The world has seen an average six percent drop in greenhouse gases during the corona virus pandemic due to industry shutdowns and shutdowns.
Although levels rose to new records last year, the drop is still not significant enough to halt climate change, the United Nations Weather Agency warns.
Experts say that once the global economy begins to recover, emissions will return to normal and continue to contribute to climate change.
They also anticipate an increase in emissions, as many industries shut down production completely during the outbreak.

The coronavirus started in Wuhan, China in December 2019 and has since spread to almost every country in the world.
As of Thursday, there have been more than 2.5 million cases and the death toll is 174,000.
Since the outbreak, many countries have implemented home orders and the shutdown of numerous companies.
The decline in human activity has led to a decline in carbon dioxide levels around the world, including major gas manufacturers such as India, parts of Europe and China.
But Professor Petteri Taalas, secretary general of the World Meteorological Organization (WMO), said, “Unfortunately, this drop in emissions by six percent is (only) good news in the short term.”
“There may even be an increase in emissions because some industries have stopped.”

WMO recently released data to coincide with Earth Day’s 50th anniversary held Wednesday.
The data shows that the carbon dioxide content from 2015 to 2019 was 18 percent higher than the previous five years.
The report notes that greenhouse gases remain in the atmosphere and oceans for centuries. This means that the world is committed to continued climate change, regardless of any temporary reduction in emissions from the Coronavirus epidemic. ‘
The expected drop in carbon emissions is reflected in a drop in the level of common air pollutants from car exhaust and fossil fuels, such as nitrous oxide (N2O) particles.
“Their lifespan is usually from days to weeks, so the impact is seen more quickly,” Taalas said. “But these changes in CO2 emissions have so far had no impact on the climate.”
He also noted that air quality in industrial cities improved dramatically.
‘In China, in India and here in the Po Valley in northern Italy, one of the most polluted areas in Europe. And we have also seen that in individual cities such as Paris. ‘

The WMO Secretary General stressed that unless the world can mitigate climate change, it will lead to ‘persistent health problems, in particular hunger and the inability to feed the growing world population, as well as a greater impact on the economy’ .
Since Earth’s first day in 1970, carbon dioxide levels have risen by 26 percent and the world’s average temperature has risen by 33.5 degrees Fahrenheit.
The planet is also nearly 34 degrees warmer than the pre-industrial era – a trend that’s expected to continue.
In its latest report, warning about the effects of climate change, the UN agency confirmed that the past five years had been the hottest ever recorded.
However, global warming was uneven around the world.
Europe experienced the hottest temperatures of the past 10 years, which were about 32.9 degrees higher than average, but South America saw the least change.
There are other important indicators that have accelerated climate change in the past five years.
These include ocean heat and acidification, rising sea-level glacial melt, and sea ice shedding in the Arctic and Antarctic (with ice loss five times higher in the past five years compared to the 1970s).
