Our Planet has only until 2030 to stem catastrophic climate change, experts warn

Governments around the world must take “rapid, far-reaching and unprecedented changes in all aspects of society” to avoid disastrous levels of global warming, says a stark new report from the global scientific authority on climate change.

The report issued Monday by the UN Intergovernmental Panel on Climate Change (IPCC), says the planet will reach the crucial threshold of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels by as early as 2030, precipitating the risk of extreme drought, wildfires, floods and food shortages for hundreds of millions of people.

The date, which falls well within the lifetime of many people alive today, is based on current levels of greenhouse gas emissions.

The planet is already two-thirds of the way there, with global temperatures having warmed about 1 degree C. Avoiding going even higher will require significant action in the next few years.

“This is concerning because we know there are so many more problems if we exceed 1.5 degrees C global warming, including more heatwaves and hot summers, greater sea level rise, and, for many parts of the world, worse droughts and rainfall extremes,” Andrew King, a lecturer in climate science at the University of Melbourne, said in a statement.

Global net emissions of carbon dioxide would need to fall by 45% from 2010 levels by 2030 and reach “net zero” around 2050 in order to keep the warming around 1.5 degrees C.

Lowering emissions to this degree, while technically possible, would require widespread changes in energy, industry, buildings, transportation and cities, the report says.

“The window on keeping global warming below 1.5 degrees C is closing rapidly and the current emissions pledges made by signatories to the Paris Agreement do not add up to us achieving that goal,” added King.

Consequences of past inaction

The report makes it clear that climate change is already happening — and what comes next could be even worse, unless urgent international political action is taken.

“One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1 degree C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes,” said Panmao Zhai, co-chair of IPCC Working Group I.

Even if warming is kept at or just below 1.5 degrees C, the impacts will be widespread and significant.

Temperatures during summer heatwaves, such as those just experienced across Europe this summer, can be expected to increase by 3 degrees C says the report.

More frequent or intense droughts, such as the one that nearly ran the taps dry in Cape Town, South Africa, as well as more frequent extreme rainfall events such as hurricanes Harvey and Florence in the United States, are also pointed to as expectations as we reach the warming threshold.

Coral reefs will also be drastically effected, with between 70 and 90% expected to die off, including Australia’s Great Barrier Reef.

Countries in the southern hemisphere will be among the worse off, the report said, “projected to experience the largest impacts on economic growth due to climate change should global warming increase.”

The report underlines how even the smallest increase in the base target would worsen the impact of recent natural disasters.

“Every extra bit of warming matters, especially since warming of 1.5 degrees C or higher increases the risk associated with long-lasting or irreversible changes, such as the loss of some ecosystems,” said Hans-Otto Pörtner, Co-Chair of IPCC Working Group II.

The report cites specific examples of how impacts of global warming would be lessened with the 1.5 degrees C increase, compared to the 2 degrees C increase:

Global sea levels would rise 10 cm lower by 2100.

The likelihood of an Arctic Ocean free of sea ice in summer would be once per century, instead of at least once per decade.

Coral reefs would decline by 70% to 90% instead of being almost completely wiped out.

What can i do to help make a difference?

At the very least we should all be looking in to alternative sources to generate energy, such as solar panels and other renewable heating sources.

Unless drastic uptake of renewable happens immediately the consequences could be catastrophic for our planet.
