Climate Change can gulp 80 million jobs by 2030


Climate change can chew 80 million jobs by 2030. International Labour Organization (ILO) under United Nations projected the dreadful outcome based on their recent studies. The main reason is the increase in temperature.

A temperature rise of 1.5C by the end of century could lead to a 2.2 per cent drop in working hours – equal to 80 million full-time jobs – costing the global economy US$2.4 trillion, according to projections by the U.N. International Labour Organization (ILO).

“The impact of heat stress on labor productivity is a serious consequence of climate change, which adds to other adverse impacts such as changing rain patterns, raising sea levels and loss of biodiversity,” said ILO’s Catherine Saget.

The World Health Organization has said heat stress linked to climate change is likely to cause 38,000 extra deaths a year worldwide between 2030 and 2050.

Heat stress occurs when the body absorbs more heat than is tolerable. Extreme heat can cause heat-related illnesses, such as heat stroke and exhaustion, increase mortality, and exacerbate existing health conditions.

Agricultural workers – especially women, who make up the bulk of the 940 million laborers in the sector – will be most affected, the ILO said, accounting for about 60 per cent of all working hours lost due to heat stress by 2030.

If global temperatures rise as predicted, the construction industry will account for about 19 per cent of lost working hours, with the poorest countries in Southeast Asia and west Africa worst hit, the ILO added.

Facts proving that the climate change is real


By: Amrita Singh


Environmental change is real and that’s evident. It’s high time that we realise the need for our actions and take steps to combat the environmental changes.

Repercussions of environmental change is widespread. Recently a starving polar bear has strayed hundreds of kilometres from its natural Arctic habitat into the Russia city of Norlisk in Siberia. It is the first polar bear seen in the city in more than 40 years.

Over the past few years it has been observed that Arctic has been reportedly turning brown. This, reportedly, has been credited to the extreme temperatures the region faces.

When you think of snow the first thing that comes to the mind is a thick white sheet of snow covering the area. However it was reported that this winter due to the pollution in Siberia the snowfall wasn’t white it was black making it toxic.

7 environmental change facts you should know :-

• Sea levels are rising at their fastest rate in 2000 years.

• More greenhouse gases are in our atmosphere than any time in the human history.
• Climate change will lead to a refugee crisis.
• Two-thirds of the Great Barrier Reef has been damaged due to climate change.

• Earth could warm by 6 degrees this century.
• The PH of ocean surface water has decreased by 0.1, which makes them 26 percent more acidic now.
• The Arctic region may have its first completely ice-free summer by 2040.

Well, talking only about the problems is of no use, what is needed is quick action.

This year, The Deerfield Beach International Fishing Pier in Florida drew 633 divers. The Scuba divers gathered trash from the ocean floor and, in doing so, set a Guinness World Record for the largest underwater cleanup.

For the first time ever, UK uses more reusable energy than fossil fuels.

The school strike for climate (also known variously as Fridays for Future, Youth for Climate and Youth Strike 4 Climate) is an international movement of school students who are deciding not to attend classes and instead take part in demonstrations to demand action to prevent further global warming and climate change.

This shows that people are making efforts to combat environmental changes but more awareness and actions are needed. The greatest threat to our planet is the belief that someone else will save it.
So realise the wrong we are doing to the planet before it’s too late !

Friendly reminder:-

Eco-friendly materials for Refrigerators and ACs can counter climate change


Refrigerators and ACs are major cause of climate change due to its coolants. The recently discovered materials, published in Nature Communications journal, can replace the traditional coolants and give another chance for humans to fight climate change.

When put under pressure, plastic crystals of ‘neopentylglycol’ yield huge cooling effects- enough that they are competitive with conventional coolants. In addition, the material is inexpensive, widely available and functions at close to room temperature.

The gases currently used in the vast majority of refrigerators and air conditioners- hydrofluorocarbons and hydrocarbons (HFCs and HCs) – are toxic and flammable. When they leak into the air, they also contribute to global warming.

In the study, researchers described the enormous thermal changes under pressure achieved with plastic crystals.

Conventional cooling technologies rely on the thermal changes that occur when a compressed fluid expands. Most cooling devices work by compressing and expanding fluids such as HFCs and HCs. As the fluid expands, it decreases in temperature, cooling its surroundings.With solids, cooling is achieved by changing the material’s microscopic structure. This change can be achieved by applying a magnetic field, an electric field or through mechanic force.

Oceans will be bluer and greener in color in 2100, thanks to climate change


Climate change is not only increasing the sea level but will also change the color of the ocean by 2100. A new study by Massachusetts Institute of Technology (MIT) found the relation between color and climate change. The color won’t be extremely dramatic and hardly noticeable by the human eye but the change is real.

The warming planet is changing the distribution of phytoplankton across the world’s oceans. It’s well-known that seasonal changes regularly change colors, bit warmer oceans may permanently alter the mosaic of blues and greens as seen from space. In subtropical regions, warm waters will get even warmer, driving out phytoplankton populations and even marine life, in general. In water closer to poles, the warming will make the water appear greener while in subtropical regions, it will appear bluer.

“These microscopic organisms live in the water and are the base of the marine food chain,” said Stephanie Dutkiewicz, a marine ecologist at the Massachusetts Institute of Technology and the leader of the study, published Feb. 4 in the journal Nature Communications. “By being in the water, they change the color that we see by eye. If there are less of them in it, the water will be slightly bluer.”

Phytoplanktons are very small plants residing in the water bodies. They provide food for the fishes and other sea animals. They are the food chain initiator in the water bodies.  Scientists have found that climate change will likely alter the types of phytoplankton that abound in future oceans.

For their research, Dutkiewicz and her colleagues developed a computer model that simulated changes in the world’s climate from 1860 through 2100. The model assumed that global temperatures would rise by 3 degrees Celsius — which is what most scientists think will happen if no effort is made to curb greenhouse gas emissions. The simulations, which take about three weeks to run on a large array of computers, revealed we can expect our oceans to look a little different in the future.

Climate change is real though many of our leaders don’t want to believe it. This effect of the color change is a little trivial but the main issue is the decline in the population of phytoplankton. They initiate the marine food chain and without them, the sea animals would die. Let’s hope we save that the conservative estimation of 3 degrees Celsius rise doesn’t become the reality.

After Antarctica, Greenland’s ice is also melting faster than predicted


In the recent study published in the journal Proceedings of the National Academy of Sciences says that climate change is causing Greenland’s massive ice sheets to melt much faster than previously thought. Just a week ago, it was revealed that the ice shelf at Antarctica is melting faster than in the 1980s.

According to the study, the ice sheet of Greenland is melting four times faster than in 2003. The ice sheet is melting due to continued and accelerating warming of the Earth’s atmosphere. This may lead to a faster rise in the sea level.

In another study, published last month in the scientific journal Nature, found that Greenland’s ice sheets which contain enough water to raise global sea levels by 23 feet. These ice sheets have been melting at an “unprecedented” rate, 50 percent higher than pre-industrial levels and 33 percent above 20th-century levels.

We need to worry about the rising level of the sea as 40 to 50 percent of the planet’s population lives in areas which are vulnerable to rising seas and eight of the Earth’s 10 largest cities that are near the coasts.

The study also found that the largest sustained ice loss from early 2003 to mid-2013 came from Greenland’s southwest region, which is mostly devoid of large glaciers.

“Whatever this was, it couldn’t be explained by glaciers, because there are not many there. It had to be the surface mass – the ice was melting inland from the coastline,” said Michael Bevis, a professor at The Ohio State University in the US.

That melting, which researchers believe is largely caused by global warming, means that in the southwestern part of Greenland, growing rivers of water are streaming into the ocean during summer.

It seems like humanity may have passed the point of no return when it comes to combating climate change. The only thing we can do is adapt and mitigate further global warming. It is too late for there to be no effect. The doomsday clock is ticking.

Global Warming: Oceans are heating faster than before


The world’s oceans have absorbed 60 percent more heat than previously thought over the last quarter of a century, scientists said Thursday, leaving Earth more sensitive still to the effects of climate change. Oceans cover more than two thirds of the planet’s surface and play a vital role in sustaining life on Earth.

According to their most recent assessment this month, scientists from the Intergovernmental Panel on Climate Change (IPCC) say the world’s oceans have absorbed 90 percent of the temperature rise caused by man-made carbon emissions. 

But new research published in the journal Nature used a novel method of measuring ocean temperature.

It found that for each of the last 25 years, oceans had absorbed heat energy equivalent to 150 times the amount of electricity mankind produces annually.

That is 60% higher than what previous studies showed.

While those studies relied on tallying the excess heat produced by known man-made greenhouse gas emissions, a team of U.S.-based scientists focussed on two gases found naturally in the atmosphere — Oxygen and carbon dioxide. 

Both gases are soluble in water, but the rate at which water absorbs them decreases as it warms. By measuring atmospheric oxygen and CO2 for each year, scientists were able to more accurately estimate how much heat oceans had absorbed on a global scale.

“Imagine if the ocean was only 30 feet (10 metres) deep,” said Laure Resplandy, assistant professor of geosciences at Princeton and lead study author.

“Our data show that it would have warmed by 6.5 degrees Celsius (11.7 degrees Fahrenheit) every decade since 1991.”

That compares with a IPCC estimate of a 4.0 C rise each decade.

Resplandy said the data showed mankind must once again revise down its carbon footprint, with emissions needing to fall 25 precent compared to previous estimates.

“The result significantly increases the confidence we can place in estimates of ocean warming and therefore helps reduce uncertainty,” said Ralph Keeling, a geophysicist at the University of California-San Diego and co-author of the study.

The IPCC warns that drastic measures need taking in order to limit global warming to 1.5 Celsius by the end of the century but the world produced a record amount of carbon emissions in 2017.
