A related phenomenon driven by climate change is woody plant encroachment, affecting up to 500 million hectares globally. [218] Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [219] The size and speed of global warming is making abrupt changes in ecosystems more likely ...
Renewable energy records have been set, the world celebrated one of its greatest environmental wins and countries made a cautious but historic step towards a fossil fuel-free future. Here are five ...
Most respondents to a climate survey conducted in 2021-2022 by the European Investment Bank say countries should back renewable energy to fight climate change. [ 261 ] The same survey a year later shows that renewable energy is considered an investment priority in the European Union, China and the United States [ 262 ]
If we stay with fossil fuels and only slowly creep toward renewable energy systems, climate change will become more costly to all of us. Climate change must speed our use of renewable energy ...
Renewable energy sources, especially solar photovoltaic and wind power, are providing an increasing share of power capacity. [42] The competitiveness of renewable energy is a key to a rapid deployment. In 2020, onshore wind and solar photovoltaics were the cheapest source for new bulk electricity generation in many regions. [43]
100% renewable energy is the goal of the use renewable resources for all energy. 100% renewable energy for electricity, heating, cooling and transport is motivated by climate change, pollution and other environmental issues, as well as economic and energy security concerns.
