PRESENTATION OUTLINE
What is climat change climate change is when the heat that is supposed to leave the atmosphere is unable to get out
How do we know its well as global climate change says The current warming trend is of particular significance because it is unequivocally the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over millennia.1 It is undeniable that human activities have warmed the atmosphere, ocean, and land and that widespread and rapid changes in the atmosphere, ocean, cryosphere, and biosphere have occurred.
Climate change can be caused naturally,or like the leading factors at the moment, human activity
Burning fossil fuels,releasing chemicals into the atmosphere reducing the amount of forest cover, and rapid expansion of farming development, and carbon dioxide into the atmosphere and changing the balance of the climate system
When we burn fossil fuels green house gasses are admitted into the atmosphere, causing something called greenhouse affects
The greenhouse effect is a process that occurs when energy from a plants sun goes through its atmosphere and warms the planets surface, but the gasses in the atmosphere keep the heat from escaping
The planets average surface temperature has risen about 2 degrees Fahrenheit since the late 19th century, a change driven largely by increased carbon dioxide emissions into the atmosphere and other human activity.
The Greenland an arctic ice sheets have decreased in mass data from NASA’s gravity recovery and climate experiment show Greenland lost an average of 279,000,000,000 tons of ice per year between 1993 and 2019, while Arctic lost about 148 billion tons of ice per year
