Science may have found an answer to reduce global warming.
Over the past three decades, we have seen the climate crisis develop from a concern for future generations into an immediate worry for life on our planet. We now understand that pulling carbon out of the air we breathe may change rainfall patterns.
How can plants hold the key to solving global warming?
What measures have we undertaken so far to address climate change
For one, we are attempting to decarbonize the entire international energy sector over the coming years.
International energy production has, without a doubt, been one of the worst contributors to global warming. Our collective need for energy to power our daily lives has led us down a very dark road indeed.
As of early 2026, up to 194 countries have reaffirmed their commitments to the Paris Agreement.
National legislation is also changing to reflect the current climate crisis we face. The South African government implemented a new policy in 2024 that mandates sectoral emission targets and carbon budgets for large companies.
The world is speaking to us, so we’d better listen up or face a perilous future
Harmful carbon emissions are getting out of hand, and the planet is warning us through the multitude of significant weather disasters that have emerged recently.
The impact of climate change has become too loud to ignore in recent years. Such as the fact that tropical peatland fires have reached astonishing levels not seen in a very long time.
And the result of our devastation of the planet is hitting much closer to home in recent months.
The NOAA has been issueing weather related warnings like a house with too much candy on Halloween. It noted that the tornado season in the United States has started earlier this year.
So, what can be done to alleviate concerns about the climate crisis we are currently facing?
Photosynthesis is the process whereby plants produce oxygen by consuming carbon, but what will the long-term effects of reducing carbon in our atmosphere be on the planet?
One study has found a few interesting answers to this burning question.
We know that our atmosphere has too much carbon in it. What would happen to our planet if we reduced the levels of carbon in the air we breathe? A study, “Negative CO2 emissions for long-term mitigation of extremes in land hydrological cycle,” published in Nature, has enabled us to understand the effects.
The long-term effects of carbon reduction have been explained
With the recent wildfires and substantial risks of rainfall and flooding that swept through the nation recently in the front of our minds, a study published in Nature Communications has detailed what happens when we remove or reduce the amount of carbon in the air around us.
Earth needs a delicate balance of having enough oxygen for us as humans to breathe, and enough carbon in the air for plant life to conduct photosynthesis.
So what are the implications that arise when we remove vast quantities of carbon from the air? For one, plants that produce the oxygen needed for our world to continue to thrive have been found to open their stomata wider than normal to facilitate photosynthesis.
The result of this increase in “breathing” by plants is that they release far more water vapour into the atmosphere.
So what’s the problem, you might be asking? Well, the plants producing more water vapour mean that our planet’s rainfall patterns are altered, resulting in a projected increase in global precipitation by up to 2.5%.
This could both benefit us and raise concerns.
Increased rainfall could help address the issue of lakes around the world drying up, but could also play a role in the catastrophic weather events that have become an all too common occurrence recently.
