ADDING THE METRIC OF TIME TO THE GLOBAL WARMING CONVERSATION
Time is something we all understand.
We all now know that if the global average temperature passes the threshold of 1.5 to 2°C above pre-industrial averages, really bad things could start to happen … and it becomes much more difficult to slow down the effects of global warming. But when will we get there? And what do we need to do to change direction? The Climate Clock acts a public line in the sand and says, this is the date. It is a measuring stick by which we can evaluate our progress.
The Climate Clock is based on the best available science, and is updated each year to reflect the latest data by a group of leading climate scientists from around the world. Each year, we are able to show how we are doing in relation to 1.5 and 2°C. Have we gained time or lost time?
Humanity has the power to add time to the Clock, but only if we work collectively and measure our progress against defined targets.
The Clock represents a radical new way to measure climate change, by using a metric we understand. This relationship between temperature and time is crucial in the story of climate change but has been largely missing from the narrative.
“We have been given a very short window of opportunity by the Intergovernmental Panel on Climate Change (IPCC) — that’s why the Climate Clock is so important. The clock is ticking and we need to be reminded of how little time we have left to act.” David Suzuki
We don’t measure our lives in degrees. We measure our lives in years.
The Clock is built to scale. It can be downloaded and embedded on any website as an iframe. For outdoor building projections or at conferences, the Clock can be downloaded as a simple Google Chrome app and played on any computer running the latest version of Chrome (no internet connection is required as the Clock’s date and time is validated by the internal date and time of the computer). We can easily customize the Clock to any language but presently it runs in French and English. Please contact us of you would like to project the Climate Clock and we will send you the instructions for how to do so.

THE NUMBERS ON THE CLOCK:
The Climate Clock shows our best estimate of when global temperature will reach 1.5 and 2 °C above average pre-industrial temperatures, assuming global CO2 emissions continue to increase following the observed trend of the past five years.
All numbers are estimated relative to 1850-1900 as the reference temperature for the “pre-industrial” period. This is the earliest period for which we have reliable measurements of global temperature, and is the most common reference period for pre-industrial temperatures used in scientific analyses and policy discussions.
The Clock includes the following elements:
1) Tonnes of CO2 Emitted
This value shows the total accumulated CO2 emissions from fossil fuel burning, cement manufacture and land-use change since 1870, based on the most recent data from the Global Carbon Project.
2) Global Warming to Date
This number represents the human contribution to global temperature increases since 1861-1880. This Global Warming Index represents the portion of observed temperature change that can be attributed to all human drivers of climate change.
3) Time left to 1.5 and 2 °C
The time remaining until +1.5 and +2 °C date is estimated based on extrapolating the most recent 5-year trend of global annual fossil fuel CO2 emissions and calculating the time until we emit the remaining carbon budget – the total allowable emissions for 1.5 and 2°C. Fossil fuel emissions are currently increasing by about 0.1% (or 0.4 billion tonnes) per year and are expected to exceed 37 billion tonnes in 2018. We assume CO2 emissions from deforestation remain constant at current levels. We use best estimates of the remaining carbon budget from the IPCC Special Report on 1.5°C: 770 billion tonnes after 2017 for 1.5°C and 1690 billion tonnes for 2°C. These estimates the remaining carbon budget assume a 25% warming contribution from non-CO2 greenhouse gas and aerosol emissions.
