Earth to warm up to 2.9C even with current climate pledges

Countries’ greenhouse gas-cutting pledges put Earth on track for warming far beyond key limits, potentially up to a catastrophic 2.9 degrees Celsius this century, the UN said Monday, urging G20 nations to boost emissions cuts.The 2015 Paris Agreement saw countries agree to cap global warming at “well below” 2C above preindustrial times — with a safer limit of 1.5C if possible.Under the Paris deal, countries are required to submit ever deeper emission cutting plans, known as Nationally Determined Contributions, or NDCs.
