Facts about changing climatic conditions can be used to reinforce your main topic. And yes, we can and must act immediately to prevent the worst effects and preserve a livable world for our children, grandchildren and all beings. Having been concerned about this for a long time, including teaching about the problem at the University of California San Diego, I’m left wondering if before the planet can return to prehumanity conditions, humans have to cease to exist.
Human-induced activities are majorly destroying the global climate affecting the biodiversity of the Earth. According to a report by the National Academy of Sciences, for each one degree Celsius of global warming, the area burned by western wildfires will increase by a factor of two to four. Trees help to regulate the global climate by absorbing CO2 from the atmosphere.
Some 500 million people today live in areas affected by erosion, while up to 30 per centof food is lost or wasted as a result. Meanwhile, climate change limits the availability and quality of water for drinking and agriculture. Studies show the current reality is for CO2 emissions to continue climb through 2040. Rising seas or flooding compromises drinking water, human waste water treatment and storm water disposal that, in turn, results in increased risk of waterborne diseases caused by pathogens such as bacteria, viruses and protozoa. Between 1948 and 1994, 68 percent of waterborne disease outbreaks in the US were preceded by extreme precipitation events. Global warming is therefore influencing the fate, transport, transmission, viability and multiplication rate of pathogens in the food chain. Cases of Legionnaires’ disease, spread by contaminated aerosolized water have not surprisingly increased by nearly 200 perce between 2000 and 2009.
The amount of carbon these fires can emit can be massive, further exacerbating overall trends in climate change. The forest and how to be a good american essay peat fires in Indonesia during 1997 were estimateto release upwards of 40 percent of total annual carbon emissions globally.
The most influential example of such climate doomism is undoubtedly Professor Jem Bendell’s ‘Deep Adaptation’, a self-published 2018 paper which holds that accelerating climate change has guaranteed social collapse within the next few decades. Hundreds of thousands of people have downloaded ‘Deep Adaptation’ and the paper has significantly impacted the ideology and strategy of climate movement organizations like Extinction Rebellion. People have changed their life plans based in large part on this paper’s predictions. It is therefore past time to show that Deep Adaptation is wrong — not least because Bendell’s brand of doomism relies heavily on misinterpreted climate science that undermines the credibility of his claims.
That’s because way back then there wasn’t as much carbon dioxide gas in the air. Scientific studies from NOAA and NASA have shown that carbon dioxide and temperature go together. When there is more carbon dioxide in the air, the average air temperature around the earth rises. This causes more water to evaporate, which forms lots of warm, moist air. This is the kind of air that hurricanes need to start up, and they need a steady supply of it to keep them going.
It’s all about keeping our earth in balance to maintain our quality of life. As long as the worldwide economy is defined largely as fossilized capitalism, mass extinctions or the loss of phylogenetic diversity will continue. Among other things, we will also continue to see substantial worldwide fishery losses and the collapse climate change essay conclusion of insect populations. The loss of insect populations will contribute to a profound negative effect on food production. For example, 30 countries are currently experiencing negative crop yields and there is a one in twenty likelihood heat, climate change will cause the failure of corn production in China and the US.
Local black carbon deposits on snow and ice also contribute to Arctic warming. Arctic temperatures are increasing at over twice the rate of the rest of the world. Melting of glaciers and ice sheets in the Arctic disrupts ocean circulation, including a weakened Gulf Stream, further changing the climate. It is caused due to greenhouse gases which mainly consists of methane, carbon dioxide, CFC’s or Chloro Fluro Carbons, etc. Once children understand the difference between weather and climate, and the cause and effect between carbon dioxide in the atmosphere and global warming, they’ll want to know why it matters.
The Accord set the goal of sending $100 billion per year to developing countries for mitigation and adaptation by 2020, and proposed the founding of the Green Climate Fund. As of 2020, the fund has failed to reach its expected target, and risks a shrinkage in its funding. Climate change is driven by rising greenhouse gas levels in the atmosphere. This strengthens the greenhouse effect which traps heat in Earth’s climate system. Due to excessive urbanization, the Earth’s temperature is regularly increasing, and glaciers are melting in the poles. If global warming is not controlled, eventually, the existing life forms on Earth will end soon.
I would like to conclude my global warming speech by saying that the international community, governments and citizens has to come forward to reduce your carbon footprint to save the planet for our future generation.
We need some of this warmth to sustain life on this planet, so some carbon dioxide in the atmosphere is a good thing. However, the more carbon dioxide in the air, the warmer the planet becomes. Our quality of life depends on having fairly predictable climate change essay conclusion weather and a livable climate. Adding more carbon dioxide to the air threatens that, because the additional warmth it causes upsets the balance of natural systems. Older children will appreciate the scientific evidence for climate change.
The rainfall rate and intensity of hurricanes and typhoons is likely increasing. Frequency of tropical cyclones has not increased as a result of climate change. Physical climate models are unable to reproduce the rapid warming observed in recent decades when taking into account only variations in solar output and volcanic activity. As the Sun is the Earth’s primary energy source, changes in incoming sunlight directly affect the climate system. Solar irradiance has been measured directly by satellites, and indirect measurements are available from the early 1600s onwards. There has been no upward trend in the amount of the Sun’s energy reaching the Earth.
If you are unaware of what climate change is, it is a global or regional change in weather patterns that lasts for a long period of time. Climate change is greatly caused by the increased levels of atmospheric carbon dioxide which is produced by the use of fossil fuels, such as exhaust from cars and trucks, burning trash, and factory emissions. These are also contributing to global warming which is, a gradual increase in the overall temperature of the Earth’s atmosphere. Some effects of global warming in the Arctic are rising temperatures in the air and in the water surrounding the Arctic. Another is the loss of sea ice and melting of ice sheets which is caused by the increased temperatures. This also greatly impacts the Arctic plants and animals, they are rapidly dying, decreasing in numbers, possibly leading to their extinction.
