Humans are the only living species of the genus Homo, and we are the most widespread species. There are a little more than 8 billion of us. Humans are characterized by hairlessness, bipedalism, and high intelligence. We have quite big brains that allow for more advanced cognitive skills. It lets us evolve and adapt to different environments and form complex social structures and civilizations. Humans are very social, and due to that, we have formed different values, social norms, languages, and traditions. Humans are also very curious. We like to understand how everything works around us. For this, we have created science, technology, philosophy, mythology, religion, and so on.
Climate change is not just affecting animals, different environments, and habitats. It affects us humans too. Climate change will affect everyone differently. Scientists have found that climate change is going to affect way more people than previously thought, and it will affect different parts of the world differently.

Climate change impacts range from warming temperatures to changes in rainfall, increases in the frequency and intensity of some extreme weather events, and also rising sea levels. All these things will affect our health and infrastructure. It will ruin the food we eat, the water we drink, the air we breathe, and the weather we experience. Flooding can cause the spread of diseases and so on. Climate change is often described as a threat multiplier, as it exacerbates resource shortages and worsens existing social, economic, and environmental factors.

Water is vital for us and for our planet. We need it for drinking, to grow our crops, and to feed our animals. A lot of different animals need freshwater as their habitat. Oceans are important because they help to regulate CO2 levels and therefore sustain global temperatures, transport nutrients, and also support the marine ecosystem. Climate change will change the oceans and freshwater resources that are the foundation for our communities and ecosystems.
Oceans cover about 71% of our planet. Oceans absorb most of the CO2 and heat, and that puts life in them in danger. A big part of our population depends on the seas. We harvest from them. Also, the sea-level changes are affecting the people on the coastlines.
Continuous warming is affecting the freshwater that we can safely use for drinking. Almost half of the population gets their water from the ground. Scientists are predicting that with the increase in cities, the demand for freshwater will increase by 55% by the year 2050. Therefore, we have to manage our water usage carefully.

Climate change is not completely bad. Some plants can benefit from it. For some plants, the length of growth can be longer, and therefore they are able to increase carbon dioxide. However, other effects of a warmer world, such as more pests, droughts, and floods, are less favorable. Scientists have predicted, with different modules, that by the year 2050, suitable croplands will shift. It means that farmers have planted different crops than they did before. Climate change alone will not dictate productivity. Future farming will also be affected by the policy, global demand, and farming methods. For example, in Northern Europe, the length for growing potatoes will be longer, but the soil in Southern Europe will become too dry to grow potatoes.

Together with global warming comes wild weather. We’ll experience more hurricanes, draughts, ice storms, and heat waves. Since 1980, meteorological data has shown the rise of weather-related disasters annually. Because of more frequent storms on the coast, the costs of maintaining the infrastructure are increasing. To decrease the risk and losses, scientists have to come up with new innovations, for example, floating villages.
Global warming brings more weather extremes, hotter days, and longer-lasting heat waves. This causes more heat-related deaths. Exposure to more heat causes heat strokes, dehydration, and cardivascular, respiratory, and cerebrovascular conditions. The extreme heat will likely affect more people who live in northern latitudes because they are not used to this kind of climate.

Climate change is going to affect our health. The effects on health can differ by age, gender, geography, and socioeconomic status. Health experts all around the world are encouraging new measures to help people stay healthy despite floods, droughts, and heatwaves.
Extreme weather can cause power outages. It might put people in danger when we need electricity the most, for example, in hospitals and for transportation. Lower harvests can lead to poor nutrition, hunger, and higher food prices. Higher levels of CO2 in the air can make main crops such as barley and soya less nutritious. The changing environment and severe weather conditions like floods, droughts, and heat waves can also cause mental health problems. Like previously mentioned, with warmer weather, some plants have a longer vegetation period, which means that people who suffer from allergies have to deal with these conditions longer. Also, rainfall might be more frequent, which means more mold, fungi, and indoor air pollutants. Also, diseases that are spread by mosquitoes and ticks are going to spread more widely because the moist and warmer climate suits them.
