The WMO also suggests a 90 pct chance that at least one year between 2021 and 2025 will eclipse the current standings for the warmest year on record, currently measured in 2016.

The WMO release notes that although lock-downs due to the COVID-19 virus have led to improvements in air quality and cleaner skies in many places the effects are temporary and the pandemic will not have a long-term affect on climate change. The WMO also notes the long term and economic slowdown from COVID 19 is not a substitute for sustained and coordinated climate action to reduce greenhouse gas emissions.
"Unfortunately carbon dioxide concentrations measured at the Mauna Loa observing station in Hawaii reached a new record in May," the WMO noted. The most above-average temperatures were recorded over parts of Siberia where they were up to 10 degrees C above average. Records also were shattered in Alaska and Antarctica, according to the WMO release.

The increase in CO2 from 2017 to 2018 was close to that observed from 2016 to 2017 and just above the average over the last decade. Global levels of CO2 crossed the symbolic and significant 400 ppm benchmark in 2015.
Additionally, since 1990, there has been a 43 pct increase in total radiative forcing -- the warming effect on the climate -- by long-lived greenhouse gases. CO2 accounts for about 80 pct of this, according to figures from the US National Oceanic and Atmospheric Administration (NOAA) Annual Greenhouse Gas Index.

COP25 was originally scheduled for Brazil but moved to Chile after Brazil's right-wing President Jair Bolsonaro, widely criticized by environmentalists for his policies on the Amazon region, took office last January. However, following lengthy spells of civil unrest in Chile, the Sebastian Pinera government there announced in early November that the country was ceding the hosting of COP25 to Spain, four weeks before it was set to start.

In a report released Monday, the WMO said despite international pledges made under the Paris Climate Agreement (COP 15), the levels of carbon monoxide, methane and nitrous oxide all surged by higher amounts in 2018 than average for the past decade. The global average of carbon dioxide concentration reached 407.8 parts per million in 2018, up from 405.5 parts per million in 2017, the U.N. agency said. The concentration of methane was the highest recorded since 1998 while the levels of nitrous oxide, which is responsible for eroding the ozone layer was the highest ever recorded. The report was released ahead of next month's global climate summit in Madrid.
This follows the overwhelming scientific consensus delivered earlier this month that the Earth is indeed facing a climate emergency. Over 11,000 scientists world wide, including 409 from Canada, signed a letter pleading for world leaders to take the crisis seriously, for the wealthy to change their habits and for those in denial to accept that global warming is human driven.
Specific to Canada, Liberal Prime Minister Justin Trudeau has committed Canada to reaching net-zero emissions by 2050 and to reduce CO2 levels by 30 pct by 2030.
In December 2018, Climate Change Canada projected Canada's total emissions by 2030 are only on track to be 19 pct below 2005 levels.

The Copernicus Atmosphere Monitoring Service (CAMS), which has been tracking the fires, says the latitude and intensity of the fires, as well as the length of time they have been burning, have been particularly "unusual." According to CAMS "It is unusual to see fires of this scale at such high latitudes in June. But temperatures in the Arctic have been increasing at a much faster rate than the global average, and warmer conditions encourage fires to grow and persist once they have been ignited."
Since the beginning of June, CAMS has tracked more than 100 intense and long-lived wildfires in the Arctic Circle with the most severe in Alaska and Siberia, where some have been large enough to cover almost 100,000 football fields.
Copernicus, the EU's Earth Observation Programme, offers information services based on satellite Earth Observation and in situ (non-space) data.
The Programme is coordinated and managed by the European Commission (EC) and implemented in partnership with the EU Member States, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), EU Agencies and Mercator Ocean.

If fully supported by governments, the private sector and citizens, the Kigali Amendment will avoid up to 0.4 degrees C of global warming this century while continuing to protect the ozone layer. The amendment will substantively contribute to the goals of the COP15, Paris Climate Agreement.
The parties to the amendment have put in place practical arrangements for its implementation, including agreements on technologies for the destruction of HFCs and new data reporting requirements and tools. The amendment comes with provisions for capacity-building for developing countries, institutional strengthening and the development of national strategies to reduce HFCs and replace them with alternatives. Phasing down HFCs under the Kigali Amendment may also open a window to redesign refrigeration equipment that is more energy efficient, further increasing the climate gains.
Implementation of new targets set out in the amendment will be done in three phases, with a group of developed countries starting HFCs phase-down from 2019. Developing countries will follow with a freeze of HFCs consumption levels in 2024 and with a few countries freezing consumption in 2028.
Evidence presented in the latest Scientific Assessment of Ozone Depletion finds that the ozone layer in parts of the stratosphere has recovered at a rate of 1-3 pct per decade since 2000. At projected rates, Northern Hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s followed by the Southern Hemisphere in the 2050s and polar regions by 2060.
The UN Environment Ozone Secretariat is the Secretariat for the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer. The Secretariat facilitates and supports the parties to the Vienna Convention and the Montreal Protocol and other stakeholders in implementing actions to protect and heal the ozone layer and contribute to climate change mitigation.

According to the WMO Greenhouse Gas Bulletin there has been a 41 pct increase in the warming effect by the various greenhouse gases on the climate, known as "radioactive forcing", since 1990. CO2 specifically accounts for about 82 pct of the increase in radioactive forcing over the past decade, according to figures quoted in the WMO report. The new report adds yet another building block of scientific evidence to inform decision-making at the upcoming UN COP24 climate change conference in Poland. The key objective of this meeting is to adopt an implementation plan for the 2015 Paris Agreement.
In its 2017 Statement on the State of the Global Climate, WMO said
"We have witnessed extraordinary weather, including temperatures topping 50 degrees C in Asia, record-breaking hurricanes in rapid succession in the Caribbean and Atlantic reaching as far as Ireland, devastating monsoon flooding affecting many millions of people and a relentless drought in East Africa. This is part of a long-term warming trend." (Source: World Meteorological Organization, 28 Nov., 2018) Contact: WMO, Petteri Taalas, Secretary General, +41 (0) 22 73 0811, www.wmo.int

The increase in CO2 from 2016 to 2017 was smaller than from 2015 to 2016 and practically equal to the average growth rate over the last decade.
The influence of the El Nino event that peaked in 2015 and 2016 and contributed to the increased growth rate during that period sharply declined in 2017. For CH4, the increase from 2016 to 2017 was lower than that observed from 2015 to 2016 but practically equal to the average over the last decade. For N2O, the increase from 2016 to 2017 was higher than that observed from 2015 to 2016 and practically equal to the average growth rate over the past 10 years.
