Climate change and global warming are hot topics these days. Studies conducted by various scientists suggest that climate change is happening and it could have devastating and damaging effects on human life. So, what is climate change?
Climate change is a change in the usual weather found in a place. This could be a change in how much rain a place usually gets in a year. Or it could be a change in a place's usual temperature for a month or season.
Climate change is also a change in Earth's climate. This could be a change in Earth's usual temperature. Or it could be a change in where rain and snow usually fall on Earth. Weather can change in just a few hours and climate takes hundreds or even millions of years to change.
Climate Change facts
Climate change facts show clearly that we need to act. Change is happening; the Paris Agreement set the ball in motion – though has been criticised for not going far enough –; and as well as nations including Portugal, Denmark, Costa Rica and Scotland producing huge amounts of energy from the sun and wind; Sweden is soon set to become the first fossil fuel-free country in the world; largely due to public demand in the past few years.
The effects of climate change has already started occurring in the form of melting of polar ice caps; rise in sea level, stronger storms, extinction of species; Here are some 41 facts of climate change to start you off.
#1- The Arctic region may have its first completely ice-free summer by 2040
Glaciers all over the world - in the Alps, Rockies, Andes, Himalayas, Africa and Alaska - are melting and the rate of shrinkage has increased in recent decades. In less than 30 years, the polar bear playground in the Arctic may no longer have any ice.
Researchers have been using computer models to simulate climate change, specifically to analyze how global warming could impact sea ice. In 2017, arctic sea ice reached a record low for the third straight running, according to scientists from the National Snow and Ice Data Center (NSIDC) and NASA.
According to a new study published in Geophysical Research Letters, if greenhouse gases continue to get pumped into the atmosphere at the current rate, the majority of the Arctic basin will be ice-free in September by 2040.
#2- We Already Passed The Earth Overshoot Day
The Earth Overshoot Day, it is the day where humans have used up their allowance of natural resources that Earth can replenish in one year. The Earth Overshoot Day measure has been calculated since 1986 and the day has never fallen so early as in 2017. It looks at the balance between global footprint - what humans take from the earth - and biocapacity, which allows us to produce resources and absorb our waste.
Those resources are specifically, clean water, soil, clean air, carbon sequestration, etc. For 2017, that day was Aug. 2 according to the Global Footprint Network, which not surprisingly comes earlier than it did last year. That means from Aug. 2 until Dec. 31 humans are using resources that will not be replenished.
#3- Million species face potential extinction as a result of disappearing habitats
Due to global warming, over a million species may face extinction in the coming decades. Some animals require specific habitats; and many of these may go the way of the dodo as their ecosystems begin to fall apart. The most particular species at risk are those whose habitats will completely disappear or who are particularly specialised in what they eat or where they live. That could even include animals like the koala bear.
We have already lost 27% of the world’s coral reefs, and if present rates of destruction continue; 60% of the world’s coral reefs will be destroy in the next 30 years alone. Coral reefs are home to more than 25%; of all known marine fish species and occupy less than 1% of the marine environment.
#4- Average global sea level is expected to rise 7 – 23 inches before the end of this century
The sea levels have risen twice as much in the past 10 years as they did in the whole of the 20th century. By 2030, the number of people impacted by global flooding could triple. The number is currently 21 million, but that’s expected to increase dramatically since warmer air has the ability to hold more water vapor. The economic cost of flooding could be as high as $484,936,900,000 within the next 15 years.
#5- Climate change will lead to a refugee crisis
Displacement of people as a direct result is not a hypothetical, it's already happening. An average of 21.5 million people have been forcibly displaced since 2008 due to climate change-related weather hazards, according to the United Nations High Commissioner For Refugees. The organisation says that climate change also acts as a 'threat multiplier' in areas of ongoing conflict. "Climate change sows seeds for conflict, but it also makes displacement much worse when it happens", it says.
#6- Diseases and plagues are expected to increase by 2100
For thousands of years; humans have taken every precaution to avoid mosquitoes and the diseases they carry; from Malaria to Zika. But while techniques for fighting the insects have improved dramatically over time; scientists say long-term climate change could soon make protecting humans from mosquitoes much more difficult.
The link between climate change and mosquito-borne illness centers around how rising temperatures may expand the area in which mosquitoes can thrive. A 2013 study in the journal PNAS describes the "complex feedbacks" between climate and mosquito-borne illness as highly "location-specific." Some areas where policy makers have never had to worry about mosquitoes will likely face diseases unthinkable just decades ago. Other areas may become too hot for mosquitoes to thrive as they have in the past.
#7- So Far, 2017 Is 2nd-Hottest Year on Record
With the first six months of 2017 in the books, average global surface temperatures so far this year are 0.94°C above the 1950–1980 average, according to NASA. That makes 2017 the second-hottest first six calendar months on record, behind only 2016.
Now the first six months of 2017 have been 0.3°C hotter than 1998, despite the former having no El Niño warming influence and the latter being amplified by a monster El Niño. In 1998, there was also more solar energy reaching Earth than there has been in 2017. The culprit is quite clearly human carbon pollution. That’s how the first six months of 2017; despite lacking solar or El Niño ocean warming, can be hotter than 1998, and 2006, and every year before 2016.
In fact, research has shown that global surface temperatures are already rising about 20 times faster than Earth’s fastest natural climate change, during the transition in and out of ice ages. And unless we take serious action to cut carbon pollution, that rate will rise to perhaps 50 times faster than Earth’s fastest natural climate change.
#8- The Rising Murder Count of Environmental Activists
In 2016, at least 200 land and environmental defenders were murdered – the deadliest year on record. Not only is this trend growing, it’s spreading – killings were dispersed across 24 countries, compared to 16 in 2015. Global Witness previously named 2015 as the "deadliest year on record" for the killing of activists with 185 deaths across 16 countries reported - a 59 per cent increase compared to 2014 and the highest figure since the group began collecting data in 2002.
Its latest report, Defenders of the Earth, found that nearly four people were killed every week across 24 countries last year while campaigning to protect the environment. The report tells the stories of these activists and the threats they’ve faced. It highlights the courage of their communities as they stand up to the might of multinationals; paramilitaries and even their own governments in the most dangerous countries on Earth to be a defender.
Climate change is here and is real. These facts are the proof that we faced a major problem caused by our fault; and now we have to do something to fix it.
