A short glossary of the changes we’ve made to the Guardian’s style guide, for use by our journalists and editors when writing about the environment

Net-zero targets imply that continuing residual emissions will be balanced by carbon dioxide removal. However, residual emissions are typically not well defined, conceptually or quantitatively. We analysed governments’ long-term strategies submitted to the UNFCCC to explore projections of residual emissions, including amounts and sectors. We found substantial levels of residual emissions at net-zero greenhouse gas emissions, on average 18% of current emissions for Annex I countries. The majority of strategies were imprecise about which sectors residual emissions would originate from, and few offered specific projections of how residual emissions could be balanced by carbon removal. Our findings indicate the need for a consistent definition of residual emissions, as well as processes that standardize and compare expectations about residual emissions across countries. This is necessary for two reasons: to avoid projections of excessive residuals and correspondent unsustainable or unfeasible carbon-removal level

The eyes of history will pierce the fog of politics. Science has exposed the course upon which our quest for energy has set our planet. Consequences will fall mainly on young people, their children, and grandchildren — unless decisive political leadership abandons wishful thinking and superficial half-measures. Climate change is a global matter and demands a global perspective.

There is a myth about human beings that withstands all evidence. It’s that we always put our survival first. This is true of other species. When confronted by an impending threat, such as winter, they invest great resources into avoiding or withstanding it: migrating or hibernating, for example. Humans are a different matter.

Dangerous climate change has arrived and at this point it’s simply a matter of how bad we’re willing to let it get. But you don’t need to give yourself a guilt trip about it. Save that for the fossil fuel executives.

China's carbon emissions are vast and growing, dwarfing those of other countries. Experts agree that without big reductions in China's emissions, the world cannot win the fight against climate change. While all countries face problems getting their emissions down, China is facing the biggest challenge.
