photosynthesis and the effect of global warming by Alba Serrano on Prezi
Global warmingEarth's plants are countering some of the effects of climate change. More photosynthesis means a slower rise in carbon dioxide. Soil organic matter decomposition rates are likely to be stimulated by higher temperatures, so that nutrients can be more readily mineralised and made available. More than half of photosynthesis taking place on the earth surface occurs in Today, the growing threat of global warming is becoming more and more vivid. . Firstly, two questions should be answered: 1) What affect can global warming cause . is necessary to consider the relationship between light and nitrogen impact.
How Plants Could Impact Global Warming
The "ozone hole" refers to the destruction of a layer of ozone molecules found high in Earth's atmosphere.
When healthy, this ozone layer helps to shield Earth from the sun's harmful ultraviolet rays. The ozone layer has become thinner because of chemicals called chlorofluorocarbons that were once commonly used in products ranging from spray cans to foam furniture cushions.
A thinner ozone layer allows more ultraviolet rays to reach Earth, increasing the risk to humans from skin cancer, cataracts, and other health impacts. This, however, has only minor effects on climate change.
Will a small rise in sea level affect people even in the United States? A small rise in sea level will affect many people, even in the United States. Without adaptation, coastal flooding and land loss will affect and displace hundreds of millions of people around the world by the year Global sea level has risen approximately 7.
This rise has already put coastal communities and infrastructure at risk, including water supply and energy infrastructure; evacuation routes; ports, tourism, and fishing sites; communities; and ecosystems. By the yearsea level is projected to rise another one to four feet. For example, a sea level rise of two feet, without any changes in storms, would more than triple the frequency of dangerous coastal flooding throughout most of the northeast United States.
Flood waters can damage homes, disrupt energy, communications, or transportation systems, and create health hazards during and after floods. Other observations that point to higher global temperature includes: It is not too late to have a significant impact on future climate change and its effects on us.

With appropriate actions by governments, communities, individuals, and businesses, we can reduce the amount of greenhouse gas pollution we release and lower the risk of much greater warming and severe consequences.
Many of the actions that we can take to address climate change will have other benefits, such as cleaner, healthier air.
In addition, communities can take action to prepare for the changes we know are coming. Climate Change Impacts in the United States: The Third National Climate Assessment.

The most common fossil fuels include coal, natural gas and fuel oil.
Climate Change Facts: Answers to Common Questions
Energy production, transportation and industrial activity all contribute significantly to the emission of carbon dioxide and other greenhouse gases. Photosynthesis Plants convert carbon dioxide and water into sugar and oxygen through the process of photosynthesis. Plants absorb carbon dioxide from the atmosphere during photosynthesis. A small amount of carbon dioxide is released during leaf respiration intake of oxygenbut it is quickly reabsorbed during photosynthesis. So, most carbon dioxide absorbed during photosynthesis is kept out of the atmosphere until the plant dies.

Trees and other plants store carbon and significantly reduce the amount of carbon dioxide in the atmosphere. Plants in tropical regions have the greatest impact on the greenhouse effect.
Because they get more sunlight than plants in temperate and sub-polar regions, they photosynthesize more.
