Detailed explanation-1: -Carbon dioxide is Earth’s most important greenhouse gas: a gas that absorbs and radiates heat. Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb heat radiating from the Earth’s surface and re-release it in all directions-including back toward Earth’s surface.
Detailed explanation-2: -Effects of climate change on forest processes Trees require light, heat carbon dioxide and water nutrient to grow through the process of photosynthesis. Increasing temperature, atmospheric carbon dioxide concentrations are altering photosynthesis rates and growth.
Detailed explanation-3: -Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years.
