At Least 1 Million Bees Found Dead in Cape Town
Beekeepers in and around Cape Town, South Africa are facing significant losses of their pollinators in recent weeks.
The mass deaths have been linked to an insecticide called fipronil that was likely incorrectly used by the area's wine farmers, according to media reports.
Brendan Ashley-Cooper, the vice-chairperson of Western Cape Bee Industry Association, told the BBC about 100 of his hives were affected and between 1 million and 1.5 million bees died.
"A week ago we started getting calls that beekeepers were finding dead bees in front of their hives. I came to inspect my bee site and found similar results and found thousands upon thousands of dead bees in front of a lot of my bee hives," the commercial farmer told South African broadcaster eNCA.

The beekeepers suspected that the area's wine farmers were spraying their vineyards with a mix of ant poison and molasses, the Weekend Argus reported last week.
Ashley-Cooper sent a sample of the mixture to a laboratory in Cape Town, which determined that fipronil was the main ingredient in the sample, the West Argus reported over the weekend. The wine farmers have since stopped using the pesticide.
Other area beekeepers lost hives, including Lawrence Woollam, who told the West Argus his business will be severely impacted after losing between 90 percent and 100 percent of his bees.
Fipronil is a broad-spectrum insecticide used to control ants, beetles, cockroaches, fleas, ticks, termites and other insects. It works by disrupting the central nervous system of invertebrates.
As the South African explained, the bees were likely attracted to the sweetness of the molasses. After ingesting the potent mixture, they brought it back to their hives and infected the rest of their colony.
Both wild and managed bee hives in Cape Town's southern areas were affected, Ashley-Cooper told the BBC.
Honey bees and wild bees are vital for crop pollination and are a critical part of our food system. One out of every three bites of food we eat is dependent on bees for pollination, according to the Natural Resources Defense Council. However, bee populations are crashing around the world due to factors such as neonicotinoids, habitat loss and disease.
The Cape Town beekeepers, wine farmers and the government are now working together to find a solution to the problem. Further tests will be conducted to confirm whether the pesticide is to blame.
"The farmers have been very concerned about the bee die-off. We're having meetings with the farmers in the next couple of days to have a look if they have caused this problem and to see if we can find solutions," Ashley-Cooper told eNCA.

The speed and scale of the response to COVID-19 by governments, businesses and individuals seems to provide hope that we can react to the climate change crisis in a similarly decisive manner - but history tells us that humans do not react to slow-moving and distant threats.
A Game of Jenga<p>Think of it as a game of Jenga and the planet's climate system as the tower. For generations, we have been slowly removing blocks. But at some point, we will remove a pivotal block, such as the collapse of one of the major global ocean circulation systems, for example the Atlantic Meridional Overturning Circulation (AMOC), that will cause all or part of the global climate system to fall into a planetary emergency.</p><p>But worse still, it could cause runaway damage: Where the tipping points form a domino-like cascade, where breaching one triggers breaches of others, creating an unstoppable shift to a radically and swiftly changing climate.</p><p>One of the most concerning tipping points is mass methane release. Methane can be found in deep freeze storage within permafrost and at the bottom of the deepest oceans in the form of methane hydrates. But rising sea and air temperatures are beginning to thaw these stores of methane.</p><p>This would release a powerful greenhouse gas into the atmosphere, 30-times more potent than carbon dioxide as a global warming agent. This would drastically increase temperatures and rush us towards the breach of other tipping points.</p><p>This could include the acceleration of ice thaw on all three of the globe's large, land-based ice sheets – Greenland, West Antarctica and the Wilkes Basin in East Antarctica. The potential collapse of the West Antarctic ice sheet is seen as a key tipping point, as its loss could eventually <a href="https://science.sciencemag.org/content/324/5929/901" target="_blank">raise global sea levels by 3.3 meters</a> with important regional variations.</p><p>More than that, we would be on the irreversible path to full land-ice melt, causing sea levels to rise by up to 30 meters, roughly at the rate of two meters per century, or maybe faster. Just look at the raised beaches around the world, at the last high stand of global sea level, at the end of the Pleistocene period around 120,0000 years ago, to see the evidence of such a warm world, which was just 2°C warmer than the present day.</p>
Cutting Off Circulation<p>As well as devastating low-lying and coastal areas around the world, melting polar ice could set off another tipping point: a disablement to the AMOC.</p><p>This circulation system drives a northward flow of warm, salty water on the upper layers of the ocean from the tropics to the northeast Atlantic region, and a southward flow of cold water deep in the ocean.</p><p>The ocean conveyor belt has a major effect on the climate, seasonal cycles and temperature in western and northern Europe. It means the region is warmer than other areas of similar latitude.</p><p>But melting ice from the Greenland ice sheet could threaten the AMOC system. It would dilute the salty sea water in the north Atlantic, making the water lighter and less able or unable to sink. This would slow the engine that drives this ocean circulation.</p><p><a href="https://www.carbonbrief.org/atlantic-conveyor-belt-has-slowed-15-per-cent-since-mid-twentieth-century" target="_blank">Recent research</a> suggests the AMOC has already weakened by around 15% since the middle of the 20th century. If this continues, it could have a major impact on the climate of the northern hemisphere, but particularly Europe. It may even lead to the <a href="https://ore.exeter.ac.uk/repository/handle/10871/39731?show=full" target="_blank" rel="noopener noreferrer">cessation of arable farming</a> in the UK, for instance.</p><p>It may also reduce rainfall over the Amazon basin, impact the monsoon systems in Asia and, by bringing warm waters into the Southern Ocean, further destabilize ice in Antarctica and accelerate global sea level rise.</p>

Is it Time to Declare a Climate Emergency?<p>At what stage, and at what rise in global temperatures, will these tipping points be reached? No one is entirely sure. It may take centuries, millennia or it could be imminent.</p><p>But as COVID-19 taught us, we need to prepare for the expected. We were aware of the risk of a pandemic. We also knew that we were not sufficiently prepared. But we didn't act in a meaningful manner. Thankfully, we have been able to fast-track the production of vaccines to combat COVID-19. But there is no vaccine for climate change once we have passed these tipping points.</p><p><a href="https://www.weforum.org/reports/the-global-risks-report-2021" target="_blank">We need to act now on our climate</a>. Act like these tipping points are imminent. And stop thinking of climate change as a slow-moving, long-term threat that enables us to kick the problem down the road and let future generations deal with it. We must take immediate action to reduce global warming and fulfill our commitments to the <a href="https://www.ipcc.ch/sr15/" target="_blank" rel="noopener noreferrer">Paris Agreement</a>, and build resilience with these tipping points in mind.</p><p>We need to plan now to mitigate greenhouse gas emissions, but we also need to plan for the impacts, such as the ability to feed everyone on the planet, develop plans to manage flood risk, as well as manage the social and geopolitical impacts of human migrations that will be a consequence of fight or flight decisions.</p><p>Breaching these tipping points would be cataclysmic and potentially far more devastating than COVID-19. Some may not enjoy hearing these messages, or consider them to be in the realm of science fiction. But if it injects a sense of urgency to make us respond to climate change like we have done to the pandemic, then we must talk more about what has happened before and will happen again.</p><p>Otherwise we will continue playing Jenga with our planet. And ultimately, there will only be one loser – us.</p>
