Many people think that climate change mainly means warmer temperatures. But the rise in temperature is only the beginning of the story. Since the Earth is a system in which everything is interconnected, changes in one area can affect changes in all the others. Climate protection requires significant financial investment by governments and businesses. But inaction on climate change costs far more. A crucial step is for developed countries to meet their commitment to provide $100 billion a year to developing countries to help them adapt and transition to greener economies. COP26 – Direct links between climate change, health and migration must be urgently addressed – IOM, WHO, Lancet Migration Resolution on Climate Change and Health WHA 61.19 (2008): Resolution on climate change and health at the sixty-first World Health Assembly on the serious risk that climate change poses to global health and the necessary actions by WHO and States Members. The two most popular terms used to describe the rise in Earth`s temperatures are global warming and climate change. These relate to short- and long-term weather and climate trends.
Although they are often used interchangeably, there is a slight difference between them: climate forcing refers to how climate affects the physical, chemical and biological characteristics of a region. Finally, the solar energy absorbed by the Earth is reflected back into space in the form of infrared radiation (thermal radiation). It interacts with the entire climate system – atmosphere, oceans, land surfaces and ice sheets. Radiant fluxes in the atmosphere (Figure 1.1) are very important for determining climate. The main gases that make up the atmosphere, nitrogen and oxygen, do not interact with infrared radiation. However, some gases, present in smaller quantities, absorb infrared radiation that rises from the Earth`s surface and radiate it again in all directions, including downwards. In this way, they impede the outflow of infrared energy from Earth to space. This is called the “greenhouse effect,” and the gases that cause it by interacting with infrared radiation are called greenhouse gases. The most important are water vapour, carbon dioxide (CO2) and methane. The greenhouse effect was identified more than a century ago; The Earth`s surface would be about 33°C cooler without them, so the Earth remains habitable. What is climate adaptation? Why is this so important for each country? Find out how we can protect lives and livelihoods in the face of climate change.

What makes greenhouse gases one of the main causes of climate change are their increased emissions relative to the growth of human civilization. For example, carbon dioxide is present in nature, but our atmosphere currently contains too much because fossil fuels are burned. Here are some other steps we can take to slow climate change: “climate change” and “global warming” are often used interchangeably, but have different meanings. Similarly, the terms “weather” and “climate” are sometimes confused, although they refer to events with very different spatial and temporal scales.
Climate change adaptation refers to adaptations that societies or ecosystems make to limit the negative impacts of climate change or to take advantage of opportunities arising from climate change. Adaptation can range from farmers growing more drought-resistant crops to coastal communities assessing how best to protect themselves from sea levels. Capacity building on climate change and human health The cause of today`s climate change is largely human activities, such as the burning of fossil fuels such as natural gas, oil and coal. When these materials are burned, so-called greenhouse gases are released into the Earth`s atmosphere. There, these gases trap heat from the sun`s rays into the atmosphere, causing an increase in the Earth`s average temperature. This increase in global temperature is called global warming. Global warming affects the local and regional climate. Throughout Earth`s history, the climate has been constantly changing. When this happens naturally, it is a slow process that has taken place over hundreds and thousands of years. The human-influenced climate change that is happening now is happening much faster.
Climate science studies how climate affects the natural order on a global scale. Rising global temperatures have the potential to raise sea levels, raise sea levels, change rainfall and local climatic conditions. Climate change deniers often confuse weather with climate. If you`ve ever heard someone say that global warming doesn`t exist because of a recent prolonged cold snap that led to record temperatures, you know what we mean. These are some of the many examples of climate change that do not take into account its effects on plants, animals and insects. While climate change science primarily reflects global changes, it can also be useful for tracking changes in smaller geographic locations, including storms, droughts, floods, and more.
