Sadiq Khan’s green credentials may be critical in London mayoral election
Sat, 27 Apr 2024 04:00:24 GMT
As mayor aims to win third term, what has he achieved so far on air pollution, the climate crisis and nature?
When Sadiq Khan launched his campaign for a third term as Labour mayor of London, he put his green policies front and centre, highlighting his work on air pollution, the climate crisis and nature.
For seasoned Khan watchers, this came as little surprise. The mayor, who last year published a book called Breathe: Seven Ways to Win a Greener World, has been widely praised for his work tackling air pollution, as well as his efforts on nature restoration and getting London to net zero by 2030.
The introduction and expansion of the ultra-low emission zone, which excludes the most polluting vehicles from the capital and has contributed to roadside N02 emissions dropping by 50%.
The introduction of thousands of new electric buses and taxis, and the continued expansion of the cycle network and promotion of walking.
A rewilding programme that has reintroduced a range of species, including beavers, expanded green spaces, and included a mass tree-planting programme.

Ever wondered what you’d do if your musical hero got cancelled? This crushing scenario is brought to life in an impressive first novel by Nicolas Padamsee (one of the Observer’s best 2024 debut novelists). A nuanced and remarkably assured exploration of Britishness, toxic masculinity and the pernicious pull of the far right, England Is Mine charts a rapid descent into extremism fuelled by fandom and disillusionment.
David, one of two main characters, is a teenager of Iranian heritage living in east London. A social outcast who struggles with his image (bullies at sixth form call him “Makeup Boy”), he finds refuge in the music of Karl Williams, an outspoken solo artist who, during a show in Leeds, makes an Islamophobic comment about Muslim children being withdrawn from a local primary school because of LGBTQ teaching. “Could it be that maybe, maybe, Islam isn’t 100% compatible with western values?” he goads the crowd. “You tell me.” While initially reticent, David feels that the public backlash against Williams is excessive. This position becomes more entrenched after David is assaulted by two young Muslims – one of whom he knows from college – setting him on a dark path that spirals towards catastrophe.

Cruising is booming – 2023 ticket sales have surpassed historic levels and 2024 has seen the launch of the largest cruise ship ever built. But as cruise tourism's popularity has increased, so have the pollution problems it brings. To customers, it may not be evident that any problems exist, since some cruise line companies claim to be becoming more climate-friendly. But the truth can be quite different.

SEMrush and Ahrefs are among
the most popular tools in the SEO industry. Both companies have been in
business for years and have thousands of customers per month.
If you're a professional SEO or trying to do digital
marketing on your own, at some point you'll likely consider using a tool to
help with your efforts. Ahrefs and SEMrush are two names that will likely
appear on your shortlist.
In this guide, I'm going to help you learn more about these SEO tools and how to choose the one that's best for your purposes.
What is SEMrush?
SEMrush is a popular SEO tool with a wide range of
features—it's the leading competitor research service for online marketers.
SEMrush's SEO Keyword Magic tool offers over 20 billion Google-approved
keywords, which are constantly updated and it's the largest keyword database.
The program was developed in 2007 as SeoQuake is a
small Firefox extension
Features
Ahrefs is a leading SEO platform that offers a set of
tools to grow your search traffic, research your competitors, and monitor your
niche. The company was founded in 2010, and it has become a popular choice
among SEO tools. Ahrefs has a keyword index of over 10.3 billion keywords and
offers accurate and extensive backlink data updated every 15-30 minutes and it
is the world's most extensive backlink index database.
Features
Direct Comparisons: Ahrefs vs SEMrush
Now that you know a little more about each tool, let's
take a look at how they compare. I'll analyze each tool to see how they differ
in interfaces, keyword research resources, rank tracking, and competitor
analysis.
User Interface
Ahrefs and SEMrush both offer comprehensive information
and quick metrics regarding your website's SEO performance. However, Ahrefs
takes a bit more of a hands-on approach to getting your account fully set up,
whereas SEMrush's simpler dashboard can give you access to the data you need
quickly.
In this section, we provide a brief overview of the elements
found on each dashboard and highlight the ease with which you can complete
tasks.
AHREFS
The Ahrefs dashboard is less cluttered than that of
SEMrush, and its primary menu is at the very top of the page, with a search bar
designed only for entering URLs.
Additional features of the Ahrefs platform include:
SEMRUSH
When you log into the SEMrush Tool, you will find four
main modules. These include information about your domains, organic keyword
analysis, ad keyword, and site traffic.
You'll also find some other options like
Both Ahrefs and SEMrush have user-friendly dashboards,
but Ahrefs is less cluttered and easier to navigate. On the other hand, SEMrush
offers dozens of extra tools, including access to customer support resources.
When deciding on which dashboard to use, consider what
you value in the user interface, and test out both.
If you're looking to track your website's search engine
ranking, rank tracking features can help. You can also use them to monitor your
competitors.
Let's take a look at Ahrefs vs. SEMrush to see which
tool does a better job.
The Ahrefs Rank Tracker is simpler to use. Just type in
the domain name and keywords you want to analyze, and it spits out a report
showing you the search engine results page (SERP) ranking for each keyword you
enter.
Rank Tracker looks at the ranking performance of
keywords and compares them with the top rankings for those keywords. Ahrefs
also offers:
You'll see metrics that help you understand your
visibility, traffic, average position, and keyword difficulty.
It gives you an idea of whether a keyword would be
profitable to target or not.
SEMRush offers a tool called Position Tracking. This
tool is a project tool—you must set it up as a new project. Below are a few of
the most popular features of the SEMrush Position Tracking tool:
All subscribers are given regular data updates and
mobile search rankings upon subscribing
The platform provides opportunities to track several
SERP features, including Local tracking.
Intuitive reports allow you to track statistics for the
pages on your website, as well as the keywords used in those pages.
Identify pages that may be competing with each other
using the Cannibalization report.
Ahrefs is a more user-friendly option. It takes seconds
to enter a domain name and keywords. From there, you can quickly decide whether
to proceed with that keyword or figure out how to rank better for other
keywords.
SEMrush allows you to check your mobile rankings and
ranking updates daily, which is something Ahrefs does not offer. SEMrush also
offers social media rankings, a tool you won't find within the Ahrefs platform.
Both are good which one do you like let me know in the comment.
Keyword research is closely related to rank tracking,
but it's used for deciding which keywords you plan on using for future content
rather than those you use now.
When it comes to SEO, keyword research is the most
important thing to consider when comparing the two platforms.
The Ahrefs Keyword Explorer provides you with thousands
of keyword ideas and filters search results based on the chosen search engine.
Ahrefs supports several features, including:
SEMrush's Keyword Magic Tool has over 20 billion
keywords for Google. You can type in any keyword you want, and a list of
suggested keywords will appear.
The Keyword Magic Tool also lets you to:
Both of these tools offer keyword research features and
allow users to break down complicated tasks into something that can be
understood by beginners and advanced users alike.
If you're interested in keyword suggestions, SEMrush
appears to have more keyword suggestions than Ahrefs does. It also continues to
add new features, like the Keyword Gap tool and SERP Questions recommendations.
Both platforms offer competitor analysis tools,
eliminating the need to come up with keywords off the top of your head. Each
tool is useful for finding keywords that will be useful for your competition so
you know they will be valuable to you.
Ahrefs' domain comparison tool lets you compare up to five websites (your website and four competitors) side-by-side.it also shows you how your site is ranked against others with metrics such as backlinks, domain ratings, and more.
Use the Competing Domains section to see a list of your
most direct competitors, and explore how many keywords matches your competitors
have.
To find more information about your competitor, you can
look at the Site Explorer and Content Explorer tools and type in their URL
instead of yours.
SEMrush provides a variety of insights into your
competitors' marketing tactics. The platform enables you to research your
competitors effectively. It also offers several resources for competitor
analysis including:
Traffic Analytics helps you identify where your
audience comes from, how they engage with your site, what devices visitors use
to view your site, and how your audiences overlap with other websites.
SEMrush's Organic Research examines your website's
major competitors and shows their organic search rankings, keywords they are
ranking for, and even if they are ranking for any (SERP) features and more.
The Market Explorer search field allows you to type in
a domain and lists websites or articles similar to what you entered. Market
Explorer also allows users to perform in-depth data analytics on These
companies and markets.
SEMrush wins here because it has more tools dedicated to
competitor analysis than Ahrefs. However, Ahrefs offers a lot of functionality
in this area, too. It takes a combination of both tools to gain an advantage
over your competition.
When it comes to keyword data research, you will become
confused about which one to choose.
Consider choosing Ahrefs if you
Consider SEMrush if you:
Both tools are great. Choose the one which meets your
requirements and if you have any experience using either Ahrefs or SEMrush let
me know in the comment section which works well for you.

US secretary of state to discuss avoiding regional conflict amid fears about Israeli ground invasion of Rafah
The US secretary of state, Antony Blinken, will travel to Saudi Arabia to try to restart fraught ceasefire negotiations between Hamas and Israel and discuss efforts to prevent spiralling regional conflict, while other senior US officials claimed Israel was willing to listen to their fears about a ground invasion of Gaza’s southernmost city.
A delegation from Hamas, expected in Cairo in parallel to Blinken’s visit, said they would provide a response to an Israeli proposal focused on an initial hostage release.

‘We should really check that,’ I say to my wife about our son’s passport, which we’d suddenly remembered might be going out of date soon. With a sharp dart of sweating horror, I grab it from the drawer and discover it has indeed expired, just two days earlier – and we are due to fly to Dublin in six days. We decide our only option is to book ourselves on to a later ferry instead.
The problem with the ferry is it means six hours of driving through England and Wales. (And if you’re wondering whether our kids were sick during this trip, you’ll be delighted to know that our daughter vomited twice before we’d even reached the M25. Our son, perhaps affected by the miasma, or maybe sensing a deficit in attention, caught up and was himself sick three times, before his sister chimed in with one last spew 20 minutes before we reached the boat, to make it a creditable 3-3 draw.)

With stunning sunsets, one of the most beautiful beaches in the Mediterranean and must-see medieval cities, Croatia’s coast and islands are nothing short of spectacular
Once seen, never forgotten. Croatia’s fabulously beautiful coast and islands (1,246 to be precise) – with their rocky coves, iconic beaches, historic towns and gorgeous sunsets, all surrounded by some of the most breathtakingly blue waters imaginable – are places that stay in the mind, and they have a habit of luring you back.
Rovinj in Istria is one of the most instantly recognisable towns on the Croatian coast, its narrow streets and colourful facades climbing upwards to a soaring bell tower, modelled on that of St Mark’s Basilica in Venice. Travel north just a little and you’ll reach Poreč, home to Unesco-listed Byzantine mosaics to rival those in Ravenna or Istanbul – or south to Pula, with its magnificently preserved Roman amphitheatre. For a peaceful oasis set among some of the country’s finest vineyards, head just five miles inland from the sea walls of Novigrad to Brtonigla.

The small indulgence of chocolate is becoming a more costly one. Soaring prices for cocoa beans recently hit a record $12,000 a tonne: roughly four times last year’s price. Many think they will go higher. That means smaller or more expensive bars and reformulated recipes for many consumers, and may put out of business small specialist producers. Yet it is bringing little reward to struggling growers.
The immediate culprit is a bad harvest in west Africa – which produces 70% of the world’s beans – reflecting El Niño-linked weather patterns and disease. Major processing plants in Ghana and Ivory Coast, the main growers, have halted or reduced operations because they cannot afford the beans. But underlying the crisis are longer-term issues including the climate crisis and the inability of farmers to invest in production due to their low incomes. Big companies have long claimed that it simply wasn’t viable to pay more for beans. Now they are suddenly finding that they can, in fact, manage to do so when the market demands it. Cocoa amounts for only around a tenth of the costs of producing a bar.

Emily is a 24-year-old single female with anorexia nervosa and depression who was referred for an assessment due to restricting food intake, being underweight with some alcohol abuse. Emily had been living in a share house but has returned to living with her parents due to her worsening mental health.
Anorexia nervosa is a psychiatric disease in which patients restrict their food intake (by extreme diets, purging and excessive exercise). Patients become severely underweight and do not realise it and have a distorted perception of weight. But eating disorders are treatable and can lead to good outcomes.

I ask our waiter what it is. “Exactly what it sounds like,” Tom says, cheerily. “The staff food is so much better here than I’m used to. Usually, it’s chicken nuggets. Not here. Today it was a pea risotto. We’ve had leek and bacon pie, and a cottage pie. It’s great.” They just happen to make enough to sell a few portions to the punters, too, though today they’ve already run out. No worries. There are other things worth ordering.

From baroque music events to medieval architecture and delicious Adriatic cuisine, Croatia has something for everyone
Croatia’s fabulous mishmash of cultures – from ancient Greeks to Romans, Venetians, Austrians, Hungarians and Italians – has left a rich legacy all around the country. You’ll see it in the Venetian architecture of Rovinj, Korčula, Dubrovnik and Hvar, the Habsburg townhouses of Zagreb and Opatija, and the ancient Roman ruins of Istria and Dalmatia. You’ll taste it in the delicious cuisine where the Adriatic and central Europe meet and mingle.
You’ll hear it when top-flight performers bring their magic to the Dubrovnik Summer Festival, the Split Summer Festival and the baroque music festivals of Korčula and Varaždin. Sultry Dalmatian summer nights echo to the sound of polyphonic klapa singers whose a cappella music makes the skin tingle. The klapa festival in the beautiful Dalmatian coastal town of Omiš every July is one of the summer’s unmissable events.

Continue reading...Imagine a world in which you can do transactions and many other things without having to give your personal information. A world in which you don’t need to rely on banks or governments anymore. Sounds amazing, right? That’s exactly what blockchain technology allows us to do.
It’s like your computer’s hard drive. blockchain is a technology that lets you store data in digital blocks, which are connected together like links in a chain.
Blockchain technology was originally invented in 1991 by two mathematicians, Stuart Haber and W. Scot Stornetta. They first proposed the system to ensure that timestamps could not be tampered with.
A few years later, in 1998, software developer Nick Szabo proposed using a similar kind of technology to secure a digital payments system he called “Bit Gold.” However, this innovation was not adopted until Satoshi Nakamoto claimed to have invented the first Blockchain and Bitcoin.
A blockchain is a distributed database shared between the nodes of a computer network. It saves information in digital format. Many people first heard of blockchain technology when they started to look up information about bitcoin.
Blockchain is used in cryptocurrency systems to ensure secure, decentralized records of transactions.
Blockchain allowed people to guarantee the fidelity and security of a record of data without the need for a third party to ensure accuracy.
To understand how a blockchain works, Consider these basic steps:
Let’s get to know more about the blockchain.
Blockchain records digital information and distributes it across the network without changing it. The information is distributed among many users and stored in an immutable, permanent ledger that can't be changed or destroyed. That's why blockchain is also called "Distributed Ledger Technology" or DLT.
Here’s how it works:
And that’s the beauty of it! The process may seem complicated, but it’s done in minutes with modern technology. And because technology is advancing rapidly, I expect things to move even more quickly than ever.
Even though blockchain is integral to cryptocurrency, it has other applications. For example, blockchain can be used for storing reliable data about transactions. Many people confuse blockchain with cryptocurrencies like bitcoin and ethereum.
Blockchain already being adopted by some big-name companies, such as Walmart, AIG, Siemens, Pfizer, and Unilever. For example, IBM's Food Trust uses blockchain to track food's journey before reaching its final destination.
Although some of you may consider this practice excessive, food suppliers and manufacturers adhere to the policy of tracing their products because bacteria such as E. coli and Salmonella have been found in packaged foods. In addition, there have been isolated cases where dangerous allergens such as peanuts have accidentally been introduced into certain products.
Tracing and identifying the sources of an outbreak is a challenging task that can take months or years. Thanks to the Blockchain, however, companies now know exactly where their food has been—so they can trace its location and prevent future outbreaks.
Blockchain technology allows systems to react much faster in the event of a hazard. It also has many other uses in the modern world.
Blockchain technology is safe, even if it’s public. People can access the technology using an internet connection.
Have you ever been in a situation where you had all your data stored at one place and that one secure place got compromised? Wouldn't it be great if there was a way to prevent your data from leaking out even when the security of your storage systems is compromised?
Blockchain technology provides a way of avoiding this situation by using multiple computers at different locations to store information about transactions. If one computer experiences problems with a transaction, it will not affect the other nodes.
Instead, other nodes will use the correct information to cross-reference your incorrect node. This is called “Decentralization,” meaning all the information is stored in multiple places.
Blockchain guarantees your data's authenticity—not just its accuracy, but also its irreversibility. It can also be used to store data that are difficult to register, like legal contracts, state identifications, or a company's product inventory.
Blockchain has many advantages and disadvantages.
I’ll answer the most frequently asked questions about blockchain in this section.
Blockchain is not a cryptocurrency but a technology that makes cryptocurrencies possible. It's a digital ledger that records every transaction seamlessly.
Yes, blockchain can be theoretically hacked, but it is a complicated task to be achieved. A network of users constantly reviews it, which makes hacking the blockchain difficult.
Coinbase Global is currently the biggest blockchain company in the world. The company runs a commendable infrastructure, services, and technology for the digital currency economy.
Blockchain is a decentralized technology. It’s a chain of distributed ledgers connected with nodes. Each node can be any electronic device. Thus, one owns blockhain.
Bitcoin is a cryptocurrency, which is powered by Blockchain technology while Blockchain is a distributed ledger of cryptocurrency
Generally a database is a collection of data which can be stored and organized using a database management system. The people who have access to the database can view or edit the information stored there. The client-server network architecture is used to implement databases. whereas a blockchain is a growing list of records, called blocks, stored in a distributed system. Each block contains a cryptographic hash of the previous block, timestamp and transaction information. Modification of data is not allowed due to the design of the blockchain. The technology allows decentralized control and eliminates risks of data modification by other parties.
Blockchain has a wide spectrum of applications and, over the next 5-10 years, we will likely see it being integrated into all sorts of industries. From finance to healthcare, blockchain could revolutionize the way we store and share data. Although there is some hesitation to adopt blockchain systems right now, that won't be the case in 2022-2023 (and even less so in 2026). Once people become more comfortable with the technology and understand how it can work for them, owners, CEOs and entrepreneurs alike will be quick to leverage blockchain technology for their own gain.
