Newly published IPCC report, “Climate Change and Land”:

Some excerpts:

A 2. Since the pre-industrial period, the land surface air temperature has risen nearly twice as much as the global average temperature (high confidence). Climate change, including increases in frequency and intensity of extremes, has adversely impacted food security and terrestrial ecosystems as well as contributed to desertification and land degradation in many regions (high confidence). {2.2, 3.2, 4.2, 4.3, 4.4, 5.1, 5.2, Executive Summary Chapter 7, 7.2}...

A 5. Climate change creates additional stresses on land, exacerbating existing risks to livelihoods, biodiversity, human and ecosystem health, infrastructure, and food systems (high confidence). Increasing impacts on land are projected under all future GHG emission scenarios (high confidence). Some regions will face higher risks, while some regions will face risks previously not anticipated (high confidence). Cascading risks with impacts on multiple systems and sectors also vary across regions (high confidence). {2.2, 3.5, 4.2, 4.4, 4.7, 5.1, 5.2, 5.8, 6.1, 7.2, 7.3, Cross-Chapter Box 9 in Chapter 6, Figure SPM.2}...

D3.2. In future scenarios, deferral of GHG emissions reductions implies trade-offs leading to significantly higher costs and risks associated with rising temperatures (medium confidence). The potential for some response options, such as increasing soil organic carbon, decreases as climate change intensifies, as soils have reduced capacity to act as sinks for carbon sequestration at higher temperatures (high confidence). Delays in avoiding or reducing land degradation and promoting positive ecosystem restoration risk long-term impacts including rapid declines in productivity of agriculture and rangelands, permafrost degradation and difficulties in peatland rewetting (medium confidence). {1.3.1, 3.6.2, 4.8, 4.9, 4.9.1, 5.5.2, 6.3, 6.4, 7.2, 7.3; Cross-Chapter Box 10 in Chapter 7}

This is a political document to try to pressure the Trump administration to do something about climate change.  The solutions to go renewable are very damaging not only to the world economic system but also the environment. Wind farms ruin wild forests and fields, kill birds and bats. Solar farms use up precious land that was once wild. The insanity is destroying our environment. Given that the Earth was warmer 6000-8000 years ago and our wildlife survived, I don't think a little warming over century long time scales would do any harm if it happens, nature will adapt to slow changes. It always has and always will....  I have to turn off the email notifications from this site. This stuff is just insanity. I'm done with this.

The IPCC’s existence predates the Trump Administration. Its work predates it. The report was not prepared specifically for the Trump Administration. It was prepared for all global policy makers and relevant stakeholders. It is very likely that the IPCC will also continue to exist long after the Trump Administration has ended, as much of the world accepts the findings of climate science and finds the body, which summarizes and draws upon that large and growing body of work, to be useful.
