🔆UN talks on drought deal in Saudi
✅The UN-hosted COP16 talks in Saudi Arabia failed to produce a binding protocol on drought response.
✅While no binding deal was reached, significant progress was made toward a future global drought regime, with plans to finalise it at COP17 in 2026 in Mongolia.
✅Droughts, exacerbated by environmental destruction, cost over $300 billion annually.
By 2050, 75% of the global population is expected to be affected by drought.
✅The UNCCD emphasised the need to restore 1.5 billion hectares of land by the decade’s end, requiring $2.6 trillion in global investments.

🔆Manganese:
✅Manganese is the fifth-most abundant metal on earth that exists in the form of oxides, carbonates and silicates.
✅It is present in water, soil and rock as a naturally occurring component.
Properties
✅It is too brittle to be of much use as a pure metal. It is mainly used in alloys, such as steel.
✅Its minerals are widely distributed, with pyrolusite (manganese dioxide) and rhodochrosite (manganese carbonate) being the most common.
✅It somewhat resembles iron in general chemical activity.
✅It oxidizes superficially in air and rusts in moist air.
✅It is obtained by reducing the oxide with sodium, magnesium or aluminium, or by the electrolysis of manganese sulfate.
✅Its ores are primarily found in Australia, South Africa, China, Gabon and Brazil.
✅It is essential for the growth of plants and is also involved in the assimilation of nitrates in plants and algae.

🔆GPS Spoofing:
✅GPS spoofing, also known as GPS simulation, refers to the practice of manipulating or tricking a GPS receiver by broadcasting false GPS signals.
✅Essentially, it misleads the GPS receiver into believing it is located somewhere it is not, resulting in the device providing inaccurate location data.
✅This form of cyberattack undermines the reliability of GPS data, which is vital for a variety of applications, from navigation to time synchronization and more.
📍How Does GPS Spoofing Work?
✅It exploits the inherent vulnerabilities in the GPS infrastructure – the weak signal strength of GPS satellites.
✅The Global Positioning System (GPS) functions by sending signals from satellites to GPS receivers on Earth.
✅These receivers then calculate their position based on the time it takes for these signals to arrive.
✅However, due to the weak signal strength of the GPS satellites, these signals can be easily overwhelmed by fake signals, resulting in inaccurate location data on the receiving device.
✅Typically, a GPS spoofer begins by acquiring a basic understanding of the victim’s GPS setup, including the types of signals it uses and how they are processed.
✅With that information, the attacker then sends counterfeit GPS signals that mimic the real ones.
✅These fake signals are stronger, causing the receiver to recognize them as authentic signals.
✅As a result, the victim’s GPS receiver ends up processing these counterfeit signals, leading to erroneous location information.
