Many changes due to past and future greenhouse gas emissions are irreversible for centuries to millennia, especially changes in the ocean, ice sheets and global sea level
it can and will get worse if we continue on the same or similar trajectory
The report, which is the first major review of its kind since 2013, was released on Monday by the Intergovernmental Panel on Climate Change (IPCC) ahead of the COP26 summit in November.
U.N. SECRETARY GENERAL ANTONIO GUTERRES:
"Today's IPCC Working Group 1 Report is a 'Code Red' for humanity ... This report must sound a death knell for coal and fossil fuels, before they destroy our planet."

Nations have delayed curbing their fossil-fuel emissions for so long that they can no longer stop global warming from intensifying over the next 30 years, though there is still a short window to prevent the most harrowing future, a major new United Nations scientific report has concluded.
Even if nations started sharply cutting emissions today, total global warming is likely to rise around 1.5 degrees Celsius within the next two decades, a hotter future that is now essentially locked in.
At 1.5 degrees of warming, scientists have found, the dangers grow considerably. Nearly 1 billion people worldwide could swelter in more frequent life-threatening heat waves. Hundreds of millions more would struggle for water because of severe droughts. Some animal and plant species alive today will be gone. Coral reefs, which sustain fisheries for large swaths of the globe, will suffer more frequent mass die-offs.
"There's no going back from some changes in the climate system," said Ko Barrett, a vice-chair of the panel and a senior adviser for climate at the National Oceanic and Atmospheric Administration.
humanity can still prevent the planet from getting even hotter. Doing so would require a coordinated effort among countries to stop adding carbon dioxide to the atmosphere by around 2050, which would entail a rapid shift away from fossil fuels starting immediately, as well as potentially removing vast amounts of carbon from the air. If that happened, global warming would likely halt and level off at around 1.5 degrees Celsius, the report concludes.
