Answer:
As concentrations of greenhouse gases have increased, the Earth has warmed
From 1906-2005, the average global temperature rose by 0.74ºC, with most of that warming occurring since 1970. By 2015, the average global temperature had warmed by over 1ºC since pre-industrial times. Sixteen of the 17 warmest years on record have been in 21st century.
This warming isn't the same everywhere. Some areas with crucial ecological importance - like around the poles - are warming at two or three times the global average.
This climate change is because of human activity
The main causes of climate change are:
Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry
Deforestation – because living trees absorb and store carbon dioxide
Increasingly intensive agriculture – which emits greenhouse gases like methane and nitrous oxide
