There is no Planet B — What is really the truth behind climate change warning?
There is no Planet B — What is really the truth behind climate change warning?
You probably heard about climate change, but what it does really mean for us and our planet for the foreseeable future?
Firstly, I will talk about the causes of climate change and the effects of greenhouse gases :
Human activates in modern history after the industrial revolution is the main cause of climate change, gases like CO2 and chlorofluorocarbons, and methane affect our atmosphere and that causes in increasing the sunlight, causing directly warming the earth.
the giant using of fuel & oil in factories and cars is the main cause of CO2.
Second, the effects of greenhouse gases and emissions on the earth:
According to NASA:
“The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the number, duration, and intensity of tropical storms. “
The Effects of Climate Change
› en español Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on…climate.nasa.gov
future impacts:
Sea levels are expected to rise between 10 and 32 inches (26 and 82 centimeters) or higher by the end of the century (2100) because the ice continues to melting especially at the Earth’s poles.
Hurricanes and other storms are likely to become stronger. Floods and droughts will become more common.
Less fresh water will be available since glaciers store about three-quarters of the world’s freshwater.
Some diseases will spread, such as mosquito-borne malaria (and the 2016 resurgence of the Zika virus).
Ecosystems will continue to change: Some species will move farther north or become more successful; others, such as polar bears, won’t be able to adapt and could become extinct.
Rising temperatures affect wildlife and ocean life and that causes a shortage of food.
Future regional impacts:
North America: Decreasing snowpack in the western mountains; 5–20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity, and duration of heat waves in cities that currently experience them.
Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture, and energy generation.
Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea-level rise; a glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.
Africa: between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions; agricultural production, including access to food, maybe severely compromised.
Asia: Freshwater availability projected to decrease in Central, South, East, and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions.
lastly, what can we do?
Honestly, it is too late to fix what we have done before, but we can protect the remaining of our Earth and photosphere and we can reduce these future effects.
What is the Paris Agreement :
The Paris Agreement is a legally binding international treaty on climate change. It was adopted by 196 Parties at COP 21 in Paris, on 12 December 2015 and entered into force on 4 November 2016.
Its goal is to limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.
To achieve this long-term temperature goal, countries aim to reach global peaking of greenhouse gas emissions as soon as possible to achieve a climate-neutral world by mid-century.
The Paris Agreement is a landmark in the multilateral climate change process because, for the first time, a binding agreement brings all nations into a common cause to undertake ambitious efforts to combat climate change and adapt to its effects.
What The Europe and USA have Done?
USA:
President Trump in 2017:
“The Paris Agreement handicaps the United States economy in order to win praise from the very foreign capitals and global activists that have long sought to gain wealth at our country’s expense. They don’t put America first. I do, and I always will.”
The USA withdrew from the PARIS agreement in 2017.
EUROPE :
The EU has set ambitious measures and goals to reduce its greenhouse gas emissions. It has done so by defining emissions targets for key sectors of its economy.
The 2020 Goal:
reducing greenhouse gas emissions by 20% (compared to 1990)
increasing the share of renewable energy to 20%
making a 20% improvement in energy efficiency
The EU is already ahead of these targets. By 2018, greenhouse gas emissions had been reduced by 23%, which is three percentage points above the initial 20% target
2030 Goal: net domestic reduction of at least 55% in greenhouse gas emissions.
2050 Goal: climate neutrality goal — zero emissions
Final thought :
We can defend our earth and environment by doing some steps in terms of using energy and food as well as raising awareness.
- we should reduce our using of energy and invest in renewable energy.
- reduce our using of fuel emission that comes from our cars, we can use public transport or environmentally friendly trains.
speak up: Encourage the Government to enact new laws that limit carbon emissions and require polluters to pay for the emissions they produce
