Climate change is happening. Global average temperature has increased about 1.8°F from 1901 to 2016.1 Changes of one or two degrees in the average temperature of the planet can cause potentially dangerous shifts in climate and weather. These real, observable changes are what we call climate change impacts because they are the visible ways that climate change is affecting the Earth. For example, many places have experienced changes in rainfall, resulting in more floods, droughts, or intense rain, as well as more frequent and severe heat waves. Show The planet's oceans and glaciers have also experienced changes—oceans are warming and becoming more acidic, ice caps are melting, and sea level is rising. As these and other changes become more pronounced in the coming decades, they will likely present challenges to our society and our environment. More on Climate Change Impacts Climate change is happening globally, but the effects can differ locally. Certain sectors, regions, and human populations are more vulnerable or have unique risks due to climate change. To learn more about the differing impacts faced by these parts of our environment and society, visit the Climate Change Impacts web area.Seeing the ImpactsClimate change impacts our health, environment, and economy. For example:
Looking AheadElevated concentrations of carbon dioxide will persist in the atmosphere for hundreds or thousands of years, so the earth will continue to warm in the coming decades. The warmer it gets, the greater the risk for more severe changes to the climate and the earth's system. Although it's difficult to predict the exact impacts of climate change, what's clear is that the climate we are accustomed to is no longer a reliable guide for what to expect in the future. Adapting to Climate ChangeAdaptation helps us prepare for some of the likely effects of climate change by reducing their impacts on ecosystems and people's well-being. Examples of adaptation include strengthening water conservation programs, upgrading stormwater systems, developing early warning systems for extreme heat events, and preparing for stronger storms through better emergency preparation and response strategies. 1 Hayhoe, K., D.J.

What are the 10 impacts of global warming?Climate change is the single biggest health threat facing humanity. Climate impacts are already harming health, through air pollution, disease, extreme weather events, forced displacement, pressures on mental health, and increased hunger and poor nutrition in places where people cannot grow or find sufficient food.
What are three impacts of global warming?The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the duration and intensity of tropical storms.
What are the effects of global warming answer?Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. A warmer climate creates an atmosphere that can collect, retain, and unleash more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier.
