Nasa says hole in ozone layer is shrinking

The hole in the ozone layer is continuing to shrink, particularly throughout this year, Nasa said on Tuesday.

"This depleted area of the ozone layer over the South Pole was slightly smaller than last year and generally continued the overall shrinking trend of recent years," the space agency said.

International efforts have been stepped up to remove the threat posed by the hole.

Nasa said the annual Antarctic ozone hole reached an average area of 23.2 million square kilometres between September 7 and October 13.

Ozone is a natural molecule made up of three oxygen atoms mostly found high above the Earth, where it acts as a shield against radiation and from the Sun's ultraviolet rays.

The causes of the hole were effectively tackled as a result of international co-operation known as the Montreal Protocol, an agreement struck in 1987.

The hole is known as the thinning of the ozone layer, first detected over Antarctica in the 1970s, that continued to deteriorate into the 1990s.

The cause of the damage was attributed by scientists to a number of man-made chemicals in the atmosphere, particularly chlorofluorocarbons (CFCs), which were used in sprays, foams, air conditioning and refrigerators.

Some businesses attempted to dismiss concerns over the ozone hole as nonsense.

“Over time, steady progress is being made and the hole is getting smaller,” said Paul Newman, chief scientist for Earth sciences at Nasa’s Goddard Space Flight Centre in Greenbelt, Maryland.

“We see some wavering as weather changes and other factors make the numbers wiggle slightly from day to day and week to week.

“But overall, we see it decreasing through the past two decades. The elimination of ozone-depleting substances through the Montreal Protocol is shrinking the hole.”

Freezer tips

Always make sure food is completely cool before freezing.
If you’re cooking in large batches, divide into either family-sized or individual portions to freeze.
Ensure the food is well wrapped in foil or cling film. Even better, store in fully sealable, labelled containers or zip-lock freezer bags.
The easiest and safest way to defrost items such as the stews and sauces mentioned is to do so in the fridge for several hours or overnight.

Other simple ideas for sushi rice dishes

Cheat’s nigiri
This is easier to make than sushi rolls. With damp hands, form the cooled rice into small tablet shapes. Place slices of fresh, raw salmon, mackerel or trout (or smoked salmon) lightly touched with wasabi, then press, wasabi side-down, onto the rice. Serve with soy sauce and pickled ginger.

Easy omurice
This fusion dish combines Asian fried rice with a western omelette. To make, fry cooked and cooled sushi rice with chopped vegetables such as carrot and onion and lashings of sweet-tangy ketchup, then wrap in a soft egg omelette.

Deconstructed sushi salad platter
This makes a great, fuss-free sharing meal. Arrange sushi rice on a platter or board, then fill the space with all your favourite sushi ingredients (edamame beans, cooked prawns or tuna, tempura veggies, pickled ginger and chilli tofu), with a dressing or dipping sauce on the side.

Four reasons global stock markets are falling right now

There are many factors worrying investors right now and triggering a rush out of stock markets. Here are four of the biggest:

1. Rising US interest rates

The US Federal Reserve has increased interest rates three times this year in a bid to prevent its buoyant economy from overheating. They now stand at between 2 and 2.25 per cent and markets are pencilling in three more rises next year.

Kim Catechis, manager of the Legg Mason Martin Currie Global Emerging Markets Fund, says US inflation is rising and the Fed will continue to raise rates in 2019. “With inflationary pressures growing, an increasing number of corporates are guiding profitability expectations downwards for 2018 and 2019, citing the negative impact of rising costs.”

At the same time as rates are rising, central bankers in the US and Europe have been ending quantitative easing, bringing the era of cheap money to an end.

2. Stronger dollar

High US rates have driven up the value of the dollar and bond yields, and this is putting pressure on emerging market countries that took advantage of low interest rates to run up trillions in dollar-denominated debt. They have also suffered capital outflows as international investors have switched to the US, driving markets lower. Omar Negyal, portfolio manager of the JP Morgan Global Emerging Markets Income Trust, says this looks like a buying opportunity. “Despite short-term volatility we remain positive about long-term prospects and profitability for emerging markets.”

3. Global trade war

Ritu Vohora, investment director at fund manager M&G, says markets fear that US President Donald Trump’s spat with China will escalate into a full-blown global trade war, with both sides suffering. “The US economy is robust enough to absorb higher input costs now, but this may not be the case as tariffs escalate. However, with a host of factors hitting investor sentiment, this is becoming a stock picker’s market.”

4. Eurozone uncertainty

Europe faces two challenges right now in the shape of Brexit and the new populist government in eurozone member Italy.

Chris Beauchamp, chief market analyst at IG, which has offices in Dubai, says the stand-off between between Rome and Brussels threatens to become much more serious. "As with Brexit, neither side appears willing to step back from the edge, threatening more trouble down the line.”

The European economy may also be slowing, Mr Beauchamp warns. “A four-year low in eurozone manufacturing confidence highlights the fact that producers see a bumpy road ahead, with US-EU trade talks remaining a major question-mark for exporters.”
