Meeting the Paris Agreement and keeping global warming below 2 ° C or 1.5 ° C will continue to raise sea levels and exacerbate land and sea heat waves. In Australia, we have seen our own share of recent extreme events intensified by climate change, such as record hot summers and the devastating wildfires of 20. Similarly, the extreme rainfall that led to the recent floods in Central Europe that hit the town in July was very likely. The heat wave in western North America in late June this year saw a surge in temperature records and heat-related deaths.This event is Virtually impossible Artificial greenhouse gas emissions do not warm the earth. To date, the world has warmed by about 1.2 ° C from pre-industrial levels and has already experienced the effects and deterioration of severe climate change. Sustainable year-over-year reductions in carbon emissions are needed to avoid the worst climate change effects. The report states that as regulations are relaxed, emissions are expected to rise sharply this year to slightly lower levels than in 2019.
Eleven of these targets are stipulated by law and account for 12% of global emissions.ĭid COVID-19 make a difference?Although carbon emissions have decreased 5-6% in 2020This was not a long-term change in the functioning of society, but a widespread blockade and other restrictions around the world. When the UNEP report was made, 49 countries and the EU had promised a net-zero target, which accounts for one-third of the world’s population and half of the world’s emissions. UNEP findings Briefing note Even if global emissions reach net zero by the middle of the century on Monday, Australian climate scientists say temperatures could exceed 2 degrees Celsius this century if they neglect to increase short-term action. These Net Zero targets, including Australia, are also based on technologies that do not yet exist on a large scale, such as carbon capture and storage.
UNEP can also mitigate expected temperature rises by effectively achieving the Net Zero target by the middle of the century, while current plans are ambiguous and many actions are delayed until after 2030. It turns out that by 2030, we need to reduce 28 million tonnes of carbon dioxide from our annual emissions, beyond what has already been promised. However, UNEP’s report shows that all these pledges are inadequate. Similarly, the European Union will reduce carbon emissions by at least 55% by 2030 compared to 1990 levels. As of August 30 (UNEP Report Review Date), 120 countries have made new or renewed pledges and announcements to reduce emissions.įor example, the United States has set an ambitious new goal in 2030 to reduce emissions by 50-52% from 2005 levels.
