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 Nations Intergovernmental 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.
It supersedes the Third Assessment Report (2001), and is superseded by the Fifth Assessment Report.
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."
The report was released in four principal sections:

Our home is burning. Rapid climate change is destabilizing our world. It seems our emissions will not fall quickly enough to avoid runaway warming and we may soon hit tipping points that will lead to the collapse of ecosystems and our civilization. While scientists, activists and much of the younger generation urge action, it appears most politicians are not committed to do anything meaningful while the fossil fuel industry still works actively against change. It seems humanity can’t overcome its greed and obsession with short term profit and personal ...

RCP 8.5 has often been referred to as “business as usual.” It describes a world without action on climate policy and continued fossil fuel use expanding unchecked, leading to a truly apocalyptic future for our climate and everything living on our planet – including us. For this episode we wanted to see where we are in terms of “business as usual,” and if we are still headed towards an apocalypse of sorts… or if, perhaps, all of the technological innovations in renewables and EVs along with new climate policy such as the Paris Agreement might have bent down the curve on global warming.

I'm not sure that I will be very well-suited
To the new post-climate change society
It bothers me
I'm not sure that I have the tools to deal
With the complete collapse of the modern world
I'd be rooted
I burn easily
And my feet get sore when I walk barefoot
It's pathetic
I'd last two seconds
I'm not sure that I'd have a chance in a half-drowned,
post-technological world
I'm not sure that I know enough about bush tucker
Or how to get water from cactuses
Aren't they prickly or something
I've got no Indigenous friends
And I'm sure they'd get sussed
If I tried to buddy up to them at this late stage
They'd be onto me
I get bored quickly
If I couldn't stare at a screen all day
I'd have no purpose
I'd be a vegetable
I'm not sure that I'd have a chance in a DIY, make-
your-own-fun world
Even allowing for the possibility
That it might not be exactly like Mad Max
You can be sure that there'd still be a healthy amount
Of fighting marauders off
And I'm not much good
At fighting marauders off
I learnt this at my year twelve formal
I'm not sure that I have the upper body strength
To cope with all the rowing in an ocean-based world
I'd be completely at sea
And my word-smithery would fall on deaf ears
With the people with hats made of sheep skulls
Then they'd kill me
I'm not sure that there'd be a place for a fey, bookish
technophile
In a physically challenging, nomadic, foraging,
