Climate Change Facts & Statistics

Welcome to the Carbon Dash climate change and carbon emissions fact centre. This is our humble attempt to compile all the known facts about climate change, with links to the most credible sources that verify the fact, and in some cases, supporting information such as infographics or charts. 

There is a huge amount of information and misinformation about the climate, and climate change (some people even believe the earth is flat). So in all cases we have attempted to present opposing views, if there are any.

Global temperatures have risen ~1.3 degrees celsius since pre-industrial levels

Temperatures around the world have risen, on average, 1.1 degrees celsius since the 1860's - the time that is generally agreed when industrialisation began. This data is courtesy of NASA, and has been corroborated by the World Meteorological Association.

Antarctica is losing 147 billion tons of ice each year

Antarctica is huge - 13.66 million square kilometre of terrain including all its islands and ice shelves. However, according to satellite data and observational data from many of the 43 permanent active research stations situated in Antarctica, it is losing 147 billion tons of ice mass each year, on average.

An overwhelming number (up to 99.9%) of scientists agree that human activity is causing climate change

The widely reported fact that 97% of scientists agree that climate change is apparently not true - if an article from 2016 Forbes is to be believed. That article states the number is closer to 84%, according to cited studies. However a more recent study in 2021, reported that more than 99.9% of peer-reviewed scientific papers agree that climate change is mainly caused by humans. This was according to a study of a whopping 88,125 climate-related studies. So we will just state the number as 'overwhelming'.

At 2 degrees celsius global warming, 99% of coral reefs will die. We are almost at 1.5 degrees warming

Can you imagine a world without coral reefs? There are many, many fish in our oceans that cannot. It is horrible to think that humans might cause the destruction of coral reefs around the world. Sadly, this seems to be the case. The Intergovernmental Panel on Climate Change reported that around 99% of coral reefs will die out if the world warms by 2 degrees. This is why the Paris Agreement binded more than 55 countries to a goal of only 1.5 degrees in global warming in 2016.

2 degrees is just average - it will be much hotter in some places including the Arctic, and Southwest USA, where near-permanent super-droughts will occur

The fossil fuel industry in China emitted over 11.47 billion tonnes of greenhouse gases into the atmosphere and the oceans in 2021, more than double that of the second placed country, USA. Pleasingly though, the USA has actually reduced emissions steadily since 2006. China nearly doubled their emissions in that time.

Globally, it is estimated that $500 billion in government subsidies flows into the oil, coal and gas industries

With such a huge, coordinated global effort to reduce global warming, you might be surprised governments globally hand out more than $500 billion USD of taxpayer money to the coal, oil and gas industries. One of the best ways they can solve the climate crisis is to simply stop these handouts

65% of employees would prefer to work for a company with a robust environmental policy

It is without a doubt that most regular people (consumers, as businesses like to call us) would like to more being done to prevent extreme weather events and other harmful aspects of climate change. This is now shown manifesting in the workplace and employees are voting with their feet, showing a real preference to work for companies that are serious about the environment

China is the world's largest polluter. USA is the second largest

The fossil fuel industry in China emitted over 11.47 billion tonnes of greenhouse gases into the atmosphere and the oceans in 2021, more than double that of the second placed country, USA. Pleasingly though, the USA has actually reduced emissions steadily since 2006. China nearly doubled their emissions in that time.

One hectare of trees remove up to 41 tons of CO2 each year

Trees naturally capture carbon dioxide and breathe out oxygen. It is how they are built. And now we know exactly how much, thanks to a detailed study from One Tree Planted.

One hectare of mangroves removes 23 tonnes of CO2 from the atmosphere... but they might die out by 2050

Mangrove are an incredibly efficient storage 'device' for carbon dioxide, but they are under threat from sea level rise. As sea levels rise, they are exposed to more salt water which compromises their ecosystem. Even a minor sea level rise might cause mangroves to disappear by 2050

The fossil fuel industry alone is emitting 37 trillion tonnes of carbon dioxide each year

Almost 37 trillion tonnes of greenhouse gases (primarily carbon dioxide) were released into the atmosphere and the oceans in 2022. These CO2 emissions came from energy combustion and industrial processes.

We are 'over spending' our carbon budget - Humans are emitting 2.5X more greenhouse gases than what was 'budgeted'

Trees naturally capture carbon dioxide and breathe out oxygen. It is how they are built. And now we know exactly how much, thanks to a detailed study from One Tree Planted.

There is more carbon dioxide and methane in the atmosphere right now than at any time in the past 800,000 years

As at September 2023, carbon dioxide is currently at 410 parts per million in the atmosphere. Methane is at 1,866 parts per million.

The production of concrete is responsible for 4-8% of global greenhouse gas emissions

We need to build things, and concrete is a sturdy material, but we need greener sturdy materials than concrete
