to predict that a 3.6 degree Fahrenheit (2 degree Celsius) rise in global temperatures could put a threat to hundreds of millions of people. numerous interconnected geological processes of the Earth; as such, they do not adequately predict the magnitude of possible consequences. True, the authors write is probably much worse than any models can understand.
Climate Change Facts That Prove We’re In A Climate Emergency
What would an accurate worst-case picture of a climate-damaged planet’s future actually look like? The authors present one particularly grim scenario that begins with world governments “politely ignoring” the advice of scientists and the public’s desire to decarbonize the economy (find alternative energy sources), leading to a 5.4 F (3 C) increase in global temperatures by 2050 g. At this time, the ice covers of the world are disappearing; severe droughts are killing many trees in the Amazon rainforest (removing one of the world’s largest carbon offsets); and the planet sinks into a feedback loop of ever warmer, ever deadlier conditions.
“Thirty-five percent of the world’s land area and 55 percent of the world’s population are exposed to lethal heat for more than 20 days a year, exceeding the threshold for human survival,” the authors suggested.
Meanwhile, droughts, floods and forest fires regularly devastate the country. Almost a third of the planet’s land is turning into a desert. Entire ecosystems are being destroyed, starting with the planet’s coral reefs, tropical forests, and arctic ice sheets. The world’s tropics have been hardest hit by these new climate extremes, which are devastating the region’s agriculture and turning more than 1 billion people into refugees.
This mass movement of refugees, combined with shrinking coastlines and a severe drop in food and water supplies, is beginning to strain the fabric of the world’s largest nations, including the United States. Armed conflicts over resources are likely, culminating in nuclear war.
Climate Change Facts & Faqs
The result, according to the new paper, is “instant chaos” and possibly “the end of human global civilization as we know it.”
How to avoid this catastrophic vision of the future? Only with the people of the world who accept climate change as an emergency and get to work – immediately. According to the authors of the work, humanity has about ten years left to build a global movement to transition the world economy to a system of zero carbon emissions. (Achieving zero carbon requires either no carbon emissions or balancing carbon emissions with carbon removal.) The effort required to do so “would be comparable in scale to the emergency mobilization of World War II,” he wrote to the authors.
The new program document was approved with a foreword by Adm. Chris Barry, retired Chief of Defense Australia and senior commander of the Royal Navy, who testified before the Australian Senate about the devastating potential of climate change for national security and general human well-being.
“I told the [Senate] inquiry that, after nuclear war, man-made global warming is the greatest threat to human life on the planet,” Barry wrote in the new paper. “Human life on earth may be on the way to extinction, in the most horrific way.” century before the human expansion of the “greenhouse effect” – the warming that occurs when the atmosphere traps heat that is radiated from the Earth into space.
How Climate Research Can Adapt To The Imminent Threat Of Global Warming
Life on earth depends on the energy that comes from the sun. About half of the light energy that reaches the Earth’s atmosphere passes through the air and clouds to the surface, where it is absorbed and radiated as infrared heat. About 90% of this heat is then absorbed by greenhouse gases and re-emitted, slowing the loss of heat to space.
Over the past century, the burning of fossil fuels such as coal and oil has increased the concentration of carbon dioxide (CO2) in the atmosphere.
). This increase occurs because the process of burning coal or oil combines carbon with oxygen in the air to form CO
. To a lesser extent, clearing land for agriculture, industry, and other human activities has increased the concentration of greenhouse gases.
Climate Change: Evidence And Causes
Ice cores are the best source of historical data for scientists. Other tools for studying Earth’s ancient atmosphere include tree growth rings, which provide a rough record of the temperature, humidity, and cloud cover of each growing season about 2,000 years ago. Corals also form growth rings that provide information about temperature and nutrients in the tropical ocean. Other proxies, such as benthic cores, extend our knowledge of the past by about a billion years.
The industrial activity on which our modern civilization depends has increased the level of carbon dioxide in the atmosphere by almost 50% since 1750. This increase is linked to human activity because scientists can see a characteristic isotopic signature in the atmosphere.
In its sixth assessment report, the Intergovernmental Panel on Climate Change, made up of scientific experts from around the world, concluded that an unequivocal increase in CO
, methane, and nitrous oxide in the atmosphere during the industrial age are the result of human activity, and this human influence is a major driver of many of the changes observed in the atmosphere, ocean, cryosphere, and biosphere.

“Since systematic scientific assessments began in the 1970s, the impact of human activity on the warming system has evolved from theory to established fact.” – Intergovernmental group of experts on changes
Scientists use a metric called Total Solar Irradiance (TSI) to measure changes in the energy the Earth receives from the Sun. The TSI includes the 11-year solar cycle and solar flares/storms on the solar surface.
Research suggests that solar variability has played a role in past changes. For example, a decrease in solar activity combined with increased
