The sun’s activity, which has knock-on effects on Earth, is increasing in volatility as scientists calculate it is peaking sooner than expected.
Expectations for peak solar activity – the solar maximum – have been brought forward to mid to late 2024 from previous forecasts of July 2025.
The solar maximum is part of the sun’s 11-year cycle, in which its north and south poles flip. With it comes increased solar activity that throws flares across space.
The effects on Earth are minimal but there can be some risks to communication, power supplies and satellites.
Solar maximum is the period of greatest solar activity in the 11-year solar cycle during which large numbers of sunspots appear and the solar output grows. Large solar storms often begin during the solar maximum.
The solar maximum is about halfway through the 11-year cycle. The solar minimum is usually when one cycle ends and the next starts.
Sunspots – areas of particularly strong magnetic forces that appear darker than their surroundings – thrown out during the solar maximum can be bigger than Earth.
Solar flares also release enormous amounts of radiation during the maximum
The current cycle, Solar Cycle 25, has been more active than expected, scientists at the US Space Weather Prediction Centre said.
The Sun is the Earth’s closest star. The increased solar activity sends charged particles into space.
When they reach the Earth’s magnetic field, they produce incredible polar light shows, known as the Aurora Borealis, or Northern Lights, and the Aurora Australis, or Southern Lights.
Solar flares can disrupt satellite operations and interfere with radio communications. Planes flying near the poles may also experience communication problems.
Power grids can be damaged by geomagnetic storms started by solar activity.
Flares send harmful radiation that can be dangerous to both astronauts and a spacecraft's electronics.
How green is the expo nursery?
Some 400,000 shrubs and 13,000 trees in the on-site nursery
An additional 450,000 shrubs and 4,000 trees to be delivered in the months leading up to the expo
Ghaf, date palm, acacia arabica, acacia tortilis, vitex or sage, techoma and the salvadora are just some heat tolerant native plants in the nursery
Approximately 340 species of shrubs and trees selected for diverse landscape
The nursery team works exclusively with organic fertilisers and pesticides
All shrubs and trees supplied by Dubai Municipality
Most sourced from farms, nurseries across the country
Plants and trees are re-potted when they arrive at nursery to give them room to grow
Some mature trees are in open areas or planted within the expo site
Green waste is recycled as compost
Treated sewage effluent supplied by Dubai Municipality is used to meet the majority of the nursery’s irrigation needs
Construction workforce peaked at 40,000 workers
About 65,000 people have signed up to volunteer
Main themes of expo is ‘Connecting Minds, Creating the Future’ and three subthemes of opportunity, mobility and sustainability.
Expo 2020 Dubai to open in October 2020 and run for six months
Managing the separation process
- Choose your nursery carefully in the first place
- Relax – and hopefully your child will follow suit
- Inform the staff in advance of your child’s likes and dislikes.
- If you need some extra time to talk to the teachers, make an appointment a few days in advance, rather than attempting to chat on your child’s first day
- The longer you stay, the more upset your child will become. As difficult as it is, walk away. Say a proper goodbye and reassure your child that you will be back
- Be patient. Your child might love it one day and hate it the next
- Stick at it. Don’t give up after the first day or week. It takes time for children to settle into a new routine.And, finally, don’t feel guilty.

How the bonus system works
The two riders are among several riders in the UAE to receive the top payment of £10,000 under the Thank You Fund of £16 million (Dh80m), which was announced in conjunction with Deliveroo's £8 billion (Dh40bn) stock market listing earlier this year.
The £10,000 (Dh50,000) payment is made to those riders who have completed the highest number of orders in each market.
There are also riders who will receive payments of £1,000 (Dh5,000) and £500 (Dh2,500).
All riders who have worked with Deliveroo for at least one year and completed 2,000 orders will receive £200 (Dh1,000), the company said when it announced the scheme.

The Melbourne Mercer Global Pension Index
The Melbourne Mercer Global Pension Index
Mazen Abukhater, principal and actuary at global consultancy Mercer, Middle East, says the company’s Melbourne Mercer Global Pension Index - which benchmarks 34 pension schemes across the globe to assess their adequacy, sustainability and integrity - included Saudi Arabia for the first time this year to offer a glimpse into the region.
The index highlighted fundamental issues for all 34 countries, such as a rapid ageing population and a low growth / low interest environment putting pressure on expected returns. It also highlighted the increasing popularity around the world of defined contribution schemes.
“Average life expectancy has been increasing by about three years every 10 years. Someone born in 1947 is expected to live until 85 whereas someone born in 2007 is expected to live to 103,” Mr Abukhater told the Mena Pensions Conference.
“Are our systems equipped to handle these kind of life expectancies in the future? If so many people retire at 60, they are going to be in retirement for 43 years – so we need to adapt our retirement age to our changing life expectancy.”
Saudi Arabia came in the middle of Mercer’s ranking with a score of 58.9. The report said the country's index could be raised by improving the minimum level of support for the poorest aged individuals and increasing the labour force participation rate at older ages as life expectancies rise.
Mr Abukhater said the challenges of an ageing population, increased life expectancy and some individuals relying solely on their government for financial support in their retirement years will put the system under strain.
“To relieve that pressure, governments need to consider whether it is time to switch to a defined contribution scheme so that individuals can supplement their own future with the help of government support,” he said.
