If today’s planetary ecological emergency is a product of centuries of war on the planet as a mechanism of capital accumulation, fossil-capital generated geoengineering schemes can be seen as gargantuan projects for keeping the system going by carrying this war its ultimate level.

This year marks the twentieth anniversary of the foundation in Portugal of the Bloco de Esquerda (BE, Left Bloc), which was created as a unique political movement and not as a unified political party or as a coalition. Its constitution and evolution, for those of us who have closely followed this experience with interest and passion from other political contexts, is paradigmatic. A unique experience that is not free of paradoxes, challenges and risks. A revolutionary left that does not want to limit itself to a testimonial practice and self-affirmation has to reflect on these.
