With widespread, sustained declines in fertility, the world population will likely peak in 2064 at around 9.7 billion, and then decline to about 8.8 billion by 2100 — about 2 billion lower than some previous estimates, according to a study.
Trade relations between Africa and Asia, especially China, increase the prosperity of African countries, according to the Kiel Institute China Initiative.
According to analysis, global warming accelerates the loss of biodiversity. Vice versa, measures to protect biodiversity may also mitigate the impacts of climate change.
The anthropogenic warming of the planet will probably have a much greater impact on worldwide production and prosperity than has been quantified by previous model studies.
The growing use of nitrogen fertilizers in the production of food worldwide is increasing concentrations of nitrous oxide in the atmosphere. The emissions are putting reaching climate goals in jeopardy.
Decarbonizing US electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A model suggests that most fossil fuel power plants could complete normal lifespans and still close by 2035 because so many facilities are nearing the end of their operational lives.
Coordinated international action on energy-efficient, climate-friendly cooling could avoid as much as 600 billion tonnes CO2 equivalent of greenhouse gas emissions in this century.
Scientists predict Greenland ice sheet will pass a threshold beyond which it will never fully regrow and sea levels will be permanently higher in as little as 600 years under current climate change projections.
Groundwater reservoirs in Bavaria have warmed considerably over the past few decades. Water found at a depth of 20 metres was almost one degree warmer on average than 30 years ago.
A shift towards hydrogen-powered mobility could significantly reduce greenhouse gas emissions and greatly improve air quality – in particular, heavy duty vehicles represent a low-hanging fruit for decarbonization of road transport.
