On December 12, 2015 192 countries sent representatives to Paris to discuss the pressing problem of climate change. The goal is to use more green energy sources to limit the rise in the global temperature.
The agreement addresses the problem of climate change, which must mean it is pretty important if there is a global meeting addressing the problem.
Cilmate.nasa.gov shares many reasons why our climate is changing.’’Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century’’.
“The planet’s average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.5 Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months.”
“The intensity, frequency, and duration of North Atlantic hurricanes, as well as the frequency of the strongest (Category 4 and 5) hurricanes, have all increased since the early 1980s. The relative contributions of human and natural causes to these increases are still uncertain.”
“Hurricane-associated storm intensity and rainfall rates are projected to increase as the climate continues to warm.”
“Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) everywhere are projected to become more intense, and cold waves less intense everywhere.”
“Summer temperatures are projected to continue rising, and a reduction of soil moisture, which exacerbates heat waves, is projected for much of the western and central U.S. in summer. By the end of this century, what have been once-in-20-year extreme heat days (one-day events) are projected to occur every two or three years over most of the nation.”
Countries can’t just switch from using fossil fuels to green energy overnight; they need the money. According to www.npr.com “To help developing countries switch from fossil fuels to greener sources of energy and adapt to the effects of climate change, the developed world will provide $100 billion a year,” they also said that money is a ‘’floor not a ceiling’’.
“It’s an acknowledgment that in the near future, total emissions of carbon dioxide and other greenhouse gases won’t fall — in fact, they’ll rise, as developing economies consume more energy.”
“But the plan assumes that greener technology, conservation efforts, and processes to remove greenhouse gases from the atmosphere will eventually allow emissions to decline instead of rise — and at that point, the “peak” will be achieved.”
Nations predict to see a “framework’ of the reductions to begin in 2020. That year is also the deadline for countries to submit a long term plan looking decades into the future.”
By 2020 the nations will look at their plans and see what needs to be done to be at the 2-degree target. The goal is to limit the temperature rise by two degrees C. ‘’Limiting the rise in temperature to 2 degrees (3.6 degrees Fahrenheit) has been discussed as a global goal for several years now. That amount of warming will still have a substantial impact, scientists say, but will be less devastating than allowing temperatures to rise unchecked’’. www.npr.com. “Targets must be submitted 9-12 months before they are finalized, creating time for other countries and civil society to seek clarity about the targets submitted,” the Obama administration wrote.
“Each target should reflect progress from the prior one, reflecting the highest possible ambition
that each country can achieve. This durable, long term framework will drive greater climate ambition as technologies improve and circumstances change.” by 2050 the goal is to have 0 greenhouse gasses. “Any greenhouse gases emitted would be balanced or zeroed out by removing an equivalent amount from the atmosphere. In the case of carbon dioxide, that would presumably be accomplished by growing forests, which absorb carbon dioxide.”
