Weather tracker: Nigeria hit by deadly flooding described as ‘worst in 60 years'

Significant flooding affected Nigeria last week, with more than 150 deaths reported so far. Heavy rain struck the north of the country on Wednesday night and continued into Thursday, leading to flooding along the Niger River, displacing thousands and destroying hundreds of homes. The district head said it was the region's worst flood in 60 years.
Heavy rain is not unusual at this time of year in Nigeria. The country has a tropical climate and is influenced by the west African monsoon, with the wet season running from April until October. This type of seasonality is linked to land-sea temperature differences, alongside the shifting intertropical convergence zone (ITCZ), a band of low pressure roughly around the equator that shifts north and south with the angle of the sun.
From March to September, the sun favours the northern hemisphere, meaning there is greater incoming solar radiation here during this time. As land heats up faster than water, this creates surface low pressure over west Africa as air ascends over the region, which then allows moister air to move in from the Atlantic to later fall out as rain.
Additionally, the ITCZ moves northwards during the northern hemisphere summer, meaning this region of low pressure is now situated over north Africa, allowing for more precipitation there. In contrast, during the northern hemisphere winter, the ITCZ shifts southwards, leading to drier conditions in west Africa under higher pressure.
This week, Niger and Nigeria will continue to experience rainfall but also below-average temperatures. These will fall about 10C below normal early this week, with daytime maximums in the mid to high 20s compared with a climate average of mid- to high 30s Celsius.
Northern Africa also had some extreme weather, with a severe summer storm hitting Alexandria in Egypt on Saturday. The city was battered by heavy rain, strong winds and hail, which flooded the streets and caused power outages.

The conditions were attributed to a cold front linked to an area of low pressure that moved into Egypt over the weekend. The cold front introduced moisture and forced the warm air to rise, which later condensed, forming storm clouds. Although storms are common there in the winter and spring, they occur less frequently closer to summer.

Top 10 health benefits of beetroot according to sabi pipo

Sabi pipo say one of di powers of beetroot na say e dey rich in nitrates. Wen we digest food or drink wey dey rich in nitrate, nitric oxide dey dey produced, wey dey known to cause di blood vessels to widen. Sabi pipo believe say dis fit lead to some health benefits. One study find say a daily dose of beetroot juice fit get a significant effect on blood pressure. Di study find say just a few weeks of eating some beets a day lead to a fall in average blood pressure of about 5 millimetres of mercury, if maintained, e dey enough to reduce di risk of stroke and heart attack by 10% . Studies don also find say beetroot fit get effect on blood pressure within a few hours of intake. Prof Andy Jones, Professor of Applied Physiology from di University of Exeter wey spend years investigating di effects of beetroot on sport performance explain how di nitrates inside beetroot improve dey improve di blood flow to our lungs and muscles, resulting in a faster delivery of oxygen. "Di potential dey for di muscle to dey receive more oxygen and to distribute dat oxygen within imsef more effectively because of di effects of nitric oxide", e tok. Not only dis, dem dey help you make more efficient use of oxygen during exercise, so you fit work harder, without feeling di strain. Wetin be beetroot? E belong to di same family as chard and spinach, pesin fit eat both di leaves and root of beetroot fit dey eaten – di leaves get bitter taste whereas di root dey sweet. Although dem dey available all year round, beets dey di sweetest and most tender during dia peak season, wey for kontri like UK na from June to October. While varieties like white and yellow beets dey make pretty dishes, only red beets get cancer-fighting compound betacyanin. How much I fit dey eat? Prof Jones bin advise say two-three medium beetroots, or one shot of beetroot juice, na all you need to see positive effects. Getting about 6 to 10 millimoles of nitrate a day na wetin dey important. E advise to dey keep steady intake of nitrates every day and every week for long term benefit. Researchers from Barts and The London School of Medicine and Dentistry say to drink one cup of beetroot juice fit lower blood pressure. "If you dey drink 250ml (8oz) e go cut high blood pressure readings by 10mm of mercury (mmHg)." One study of 15 patients, bring some into di normal range, di journal Hypertension, external bin report. Afta three to six hours, dem detect di effect one day later. But di researchers, from Barts and The London School of Medicine and Dentistry, wey study beetroot blood pressure lowering effects for years, also warn say more work still dey needed. And dem warn say to dey drink beetroot juice fit get one unexpected consequence - e fit turn your urine pink. Nitrate dey naturally inside soil, wia big vegetables dey take am in through roots to help dem grow. Researcher Dr Amrita Ahluwalia tok: "We dey surprised by how little nitrate dey needed to see dat kind large effect. "Our hope na say to increase one intake of vegetables wit high dietary nitrate content, like green leafy vegetables or beetroot, fit be lifestyle approach wey pesin fit easily employ to improve cardiovascular health." Prof Peter Weissberg, medical director for di British Heart Foundation, wey bin fund di research, tok say: "e dey support current advice say make we all dey eat plenty of green vegetables. "But we need larger studies in patients to determine if nitrate-rich vegetables dey effective to lower blood pressure over di long term." Also, di nitrates dey water-soluble though, so you need dey careful wen you dey boiling beets. To boil your beets go allow nitrates to come out into di cooking liquid, so you no go get as many benefits. Sabi pipo say if you really wan get di most out of dis vegetable e fit be best to buy am raw and bake am, or drink di juice! Top 10 health benefits of beetroot 1. E dey rich in protective antioxidants Red beetroots dey ranked as one of di 10 most potent antioxidant vegetables. Dis mean say dem dey help di body combat di damaging effects of di process weyndem call oxidation. Di plant compounds wey dey responsible for di root purple-crimson colour, anthocyanins, don show to get high anti-oxidant and anti-inflammatory capabilities. 2. E fit get anti-cancer properties. Betacyanin, di powerful plant pigment wey dey give beetroot im rich colour, also dey help suppress di development of some types of cancer, including bladder cancer. Beetroot contain oda potential cancer-fighting compounds including ferric acid, ruin and kaempferol. 3. E fit get anti-inflammatory properties. Some research suggests say betalains, di family of natural colour pigments wey betacyanin belong to, fit help reduce di symptoms and markers of inflammation. Dis include potentially relieving discomfort of inflamed joints, like knees. 4. E fit lower blood pressure Beetroot naturally dey rich in compounds wey dem dey call nitrates, and na dis make beetroot so heart-friendly. Dis na sake of say nitrates dey help to improve blood flow by relaxing di blood vessels, wey potentially dey lower blood pressure. Reduced blood. Studies suggest say nitrate-rich foods, like beetroot, fit also help in heart attack survival. 5. E fit improve exercise performance and support energy levels Studies suggest say wen athletes add beetroot juice to dia regime, e fit support exercise endurance and improve performance. No be all be dat: wen muscles dey resting state afta exercise, di nitrates in beetroot dey help bring more oxygen to di muscle cells wey dey promote efficient recovery. For di rest of us, to dey add beetroot in our diets fit be di energy boost wey we need. 6. E fit improve digestive health. Beetroots dey rich in fibre wey, as well as supporting bowel function, dey help promote healthy environment in di gut. Alongside di fibre, betawains dey help increase di production of short chain fatty acids by di beneficial bacteria wey dey live inside di gut. 7. E fit protect di gut. Beetroots na one of di richest vegetable sources of glutamine, one amino acid wey dey key to di maintenance of our gut lining. E also fit be say di glutamine fit play a role to protect di gut lining from injury and stress. 8. E fit support brain health and reaction time Further studies also suggest say higher nitrate intake appear to lead to significant improvement in motor functions, including reaction time. 9. E fit be useful addition to a post-menopause diet. Afta menopause, blood pressure and heart disease risk dey increase. Dietary changes like di inclusion of nitrate-rich vegetables show to be useful strategy to help keep arteries flexible and in turn manage blood pressure. To drink beetroot juice before exercise fit also help improve mobility and cardio-metabolic outcomes in dis age group. All of wey suggest say beetroot fit get useful inclusion as part of a balanced diet for post-menopausal women. Any improvement in blood flow go also benefit di brain. Studies suggest say to include beetroot in di diet, combined wit exercise, fit improve blood flow to di frontal lobe of di brain - one area wey involve for decision making and memory. 10. E fit relieve symptoms of Raynaud phenomenon. Raynaud phenomenon na one uncomfortable condition wia di blood to di fingers and feet no dey flow properly. Symptoms include pain, numbness and pins and needles. One initial study wey dey examine di effects of beetroot juice demonstrate improvements in blood flow to di thumb and forearm as well as reduction in blood pressure and inflammation. Caution Although dis findings look promising, sabi pipo say more trials dey needed to validate dem. Also, remember to consult sabi person and your doctor if you get any health issue and before you make any change to diet.

Sustainable Switch Climate Focus: Storms hit China and Mexico

June 20 - This is an excerpt of the Sustainable Switch Climate Focus newsletter, where we make sense of companies and governments grappling with climate change on Fridays. To receive the full newsletter in your inbox for free sign up here. Hello, This week's Climate Focus takes a look at the storms that have wreaked havoc across China and Mexico. Central and southern China were on high alert for more flash floods on Friday as the annual East Asia monsoon gathered pace and extreme rainfall threatened disruption in the world's second-largest economy. Extreme rainfall and severe flooding, which meteorologists link to climate change, increasingly pose major challenges for policymakers. They threaten to overwhelm ageing flood defences, displace millions and wreak havoc on China's $2.8 trillion agricultural sector. China's rainy season, which arrived earlier than usual this year in early June, is usually followed by intense heat that scorches any crops that survive waterlogged soil, depletes reservoirs and warps roads and other infrastructure. Economic losses from natural disasters exceeded $10 billion last July, when the rainfall typically peaks. Over in Mexico, Hurricane Erick weakened to a tropical storm after making landfall on the southern Pacific coast on Thursday, leaving flooded streets and damaged boats and buildings in Oaxaca as authorities warned of dangerous rains. In coastal towns, residents began clearing debris. "There are many boats sunk here," fisherman Eduardo Gonzalez said in Puerto Escondido. "We're here to help our colleagues." "Life-threatening flooding and mudslides are expected, especially in areas of steep terrain," the U.S. National Hurricane Center said, forecasting up to 8 inches (20 cm) of rain for Guerrero state with up to 4 inches for its neighboring Oaxaca and Michoacan states. Mexico's environment ministry also had warned of waves of up to 10 meters (33 feet). WHAT TO WATCH - Saving the seas:Click here for a video on marine scientists working to restore underwater forests in Greece's northern Cyclades and click here for a Reuters story on scientists demanding action to protect environmentally important meadows of seagrass at Croatia's Dugi Otok island in the Adriatic Sea. Do check out this Reuters story on the vital underwater forest in the cold seas off Chile's arid northern coast that scientists say are threatened by warming oceans and human pollution. CLIMATE LENS Water watch: Since 2014, India has lost 60.33 billion units of coal-power generation across the country - equivalent to 19 days of coal-power supply at June 2025 levels - because water shortages force plants to suspend generation, according to federal data. Click here for a Reuters analysis on India's coal power boom facing challenges with water supplies. NUMBER OF THE WEEK $10 billion That's the amount raised in deals at a United Nations conference to protect the world's oceans – way below the estimated annual need – as investors seek clearer regulation on ocean management before committing funds. Between 2015 and 2019, only $10 billion was invested against the U.N. estimate of $175 billion in required annual funding. Think your friend or colleague should know about us?

African gay men blame President Trump for their recent HIV diagnoses after he cut prevention funding

Gay men in Africa are blaming President Trump's decision to cut funding for HIV /AIDS prevention for their diagnoses of the virus. The administration's sweeping cuts to foreign aid have reduced access to medications like Pre-Exposure Prophylaxis, or PrEP, which decreases the risk of contracting HIV by 99 percent. Emmanuel Cherem, 25, a gay men in Nigeria, told Reuters that he tested positive for HIV two months after losing access to the US-supplied drug. 'I blame myself... Taking care of myself is my first duty as a person,' he said. 'I equally blame the Trump administration because, you know, these things were available, and then, without prior notice, these things were cut off.' Echezona, 30, another gay man from Nigeria, told Reuters that he took PrEP pills daily for three years until he was told by a clinic worker that the drug was now only available to pregnant and lactating women. 'I just pray and wish that Trump actually changes his policy and everything comes back to normal so that the spread and transmission of the virus would be reduced,' he said. Trump issued an executive order on his first day in office that paused foreign development assistance for 90 days, while Secretary of State Marco Rubio signed a 'stop work order' to employees of the State Department's Office of Foreign Assistance. The department oversees the US Agency for International Development (USAID) and the President's Emergency Plan for AIDS Relief (PEPFAR), which have seen drastic cuts since Trump took office. The administration has defended its position, arguing that other countries need to shoulder the burden of providing aid. During South African President Cyril Ramaphosa's White House visit, Trump acknowledged that the foreign aid cuts have been 'devastating.' 'Hopefully a lot of people are going to start spending a lot of money,' Trump added. 'I've talked to other nations. We want them to chip in and spend money too, and we've spent a lot,' he continued. 'And it's a big - it's a tremendous problem going on in many countries. A lot of problems going on. The United States always gets the request for money. Nobody else helps.' Russell Vought, the director of the US Office of Management and Budget, echoed Trump's stance during a Congressional committee meeting in early June. He argued that African countries should take on the responsibility of fighting HIV/AIDS, alleviating the financial burden on the US. Vought added that some of the nonprofits facilitating HIV prevention programs 'are not geared toward the viewpoints of the administration.' The director's comments are in line with a waiver issued to PEPFAR programs on February 1 allowing prevention programs to restart only for pregnant mothers. Vulnerable populations, like members of the LGBTQIA+ community, sex workers, or injecting drug users, weren't included in the prevention measures. PEPFAR grants often covered the cost of clinics supplying PrEP at public health centers for these populations, which have suffered closures due to decreased funding. A spokesperson for the State Department told Reuters that PEPFAR-funded programs would continue to be reviewed for 'assessment of programmatic efficiencies and consistency with United States foreign policy.' Public health officials and activists fear that if Trump's hardline policy toward foreign aid stays consistent, HIV infections will continue in the region. Linda-Gail Bekker, an HIV expert at the University of Cape Town, said that African countries may not cover the expense of supplying the drug, leaving a gap for more diagnoses. 'It's as predictable as if you take your eye off a smoldering bushfire and the wind is blowing: a bushfire will come back,' she told Reuters. Countries like Malawi, Zimbabwe, and Mozambique were almost entirely dependent on US funding for HIV prevention measures, according to UNAIDS. Other countries, like Ethiopia, responded to the USAID funding cuts by introducing a new payroll tax to pay for HIV medication previously provided by US funding. Medical advancements for HIV prevention and treatment have progressed significantly in recent years. However, UNAIDS projects that gaps created by a lack of funding could see steps backward.
