The Carbon Budget

There’s a limited amount of carbon we can put in the atmosphere before reaching the 1.5°C above pre-industrial levels, the threshold before human emissions significantly influence global temperatures. This is called, the carbon budget. At the current rate of emissions, the Global Carbon Budget team estimates a 50% chance global warming will exceed 1.5°C consistently in about six years.

Reflection

Even in the best case scenario (#1), extreme weather is more common, there will still be risks to health, 70 to 90% of the coral reef will be lost and there will likely be 69 million people at risk by sea level rise.

Sadly, we don’t seem to be on track to achieve scenario #1. Here’s a visual report from GlobalCarbonBudget.org, lead by University of Exeter with the support of more than 100 people from 70 organisations in 18 countries:

First of all, there’s something we need to learn from climate change deniers.

Climate deniers are congruent, they don’t believe in Climate Change and they act accordingly. But I know a lot of people who do believe in Climate Change and mostly act as if nothing’s going to happen (me included). See David Finnigan unpacking this contradiction at the TED stage. In a nutshell, climate change believers go about our lives doing very small things that ease our minds but don’t really make a big impact.

Pew Research Center reports about the Knowledge-Action Gap showing that 64% of people support the idea of sustainable behavior, yet only 26% of them actually engage in sustainable action. Furthermore, as read in The Carbon Almanac: “People tend to underestimate the most impactful climate actions, like voting for leaders who are prepared to fight the climate problem, while overestimating less impactful ones like recycling and replacing lightbulbs.”

Act as if you truly believe it

If you really want to live like you believe in Climate Change, I encourage you (and myself!) to do things that really matter. Here’s my recommended ranking of action:

1. Enormous impact
   • Join the ranks of people working on Sustainability full time. Invest your full time and energy, we need it now!
2. Large impact
   • Civic and social action. If you’re not ready to change your full time job, actively join a climate cause and invest a share of your time, energy and network connections. For example, join climate initiatives aimed at families, get ten friends to support a climate cause with you, or campaign for political candidates who support climate change initiatives.
3. Medium impact, but still super important!
   • Vote with your wallet every day, in every decision you make. Here are the most impactful things you can do:
   • Make the switch to an electric vehicle today!
   • Stop eating beef now!
   • Refrain from using any kind of single-use plastic, now!
   • Buy used/refurbished stuff whenever possible, and really push yourself here!
   • Stop buying new technology just because there’s a new version available. Fight planned obsolescence!
   • Stop going on vacations to places you need to fly to.
   • Make a conscious decision on which bank you choose to put your money in.
4. Small impact, but by all means, keep it up:
   • Save paper, recycle, install LED bulbs replacing incandescent ones, shop with reusable bags, etc.

See Ayana Elizabeth Johnson going into more details on the TED stage:

As reported by Columbia University Climate School, the favored refrain of climate deniers and those who oppose climate policies is that “the science is not settled.” To some degree, this is true. Climate scientists are still uncertain about a number of phenomena. But it is the nature of science to never be settled — science is always a work in progress, constantly refining its ideas as new information arrives.

Certain evidence, however, is clear: global temperatures are rising, and humans are playing a role in it. And just because scientists are uncertain about some other areas, does not negate what they are sure about.

An established fact

The Intergovernmental Panel on Climate Change (IPCC), is the United Nations body for assessing the science related to climate change. The IPCC is an organization of governments that are members of the United Nations or the World Meteorological Organization, it currently has 195 members. Thousands of people from all over the world contribute to the work of the IPCC.

The rate of change since the mid-20th century is unprecedented over millennia.

According to NASA, the current warming trend is different because it is clearly the result of human activities since the mid-1800s, and is proceeding at a rate not seen over many recent millennia. While Earth’s climate has changed throughout its history, the current warming is happening at a rate not seen in the past 10,000 years.

It is undeniable that human activities have produced the atmospheric gases that have trapped more of the Sun’s energy in the Earth system.

Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years. The level of CO₂ is now higher than at any time in the past 800,000 years.

The 10 most recent years are the warmest years on record.

NASA’s analysis generally matches independent analyses prepared by the​ National Oceanic and Atmospheric Administration (NOAA) and other research groups. Overall, Earth was about 1.36 degrees Celsius warmer in 2023 than in the late 19th-century (1850-1900) preindustrial average.

In the face of uncertainty

The report from Columbia University Climate School also concludes: The uncertainties in climate science that remain are not a justification for not acting to slow climate change, because uncertainty can work both ways: Climate change could prove to be less severe than current projections, but it could also be much worse.

Lastly, here are a couple of great resources to keep track of progress, or lack thereof.

• The Global Carbon Atlas: Explore and visualize the most up-to-date data on carbon fluxes resulting from human activities and natural processes. With fossil fuel emissions by country and city, land usage change, budgets, carbon monitor and much more!
• Climate Action Tracker: Tracks government climate action and measures it against the globally agreed Paris Agreement aim of “holding warming well below 2°C, and pursuing efforts to limit warming to 1.5°C.”

• More than 20% of the global greenhouse gases emissions (13.6 gigatons per year) are a direct result of food production, 61% of that can be traced to three main factors related to meat production:
  • Destruction of carbon-reducing forests and habitats to make way for pasture land
  • Pasture grown with carbon-producing fertilizers
  • Cattle and sheep producing large amounts of methane as a byproduct of the digestive process
• Methane is one of the most potent greenhouse gases (80 times stronger than CO₂)
• Beef production generates 30 pounds of CO₂ for every pound of meat

From my own experience leading the OKR process for large teams within Google for several years, I’ve seen firsthand how this deceptively simple framework can be challenging to implement effectively. Crafting well-formed Objectives and Key Results is hard—it requires time, many iterations, and a lot of learning along the way. Even in a company like Google, it’s surprising how few teams truly master OKR execution. Keeping them alive and relevant demands constant effort and attention, but when done right, OKRs provide incredible clarity and focus that drive strategic execution.

A Brief History of OKRs

The OKR journey began in the early 1970s at Intel, where Andy Grove, one of the company’s founders, developed the concept. Grove emphasized the importance of setting clear, measurable goals that aligned teams and individuals with the company’s mission.

John Doerr, who worked closely with Grove at Intel, played a crucial role in popularizing OKRs. He introduced the framework to companies like Google, helping them scale operations while maintaining a sharp focus on results. Doerr’s book, “Measure What Matters,” further articulates the effectiveness of OKRs in driving accountability and organizational alignment.

The OKR Framework Explained

At its core, the OKR framework is designed to foster clarity, focus, and alignment across an organization. It consists of two primary components:

• Objectives: These are the high-level goals you want to achieve. Objectives should be ambitious, inspirational, and qualitative, providing a clear direction for your team. They should be well connected with higher lever strategic goals.
• Key Results: These are the measurable outcomes that indicate progress toward achieving the objective. Key Results should be quantitative and time-bound, allowing teams to assess their performance effectively.

Best Practices for Creating Objectives

1. Be Specific and Inspirational: Your objectives should be clear and motivating. Aim for language that excites and challenges your team.
2. Limit the Number: Focus on a handful of objectives—three to five is ideal. This concentration helps teams prioritize and maintain focus.
3. Align with Company Goals: Ensure your objectives align with broader organizational goals. This alignment promotes cohesion and collective effort toward shared outcomes.

Best Practices for Creating Key Results

1. Be Measurable: Your Key Results should be quantifiable. Use numbers and metrics to define success clearly, making it easy to track progress. Think SMART!
2. Set Challenging but Achievable Targets: Strive for ambitious Key Results that push your team but remain attainable. This balance fosters motivation and commitment. Be careful, targets that are too challenging might demotivate the team, whereas targets that are too easy to achieve won’t enable you to challenge the status quo or get full productivity from the team.
3. Time-Bound: Each Key Result should have a specific deadline. This sense of urgency helps maintain momentum and accountability.

Here’s an example of a well-structured set of OKRs for a fictional tech company aiming to improve its product offering:

• Objective: Create a world-class mobile experience that delights users.
  • Key Result 1: Increase user satisfaction score from 75% to 90% by Q4.
  • Key Result 2: Reduce average app load time from 4 seconds to 2 seconds by the end of Q3.
  • Key Result 3: Achieve a 20% increase in daily active users by the end of Q4.

Important reminder: Don’t let the simplicity of this example deceive you. Achieving this level of clarity can take you months if not quarters when applying OKRs to your line of business. Keep trying and iterating, practice makes perfect!

Bringing OKRs to Life

Setting Objectives and Key Results (OKRs) is just the beginning of a journey towards achieving meaningful outcomes. To truly harness the power of OKRs, organizations must ensure they are not just a one-time exercise but an ongoing, dynamic process. This requires establishing regular check-ins, evaluating progress, and adapting to the ever-changing business landscape. Here’s how to bring OKRs to life within your teams and organization.

Regular Check-Ins: The Heartbeat of OKRs

To keep OKRs alive, organizations should set up a rhythm for regular check-ins—typically on a monthly or quarterly basis. These meetings provide opportunities to:

• Review Progress: Assess how teams are tracking against their Key Results. Are they on target, ahead, or behind schedule? Use a simple grading system (e.g., Red, Yellow, Green) to indicate progress.
• Facilitate Open Discussions: Create space for team members to discuss any obstacles they face and the lessons learned along the way. Share challenges, successes and insights regarding their progress and celebrate achievements.
• Adjust as Needed: Discuss whether the current Key Results still align with the organization’s strategic objectives and whether any adjustments are necessary. Outline specific actions that will be taken in the upcoming period, ensuring clarity on responsibilities and timelines.

A Yearly Process: Reflecting and Resetting

At the end of each year, it’s essential to conduct a comprehensive review of the OKR process:

• Reflect on Learnings: Analyze what worked well and what didn’t. Gather feedback from teams about their experiences with the OKR framework.
• Reset Objectives: Based on the insights gained, set new objectives for the upcoming year that align with the organization’s evolving vision and strategy.
• Revise Processes: Evaluate the effectiveness of the check-in processes and make adjustments as necessary to improve efficiency and engagement.

Conclusion

OKRs are more than just a goal-setting framework; they are a vital tool for translating vision into actionable strategy. By aligning daily operations with a compelling vision and a strategic plan, organizations can foster a culture of focus, accountability, and continuous improvement.

Implementing OKRs is a continuous, iterative process that goes beyond simple goal-setting. It creates a dynamic environment that promotes growth and adaptability. Whether you’re a startup or an established enterprise, OKRs can bridge the gap between aspiration and achievement, turning your vision into reality, one objective at a time.

Remember, the key to OKR success lies in consistent application, honest evaluation, and a willingness to adapt. By embracing this framework, you’re not just setting goals—you’re charting a course for organizational excellence and sustainable growth.

The Earth is one planet orbiting one star among 400 billion stars in a single galaxy, itself just one of 2 trillion galaxies in a small patch of the universe.

We are collections of atoms—some as old as time itself, others forged in stars and cooked over billions of years—arranged in patterns capable of thought. Remarkably, it is a reasonable guess that there are no other worlds in our galaxy where this has happened. If this is true, it means that our planet is the only place where complex biology exists, the only place where anything thinks, and the only place where meaning exists within our galaxy.

Paradoxically, while we are physically insignificant, this planet could be considered the most valuable place in the local universe. If we were to destroy ourselves—through deliberate action or inaction—we would be responsible for erasing meaning in a galaxy of 400 billion suns, potentially forever.

We bear an immense responsibility to preserve meaning in this galaxy. To safeguard the rare and fragile gift of thought, to protect the only known haven for consciousness, is to honor the improbability of our existence. In a cosmos vast beyond comprehension, this tiny world may be the only voice capable of telling its story; we must make it endure.

it’s possible we’re the only island of meaning in our galaxy

I used to think the top global environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought within 30 years of good science we could address those problems, but I was wrong.

The top global environmental problems are selfishness, greed and apathy—and to deal with these we need a spiritual and cultural transformation, and we scientists don’t know how to do that.

“Save the planet!”—it’s a rallying cry we’ve all heard. But does the planet really need saving?

The Earth itself is a colossal, resilient ball of rock and metal, formed 4.5 billion years ago. Its 1,086 trillion cubic kilometers of mass includes an iron-nickel core, molten mantle, and a thin crust. And life? It clings to an astonishingly tiny fraction of that—our biosphere, which makes up just 0.0007% of the planet’s volume.

Even if humanity unleashed its worst, devastating ecosystems and causing irreversible damage, Earth would endure. It has survived asteroid impacts, super-volcanoes, and eons of cosmic turbulence. Regardless of our actions, it will continue orbiting around the Sun for another 7 billion to 8 billion years.

Life Is Resilient, But We’re at Risk

Life on Earth began about 4 billion years ago, but for most of that time, it consisted of single-celled organisms. Complex multicellular life—plants, animals, and ecosystems like the ones we rely on—only appeared around 600 million years ago. That’s just 15% of life’s history.

Since then, Earth has endured five mass extinctions, each wiping out 75% to 96% of species. After every catastrophe, life found a way to recover, but not without immense loss. Microbial life, in particular, appears to be ubiquitous and almost indestructible:

• Some bacteria can survive for years in the vacuum of outer space. Others live in polar deserts, survive high temperature and pressure, and even resist radiation.
• The human body hosts more bacteria cells (38 trillion) than human ones (30 trillion).

Even if humanity were to vanish, microbial life would likely persist. But our survival—and the survival of countless species we depend on—isn’t guaranteed.

Who Really Needs Saving?

What’s at stake isn’t the planet itself—it’s our own lives. The ecosystems we depend on for food, water, and air are fragile, and their collapse puts humanity’s future in jeopardy. The Earth will endure without us, but we cannot endure without the delicate balance of life that sustains us.

Let’s stop pretending we’re here to “save the planet.” The truth is, we need to save ourselves—and to do that, we must protect the ecosystems that sustain us.

As John Doerr outlines in Speed & Scale (and reinforces in his TED Talk) a clear plan to tackle the climate crisis and build a sustainable future:

1. Electrify Transportation – Transition to clean, electric vehicles and renewable energy.
2. Decarbonize the Grid – Shift away from fossil fuels to wind, solar, and other green energy sources.
3. Fix Food – Reduce food waste and transform agricultural practices to be sustainable.
4. Protect Nature – Safeguard forests, oceans, and biodiversity.
5. Clean Up Industry – Innovate cleaner production processes for essential goods.
6. Remove Carbon – Invest in technologies to capture and store CO₂.

The Way Forward

The challenges are immense, but so is the opportunity. By taking action, we’re not just preserving our species—we’re ensuring a livable future for generations to come.

The Earth doesn’t need us to survive. But we need the Earth, its ecosystems, and the delicate balance of life to thrive. Let’s move beyond slogans and focus on what truly matters: creating a sustainable world for all.
