Why is the Earth getting warmer?
Human actions, especially the burning of fossil fuels, which increases the amount of heat-trapping greenhouse gases in the Earth’s atmosphere, are to blame for the long-term warming of the Earth’s surface that has been happening since the pre-industrial period (between 1850 and 1900). This phrase means something different than “climate change.”
It is thought that humans have raised the average temperature of the world by about 1 degree Celsius since the pre-industrial era (1.8 degrees Fahrenheit). Every ten years, this number goes up by more than 0.2 degrees Celsius (0.36 degrees Fahrenheit). Since the 1950s, people have done things that have caused the current warming trend, which is happening at a rate that has never been seen before in thousands of years. in order to develop some general knowledge of it, we suggest you to get acquainted with global warming word search.
What does it mean when we say “climate change”?
Climate change is changing the average weather patterns that have come to define the local, regional, and global climates of Earth. People have seen that these changes lead to a wide range of consistent effects.
Since the middle of the 20th century, people, especially those who use fossil fuels, have changed the climate of Earth. More heat-trapping greenhouse gases are now in the Earth’s atmosphere, which raises the average surface temperature of the planet. Changes in climate can also be caused by natural processes that people have stopped from happening. This includes both internal and external forcings, such as cyclical ocean patterns like El Nio, La Nia, and the Pacific Decadal Oscillation, as well as volcanic activity, changes in the Sun’s energy output, and changes in the Earth’s orbit.
Scientists use computer models and measurements taken from the ground, the air, and space to study and track how the climate has changed in the past, now, and in the future. The melting of the Earth’s poles and mountain glaciers, changes in the number and strength of extreme weather events like hurricanes, heat waves, wildfires, droughts, floods, and rain, and changes in cloud and plant cover are all important signs of climate change.
Food security can’t happen without water security
There is not enough clean, fresh water to feed and support a growing global population, make sure that development is sustainable, and keep the health of our planet. As it is now, there isn’t enough water to feed everyone on the planet and get rid of hunger and poor nutrition. So, better water management is needed to make sure that the world’s food supply is safe.
It goes without saying that farms need irrigation to make more food, make more money, and be less affected by weather changes. But there are other ways in which water affects nutrition and food security. With better irrigation management, more kinds of food can be grown, especially crops that grow during the dry season and foods that are high in micronutrients, like fruits and vegetables. Women’s empowerment and well-being are helped by improvements in how easy it is to get water and how clean it is, as well as by new technologies for getting water. They also save time and make people healthier. The risk of getting infectious diseases and being exposed to feces is lessened when water and wastewater are used well for all their different purposes.
