Weather is the conditions in the air above the earth such as wind, rain, or temperature, especially at a particular time over a particular area.

Climate is the general weather condition found in a particular place.

Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time.

Scientists have observed Earth’s surface is warming, and many of the warmest years on record have happened in the past 20 years.

Temperatures have risen during the last 30 years, and 2001 to 2010 was the warmest decade ever recorded.

As the Earth warms up, heat waves are becoming more common in some places.

Higher temperatures mean that heat waves are likely to happen more often and last longer, too.

Heat waves can be dangerous, causing illnesses such as heat cramps and heat stroke, or even death.

Warmer temperatures can also lead to a chain reaction of other changes around the world. That's because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals.

The warmer it gets, the more severe the impacts on people and the environment will be. For climate change, UN has revealed 8 target plans that they aim to achieve from 2020 to 2030.

The eight targets include reduction of carbon emissions, electricity consumption, commercial air travel and increase of renewable energy, climate neutrality, operational efficiencies, sustainable development and events.

The Paris Agreement is the first-ever universal, legally binding global climate change agreement, adopted at the Paris climate conference (COP21) in December 2015.

The Paris Agreement sets out a global framework to avoid dangerous climate change by limiting global warming to well below 2°C and pursuing efforts to limit it to 1.5°C.
