Scientists are now concerned that the greenhouse gases are being increased by human actions to levels that could be very harmful to life on Earth. Almost all specialists agree that without drastic steps to curb greenhouse gas emissions, the average global temperature will increase 1 to 3.5 degrees Celsius during the next century because effective levels of carbon dioxide are expected to double sometime between 2050 and 2100. Many of the greenhouse gases remain in the atmosphere for a long time, and because this happens their tendency to warm the Earth persi... ... middle of paper ... ...eforestation of previously forested land that has become agriculturally useless has to be promoted. That will require conservation incentive schemes and improvement of farm yields to reduce the pressure to clear new land. This will not be nearly as expensive as coping with the costs of global warming.

I was amazed at this educated response from my interviewee. The fervor and immense amount of knowledge on the topic that Adam displayed was amazing to me. It scared Adam, as it did me, that even politicians so readily discount scientific evidence. Adam went on to say that “the carbon dioxide we emit today will probably affect the climate well into our children’s future and likely into the future of our grandchildren.” Despite the widespread recognition of this fact, worldwide emissions of fossil fuels continue to increase every year.
Increasing sea levels, irregular temperatures, melting glaciers, extinction of species, and warmer oceans are only a few signs that worldwide climate is changing. The National Oceanic and Atmospheric Administration (NOAA) explain that "climate is the 'average weather' over a period ranging from months to thousands or millions of years." NOAA goes on to define Abrupt Climate Change as "a change in the climate (for example, in temperature or precipitation) that takes place over a few decades or less, persists for at least a few decades, and causes substantial disruptions in human and natural systems" (NOAA 1). Excess greenhouse gases in Earth’s atmosphere are leading to rapid climate change in the form of global warming and are irreparably harming plants, animals, and people. Some consequences of global warming - such as severe heat waves and stronger hurricanes - can be life-threatening.
This was the reality for millions of people during Hurricane Katrina. How safe would you feel knowing that natural disasters such as this may not only increase in frequency, but intensity as well? II. Establish Credibility – As Al Gore, the Nobel Peace Prize winner for his work on climate change, once said, “What changed in the United States with Hurricane Katrina was a feeling that we have entered a period of consequences.” These consequences include the earth warming 2 to 3 degrees in the next century, arctic ice disappearing completely, and coastal flooding.

Global Warming is used by scientifically people and is usually meant as a bad thing, that the earth is changing for the worse. On the contrary, Climate Change is used by the hoax believes on the most part. They use it in the way that the Earth is experiencing change that is normal because the climate will change year by year and always will change. Every day people who do not have research behind their claims are the ones who think it is a hoax. The average person is unable to collect enough reliable information to tell for sure what is correct or not.

The impacts are already happening around us and are likely to impact fresh water resources, food, coastal systems, and natural ecosystems. Animals and plants have already begun to change the way they live, yet vulnerable, and if no action is taken may leave us horrified results. Yes we need to continue to hold industries accountable for their greenhouse emissions slowing down global warming but we cannot stand on this decision alone.
Controversial Sciences: Global Climate Change Climate change has become a very sore subject for many scientists all around the world. There are some people that believe climate change and global warming are just a simple myths for gullible people, that humans have no affect at all on how our environment is changing. On the other hand, it is also told that 97% of papers taking a side on global climate change caused by humans agree that it is happening (Wayne). Many people read the evidence and can clearly see that humans are causing climate change not only to speed up but cause so many things to change in our environment as a result of it. Climate change is the change in the climate patterns of the Earth causing the atmosphere to heat up that became known in the 20th century.
Earth’s climate has always warmed and cooled. These temperatures are normal and natural and have happened for the last three thousand years. “Rising levels of atmospheric CO2 do not necessarily cause global warming, which contradicts the core thesis of human-caused climate change” (Moore). There is little evidence that proves that CO2 is the direct cause for global warming. More than half of the human emitted CO2 has already been re-absorbed by the earths carbon sinks.
Is global warming still a problem today? Global warming will forever be occurring around the world. Michel Jarraud, from the World Meteorological Organization, has mentioned the remember-able hot summer from 2012 to 2013 in Australia and the freezing winters in the US, Europe, Russia, and China. Larry Vardiman has states for the past 50 years there has been an increase in carbon dioxide in the air. Also, the sea temperature, occurrence of hurricanes, and melting of ice-burgs have been increasing.
