For anyone who needs clear, detailed, well-evidenced information about global warming, this is an outstandingly useful book. ‘. . . an excellent basis for students and non-scientists to understand climate change with its manifold impacts and consequences for humankind and for our common planet.
2.1 Observed Changes, Impacts and Attribution Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850–1900 in 2011–2020. Global greenhouse gas emissions
This effect is called the greenhouse effect, and these heat-trapping gases are called greenhouse gases. The greenhouse effect is a natural process that makes the Earth liveable for humans: without the natural greenhouse effect, the global average temperature would be about 33ºC (59°F) colder.
Highlights of the IPCC Fifth Assessment Report. IPCC AR5 Synthesis Report. Key Messages. Human influence on the climate system is clear. The more we disrupt our climate, the more we risk severe, pervasive and irreversible impacts. We have the means to limit climate change and build a more prosperous, sustainable future.
There are two main ways to stop the amount of greenhouse gases from increasing: we can stop adding them to the air, and we can increase the Earth’s ability to pull them out of the air. This is called climate mitigation. There is not one single way to mitigate climate change.
An IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
