"Avoiding dangerous climate change" (or "preventing dangerous anthropogenic interference with the climate system") is both a major, explicit policy of many national governments regarding global infrastructure development, harmonized with climate action, and a major objective and focus of current, related scientific research.
In 2002, the United Nations Framework Convention on Climate Change (UNFCCC), an international organization established by treaty in 1992, incorporated the objective as the focus of its formal Framework Convention policy.
Avoiding dangerous climate change and its equivalent terms have continued in common usage in the policy community, scientific literature. and news media. The problem that arises is to decide what level of interference would lead to "dangerous" change. The relevance of the issue is increasing as existing Earth System Models project that as early as 2020 in tropical areas, 2047 on average globally, the Earth's surface temperature could move beyond historical analogs, potentially impacting over 3 billion people and the most diverse places on Earth.
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as "global warming".
Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record—extending deep into the Earth's past—has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial and periglacial processes, stable-isotope and other analyses of sediment layers, and records of past sea levels. More recent data are provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.
Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.
Multiple lines of scientific evidence show that the climate system is warming. Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular press, most of the additional energy stored in the climate system since 1970 has gone into ocean warming. The remainder has melted ice and warmed the continents and atmosphere. Many of the observed changes since the 1950s are unprecedented over decades to millennia.
Scientific understanding of global warming is increasing. The Intergovernmental Panel on Climate Change (IPCC) reported in 2014 that scientists were more than 95% certain that global warming is mostly being caused by increasing concentrations of greenhouse gases (GHG) and other human (anthropogenic) activities.Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to 1.7°C (0.5 to 3.1°F) for their lowest emissions scenario using stringent mitigation and 2.6 to 4.8°C (4.7 to 8.6°F) for their highest. These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing.
Climate Change 2007, the Fourth Assessment Report (AR4) of the United NationsIntergovernmental Panel on Climate Change (IPCC), is the fourth in a series of reports intended to assess scientific, technical and socio-economic information concerning climate change, its potential effects, and options for adaptation and mitigation. The report is the largest and most detailed summary of the climate change situation ever undertaken, produced by thousands of authors, editors, and reviewers from dozens of countries, citing over 6,000 peer-reviewed scientific studies.
The headline findings of the report were: "warming of the climate system is unequivocal", and "most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations."

CLIMATE CHANGE : IS THE WORLD ON TRACK TO AVOID DANGEROUS CLIMATE CHANGE?
Lives and livelihoods around the world are being damaged by the increasing impacts of climate change. the opportunity to avoid dangerous warming of more than 1.5 Celsius degrees could disappear without a successful outcome to the COP27 United Nations climate change summit in Egypt in November 2022.

Why I don't care about 'Climate Change' | David Saddington | TEDxTeen
This talk was given at a local TEDx event, produced independently of the TED Conferences. You don't care about climate change right? Because it's a bunch words of things that don't affect your daily life. Think again. In this provocative talk, Saddington gives us a new lens on climate change. It's a game changer.
Influencing UK government policy, establishing his own social enterprise and fronting a media campaign that reached over 3 million people are just a few of David’s achievements as a climate change activist since being impacted by a stark reminder of climate change as a teenager.

From a meeting with then Prime Minister Tony Blair at 10 Downing Street, he discussed the implementation of climate change on the national curriculum. Climate change is now an essential part of youth education and he has pushed to expand these education reforms worldwide.
As a Three Dot Dash Global Teen Leader, he has expanded his philanthropic and award-winning social enterprise, which has developed eco gardens across Northern England and within the historic grounds of Durham University.
David has acted as an environmental consultant for countless organisations and is a regular commentator on contemporary climate issues within academic arenas and international media outlets. He has studied the science of climate change at Durham University for 3 years and led a groundbreaking glacier survey expedition to Vatnajökull, Iceland. His most recent venture transformed the medieval Market Square of Durham City into an outdoor cinema to showcase the award-winning documentary Chasing Ice. He then chaired ‘Climate Change Question Time,’ where the public could grill world leading climate experts on the science behind the headlines and how to tackle the problem.
David believes that we must act as a species rather than via fragmented interests in order to tackle this remarkable global disruptor.
