- Climate change is destroying us
- Our earth has gone through a lot of changes for billions of years, sometimes it was a balloon of hot gases and sometimes it was covered with a sheet of ice for millions of years. Its rise and fall in temperature has always affected plants, animals and human history here. Although during the last 400,000 years, the temperature has been four to eight degrees lower than today, there have been many periods of high temperatures. Came. These changes always affected the rainfall system, changed the nature of vast deserts and created lush green plains.
- The glaciers melted, causing sea levels to rise, floods, and then these seas continued to transform into flat plains. These changes that took place in prehistoric times decided where forests and edible plants could grow and where shepherds could find green fields. Plants, animals and human populations of each era kept adapting to new environments. Keep migrating and dying. Finally, 160,000 years ago, a big event happened and the human being, persecuted by nature, decided to leave Africa somewhere. Human populations left Africa and began to spread around the world. migrated to the eastern regions of the Nile and the Mediterranean Sea, then thousands of years later a group of them left Africa and migrated to the Arabian Peninsula via Bab al-Mandab. It is said that all the people on the planet today belong to this group. From here they crossed the Strait of Hormuz and entered Asia. A few thousand years later, a group of them didn't like the place either and packed up for the regions of Southeast Asia and China. Generation after generation, this arduous journey continued and humans traveled through Australia and New Guinea to Southwest Asia, Liberia. And eventually reached America. The main reason for this difficult journey of man spanning tens of thousands of years was the various environmental changes on this planet and this environmental change has become a special topic once again in the last few years. Major universities around the world are conducting research on climate change and global warming, holding conferences and seminars, and signing agreements to protect the planet from the devastating effects of severe climate change

- Environmental scientists agree that global temperatures are expected to increase by 5.2 to 10 degrees Fahrenheit over the next century, causing extreme climate change. According to scientists, climate change has been a feature of this planet and numerous changes have taken place since its birth, but its pace has been very slow. The growth has accelerated to about 30% which is a major cause of climate change.
- In October last year, the World Environment Organization (IPCC) released a report that called for limiting global warming to 5.1 degrees Celsius. The report said that for this purpose, governments should reduce greenhouse gas emissions by 2030. It will have to be reduced by 45%. However, according to a recent study, after the decrease in carbon dioxide in the last four years, it has started to increase again. At a conference on climate change in Poland in December, experts warned that the Earth had reached a "critical juncture." They said any delay in taking preventive measures would be disastrous. What this damage might be, can be gauged from the report, which states that climate change is increasing the threat to glaciers in the Himalayan and Hindu Kush mountain ranges. If the current pace of carbon dioxide emissions is not controlled, two-thirds of these glaciers may disappear, experts say, and the mountains of K-Too and Mount Everest will turn into bare rock in less than a century. Pollution and rising temperatures can accelerate snowmelt. Pakistan, Bangladesh, Afghanistan, India, Bhutan, China, Myanmar and Nepal will be directly affected by these changes. It should be noted that the glaciers of the Himalayas and Hindu Kush provide water to the world's most important rivers, the Indus, Ganges, Yellow, Mekong and Irrawaddy, and are also a source of food, energy, clean air and income for billions of people in this region. Another scientific study has revealed that 40% of the insects on the planet are at risk of extinction due to climate change. Remember that insects are of key importance to human life and they contribute to 75% of fertilization, they make the soil fertile and keep the number of harmful insects under control. These are just two devastating examples of climate change, the whole earth is currently under the influence of climate change, and news of natural disasters related to it continues to emerge every day.
| I agree that climate change is a serious problem that affects all of us. Climate change is the long-term shift in the Earth’s average temperatures and weather conditions, caused mainly by human activities that increase greenhouse gas emissions1. Climate change has many negative impacts on the environment, such as droughts, floods, fires, storms, sea level rise, and biodiversity loss12. Climate change also threatens human health, food security, water availability, and social stability |

| We need to take urgent action to limit global warming and adapt to the changing climate. Some of the actions we can take include reducing our use of fossil fuels, switching to renewable energy sources, planting more trees, conserving water, and supporting green policies and initiatives We can also raise awareness and educate others about the causes and effects of climate change, and how we can all contribute to solving this global challenge |

| Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun’s activity or large volcanic eruptions. But since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels like coal, oil and gas. |
|---|
| Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures. |
|---|
| The main greenhouse gases that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and cutting down forests can also release carbon dioxide. Agriculture, oil and gas operations are major sources of methane emissions. Energy, industry, transport, buildings, agriculture and land use are among the main sectors causing greenhouse gases. |

Humans are responsible for global warming
Climate scientists have showed that humans are responsible for virtually all global heating over the last 200 years. Human activities like the ones mentioned above are causing greenhouse gases that are warming the world faster than at any time in at least the last two thousand years.
The average temperature of the Earth’s surface is now about 1.1°C warmer than it was in the late 1800s (before the industrial revolution) and warmer than at any time in the last 100,000 years. The last decade (2011-2020) was the warmest on record, and each of the last four decades has been warmer than any previous decade since 1850.
Many people think climate change mainly means warmer temperatures. But temperature rise is only the beginning of the story. Because the Earth is a system, where everything is connected, changes in one area can influence changes in all others.
The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity.
People are experiencing climate change in diverse ways
- Climate change can affect our health, ability to grow food, housing, safety and work. Some of us are already more vulnerable to climate impacts, such as people living in small island nations and other developing countries. Conditions like sea-level rise and saltwater intrusion have advanced to the point where whole communities have had to relocate, and protracted droughts are putting people at risk of famine. In the future, the number of people displaced by weather-related events is expected to rise
Every increase in global warming matters
In a series of UN reports, thousands of scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5°C would help us avoid the worst climate impacts and maintain a livable climate. Yet policies currently in place point to a 3°C temperature rise by the end of the century.
The emissions that cause climate change come from every part of the world and affect everyone, but some countries produce much more than others.The seven biggest emitters alone (China, the United States of America, India, the European Union, Indonesia, the Russian Federation, and Brazil) accounted for about half of all global greenhouse gas emissions in 2020.
Everyone must take climate action, but people and countries creating more of the problem have a greater responsibility to act first.
We face a huge challenge but already know many solutions
- Many climate change solutions can deliver economic benefits while improving our lives and protecting the environment. We also have global frameworks and agreements to guide progress, such as the Sustainable Development Goals, the UN Framework Convention on Climate Change and the Paris Agreement. Three broad categories of action are: cutting emissions, adapting to climate impacts and financing required adjustments.
- Switching energy systems from fossil fuels to renewables like solar or wind will reduce the emissions driving climate change. But we have to act now. While a growing number of countries is committing to net zero emissions by 2050, emissions must be cut in half by 2030 to keep warming below 1.5°C. Achieving this means huge declines in the use of coal, oil and gas: over two-thirds of today’s proven reserves of fossil fuels need to be kept in the ground by 2050 in order to prevent catastrophic levels of climate change.
- Adapting to climate consequences protects people, homes, businesses, livelihoods, infrastructure and natural ecosystems. It covers current impacts and those likely in the future. Adaptation will be required everywhere, but must be prioritized now for the most vulnerable people with the fewest resources to cope with climate hazards. The rate of return can be high. Early warning systems for disasters, for instance, save lives and property, and can deliver benefits up to 10 times the initial cost.
We can pay the bill now, or pay dearly in the future
- Climate action requires significant financial investments by governments and businesses. But climate inaction is vastly more expensive. One critical step is for industrialized countries to fulfil their commitment to provide $100 billion a year to developing countries so they can adapt and move towards greener economies
- To get familiar with some of the more technical terms used in connection with climate change, consult the Climate Dictionary.
- In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels.[3][4] Fossil fuel use, deforestation, and some agricultural and industrial practices add to greenhouse gases, notably carbon dioxide and methane.[5] Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming.
Climate change has an increasing impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common.[6] Amplified warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss.[7][8] Higher temperatures are also causing more intense storms, droughts, and other weather extremes.[9] Rapid environmental change in mountains, coral reefs, and the Arctic is forcing many species to relocate or become extinct.[10] Even if efforts to minimise future warming are successful, some effects will continue for centuries. These include ocean heating, ocean acidification and sea level rise.[11]
Climate change threatens people with increased flooding, extreme heat, increased food and water scarcity, more disease, and economic loss. Human migration and conflict can also be a result.[12] The World Health Organization (WHO) calls climate change the greatest threat to global health in the 21st century.[13] Societies and ecosystems will experience more severe risks without action to limit warming.[14] Adapting to climate change through efforts like flood control measures or drought-resistant crops partially reduces climate change risks, although some limits to adaptation have already been reached.[15] Poorer communities are responsible for a small share of global emissions, yet have the least ability to adapt and are most vulnerable to climate
