Climate warning

New ”normal” reference period for meteorogists hide climate change for the public

World meteorological organization, WMO, recommends that meteorologist institutes all over the world change reference period for Climatological Normals every 30 years. As a consequence we have a new ”normal” from January 1st 2021 and that is the period 1 January 1991 to 31 December 2020 instead of the previous ”normal” that was 1 January 1981 to 31 December 2010. In Sweden this has already lead to weather reports on TV where temperatures are communicated being normal for season that would not have been normal if compared to the previous normal period. Without being communicated by SMHI, the Swedish Meteorological and Hydrological Institute. We know that the climate is significantly more affected by global warming after 1990. This is very misleading and dangerous in a time when we all have to rise our climate awareness and face the climate emergency. I strongly suggest you to reconcider what period in time that shoud be used as normal when communicating weather and climate to the public and then communicate this to your community all over the world as soon as possible. https://www.wmo.int/pages/prog/wcp/wcdmp/GCDS_1.php See also https://app.wedonthavetime.org/posts/b2c87dbc-d985-4678-93a8-63e175c9b839?fbclid=IwAR1dtbBVFyN2oGCuFDISLG6jbb7kr8fFOS84DY8G2k0EkBI3vvX8Uc6slDQ

    It is very difficult to understand that climate is changing so quickly when this ”New” way of adressing figures is used. I feel close to desperation ...who Will tell the truth? The warmth is a danger...and We can still slow it down...if We know and understand...what the meterologists say.

      Ps. This new "normal period" is better when meteorologists are doing weather forecasts/predictions I assume (excuse my english) but should not be used when temperatures etc are compared to what is normal for a specific month etc in the weather reports to the public.

            Why is WMO doing It, whose agenda are they pushing on us?

              I think it's a classic case of "We have done this for a long time so we shouldn't change it". Large organisations like this need to take responsibility and make the necessary changes.

                It was decided in 1930 but the circumstances has changed since then and so should the recommendation, I belive. SMHI claim this is benificial for community planning and that climatologists will use other reference periods. But why should this new "normal" be used in weather reports to the general public? It is madness!

                We've been asking, begging and nearly enough threatening the SMHI to expain to its viewers in a tutorial way how the climate crisis affects the weather. And what do we get? A manual to be abused and used by the deniers. It's like giving a didactor a new tool to achieve his evil purposes!

                  This is so important for most people's understanding of what is "normal" weather. A lot of people still don't understand why the weather we have nowadays is so extraordinary, because it's easy to forget how it used to be. WMO should help meteorologists be more clear about the abnormality of weather patterns today!
