The IPCC compiles scientific insights on climate change, informing policymakers and the public about risks and possible actions. In essence, combined with climate models, they provide a way to envision the consequences of different actions or inactions. What Are Future Climate Scenarios? Lower-emission scenarios (SSP1-2.6)

Instead, a significant portion of the water taken from underground flows off the land through rivers and on to the oceans. Moisture lost to evaporation and drought, plus runoff from pumped groundwater, now outpaces the melting of glaciers and the ice sheets of either Antarctica or Greenland as the largest contributor of water to the oceans.

Of course, an honest assessment of the latest climate science will show that since 2009 the evidence has become even more compelling and dire. Climate change, driven by rising heat-trapping emissions, is already causing significant harm to peoples health and well-being and to vital ecosystems.

Behind these individual instances of harm is a clear strategy: they want to bury the scientific evidence of the impacts and economic damages caused by climate change to avoid having to take any action to address them.
