In this article, "climate change" means a change in climate that persists over a sustained period of time.[6][7] The World Meteorological Organization defines this time period as 30 years.[6] Examples of climate change include increases in global surface temperature (global warming), changes in rainfall patterns, and changes in the frequency of extreme weather events. Changes in climate may be due to natural causes, e.g., changes in the sun's output, or due to human activities, e.g., changing the composition of the atmosphere.[8] Any human-induced changes in climate will occur against the "background" of natural climatic variations.[8]
Also, the term "anthropogenic forcing" refers to the influence exerted on a habitat or chemical environment by humans, as opposed to a natural process.[9]
Temperature changes
Since there isn't AGW there isn't any affect.
However, plants do like warmer weather. How many trees do you see in Antarctica compared to the tropics or the jungles of Africa.
They also like CO2. So drive you car more often.
Increases in atmospheric CO2 concentration for affect how plants photosynthesise, resulting in increases in plant water use efficiency, enhanced photosynthetic capacity and increased growth. Increased CO2 has been implicated in ‘vegetation thickening’ which affects plant community structure and function. Depending on environment, there are differential responses to elevated atmospheric CO2 between major ‘functional types’ of plant, such as C3 and C4 plants, or more or less woody species; which has the potential among other things to alter competition between these groups. Increased CO2 can also lead to increased Carbon : Nitrogen ratios in the leaves of plants or in other aspects of leaf chemistry, possibly changing herbivore nutrition.
Compare the vegetation at the poles and then in the tropics and I think you will find the answer.
The effect was very good.
Bumper crops WORLDWIDE has been the result of the slightly warmer weather along with the CO2 enriched atmosphere. Of course the advocates of man-made Global Warming try to deny this fact, but the evidence is overwhelming.

Many Bumper crops reported worldwide, while Warmists try to say crops are failing

With warmer weather, increased CO2 and plentiful rainfall, one would expect a dramatic increase in food production and that is exactly what has happened.
But of course Warmists are crestfallen over this fact because their narrative does not allow any good news in connection to their catastrophic man-made Global Warming scam.
I have many more links to reports of Bumper Crops Worldwide, if you want more just ask.
