Explainer: Desertification and the role of climate change - Carbon …
WEBAug 6, 2019 — Desertification has been described as “the greatest environmental challenge of our time” and climate change is making it worse. While the term may bring to mind the windswept sand dunes of the Sahara or the vast salt pans of the Kalahari, it’s an issue that reaches far beyond those living in and around the world’s deserts, threatening the food security and livelihoods of more than two ...
Explainer: How ‘Shared Socioeconomic Pathways’ explore future …
WEBApr 19, 2018 — Narratives for each Shared Socioeconomic Pathway, from Riahi et al 2017.. These narratives describe alternative pathways for future society. They present baselines of how things would look in the absence of climate policy, and allow researchers to examine barriers and opportunities for climate mitigation and adaptation in each possible future world when combined with mitigation targets.
Met Office: Atmospheric CO2 now hitting 50% higher than pre …
WEBMar 16, 2021 — Carbon dioxide (CO2) in the atmosphere is now reaching levels 50% higher than when humanity began large-scale burning of fossil fuels during the industrial revolution.. Recent measurements from the Mauna Loa observatory in Hawaii show that for several days in February and March 2021, atmospheric CO2 levels exceeded 417 parts per million (ppm). Pre-industrial levels were about 278ppm.

Explainer: The high-emissions ‘RCP8.5’ global warming scenario
WEBAug 21, 2019 — A sizable portion of recent studies on future climate impacts have focused on a future warming scenario called “RCP8.5”. This high-emissions scenario is frequently referred to as “business as usual”, suggesting that is a likely outcome if society does not make concerted efforts to cut greenhouse gas emissions.
Factcheck: How electric vehicles help to tackle climate change
WEBMay 13, 2019 — Electric vehicles (EVs) are an important part of meeting global goals on climate change. They feature prominently in mitigation pathways that limit warming to well-below 2C or 1.5C, which would be inline with the Paris Agreement’s targets.
