UN Warns of Destructive Effects Due to Global Temperature Rises

Global Temperature

International climate experts warned on Tuesday 25th that the global temperature could rise sharply this century with a wide-ranging and destructive consequence after greenhouse gas emission hit record levels last year.

‘Global temperatures could rise by 3-5 degrees Celsius above pre-industrial levels this century more than three times agreed limits if nothing is done to stop rising emissions.’ Said the head of the World Meteorological Organisation.

The United Nations stated in its ‘Emissions Gap Report’ that greenhouse gas emissions surged to record level last year. The report as released ahead of UN climate talks in Madrid next week aimed at spurring world leaders to limit climate change.

The report further indicated that It measures the amount of emissions cuts needed to limit global temperature rises to 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels, as agreed in the 2015 Paris Agreement. The U.N. Intergovernmental Panel on Climate Change last year warned of huge global changes if that target is not met, such as the loss of nearly all coral reefs and most Arctic sea ice.

A summary of the report said that under the current national pledges to cut emissions, ‘temperatures can be expected to rise by 3.2C this century, bringing wide-ranging and destructive climate impacts’

“With 3 degrees we would lose a fairly big fraction of the current (agricultural) yield and areas like Africa where the population is growing would really suffer,” said WMO Secretary-General Petteri Taalas

‘The safest temperature threshold set in Paris – of 1.5C – was still achievable, but would require emissions cuts of 7.6% a year between 2020-2030. Limiting the rise to 2C it would mean annual cuts of 2.7%’ said the UNEP report said.

The report showed that emissions, including those from land-use change such as deforestation, had not yet peaked and rose to a record 55.3 gigatonnes of carbon dioxide equivalent in 2018.

We are talking about transformational change now – incremental change simply will not make it. We simply need to transform societies in the next 10 years,” the report’s lead author John Christensen said. Christensen urged countries that had met their targets comfortably, such as Turkey and Russia, to tighten them significantly.

The report named the United States as one of several large emitters, alongside Brazil and Japan, falling short of its own targets, or Nationally Determined Contributions (NDCs). This month, the Trump administration filed paperwork to quit the Paris Agreement in the first step of a formal withdrawal process.

Some officials have downplayed the impact of the U.S. move, saying that companies, as well as states and cities, have boosted commitments to fight climate change.

Still, UNEP’s executive-director Inger Andersen urged Washington to reconsider. “So, the bottom line here is, stick, stay at the table, negotiate, engage and ensure that we, together, can move forward on climate action.”

Countries face a 2020 deadline to set more ambitious emissions cut pledges. “Had we done it 10 years ago, it would have been easier,” said Andersen.
