Based on the evidence, it is accepted that climate change is happening and that the climate will change even more due to our fossil fuel-based economy, the increasing number of people and of their growing wealth. . The increase in greenhouse gases has already started to have impacts on the climate, natural ecosystems and human societies. It is clear that average surface temperatures have been increasing and this trend will continue as more carbon dioxide is released into the atmosphere. The recent warming is unprecedented, both in its magnitude and its speed. The warming predicted for the 21st century risks creating serious problems for natural ecosystems and human societies. Water resources are already under increasing stress and are at risk of decline. This will inhibit crop growth and negatively impact other water uses, such as water use for industries and water supply for the human population. This will lead to even more serious food shortages. Glaciers and ice caps are already retreating, and will retreat further, leading to changes in the total and annual flow cycle of some rivers, further threatening water supplies. The impact on ecosystems will affect the distribution and productivity of plant and animal species as well as water supply. The loss of biodiversity risks being accelerated by climate change. There will be an increase in extreme weather events, such as an increase in the magnitude and frequency of floods, an increase in the intensity, frequency and duration of droughts, as rates of evaporation will be higher. Higher average temperatures and possibly increased variability will likely lead to increased frequency and severity of heat waves, causing additional deaths from heat stress and vector-borne diseases...... middle of paper .... ..do. Climate change represents a major challenge for the development of future generations. It is up to our generation to make decisions regarding greenhouse gas emissions that will not pose a significant risk of serious adverse consequences to the future generation. At global and national levels, responses to climate change must focus on long-term sustainable solutions to ensure that the well-being and needs of future generations are met. This will mean minimizing the impact of greenhouse gas emissions for future generations. The sooner we manage to control climate change, the less future generations will have to suffer its consequences. Future generations should also benefit from a healthy world, a world with a sustainable future and a world in which we ourselves would like to live. It is for future generations that we will meet the challenge of climate change..
