If all 2030 climate targets are met, the planet will heat by 2.7 C this century

If nations make good on their latest promises to reduce emissions by 2030, the planet will warm by at least 2.7℃ this century, a report by the United Nations Environment Programme (UNEP) has found. This overshoots the crucial internationally agreed temperature rise of 1.5℃.

Released today, just days before the international climate change summit in Glasgow begins, UNEP’s Emissions Gap Report works out the difference between where  are projected to be in 2030 and where they should be to avoid the worst climate change impacts.

It comes as the Morrison government yesterday officially committed to a target of net-zero emissions by 2050. The government made no changes to its paltry 2030 target to reduce emissions by between 26% and 28% below 2005 levels, but announced that Australia is set to beat this, and reduce emissions by up to 35%.

The UNEP report was conducted before Australia’s new 2050 target was announced, but even with this new pledge, global pledges will undoubtedly still be short of what’s needed.

The report found global targets for net-zero emissions by mid-century could cut another 0.5℃ off . While this is a big improvement, it will still see temperatures rise to 2.2℃ this century. If we don’t close the global emissions gap, what will Australia, and the rest of world, be forced to endure?

Pledges are falling short

As of August 30 (the date the UNEP report reviewed to), 120 countries had made new or updated pledges and announcements to cut emissions.

The US, for example, has set an ambitious new target of reducing emissions by 50–52% below 2005 levels in 2030. Similarly, the European Union will cut carbon emissions by at least 55% by 2030, compared with 1990 levels.

This is the most sobering report card yet on climate change and Earth’s future. Here’s what you need to know

This is the most sobering report card yet on climate change and Earth’s future. Here’s what you need to know

Earth has warmed 1.09℃ since pre-industrial times and many changes such as sea-level rise and glacier melt are now virtually irreversible, according to the most sobering report yet by the Intergovernmental Panel on Climate Change (IPCC).

The report also found escape from human-caused climate change is no longer possible. Climate change is now affecting every continent, region and ocean on Earth, and every facet of the weather.

The long-awaited report is the sixth assessment of its kind since the panel was formed in 1988. It will give world leaders the most timely, accurate information about climate change ahead of a crucial international summit in Glasgow, Scotland in November.

The IPCC is the peak climate science body of the United Nations and the World Meteorological Organization. It is the global authority on the state of Earth’s climate and how human activities affect it. We are authors of the latest IPCC report and have drawn from the work of thousands of scientists from around the world to produce this new assessment.

Sadly, there is hardly any good news in the 3,900 pages of text released today. But there is still time to avert the worst damage, if humanity chooses to.

It’s unequivocal: humans are warming the planet

For the first time, the IPCC states unequivocally — leaving absolutely no room for doubt – humans are responsible for the observed warming of the atmosphere, lands and oceans.

The IPCC finds Earth’s global surface temperature warmed 1.09℃ between 1850-1900 and the last decade. This is 0.29℃ warmer than in the previous IPCC report in 2013. (It should be noted that 0.1℃ of the increase is due to data improvements.)
