With clear benefits to people and natural ecosystems, limiting global warming to 1.5°C compared to 2°C could go hand in hand with ensuring a more sustainable and equitable society. Read on to find out more…
Background of the Intergovernmental Panel on Climate
Change (IPCC) and their new report
Ninety-one authors and review editors from 40 countries prepared
the IPCC report in response to an invitation from the United
Nations Framework Convention on Climate Change (UNFCCC) when it
adopted the Paris Agreement in 2015. The IPCC is the leading world
body for assessing the science related to climate change, its
impacts and potential future risks, and possible response

of 1.5 °C; an IPCC special report on the impacts of global warming
of 1.5 °C above pre-industrial levels and related global greenhouse
gas emission pathways, in the context of strengthening the global
response to the threat of climate change, sustainable development,
and efforts to eradicate poverty
What are the main headlines of the report?
- Human activities are estimated to have caused approximately
1.0°C of global warming above pre-industrial levels, with a likely
range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C
between 2030 and 2052 if it continues to increase at the current
- Warming greater than the global annual average is being
experienced in many land regions and seasons, including two to
three times higher in the Arctic. Warming is generally higher over
land than over the ocean.
- Trends in intensity and frequency of some climate and weather
extremes have been detected over time spans during which about
0.5°C of global warming. This assessment is based on several lines
of evidence, including attribution studies for changes in extremes
- Limiting global warming to 1.5°C would require "rapid and
far-reaching" transitions in land, energy, industry, buildings,
transport, and cities. Global net human-caused emissions of carbon
dioxide (CO2) would need to fall by about 45 percent from 2010
levels by 2030, reaching 'net zero' around 2050. This means that
any remaining emissions would need to be balanced by removing CO2
from the air.
- With clear benefits to people and natural ecosystems, limiting
global warming to 1.5ºC compared to 2ºC could go hand in hand with
ensuring a more sustainable and equitable society
Is it too late? In short, not quite…
"The good news is that some of the kinds of actions that would
be needed to limit global warming to 1.5ºC are already underway
around the world, but they would need to accelerate," said
Valerie Masson-Delmotte, Co-Chair of IPCC Working Group I.
"The decisions we make today are critical in ensuring a safe
and sustainable world for everyone, both now and in the
future," said Debra Roberts, Co-Chair of IPCC Working Group
II, "This report gives policymakers and practitioners the
information they need to make decisions that tackle climate change
while considering local context and people's needs. The next few
years are probably the most important in our history."

global warming and how people can take action to reduce climate

The third sector has huge potential to tackle both the causes and
consequences of climate change. It is uniquely placed to reach and
support people, especially the most disadvantaged and vulnerable.

you understand what climate change is about, where to find support
to help you manage your climate risks, and how to make better
decisions for a changing future.
