"Greenhouse gas emissions are at an all-time high, with yearly emissions
equivalent to 54 billion tonnes of carbon dioxide. Humanity has caused surface
temperatures to warm by 1.14°C since the late 1800s – and this warming is
increasing at an unprecedented rate of over 0.2°C per decade. The highest
temperatures recorded over land (what climate scientists refer to as maximum
land surface temperatures) are increasing twice as fast. And it’s these
temperatures that are most relevant to the record heat people feel or whether
wildfires spawn.
These changes mean that the remaining carbon budget for 1.5°C – the amount of
carbon dioxide global society can still emit and keep a 50% chance of holding
temperature rise to 1.5°C – is now only around 250 billion tonnes. At current
emission levels, this will run out in less than six years.
These are the findings of a new report that I have published with 49 other
scientists from around the world. It tracks the most recent changes in
emissions, temperatures and energy flows in the Earth system. Data that can
inform climate action. For example, by informing how fast emissions need to
fall to meet international temperature goals. The first report, in what is to
become a series of annual reports, has captured the pace at which Earth is
heating up.
We are launching an initiative called Indicators of Global Climate Change which
brings all the necessary ingredients together to track human-induced warming
year by year for the first time. We track emissions of both greenhouse gases
and particulate pollution and their warming or cooling influences to determine
their role in causing surface temperature change.
We use rigorous methods based on those established in the comprehensive United
Nations Intergovernmental Panel on Climate Change (IPCC) assessments. IPCC
assessments are trusted as a reliable source of information by governments and
their climate policy negotiators. Yet, they are published around eight years
apart.
In a rapidly changing world where policies can shift quickly, this leaves an
information gap: trusted indicators on the state of the climate have been
missing from annual UN climate negotiations."
