There have long been claims that some unspecificed "they" has "changed the name from 'global warming' to 'climate change'".
In this sense, especially in the context of environmental policy, the term climate change has become synonymous with anthropogenic global warming.

While geologists have studied events in the past similar to what appears to be happening today, scientists are largely unsure of what lies ahead.
Geochronology: the study of isotope geology specifically toward determining the date within the past of rock formation, metamorphism, mineralization and geological events (notably, meteorite impacts).

If we double atmospheric carbon dioxide[…] we’d only raise global surface temperatures by about a degree Celsius.
At current emission rates, temperatures could increase by 2 °C, which the United Nations' Intergovernmental Panel on Climate Change (IPCC) designated as the upper limit to avoid "dangerous" levels, by 2036.

IPCC overestimate temperature rise
The IPCC (2007) estimates that the expected rise in temperature due to a doubling of CO2 to be about 3 °C (5.4 °F), ± 1.5°.

"Austria is today seeing its earliest snowfall in history with 30 to 40 centimetres already predicted in the mountains.
Although Austria is cold in the winter (−10 to 0 °C), summer temperatures can be relatively high, with average temperatures in the mid-20s and a highest temperature of 40.5 °C (105 °F) in August 2013.

Global warming leads to much quicker spread of the Zika virus because the increased temperature, "makes mosquitoes mature faster, . . .
Flooding creates more standing water for mosquitoes to breed; as well, shown that these vectors are able to feed more and grow faster in warmer climates.

Ice mass loss is occuring at an accelerated rate in Greenland, Antarctica and globally from inland glaciers.
The Greenland, and possibly the Antarctic, ice sheets have been losing mass recently, because losses by ablation including outlet glaciers exceed accumulation of snowfall.

When the measuring equipment gets old and needs replacing, it often requires re-calibration.
Common in the oil and gas industry to replace old or damaged pipes on a like-for-like basis, the advantage of dimensional control survey is that the instrument used to conduct the survey does not need to be level.
