There is substantial scientific evidence to support the conclusion that global temperatures are rising. Here are some key lines of evidence:
1. Temperature Records: Long-term temperature records collected from weather stations around the world consistently show an upward trend in global average temperatures over the past century. These records provide direct evidence of a warming climate.
2. Satellite Data: Satellites equipped with instruments that measure the Earth's temperature have been monitoring global temperatures since the late 1970s. Satellite data also indicates a warming trend, corroborating surface temperature measurements.
3. Ocean Heat Content: Measurements of ocean heat content reveal that the world's oceans are absorbing more heat, contributing to the overall increase in global temperatures. This data is collected from a network of buoys and other instruments.
4. Glacier Retreat: Glaciers around the world are melting at an accelerated pace. The retreat of glaciers is a clear indicator of rising temperatures, as they are highly sensitive to changes in climate.
5. Arctic Sea Ice Decline: Satellite observations and direct measurements show a significant reduction in Arctic sea ice extent and thickness over the past few decades. This decline is attributed to warming temperatures in the Arctic region.
6. Extreme Weather Events: There is a growing body of evidence linking the increase in frequency and intensity of extreme weather events, such as heatwaves, droughts, and heavy rainfall events, to rising global temperatures.
7. Climate Models: Complex computer models, known as climate models, simulate Earth's climate system and help scientists understand how it responds to different factors. These models have been successful in reproducing observed temperature changes when factors such as greenhouse gas emissions are taken into account.
It is important to note that while individual weather events cannot be attributed solely to global warming, the overall trend and convergence of multiple lines of evidence strongly support the conclusion that global temperatures are rising due to human activities, primarily the release of greenhouse gases into the atmosphere.

Step-by-step explanation:
there are lot of evidences to show there is rise in global temperatures few of them are
Temperature records. The global temperature is recorded annually. These show the increase of temperature if there is, over the past century.
Melting of arctic and the Antarctic. If the global temperature rises, the more the glaciers and ice retreats/melts.
