Beneath the seemingly infertile soils of the Western and Northern Cape lie the dormant seeds of more than 1,200 different species of wildflowers; waiting for the sun to rally against the winter chill. Towards the end of August and the beginning of September, when the days begin to warm, the seeds split open and send tender shoots skywards to bloom. And so, it is that the arrival of springtime in South Africa becomes marked by a spectacular event that transforms the otherwise drab and semi-arid landscape into an explosive cacophony of colour.
For a few precious weeks, places such as Darling, Clanwilliam, the West Coast National Park, Cedarberg, and, further afield, the Namaqua National Park, Kamieskroon, Port Nolloth, and Springbok become heavily carpeted with purples, oranges, yellows, and reds like thick brush strokes of oil paint. This spellbinding show by nature attracts people in the thousands from all over the country, as well as from abroad. But, for all their beauty and vivacity, the blooms are short-lived and as September passes, the spectacle wanes until the landscape is once again returned to its usual shades of browns, greys, and greens.
The Darling Wildflower Show 2019
The annual blooming of the wildflowers isn’t only celebrated by the local wildlife, which delights in the unusual abundance of food; several towns in and around the so-called “Cape Flower Route” also put on exciting festivals. And perhaps the best known and loved of these is the Darling Wildflower Show, which is held every year on the third weekend of September. This year, the 102nd instalment, it’s taking place on the 20th to the 22nd September and is set to be an extravagant affair; the perfect complement to a morning or afternoon spent admiring the spectacular wildflowers.
Here, visitors can enjoy attractions, such as craft and gourmet food markets, a beer tent, a mini-wine route, tractor-drawn wagon rides, veteran car and tractor shows, kids’ play park, live entertainment by local artists and musicians, conservation talks, and educational workshops for both adults and children. And, of course, when you’re not delighting in the food, tipple, entertainment, and enlightenment on offer, there is the remarkable Cape floral kingdom to admire.
Wildflowers bloom in gardens, fields, and along the roadside throughout the Western and Northern Cape but the best places to see them are those that are undeveloped and unspoiled. The West Coast National Park, Darling (both 1 hour’s drive from Cape Town), Clanwilliam (2 hours, 20 minutes), and the Biedouw Valley in the Cedarberg (3 hours, 20 minutes drive) are rewarding spots to travel to. However, getting the most out of your wildflower viewing requires more than just jumping in your car and driving to your destination.
The wildflowers are coaxed open by the warmth of the sun and so they are best viewed on warm, sunny days between the late morning (±10am) and late afternoon (±4pm). If the weather is poor or it’s too early or too late, the flowers will close to protect themselves from the cold and possible frost, and you won’t get the full visual effect. The wildflowers also angle their heads towards the sun, so it’s best to travel from north to south or from east to west along the flower route so that you keep the sun behind you and, therefore, the flowers open towards you.
A bucket list must for Capetonians and visitors
The annual blooming of the wildflowers is a truly magnificent show that every South African needs to see at least once in his or her lifetime. With the fun and flamboyant Darling Wildflower Show, and some of the most ostentatious floral displays as little as an hour’s drive from Cape Town, there’s every reason Capetonians and visitors should add this to their travel bucket lists!
In this cool video, we learn how black holes are created from the death of massive stars, leaving behind a collapsed star so dense and with such skull-crushing gravity that not even LIGHT can escape it! Here’s a cool fact… if you were floating towards a black hole, the atoms in your feet would accelerate towards it faster than the atoms in your head and so effectively, you would be instantaneously ripped apart. Fun!

It’s too bad that seawater is salty, because with a bit of sweet flavouring, everyone would have had access to unlimited slushy “Slurpee” a year ago, courtesy of Mother Nature!

The United States spent much of February of last year in the frigid grips of a record-breaking icy winter. Yet, in addition to the usual suspects, which include deep snow and biting winds, the cold would seem to have even won over the briny seawater of the north Atlantic Ocean. This video shows a series of images of ocean waves breaking on the shores of Nantucket in New England (northeast USA), only, there seems to be something distinctly different about these waves!
The photographer, Jonathan Nimerfroh, is an avid surfing enthusiast and on a trip to the beach, he noticed something odd about the horizon. As it turns out, the temperatures are so low in the area the water has begun to freeze and so, what we are looking at are giant slushy waves! These icy waves have also been aptly called “Slurpee waves”
The maximum temperature on the day these pictures were taken was at a teeth-chattering -7 degrees celsius (17 degrees Fahrenheit).
What’s truly amazing about this is that salt is known to lower the freezing point of water to well below zero degrees celsius. This is precisely why we throw salt over our driveways to prevent them from icing up. The fact that even the salty seawater in northeast United States began to freeze is testament to the uncharacteristically cold winter they had last year.
Whoever coined the title of this video is a genius: the second I clapped eyes on it, the inner depraved version of myself immediately demanded that I click on the link to find out more about Earth’s biggest and most mysterious holes. As it turned out, the video is quite interesting, albeit well-behaved. So, if you’re desperately trying to look busy and important while waiting for a date, or want to avoid that annoying dude from accounting during your lunch break, here’s a fabulous and educational 10 minutes well spent.

Ever wonder what the view of Mars would be if it were as close to us as our moon? Would it glow a belligerent red in our night sky and confuse moths the world over? How about Neptune: would it cast a seductive blue glow over the body of your lover as she lies recovering from a delicious round of rodgering? Now imagine Jupiter, our solar system’s largest planet with moons that are twice/thrice the size of ours… what would they all look like if they had to take the place of our moon, without cataclysmically affecting life on our planet? This video answers that question…

No, this is not a joke, although I’m not referring to the sprites of fairy tales…
A “sprite” is a whimsical name given to a particularly ephemeral upper atmosphere phenomenon that’s generated by lightning discharges in powerful thunderstorm clouds. Sprites are witnessed as whispy colourful flickering shapes above the thunderstorm clouds and in this video, we watch a team of storm-chasers in hot pursuit of these large-scale electrical discharges.
The things people do for science…

There’s something beautiful about a woman’s rage (not counting the tarts from Geordie Shore) and in no better way is this sentiment illustrated than by Mother Nature’s ire. As terrifying as it is to be at ground zero, from a safe distance, natural disasters are incredibly awe-inspiring and angry volcanoes deserve a top spot for making people go “ooooh” and “aaaaah” and “oh shit…”
Volcanoes are literal pathways from the Earth’s fiery guts to its crusty exterior. But the channels available for the molten rock and gas that spew forth are far too narrow to satisfy the sheer volume of indigestion within and the result is an immense build-up of pressure. The release of this pressure includes, but is not limited to, violent sprays of lava, devastating pyroclastic flows, stratospheric columns of volcanic ash, electrical storms, scalding gas and dust and Hiroshima-type explosions that not only dislocate millions of tonnes of solid rock, but have been reported to be audible many thousands of kilometres away from the point of origin.
Volcanoes have the potential to send species to extinction, yet at the very same time, they nourish the biosphere in an appreciable radius around them (volcanic ash is highly fertile). Volcanoes are magnificent and a wonderful example of how the surface of our planet is in a constant state of dynamism.
Where Not To Go On Summer Vacation
Volcanoes typically form at the convergent and divergent boundaries between the enormous shifting tectonic plates that comprise the Earth’s crust (see gorgeous image above). It is here that the seams of the Earth permit plumes of its molten interior to travel towards the surface. But as it was mentioned, the surface-bound transport of this material is anything but a six-lane highway. It’s more like a gravelly, pothole-ridden country road. The gas and molten rock that are trying to get from A to B encounter rigid rock and the cracks they exploit along their journey are incredibly narrow. A build-up of pressure results in a potentially explosive situation, so that when something finally gives, the results are disastrous for the local biology: human habitation included.
Volcanoes also form over features called “hot spots”, which don’t necessarily occur near plate tectonic boundaries (see diagram below). The Hawaiian Islands – all of them formed by volcanic activity in the middle of the Pacific Plate – are a prime example of this.
There are several scientific theories that seek to explain what hot spots are and a popular one is that they are upwelling intrusions of molten material (mantle plumes) that originate at the boundary between the Earth’s core and mantle. The exact depth of this varies, but the Hawaiian hot spot is estimated to be 3,000 km deep. That’s 9,842,520 ft. for those of you in ‘Merica.
There’s more to volcanology than your stock standard angry Earth pimple. Volcanoes come in many shapes, sizes and compositions. What happens at the surface – what we see and experience when volcanoes awake from their slumber – is dependent on a suite of factors and an especially important one is the composition of the magma that is trying to escape the lithified constraints of the crust.
Rock that is rich in silicates tends to form chunky, viscous slow-moving magma. This subset of liquid rock is in no hurry to go anywhere and tends to contribute to terrible congestion. It also has the particularly nasty habit of trapping gas, which is why things can get explosive. Since Hawaii is no stranger to seismic activity, its inhabitants have coined a word for this particular magma and it’s pāhoehoe.
At the other end of the spectrum, you get magma that doesn’t contain a lot of silicates, but is rather rich in ferrous (iron) compounds. This magma – ʻAʻa, pronounced “ah ah” – get’s extremely hot and tends to flow hard and fast. If you’ll excuse the crass analogy, the difference between pāhoehoe and ʻAʻa is much like the difference between constipation and Delhi belly.
Both, however, are extremely uncomfortable.
Magma isn’t, of course, one or the other. There is a vast spectrum of mineral compositions between, but by understanding the difference between one extreme and the other, we can begin to understand how different kinds of volcanoes are formed.
Cone, Shield and Stratovolcanoes
If there’s one thing to be said for geologists, it’s that they don’t mess around with terminology. The name bestowed upon a volcano is as transparent as a wet T-shirt.
Cone (Cinder) Volcanoes
Cone volcanoes, also known as cinder cones, generally consist of a hill that can be anywhere from 30 meters (98 ft.) to 400 (1,312 ft.) meters in height. Formed from the eruption of materials that are riddled with gas, crystals and a hodgepodge of fragmented rock. To see an example of this kind of volcano, put on your sombrero, crack open the tequila and get on a plane to New Mexico. There, you will find a spectacular volcanic field called Caja Del Rio, which comprises more than 60 cone volcanoes. If the prospect of New Mexico doesn’t appeal, you can always bum a lift on the next scientific mission to Mars or the moon, both of which are believed to feature this type of volcano.
Shield volcanoes have a much broader profile than cone volcanoes and, as the name suggests, are shaped like shields. Bet you didn’t see that one coming. These beasts are formed from the eruption of very runny lava that tends to escape the Earth’s crust before causing too much mayhem as a result of a build-up of pressure. Shield volcanoes are, by comparison, the placid elderly aunt of volcanoes and are most commonly found at oceanic tectonic boundaries. Oceanic plates aren’t usually rich in silicates, which explains why the magma produced here is more felsic in composition, hence its lower viscosity. Skjaldbreiður in Iceland (say that three times fast) is an example of a shield volcano. The Hawaiian Islands, which have formed almost smack bang in the middle of the Pacific Plate over a “hot spot,” are also shield volcanoes.
Stratovolcanoes, or composite volcanoes, are the tri-polar member of the volcanic family. They look like your typical volcano but actually consist of alternating layers of different kinds of erupted material as the above diagram depicts. Stratovolcanoes produce a range of eruptions depending upon their mood and these include chunky cinders, choking ash and molten rock (lava). One of the best known (and least loved) of these volcanoes is Mount Vesuvius, which is located in Stromboli, Italy. This one was responsible for the notorious levelling of the cities of Pompeii and Herculaneum in AD 79, killing 16,000 people. It is estimated that Mount Vesuvius released 100,000 times the energy liberated by the Hiroshima bomb.
When volcanoes become active, a number of things can happen, none of them good if you’re fond of life. One of the most devastating of these consequences is ash. You wouldn’t think so… ash is soft and white. How on Earth could it possibly inconvenience you the way a searing hot lake of lava might? Stratovolcanoes are especially fond of explosive eruptions, which send voluminous clouds of ash into the atmosphere and cascading down their slopes.
This ash, however, isn’t the kind you find in your barbeque pit after a night of camping, beer and sing-a-longs. It’s mixed with gas that is hot enough to disassociate your atoms. These eruptions send roiling clouds of gas, dust, ash and other debris down the mountain, which devastate anything organic in their path, leaving behind a scene that looks like a bomb went off in a cocaine factory.
Extinct, Dormant and Active Volcanoes: The Good, the Bad and the Ugly
Volcanoes are dangerous creatures. So an apt analogy for the popular classifications of these geological features would be your mother. When she has a gin and tonic in her hand (dormant), you may want to make plans for the evening. When she’s 10 G&T’s down (active), it’s time to execute those plans and get the hell out of the house. When she’s passed out on the couch (extinct), it’s safe to come home, although my recommendation to you would be to move out your childhood home and get yourself an education.
Extinct volcanoes, such as the Netherland’s Zuidwal and Shiprock volcanoes, are no longer considered to be active at all because they don’t have a supply of magma. They also have no documented history of indigestion. Dormant volcanoes, on the other hand, are known to have erupted at some stage in recent history. They may be quiet, but that doesn’t mean they can’t suddenly awaken. Mount Vesuvius (Gulf of Naples) was a purring kitten before it went psycho in AD 79, as was Mount Pinatubo (Philippines) prior to its epic tantrum in 1991. The latter is now considered an active volcano, which is one that has exhibited recent activity and is therefore a potential hazard to all within its vicinity.
If you’ve ever had a fight with Mexican food and lost (who hasn’t?) then integrating “Krakatoa” into your vocabulary is a wonderful idea if you need help explaining exactly what just happened to you to the flat mate who is next in line for the bathroom. You may not be absolved for your sins, but it’ll get you a laugh or two.
Krakatoa is a first class example of what happens when Mother Nature gets really cross and decides to let off a bomb that makes Hiroshima look like a fart. In 1883, the build-up of pressure under the Earth’s crust between the islands of Sumatra and Java in the Sunda Strait was so immense that it caused an apocalyptic-sized explosion, sending a once much bigger island into the stratosphere.
The Krakatoa eruption was reported to have been heard almost 5,000 km away (the loudest sound ever made in recorded history) and the resultant shock waves sent barograph needles oscillating violently off the page. Over 36,000 people were killed by the eruption: if not by the devastating pyroclastic flows and falling debris, then by the tsunamis that followed. The dust catapulted into the atmosphere caused stunning sunsets around the world for months after the eruption.
Too bad colour photography wasn’t in vogue in the 19th Century.
Class Dismissed: Your Take-Home Message
If you ever needed to respect the fact that we are just not in control of our natural environment, then stand next to an active volcano. From lakes of lava and earthquakes that shake the foundations of your stick hut to falling debris and scalding hot pyroclastic flows that choke the biosphere, volcanoes are creatures to be respected, studied and understood. If ever there were an item to put on your bucket list, it would be to stand next to an active volcano and feel the heat of Earth’s exterior lap at your cheeks. Just make sure you’ve ticked off the rest of those bucket list items before you do so…
It took two long haul flights, six plastic wrapped airline meals, three movies, two cantankerous airhostesses and a dangerous brush with halitosis for me to learn about the latest crisis throwing a spanner in the works of the mankind’s (mostly shoddy) attempts to run things smoothly on planet Earth.
I’m talking, of course, about El Niño.
I had to come to Los Angeles to learn that we’re actually teetering on the edge of what the western media is referring to as a “monster El Niño event” and by the time I publish this, we may very well have taken the dive. Where I come from – South Africa – the media and moreover the government pay scant attention to weather and climate issues. This is extremely ironic considering our economy is based on primary industry and that El Niño years are linked with drought in Southern African’s interior. So, in keeping with this relationship, we’re currently facing critical drought conditions for which the government has done nothing to prepare.
Alas! Here in South Africa, the government is far too distracted by President Zuma’s antics in and out of parliament and the country’s courtrooms to worry about the fact that our crops are about to shrivel up faster than Zuma’s manhood when it was explained to him that showering after intercourse does not in fact prevent the transmission of HIV. And unfortunately, they would also rather spend taxpayers’ money on private jets, fancy cars and extravagant lifestyles for its unprecedented number of officials than on research into, and mitigation for climate change and global climate phenomena like El Niño. If you were a selfish, uneducated pack of pricks, wouldn’t you too?
Anyway, that is where my political rant ends. The point is this: I only recently learned that the planet is facing the meanest El Niño event since 1997 and is set to become one of the three strongest on record, like, ever. It’s already causing all kinds of interesting weather anomalies across the world, especially in the United States. So, it’s time for a new blog in which we’ll meet “the boy” wreaking an incredible amount of wanton mischief on our biology, biomes and backyards.
Who Is This “Boy” And Why Does He Mischief Thusly?
El Niño refers to the periodic, unusual warming of the ocean waters of the central and eastern equatorial Pacific and it’s named “the boy” in Spanish after the baby Jesus, since it typically occurs around Christmas time. Understanding why El Niño has such extensive impacts upon weather requires us to take a closer look at a very important variable (sea surface temperature) as it usually is versus what it becomes when El Niño buggers around with ocean and atmospheric circulations. And so, the instigator of it all – the key player I need to introduce you to first is…
The Easterly Trade Winds!
Image Source: mrspruillscience.weebly.com
Over the tropical Pacific Ocean, in other words around the equator, the trade winds blow roughly from east to west (see diagram above). Now, wind may seem like nothing more than moving air until your house gets relocated by a tornado; only then do you realize it’s a force to be reckoned with! So, the effects the northeast and southeast trade winds have on the ocean surface in the equatorial Pacific are quite significant.
The easterlies exert a force on the warm surface water, pushing it and causing it to pile up in the west, so much so that there is actually a 500-milimetre difference in sea surface height between Indonesia (west) and Ecuador (east)! This does a few things:
With the warm surface waters being piled up in the west, an 8°C temperature difference is created between the eastern and western equatorial Pacific, with the west being beautifully toasty. A warm ocean surface makes for a sexy, moist atmosphere and the result is a lot of rainfall. This is why Indonesia is beautifully lush.
On the other side of the Pacific, the wind pushing the surface waters away from the South American coast causes cold water from depth to rise to the surface (upwell), thereby leaving the ocean here chilly enough to embarrass you if you were dude wearing a speedo swimsuit. And, of course, the air overlying a cold ocean is typically dry and promotes little rainfall.
Ocean upwelling is a really important process, so it deserves a little conversation before we continue. When ocean creatures and critters die, their bodies sink, making the waters at depth wonderfully fertile. The upwelling of this water to the surface brings all this organic matter into the glorious sunshine and this leads to a surge in primary productivity. Of course, with great volumes of delicious algae, plankton and other tiny sea squishies available, every critter in the food chain is given the energy influx it needs to prosper, which essentially means lots of rodgering, lots of babies and lots of biological success. It also means lots of sushi for us.
So, we have a warm western equatorial Pacific with a rainy atmosphere and a cool eastern equatorial Pacific and a dry atmosphere. That’s the way it USUALLY is with the northeast and southeast trade winds happily blowing.
However: every two to seven years – and there doesn’t appear to be any strict rhyme or reason as to the frequency of this – the normally healthy trade winds stagger and weaken and you would scarcely BELIEVE the cluster f**k of consequences that follow.
A Specific Account of the Cluster of F**ks That Follow
With the easterly trade winds fizzling out, all the beautifully warm water that is usually swept to the west is allowed to slough back into the east. This causes a tongue of warm water to spread out from the western coastline of North America (see diagrams below).
A key point you must remember is that the ocean and atmosphere seldom, if ever, act independently of each other. One minor change in sea surface temperature can cause the atmosphere to overreact like your girlfriend approximately one week before Aunt Flo arrives for her monthly visit. A warm sea surface leads to greater evaporation, a more humid atmosphere and therefore more rainfall.
So, with ocean heat draining from the usually wet western Pacific, the region is typically left in drought while the east, which is usually dry, becomes unusually wet. On the ground, Indonesia and Australia can experiencing drought and, in Australia’s case, a much greater risk of catastrophic bush fire. On the eastern side of the Pacific, where the ocean has become anomalously warm, unusually heavy rainfall can lead to flooding with the risk being greatest to the southern states of America and Peru.
The weakening of the trade winds also negatively affects the upwelling that usually occurs off the western coast of South America and by throttling the source of nutrients these marine ecosystems rely on, organisms of all echelons in the food chain take a major blow. Less importantly (in the grand scheme of things – don’t tell any local fisherman I’m saying this) our fishing industries also suffer. That’s right: less sushi.
If you thought that’s where it ends, think again. El Niño’s impacts spread further than a desperate housewife’s legs. The accumulation of vast reservoirs of heat energy at the eastern periphery of the equatorial Pacific drive significant changes in global atmospheric circulation, which essentially means that no matter where in the world you live, you can possibly expect the next few months’ of weather to be, uh… interesting.
Crappy Weather Coming To a Neighborhood Near You
Air in the atmosphere is constantly on the move and it’s thanks to our major global atmospheric circulations that all the crap going down in the Pacific is felt in varying degrees across the globe. Here are some cherry-picked samples of other global consequences:
El Niño events are linked with wilder hurricane seasons in the Pacific. This is terrible news for the Philippines, which is already one of the most disaster-struck countries in the world. According to Colorado State University, there have been 21 Category 4 and above (read: holy crap that’s big!) hurricanes in the north Pacific this year alone. This total has obliterated the previous record of 17, which was set during the monster El Niño of 1997. The good news for Florida and southern Texas is that hurricanes in the Atlantic tend to stay home and pursue their hobbies during El Niño months.
Africa may be half the planet away, but the continent has a decent sized serving of interesting weather to expect. Southern Africa is currently in the throes of severe drought, while several East and North African nations are being pelted by heavy rainfall. I mean, can’t we ever just get the RIGHT amount of rain?? Why must it be one extreme or the other?
And, of course, we can’t leave out the main character in this story of wanton weather: MURICA! The following prediction maps for temperature and rainfall have been issued by the National Ocean and Atmospheric Administration (NOAA) on their amazing website, which you can view at www.climate.gov.
What we can tell from this map (aside from the fact that NOAA doesn’t give a hoot about Canada) is that there is a good chance of temperatures being hotter than usual in much of Alaska, Washington and the northern U.S. with dark red indicating a 70%+ probability of hotter than usual conditions. Texas and much of the southern states, on the other hand, may actually have to invest in a sweater or two.
Class Dismissed: Your Take-Home Message Is it the end of the world? Should you start looting your neighborhood grocery store and stocking up on bottled water and canned beans? No. Well, no to the first one: no harm ever came from having an extra can of baked beans, but you may want to prepare your home if you’re in an area that’s at risk of flood or drought. The question on the media’s lips is: is this particularly strong El Niño event proof of climate change and the severe weather we can come to expect from a globally warmer atmospheric environment?
Until we can say what causes the easterly trade winds to die down every two to seven years, we won’t be able to define the relationship between El Niño events and global warming. What is pretty evident – and has been talked about by climate scientists for years – is that a warmer atmosphere contains more moisture (due to greater evaporation) and more energy and is therefore more prone to the development of severe storms.
Your take-home message is this: The atmosphere is like the movie Cloud Atlas: It’s complicated and no matter how closely you study it, you still wonder what the f**k happened in the end. Just remember that the next time you hurl insults at the weatherman for getting the forecast wrong!
