The primary causes and the wide-ranging impacts: 3-36 of climate change. Some effects act as positive feedbacks that intensify climate change.. Climate change affects the physical environment, ecosystems and human societies. Changes in the climate system include an overall warming trend, more extreme weather and rising sea levels. These in turn impact nature and wildlife, as well as human rapid melting of glaciers and ice sheets, contributing to sea-level rise. huge declines in Arctic sea-ice. ocean warming. People's lives are also changing. For example, parts of East Africa The Rainforest Alliance breaks down the numbers for you—and explains our innovative approach to keeping forests standing. Among the many gifts forests give us is one we desperately need: help with slowing climate change. Trees capture greenhouse gases (GHGs) like carbon dioxide, preventing them from accumulating in the atmosphere and warming Climate change (or global warming), is the process of our planet heating up. Scientists estimate that since the Industrial Revolution, human activity has caused the Earth to warm by approximately 1°C. While that might not sound like much, it means big things for people and wildlife around the globe. Unfortunately, rising temperatures don't Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms. A third, much smaller contributor to sea level rise is a decline in the amount of liquid water on land—aquifers, lakes and Effects of Global Warming. Global warming is a problem because it can lead to extreme weather conditions, flooding due to rising sea levels, and resulting deaths, destruction, and displacement. In fact, the term "global warming" is misleading, because not all areas will experience uniform temperature rises and some areas will not warm at .
