While we all see the same sky, we see it a bit differently depending on where we stand.

For those in the planet’s most extreme regions, the sun doesn’t follow the same pattern of seasons as it does in more temperate regions.

Today’s visualization comes from Sleepopolis and summarizes the top cities on each continent that receive the most and least annual sunshine hours.

Ranked: Cities with the Least and Most Sunshine Hours

While the graphic groups the top five cities from each continent, the tables below highlight the top 10 cities from around the world that boast the highest and lowest annual sunshine hours.

Top 10 Cities with the Most Annual Sunshine

Las VegasUnited StatesArid3,825.3
TucsonUnited StatesArid3,806.0
KhargaEgyptArid3,790.8
El PasoUnited StatesSemiarid3,762.5

The sunniest city on Earth is Yuma, Arizona in the U.S. As the driest city in the U.S., Yuma receives less than 200 millimeters (8 inches) of rainfall and endures roughly 100 days of 40°C (104°F) weather every year. Yuma lies between the Gila and Colorado rivers, in a lush region that produces almost 90% of leafy vegetables grown in the U.S.

Arizona boasts three of the top 10 sunniest cities in the world, including Phoenix in the fifth spot, which is the 5th most populous city in the U.S. and is known as “the Valley of the Sun”.

Perhaps unsurprisingly, Egypt also has three cities in the top 10 list, with Marsa Alam, Dakhla Oasis, and Kharga claiming the 2nd, 3rd, and 9th sunniest spots, respectively. Dakhla Oasis, or “inner oasis”, receives practically zero precipitation each year.

Although perceived as a sunny location, Colombia borders both the Caribbean Sea and the Pacific Ocean, exposing it to higher variety in weather patterns and precipitation. Colombia alone is home to three of the top 10 cities with the lowest hours of annual sunshine.

Ranking second-to-last in the number of sunshine hours, Torshavn lies between the Scottish coast and Iceland and receives roughly 37 days of sunshine every year; the average temperatures on this island barely reach above 5°C (41°F).

Our sun doesn’t shine at the same level of brightness all the time. NASA has observed that the sun goes through “solar cycles” that last roughly 11 years─brightening and dimming at relatively regular intervals and impacting how intensely we receive sunlight at any given time.

Sunshine Near the Poles

Humans typically need exposure to the sun to maintain healthy sleep habits, as our brain has been hardwired to follow natural waking and sleeping rhythms.

However, several cities experience no sun at all for several months at a time in what’s known as the “Polar Night”.

  • Tromsø, Norway: winter darkness is enjoyed rather than endured, as it can last for over a month
  • Svalbard, Norway: even indirect sunlight is absent, with no change in sunlight to help indicate a 24-hour day
  • Dikson, Russia: receives no sunlight whatsoever in December

Wherever you live, people have been watching and tracking the movements of the sun with rapt attention for millennia, even when we couldn’t see it.

10 Ways You Can Build Leadership Communities in a Hybrid World of Work

Feeling disconnected? This infographic teaches you how to build strong leadership communities in your organization in a hybrid working world.

Published

on

The world has never been more connected. Yet many of us feel more disconnected than ever before.

In particular, CEOs and managers can often feel isolated from their peers, and therefore crave a greater sense of community and belonging. This lack of social connection can have a detrimental impact on both them and their team—putting the future of their company at risk.

Leading in a Hybrid World of Work

This infographic from bestselling author Vince Molinaro dives into the ways you can build a strong community of leaders in your organization, enabling you to more successfully execute on strategy, drive growth, and deliver results.

The Critical Need for Leadership Communities

In today’s world, many leaders have been conditioned to work and lead in a way that is individualistic and hyper-competitive, which leads to problematic outcomes including:

  • Limiting innovative ideas
  • Causing overwhelm and stress
  • Limiting diversity and a sense of inclusion
  • Promoting a macho culture
  • Creating heroes and zeros in organizations

This outdated model breeds a weak leadership culture. Even though leadership expectations are higher than ever, very few companies boast a strong leadership culture. In fact, just 15% of companies have the culture they need to succeed.

What does a weak leadership look like?

Weak Leadership Cultures

When leaders demonstrate the following behaviors, organizations are at risk of developing a weak leadership culture:

  1. They lack clarity around strategic priorities.
  2. They fail to inspire the people they lead.
  3. They tolerate ineffective and mediocre leadership.
  4. They demonstrate animosity for the success of other leads, teams, and departments.
  5. They work at cross-purposes with each other.
  6. They prop themselves up while downplaying the contribution of others.
  7. They don’t engage stakeholders.
  8. They regularly badmouth others and throw colleagues under the bus.
  9. They withhold information as a way to retain power over their peers.
  10. They act as bystanders when colleagues need help.

When these negative dynamics become apparent, organizations pay a significant price. According to a report from Qualtrics, 40% of managers see a decline in their mental health, while another study shows that 66% of leaders have checked out entirely.

It is clear that building a strong community of leaders has become critical as the world continues to become even more complex and uncertain. Let’s dive into some of the ways you can build a greater sense of belonging in your organization today.

The Characteristics of Leadership Communities

Here are the 10 characteristics and behaviors that promote a strong community of leaders. Does this describe your organization’s leadership culture?

CharacteristicAligned Behavior
1. Have clarity on the strategic direction of the organizationBe determined to deliver on the most important strategic outcomes for the company
2. Create excitement about the futureSpread optimism about the company, even through adversity
3. Share a common aspiration to be great as leadersCommit to their roles as leaders and help other leaders thrive
4. Lead with a united front and a one-company mindsetLead in the best interest of the whole organization
5. Hold each other accountable by calling out unproductive leadership behaviorDemonstrate the courage to call out misaligned and unacceptable behaviors
6. Celebrate success and key milestonesIgnite passion by recognizing others and showing progress towards goals
7. Break down silos and collaborate effectivelyIdentify accountability gaps that weaken the leadership culture
8. Keep internal politics and personal agendas to a minimumBehave in a direct and transparent manner with peers
9. Demonstrate resilience and resolve in the face of adversityTurn to each other while navigating tough challenges
10. Support one another and have each other’s backsBuild high-trust relationships with one another

Most leaders want to be in an environment where there is real clarity, alignment, commitment, and mutual support—it just takes one accountable leader to make it happen.

The Benefits to Creating a Strong Community of Leaders

If done right, the effects of building a strong community of leaders can be extraordinary:

  • Promotes a stronger sense of belonging.
  • Allows for greater knowledge sharing.
  • Encourages higher levels of performance.
  • Creates a culture of accountability.
  • Improves employee engagement.

Moreover, research shows that employee engagement is directly linked to a company’s culture and value system. In fact, employee engagement levels can reach up to 72% when managers work well with each other.

With the working world transforming before our very eyes, it’s time to establish a new leadership contract so that CEOs and managers can lead their organizations successfully into the future.

Animated Map: Visualizing Earth’s Seasons

Why does Earth have seasons?

Many people think the seasons are dictated by Earth’s proximity to the Sun, but this isn’t the case. It’s the Earth’s tilt, not its closeness to the Sun, that influences our seasons.

This animated map by Eleanor Lutz visualizes Earth’s seasons, showing how the temperature changes impact ice levels in the Arctic as well as vegetation more broadly. It also highlights the cloud cover and sunlight each hemisphere receives throughout the year, with each frame in the animation representing a month of time.

Why is Earth Tilted?

Unlike some of the planets that sit completely upright and rotate perpendicularly, Earth rotates on a 23.5-degree axis.

But why? A commonly accepted theory among the scientific community is the giant impact hypothesis. According to this theory, a celestial object called Theia collided with Earth many years ago, when the planet was still forming. This collision not only knocked Earth into its tilted position—some believe that the dust and debris from this impact ended up forming our moon.

Ever since, our planet has been rotating with a slight tilt (which itself is not fixed, as it “wobbles” in cycles), giving us our varying seasons throughout the year.

How Earth’s Tilt Influences our Seasons

As our planet orbits the Sun, it’s always leaning in the same direction. Because of its tilt, the different hemispheres receive varying amounts of sunlight at different times of the year.

In December, Earth is technically closer to the Sun than it is in June or July. However, because the Northern Hemisphere is tilted away from the Sun during December, that part of the planet experiences winter during that time.

Earth's Seasonal Climates

The graphic above by the Smithsonian Science Education Center (SSEC) visualizes Earth’s orbit throughout the year, showing when each hemisphere receives the most direct sunlight (and thus, experiences summer).

The Climate Change Impact

While our seasons have always varied, it’s worth noting that climate change has impacted our seasons, and changed how much Arctic ice we lose each summer.

In the past, millions of miles of ice remained frozen throughout the summer months. In the 1980s, there were 3.8 million square miles of ice in July—that’s roughly the same size as Australia.

Over the years, Arctic ice cover has steadily declined. In July 2020, the ice cover was only 2.8 million square miles—a million less than the amount four decades ago.

Some scientists are predicting that we could lose our summer sea ice entirely by 2035, which would have a devastating impact on the Artic’s wildlife and the indigenous people who live there.
