The climate crisis is blamed on several human activities, but the biggest contributor to climate change is the increase in the greenhouse effect produced by carbon dioxide (CO2), among other harmful gases.
Most of the current carbon dioxide emissions come from burning fossil fuels. The main reason we burn fossil fuels is to generate energy.
To fight climate change, we need to find a new way of getting clean energy.
Seeds open a unique possibility for us, regular citizens, to decentralize energy generation and ensure a sustainable future.
We need you to be part of one of the most important, social, and economic changes in modern history.
There are many roads to this single goal, reducing emissions.
Now it is up to you to decide.
Knowledge is power!
Facing the harsh truth
Facts about our planet's health
The Earth's climate has changed throughout history. But this should not be used as a pretext for denying the undeniable. Human activity is driving climate change, including global temperature rise.
The graph below shows the earth's CO2 levels over the last seven glacial cycles. The last ice age ended about 11.000 years ago, marking the beginning of the modern climate era and of human civilization.
If it is not clear on the graph, we humans appeared when the CO2 line started to grow exponentially.
To come to a scientific conclusion on climate change and what to do about it, the United Nations in 1988 formed a group called the Intergovernmental Panel on Climate Change, or IPCC.
The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming. Each report represents a consensus, or agreement, among hundreds of leading scientists.
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. There is no question that increased levels of greenhouse gases cause the earth to warm in response. Rising temperatures in the atmosphere and ocean are contributing to the continuous mass loss from Greenland and Antarctica and to increases in some extreme weather events, such as heatwaves, wildfires, rising seas, intense precipitation, shifting wildlife populations and habitats, and a range of other impacts.
