"Here we analyse 35 years’ worth of satellite data and provide a comprehensive record of global land-change dynamics during the period 1982–2016. We show that—contrary to the prevailing view that forest area has declined globally—tree cover has increased by 2.24 million km2 (+7.1% relative to the 1982 level). This overall net gain is the result of a net loss in the tropics being outweighed by a net gain in the extratropics."
"They further report that much of the new growth came about due to efforts by humans (such as reforestation efforts in China and parts of Africa) and because of global warming—warmer temperatures have raised timberlines in some mountainous regions, and allowed forests to creep into tundra areas. Other areas of new tree growth resulted from large farm abandonments in places like Russia and the U.S. The researchers report that their calculations showed that human activities have directly caused approximately 60 percent of new global tree growth. They suggest their technique for monitoring tree cover could be used to predict tree cover changes in the future due to global warming."
So reforestation efforts led by humans has contributed to this change. AND global warming caused by humans has caused the tundra to warm up enough that forests have moved up there.
Interesting, but one could easily read this as being "Nature will heal itself, we don't need to do anything".
That's not quite what's happening of course. Nature will adapt to whatever changes, and that may bring things back to the way they were. Or it may take off in a completely different direction - possibly one unsuitable for us.
"Moore co-chaired the Clean and Safe Energy Coalition, which was supported by the Nuclear Energy Institute, a national organization of pro-nuclear industries.[59] In 2009, as co-chair of the Coalition, he suggested that the mainstream media and the environmentalist movement is not as opposed to nuclear energy as in decades past.[59]
He argues that any realistic plan to reduce reliance on fossil fuels or greenhouse gas emissions would require increased use of nuclear energy to supply baseload power."
IPCC is a governmental lobby indeed that's why governmental reviewers have the final word on what appears in the report (Article 11 of IPCC legal statuses).

Human, an fascinating animal yet with such a high opinion of itself.
