The world's forests provide many important benefits to the world - more than half of all species living on land live in the world’s forests. Global climate changes and the world’s forests are inescapably linked, the negative effect of global climate change on the world’s forest affects the human beings biologically and socio-economically.
Global climate change is any significant change in measurements of climate such as temperature, pre¬cipitation, or wind. Leading indicators of Climate change is greenhouse effect where the atmosphere gases such as carbon dioxide traps solar radiation in the atmosphere. (Climate Change Indicators 1-2) Predicted by EPA as one of the greatest environmental challenges the world faces today. The global climate changing and the greenhouse effect are a result of human activity. If not slow down there will be dire consequences to the world.
The last several decades, evidence of human influences on climate change has become increas¬ingly abundant and clear. There is indisputable evidence that human activities such as the burning of hydrocarbons are adding to the concen¬trations of greenhouse gases and global climate change. 14 percent increase from 1990 to 2008 carbon dioxide accounts for most of the nation’s emissions. carbon dioxide emissions is not the only side effect of global climate change and also affects the temperature and weather of the earth Average temperatures have risen across the lower 48 states since 1901, with an increased rate of warming. Seven of the top 10 warmest years on record for the lower 48, states have occurred since 1990. Contrary to popular belief, global climate change is not the same as global warming because in global climate change there is also an increase for extreme weather. The intensity of tropical storms in the Atlantic Ocean, Caribbean, and Gulf of Mexico did not exhibit a strong long-term trend for much of the 20th century, but has risen noticeably over the past 20 years. Six of the 10 most active hurricane seasons have occurred since the mid-1990s. (Climate Change Indicators)
Healthy forests are essential yet forests, like other ecosystems, are subject to a number of threats. The causes of the negative impacts on forest health the impacts include, but are not limited to, fire, insects and diseases, overexploitation of wood products, poor harvesting practices, poor management, invasive species, air pollution and extreme climatic events i.e. drought, frost, storms and floods. (Climate Change Indicators 57) The consequences of global climate change can all be associated with the threats to forests ecosystem. The Health of forests is important not only for the animals inside the forest but us humans as well. An estimated area the size of Panama or Sierra Leone 7 million Hectares is loss per year. Climatic events such as drought, wind, snow, ice, and floods have always influenced forest ecosystems. However, global climate change, primarily the result...
