The first law of thermodynamics states that energy cannot be created or destroyed. This means that all cooling systems reject heat as they work by removing heat from a medium in a given space. What prevents us from using this rejected heat for direct thermal applications is that the temperature is too low to be useful. The low temperature of rejected heat from cooling systems requires us to use an energy consuming heat pump to upgrade the heat to a temperature that is suitable for direct thermal applications. What if instead we choose to redesign cooling systems to reject heat at higher temperatures so that could avoid the energy penalty of a heat pump.

If we choose to pursue this in the future then we will end up making cooling systems dual use

1. They provide cooling for refrigeration, air conditioning, gas liquefaction etc

2. They produce usable heat for direct thermal applications

This could eliminate the need for separate cooling and heating systems.

If we pursue this then it will have the following benefits

1. Elimination of natural gas for direct thermal applications

2. Reduction of freshwater consumption by cooling towers to reject heat from cooling systems in industrial applications

3. Elimination of all the costs associated with having cooling and heating systems being two separate systems

4. Reduction of energy cost

Improving cooling systems to reject heat at higher temperatures will enable rejected heat from cooling systems to work as a decarbonization solution.

The effect of climate change on rising sea level was underestimated. This is just another case against emissions.

But the post asks a question on whether only policy measures can be effective in reducing CO2. What do you think? Do we need to look at our consumption pattern to realibly reduce CO2?

One of the consequences of climate change

Overestimated natural biological nitrogen fixation translates to an exaggerated CO2 fertilization effect in Earth system models by Sian Kou-Giesbrecht, Carla R. Reis Ely, Steven S. Perakis, and Nina Wurzburger.

In brief, the Earth system models, including climate models used in the IPCC report, have overestimated by about 11% the degree by which wild plants growth improves under higher CO2 aka CO2 fertilization. Although 11% does not sound huge, this shall significantly decrease the effects of land carbon sinks.

There is a video discussion at https://www.youtube.com/watch?v=ywxdWD6NqE8 which brings up some related work, including one paper that suggests methods for improving nitrogen bio-availability in natural eco-systems, but this paper says known methods appears highly ecosystem dependent.

The only real solution to climate change is to restore Earths climate to its pre-industrial state. This is to be done by removing CO2 from Earths atmosphere once carbon neutrality has been established. We will need to first establish carbon neutrality by transitioning from fossil fuels to non-intermittent carbon neutral energy sources. After than we will need to use a carefully planned portfolio of CDR methods to return atmospheric CO2 to 280 PPM. We need to restore Earths climate if we choose to care about human civilization and the natural environment.

Here are the CDR methods we should use to restore atmospheric CO2 to 280 PPM once carbon neutrality is established

1. Regenerative agriculture

2. Biochar

3. Enhanced Rock Weathering

4. Turning fire prevention thinning waste into bio-oil and injecting this oil underground - https://heatmap.news/technology/charm-forest-service-carbon-removal

5. Wastewater Alkalinity Enhancement

6. Killing and sinking harmful algae blooms - https://carbonherald.com/first-ever-carbon-credits-from-toxic-algal-remediation-are-issued/

Direct air capture should not be used because it is energy intensive and does not have any co-benefits besides CDR.

All of the CDR methods listed above will need to be implemented at the same time acorss the entire world in order to restore Earths climate. We will likely need to use all six methods for at least 50-100 years in order to return atmospheric CO2 back to 280 PPM. In the meantime these CDR methods will each have their own co-benefits other than CDR which will make than beneficial to society rather than loss making activities.

Absolute restoration of Earths climate its the only acceptable climate action strategy if we truly care about present and future generations. We must accept that restoration of Earths climate is not a simple task but it need to be done to undo the mistakes of our past. If we reuse to fix the mistakes of our past then we will be betraying present and future generations whose quality of life will inevitably deteriorate due to climate change. We need to stop thinking according to the short termist plan of mitigation and adaption and start actual climate action.

At ReduceCO2Now, we've been experimenting with a different approach to recruiting.

We no longer conduct traditional job interviews.

Instead, we invite people to join our project meetings, collaborate with the team, and experience the project firsthand. The recruitment process itself becomes a practical test of motivation, teamwork, communication, reliability, and initiative.

Over time, we've collected data from more than 2,000 applicants from around the world.

Now we have an important question:

What can we learn from this data?

We're looking for:

• University professors
• PhD researchers
• Master's students conducting research
• Experts in organizational psychology
• HR researchers
• Industrial and organizational psychologists
• Data scientists interested in people analytics

Possible research topics include:

• Do interviews actually predict success?
• Which applicant characteristics correlate with long-term contribution?
• Can work samples outperform interviews?
• How can volunteer organizations improve recruiting?
• What predicts engagement, retention, and performance?

We believe many organizations still rely heavily on interviews despite growing evidence that structured assessments and work samples may be stronger predictors of future performance.

If you are interested in helping analyze this unique dataset, we'd love to hear from you.

Let's use data to improve how organizations identify talent and create opportunities.

It's a simple question.

Do you want your children, grandchildren, nieces, nephews, and future generations to inherit a world where they can thrive?

A world with stable food supplies.
A world where extreme heat, droughts, floods, and wildfires are not constant threats.
A world where nature still exists beyond photographs and history books.

Most people would answer "yes" without hesitation.

The challenge is that the future is being shaped right now. Every year of delay increases the risks and makes solutions more difficult and more expensive.

The good news is that we already know a lot about the problem. We have talented people, scientific knowledge, engineering capability, and the ability to organize global action.

What we need is enough people who care and are willing to help.

So today's question is:

What do you think we should do to create a world that remains usable for future generations?

The greenhouse effect is one of the reasons life exists on Earth.

Without it, our planet would be far too cold for humans, animals, and plants. Greenhouse gases act like a blanket around the Earth, trapping some of the Sun's heat and keeping temperatures suitable for life.

The problem is not the greenhouse effect itself.

The problem is that humans are making that blanket thicker.

By burning coal, oil, and gas, we have increased the concentration of CO₂ in the atmosphere from about 280 ppm before the Industrial Revolution to more than 430 ppm today. This extra CO₂ traps additional heat that would otherwise escape into space.

The result:

• Rising global temperatures
• More frequent heatwaves
• Melting glaciers and ice sheets
• Rising sea levels
• Changing rainfall patterns
• Increased risk of extreme weather events

Think of it this way:

A blanket keeps you warm on a cold night. Add a second blanket and you get warmer. Add a third, fourth, and fifth blanket, and eventually you become uncomfortably hot.

That is essentially what we are doing to our planet.

The science behind the greenhouse effect has been understood for more than a century. What has changed is the amount of greenhouse gases we are putting into the atmosphere.

The good news is that the same actions that reduce CO₂ emissions can slow the warming. Every ton of CO₂ we avoid helps reduce future temperature increases.

The challenge is large, but the solutions already exist.

What do you think is the most effective way to reduce greenhouse gas emissions globally?

Over the last months, we have been researching volunteer recruitment and team building for climate projects.

Like many organizations, we started with traditional interviews. We wanted to understand people's skills, motivation, and fit for the team.

Then we tried something different.

We stopped doing job interviews.

Instead, we invite interested people to join our project meetings directly.

They see the real project.
They meet the real team.
They experience how we work.
And we get to see how they collaborate, communicate, contribute ideas, and interact with others.

The results have been surprising.

Some people who interviewed extremely well contributed very little once they joined a project.

Others who might never have impressed in a formal interview became highly valuable team members.

We are currently analyzing the data and looking for someone interested in helping us evaluate our findings.

If you have experience in:
• Psychology
• Human Resources
• Organizational Development
• Statistics
• Data Analysis
• Recruitment Research

we would love to hear from you.

We believe there may be lessons here that apply far beyond climate projects.

Are job interviews still the best way to select people, or should organizations focus more on observing people in real work situations?

When people hear that Earth has warmed by about 1.5°C since pre-industrial times, many assume that is what they experience where they live.

In reality, much of the world's population lives on land, and land areas are warming significantly faster than the global average.

The graph from the German Weather Service (DWD) shows a striking example:

• Global average warming: about +1.5°C
• Germany's warming: about +3°C

Why the difference?

About 70% of Earth's surface is covered by oceans. Water absorbs and stores enormous amounts of heat, which slows temperature increases over the oceans.

Land behaves differently. It heats up faster and cools down faster. As a result, countries and regions dominated by land often experience warming rates that are far above the global average.

Germany is not unique.

Scientists observe similar patterns across Europe, North America, Asia, Africa, and many other regions. In many places, people are already experiencing temperature increases that are close to double the global average.

This is important because agriculture, water supplies, ecosystems, infrastructure, and human health are all directly affected by local temperatures, not by the global average alone.

Climate change is a global phenomenon, but its impacts are often felt most strongly on land where people live.

The scientific evidence for human-caused climate change is stronger today than at any point in history. We can measure rising CO₂ levels, increasing global temperatures, melting ice, rising sea levels, and changes in weather patterns around the world.

Yet many people still reject or question the idea that humans are the main cause.

Why?

There are many possible reasons:

• Climate change challenges habits and lifestyles that people are comfortable with.
• Accepting the problem may feel like accepting personal responsibility.
• Some people distrust governments, corporations, media, or scientists.
• The impacts often seem distant until they affect us directly.
• Climate science is complex, and misinformation spreads quickly online.
• Many people simply do not realize how strong the scientific evidence has become.

Human psychology plays a role too. We often underestimate slow-moving threats and prefer information that confirms what we already believe.

What do you think?

Why do some people deny or reject human-caused climate change despite the growing evidence?

When people hear that the Earth has warmed by about 1.3°C since the late 19th century, many assume that means temperatures have increased by roughly the same amount everywhere.

They haven't.

Because oceans absorb and redistribute large amounts of heat, land areas warm much faster than the global average. Since about 70% of our planet is covered by water, the global average temperature increase hides what people actually experience where they live.

Germany is a striking example.

According to data from the German Weather Service (DWD), Germany has already warmed by around 2.5°C since 1881. That is nearly double the global average warming.

This difference matters because most people, agriculture, infrastructure, and ecosystems are located on land. The warming we experience in our daily lives is therefore often much greater than the number reported for the planet as a whole.

The consequences are becoming increasingly visible:

• More frequent and intense heatwaves
• Higher nighttime temperatures that reduce recovery from heat stress
• Increased drought risk and pressure on agriculture
• Greater risk of extreme rainfall and flooding events
• Growing impacts on ecosystems and biodiversity

Global warming is not a future scenario. It is already measurable in Germany and across many other land regions around the world.

The good news is that the causes are well understood, and we already have many of the technologies needed to reduce emissions and stabilize the climate. Every tonne of CO₂ avoided reduces future warming.

WARNING

This graph shows 570 million years. It is cited often from climate change deniers.

Look at the heavily skewed timescale.

It gives CO2 on a scale up to 8000 ppm. That is 20 times the current values and makes the CO2 changes seem small.

The temperature scale is not even visible (there are only some arrows on the left side; it is probably around 15-20°C).

Screenshot taken from https://capitalresearch.org/article/the-global-warming-scam-part-2/

The graph shows the global mean temperature shows global warming.

Since the 1960s global temperatures are on a constant rise!

REMEMBER: Warming on LAND can be nearly DOUBLE that of the global warming (as the planet is mostly water).

https://wmo.int/news/media-centre/wmo-confirms-2025-was-one-of-warmest-years-record

Germany has recorded a nighttime temperature of 29.4°C, one of the highest overnight temperatures ever measured in the country.

Nighttime heat matters. Our bodies, homes, infrastructure, and ecosystems depend on cooler nights to recover from daytime temperatures. When temperatures remain extremely high after sunset, heat stress increases significantly.

This is exactly what climate scientists have warned about for decades.

Global average temperature has increased by about 1.3°C since pre-industrial times. Because oceans absorb much of the heat, warming over land is significantly higher. In many regions, including Europe, land temperatures have risen roughly twice as much as the global average.

The underlying driver is clear. Human activities have increased atmospheric CO₂ concentrations from about 280 ppm before the Industrial Revolution to more than 430 ppm today.

NASA ice core records show that for hundreds of thousands of years, CO₂ remained within a relatively stable range. We have now pushed far beyond that historical range, and the climate system is responding.

Heat waves that once seemed exceptional are becoming more frequent, more intense, and longer-lasting.

The good news is that we still have choices. Every ton of CO₂ we avoid emitting reduces future warming. Every solution we scale helps.

Regenerative agriculture is absolutely necessary if we want to adress climate change. We will need regenerative agriculture to protect our food supply from the effects of climate change in the immediate term. In the long term we will need regenerative agriculture to remove CO2 from the atmosphere and sequester it in soil so that atmospheric CO2 can be restored to 280 PPM. Regenerative agriculture cannot happen without cover cropping. We need to decide what crops to grow as cover crops in order to scale regenerative agriculture

One type of crop which we could grow as cover crops are oilseeds. Oilseeds are plants which naturally produce lipids and store them in there seeds. These plants do this to give their seeds a supply of energy for initial growth before photosynthesis can start. We can tap these lipids and use them to produce liquid fuels. The best way to do this without causing the indirect land use change is by growing such crops as cover crops. Cover crops are by definition grown on existing agricultural land in order to protect the soil during the off season.

Here are the criteria for determining if a oilseed plant can work as a cover crop

1. Effectiveness at cover cropping in terms of soil health impact

2. Oil content (30% is a good baseline to ensure efficiency)

3. Wether of not the oil is edible or inedible to humans (inedible for biofuel)

If a oilseed crop meets all three of these criteria then it can be utilized as a cover crop with valorization of the seed oil after start of season harvesting

Crushing the seeds from these crops does not just yield oil. A solid material known as oilseed meal is also produced. This oilseed meal can be fed to livestock which in turn produces meat, dairy and eggs for human consumption. The wastewater produced during the crushing process should be anaerobically digested on site to produce biogas for use as fuel to produce the heat needed for the crushing process.

Here are some examples of oilseeds which can be used as cover crops

1. Camelina - https://en.wikipedia.org/wiki/Camelina

2. Carinata - https://en.wikipedia.org/wiki/Brassica_carinata

3. Pennycress - https://en.wikipedia.org/wiki/Thlaspi

These oilseed crops are currently undergoing extensive research to see how well they can function as both cover crops and biofuel feedstocks.

Here is the idealized production pathway for biofuels from oilseed cover crops

1. The Seeds are crushed with oil being sold off as biofuel feedstock and meal being sold as animal feed

2. Seed oil undergoes cleaning, enzymatic degumming and enzymatic selective hydrolysis to make it suitable for pipeline transportation with the wastewater produced from this process being used to produce biogas to be burned to produce the heat needed by the process

3. Seed oil is transported by pipeline like crude oil to large centralized biofuel production facilities

4. These facilities use bimetallic catalytic reactors to hydrodeoxygenate the seed oils using hydrogen produced via self powering steam reforming of the bio-LPG byproduct

(The steam reformers are self powered via there own carbon monoxide output and also use bimetallic catalysts to reduce energy demand)

1. The diesel and jet fuel produced by this process are sold on the existing liquid fuels market
   

A future cover crop oilseed economy will be a multi step system.

Growing oilseeds as cover crops will be a significant boast to both decarbonization and CDR. We would be able to enable soil carbon removal while at the same time producing carbon neutral liquid fuels to replace fossil fuel derived liquid fuels. The cultivation of oilseeds as cover crops should be considered a foundational aspect of climate action.

France: France recorded its hottest day on record on 24 June - beating the record set the previous day - with an average national temperature of 30.0° Celsius, above previous records set in July 2019 and August 2003, said Metéo-France. Temperatures rose up to 43.8 °C in the town of Pulluau in western France. Overnight temperatures also set a new national record of 22 °C.  

A top-level Red Alert was issued for a record 58 departments - most of the country. Authorities warned of a high risk of wildfires amid a worsening drought. Underlining the associated dangers with the life-threatening heat, 40 people reportedly died in drowning accidents in France.  

Spain recorded its hottest June days on record on 23 and 24 June. In a number of locations, temperatures were well above 40°C, setting many new June station temperature records,  according to the Agencia Estatal de Meteorologia, AEMET. The city of Bilbao reached 42.7°C, the highest June temperature recorded there. 

The United Kingdom broke the June temperature record for three consecutive days, with  36.4 °C recorded in southern England on 25 June –  a provisional figure which was likely to be revised upwards. The UK’s Met Office issued Red Warnings for Extreme Heat once again for 26 June – the first time in the history of the current weather warnings system that red warnings have been issued for three straight days.  

This comes just weeks after May also saw UK daily temperature records broken. 

Germany also was under widespread Red Warnings issued by the national weather service, the Deutscher Wetterdienst, including for the capital Bonn and cities of Frankfurt and Cologne.  

In the Netherlands, the Dutch national meteorological service, KNMI, issued an unprecedented Red Alert for extreme heat for eight provinces for 26 June for 26 June, and reported a number of  new station records. 

Switzerland set a new June temperature record of 38°C in the northern city of Basel, according to Meteo-Suisse.
