Brace for extra-warm weather through 2022: study

Published

on

PARIS: Manmade global warming and a natural surge in Earth’s surface temperature will join forces to make the next five years exceptionally hot, according to a study published Tuesday.
The double whammy of climate change and so-called natural variability more than doubles the likelihood of “extreme warm events” in ocean surface waters, creating a dangerous breeding ground for hurricanes and typhoons, they reported in Nature Communications.
“This warm phase is reinforcing long-term climate change,” lead author Florian Sevellec, a climate scientist at the University of Brest in France, told the Media. “This particular phase is expected to continue for at least five years.”
Earth’s average surface temperature has always fluctuated.  Over the last million years, it vacillated roughly every 100,000 years between ice ages and balmy periods warmer than today.
Over the last 11,000 years, those variations have become extremely modest, allowing our species to flourish.
Manmade climate change — caused by billions of tonnes of greenhouse gases injected into the atmosphere, mainly over the last century — has come on top of those small shifts, and today threatens to overwhelm them.
Teasing apart the influence of carbon pollution and natural variation has long bedeviled scientists trying hey to quantify the impact of climate change on cyclones, droughts, floods and other forms of extreme weather.
Sevellec and his colleagues tackled the problem in a different way. First, they focused on the natural fluctuations that – for most climate scientists – are “noise” obscuring the climate change fingerprint.
Second, they used a streamlined statistical approach rather than the comprehensive climate models that generate most long-term forecasts.
“We developed a system for predicting interannual” – or short-term – “natural variations in climate,” Sevellec said.
“For the period 2018-2022, we found an anomaly equivalent to the impact of anthropogenic warming.”
Natural warming, in other words, will have about the same impact as manmade climate change over the next five years.
The likelihood of a marine heatwave or other ocean “warming events” is predicted to increase by 150 percent.
The new method – dubbed PROCAST, for PRObabilistic foreCAST – was tested against past temperature records and proved at least as accurate as standard models.
It can be run in seconds on a laptop, rather than requiring weeks of computing time on a super-computer.
“This opens of the possibility of doing climate forecasts to more researchers, especially in countries that don’t have easy access to super-computers,” Sevellec said.
The researchers intend to adapt their system to make regional predictions, and – in addition to temperature — to estimate rainfall and drought trends.
The Paris climate treaty calls for capping global warming at “well below” two degrees Celsius (3.6 degrees Fahrenheit), and 1.5 C if deemed feasible.
On current trends, however, Earth is on track to heat up by twice that much before the end of the century.

How to determine sacrificial animals’ health?

Published

on

MULTAN: The Livestock Department advised the people to take special care while purchasing sacrificial animals on Eid-ul-Azha as some precautionary steps are helpful in determining the health of sacrificial animals.
Most of the citizens visit the cattle market once a year, to purchase animals and they lack information about some very important features to determine their health. According to Livestock Department Focal Person Dr. Majid, people should get gloves and caps from staffers of Livestock Department before entering into cattle market for purchasing animals.
Citizens should carefully observe ticks or lice on hides of animals and in case they found ticks then they must manage anti-ticks spray or injections before purchasing.  Citizens should also check the sitting place of animals and monitor the urine and dung of animals. If they found urine and dung in the normal state then they should purchase the animal, he informed.
Dr. Majid further remarked that an animal should be alert and active in the movement, and he advised the people to purchase animals in daylight instead of night time because they could assess the health of animals easily.
There should be no swelling, inflammation or redness on the legs of animals.  Similarly, citizens should also minutely observe stains of diarrhea at any part of the animal body.
There should be no eye secretions, no marks of lesions or redness at any part of the body.  “If there are some eye secretions then it could be the sign of eye worms diseases in animals. Similarly, nasal discharge is also one symptom of trachea and lungs infections. The skin of animal should be bright  and dull skin indicates symptoms of dehydration in  animals.”
The official added that some cattle dealers used to sell female animals. The citizens should approach a team of Livestock Depart, which is present in all cattle markets, for pregnancy test of the animals.
“If a citizen purchase animal from a farmer instead of the cattle market  then he should call at Help Line 08000-9211 of Livestock Department  for determining the pregnancy test.”
Citizens should identify the special place in their homes for temporary accomodation of animals. It should be a vast, spacious and nature friendly environment, he maintained.
The animals should not be tied with an electric pole or near barbed wires. “Keep animals away from other animals so that they should not fight one another. It is often seen that citizens used to tie animals quite near and they start hitting one another.”
Children should not be allowed to bring their cattle on roads. Sometime, animals get out of control and start running on roads which could cause injury to animals or cause road mishaps, the official added.
Similarly, they should manage vehicles which could easily transport the animal from market to home.
It is observed that some farmers as well as citizens used motorcycles or cars for the transport of the small animals which cause injuries to animals as well as citizens.
To a query about precautionary measures to deal ticks if found on animals, the focal person informed that they had set up 21 pickets in Multan Division for anti-ticks spray on animals.
Three pickets have been introduced in district Multan, five in Khanewal, five in Lodhran and eight in district Vehari.  He informed that thousands of animals have been sprayed in these districts by officials of Livestock Department during last few days.
Dr. Majid also suggested citizens to approach professional butchers only for slaughtering of animals as immature and non-professional butchers damage animal hides which are not only loss of hide but also damage its exports returns.
Similarly, the hides should be kept in shopper after applying salt on it, he advised.  Sometime, hides are thrown in a corner of the house, which is not properly cleaned. If the hide is pulled along the ground instead of lifting it, then it damaged due to friction and sometimes dust particles mixed into it which also destroy the quality of hides, he concluded.
