It-Tibdil fil-Klima: wara t-twissja ta’ Covid-19

 

Il-virus Covid-19 beżbiżna waħda sew u ħarbat il-ħidma ta’ kulħadd. Imma ħdejn l-impatti antiċipati tat-tibdil tal-klima dan hu kollu logħob tat-tfal li dwaru Covid-19 jista’ jitqies bħala prova parzjali. Twissija li forsi tiftħilna ftit għajnejna.

F’Pariġi fis-7.25pm ta’ nhar it-12 ta’ Diċembru 2015, 5,000 delegat li kienu qed jirrappreżentaw 195 pajjiż, unanimament aċċettaw l-evidenza dwar l-impatti tal-klima. Huma għażlu t-triq għall-futur.

Nhar il-25 ta’ Frar 2020 Christiana Figueres u Tom Rivette-Carnac ippreżentawna b’publikazzjoni li għandha tkun ta’ interess kbir. Hi intitolata “The Future We Choose. Surviving the Climate Crisis.” Christiana Figueres, li magħha hu assoċjat il-ftehim ta’ Pariġi, kienet tmexxi l-Aġenzija tal-Ġnus Magħquda inkarigata mit-Tibdil fil-Klima (UNFCC) bħala Segretarju Eżekuttiv. Tom Rivette-Carnac kien l-istrateġista ewlieni tagħha inkarigat biex jaħdem dwar l-appoġġ minn utenti (mhux Gvernijiet) li kienu nteressati f’dan il-ftehim li kien ilu jinħema s-snin.

Wara l-qbil dwar it-triq li setgħet twassal għal bidla, biex il-kliem miktub ikun trasformat f’azzjoni konkreta hu dejjem sfida. L-għażliet quddiemna huma ċari.

L-attitudni li qiesu mhu jiġri xejn (business as usual) twassal biex it-temperatura medja globali, li diġa qabżet bi grad wieħed Celsius it-temperatura medja ta’ qabel żmien ir-rivoluzzjoni industrijali, tista’ tiżdied b’madwar 4 sa 5 gradi Celsius. L-impatti ta’ żieda bħal din ikunu katastrofiċi. Riżultat ta’ żieda fit-temperatura globali f’xi reġjuni jkun impossibli li persuna toqgħod barra fl-apert għal ħin twil. Ħtija ta’ hekk partijiet mid-dinja isiru mhux abitabbli. Iż-żieda fit-temperatura tkompli taċċellera id-dewbien tas-silġ fil-poli u ħtija t’hekk il-livell tal-ibħra jibqa’ jiżdied. Il-komunitajiet mal-kosta jkunu taħt theddida kontinwa. L-impatti fuq l-infrastruttura kostali kifukoll fuq kull attività mal-kosta jkunu sostanzjali.

It-tibdil fil-kundizzjonijiet atmosferiċi jżidu x-xita intensiva f’żoni u nixfa tqarqaċ f’żoni oħra. Il-maltemp iżid kemm fil-frekwenza kif ukoll fl-intensità u l-ħerba assoċjata miegħu tikber bil-bosta kif naraw spiss diġa f’diversi partijiet tad-dinja.

Il-konklużjonijiet ta’ Pariġi jfissru li l-komunità internazzjonali għarfet u àccettat l-evidenza xjentifika akkumulata dwar it-tibdil fil-klima. F’Pariġi kien hemm qbil li kull pajjiż kellu jidentifika sensiela ta’ wegħdiet li kellu jwettaq fl-isforz globali biex tkun indirizzata l-kawża tat-tibdil fil-klima. Wegħdiet li għandhom ikunu aġġornati kull ħames snin. Il-wegħdiet reġistrati s’issa, anke kieku kellhom jitwettqu kollha, m’humiex biżżejjed biex iż-żieda fit-temperatura globali ma taqbiżx iż-żewġ gradi Celsius, u preferibilment mhux iktar minn grad u nofs Celsius, kif insistew il-komunitajiet ta’ mal-kosta kif ukoll il-gżejjer li mhumiex wisq il-fuq mil-livell tal-baħar. Bejn il-kliem u l-fatti, hemm baħar jikkumbatti.

Sal-2030 l-emissjonijiet globali jeħtieġ li jonqsu b’mhux inqas min-nofs biex jintlaħqu l-miri stabiliti f’Pariġi. Sal-2050, min-naħa l-oħra jrid jintlaħaq l-istatus ta’ karbonju żero. Biex jintlaħqu dawn il-miri essenzjali Christiana Figueres u Tom Rivett-Carnac jagħmlu użu minn diversi proposti li saru tul is-snin. Il-bidla meħtieġa hi waħda enormi: hi bidla li tant hi kbira li taqleb ta’ taħt fuq kważi kull ħaġa li jmmissu jdejna.

Tirrikjedi bidliet radikali dwar kif ngħixu, kif naħdmu u kif niċċaqalqu minn post għall-ieħor. Tibdil f’dak li nikkunsmaw kif ukoll kemm dwar dak li nipproduċu kif ukoll dwar il-mod kif nipproduċuħ.

Il-wasla fuqna għall-għarrieda tal-kriżi Covid-19 tatna togħma żgħira ta’ xi tibdil essenzjali. Ix-xogħol b’mod virtwali għandu, bla dubju, jkun element permanenti dwar il-mod kif naħdmu. M’għandux ikun eċċezzjoni ta’ natura temporanja. L-edukazzjoni ukoll għandha tingrana iktar fid-direzzjoni tat-tagħlim virtwali b’mod permanenti.

L-ivvjaġġar mhux essenzjali għandu jkun skoraġġit fuq bażi permanenti. Fejn meħtieġ l-ivvjaġġar għandu jsir b’mezzi sostenibbli. Dan m’għandux ikun limitat għall-elettrifikazzjoni tal-karozzi, wara li jkunu tnaqqsu drastikament fin-numru, imma għandu jinkludi tnaqqis sostanzjali tal-ajruplani. Għax l-azzjoni dwar it-tibdil fil-klima jfisser li l-ivvjaġġar bl-ajru (inkluż it-turiżmu) kif nafuh sal-lum m’għandux futur. L-ivvjaġġar bl-ajru jiġi jiswa’ ferm iktar mil-lum kemm-il darba l-impatti ambjentali sostanzjali tiegħu ikunu riflessi fl-ispejjes reali.

Jekk inħarsu fit-tul l-iżvilupp intensiv tal-infrastruttura tat-toroq mhi ser isservi l-ebda skop. Inqas karozzi fit-toroq ikun ifisser ukoll impatti konsiderevoli fuq l-ippjanar għall-użu tal-art. Inqas karozzi jfisser inqas ħtieġa għal parkeġġ u garaxxijiet u iktar spazju għan-nies. Ikun wasal iż-żmien li fl-ibliet u l-irħula tagħna r-reżidenti jiġu mill-ġdid qabel il-karozzi. Dejjem, mhux kultant.

Jeħtieġ li napprezzaw u nagħmlu użu iktar minn prodotti agrikoli lokali. Imma anke l-prezz tal-prodotti agrikoli għandhom jirriflettu l-impatti ambjentali sostanzjali li jinħolqu biex il-biedja tagħti r-riżultati. L-ispiża tal-produzzjoni tal-laħam u tal-prodotti derivati mill-ħalib, per eżempju, ma tkunx waħda żgħira jekk din tinkludi l-impatti ambjentali tal-produzzjoni. Fil-fatt, Christiana u Tom, jistqarru li l-ikel fl-2050 hu għali minħabba li jeħtieġ riżorsi ta’ valur biex il-produzzjoni tiegħu tkun possibli. “L-ilma. Il-ħamrija. L-għaraq. Il-ħin.” Hu ċar li jekk irridu nimplimentaw bis-serjetà l-ftehim ta’ Pariġi l-Politika Komuni kurrenti dwar l-Agrikultura m’għandhiex futur.

L-impatti tal-Covid-19 huma logħob tat-tfal meta wieħed jara sewwa x’hemm lest għalina bħala riżultat tat-tibdil fil-klima. Fid-dawl tat-tibdil fil-klima hemm soluzzjoni prattika waħda: bidla radikali fil-mod kif ngħixu, naħdmu u nqattgħu l-ħin liberu. Permezz tal-Covid-19 in-natura tatna twissija ċara. Jekk dan ninjorawh m’hemm ħadd f’min nistgħu nwaħħlu.

Climate Change: after the Covid-19 rehearsal

Covid-19 virus has rattled each one of us, throwing all into unprecedented turmoil. This is however child’s play when contrasted with the anticipated impacts of climate change in respect of which Covid-19 may be considered as a rehearsal or a minor drill!

In Paris, at 7.25pm on 12 December 2015, five thousand delegates representing 195 nations unanimously accepted irrefutable evidence on the impacts of climate change and selected a pathway for the future.

On 25 February 2020 Christiana Figueres and Tom Rivette-Carnac presented us with a riveting publication entitled “The Future We Choose. Surviving the Climate Crisis.” Christiana Figueres, public face of the Paris agreement, was the Executive Secretary of the United Nations Framework for Climate Change (UNFCC). Tom Rivette-Carnac was her Chief Political Strategist. He joined the effort to advance the Paris Agreement negotiations, mobilising support from a wide range of stakeholders outside national governments.

After selecting the pathway which could lead to change, transforming words into action can be quite a challenge. The options we face are unequivocal.

Business as usual would signify that the current mean global temperature, which is already around 1 degree Celsius above average temperatures before the industrial revolution, can warm up by 4 to 5 degrees Celsius. The impacts of such an increase in global temperature would be catastrophic.

Increasingly, in some regions, as a result of an increase in global temperature it would be impossible to stay outdoors for a length of time. Parts of the earth will, as a result, become uninhabitable. The increased temperatures at the poles will accelerate the melting of the polar ice-caps, as a result further increasing the rise in sea-level. Coastal communities will be under threat and all coastal activity and infrastructure will be severely impacted.

The change in atmospheric conditions will increase precipitation in areas and drought in others. The frequency and intensity of storms and the resulting havoc will multiply as is already evident in the various parts of the globe.

The Paris summit conclusions signified that the international community has recognised and accepted the accumulated scientific evidence on climate change. In Paris it was agreed that each individual country will identify and communicate its pledges through which they will participate in the global effort to address the causes of the change in climate. These pledges have to be updated every five years. The pledges registered so far, even if adhered to, are however insufficient to limit warming to well below two degrees Celsius, and preferably to not more than one and a half degrees Celsius, in line with the expectation of communities spread along coastal areas and low-lying islands. Much more is required to walk the talk.

To achieve the Paris targets global emissions must be reduced by not less than half not later than 2030. We must attain a carbon neutral status by not later than the year 2050.
In order to reach these essential targets Christiana Figueres and Tom Rivett-Carnac draw on the various proposals which have been made to date. They emphasise that the change required is significant: a change of this magnitude, they emphasise, would require major transformations in all that we do. It would require radical changes as to how we live, work and travel, along with changes to what we consume as well as to how and what to produce.

The sudden advent of the Covid-19 crisis has given a minor hint of some of the changes.
Telework must be a permanent component of our method of operation and not a temporary exception. Education can and should contain a more permanent online component.

Non-essential travel should be curtailed on a permanent basis. Where necessary, travelling should use sustainable means. This does not only include electrification of our cars, after drastically reducing their numbers, but also a substantial reduction of aeroplanes from our skies permanently. Acting on climate change means that tourism as currently practised has no future. Air travel will become quite costly if its considerable environmental impacts are internalised.

On a long-term basis the current intensive development of our road infrastructure also serves no purpose. Fewer cars on our roads will also signify extensive land use planning impacts. Local communities can then reclaim back our roads. With fewer cars there will be less need of parking space and/or garages. Our towns and villages may then be planned for residents, not for cars.

We need to appreciate and make full use of local agricultural products. However, agriculture must internalise its substantial environmental costs. The cost of production of meat and dairy products, for example, would be substantial if their environmental impacts are internalised. Christiana and Tom, comment that in 2050 food is expensive because it requires valuable resources to produce. “Water. Soil. Sweat. Time.” Clearly the current Common Agricultural Policy of the European Union has no future once we seriously start implementing the conclusions of the Paris agreement.

The impacts of Covid-19 are child’s play when considering the long-term impacts of climate change. Faced with climate change we have one practical option: a radical change in how we live, work and play. The Covid-19 rehearsal is nature’s clear warning. We ignore it at our peril.

A Green Vision – 50 years on

50 years ago Rachel Carson published her seminal book “Silent Spring”.

In 1962 Carson, a zoologist, argued that the use of pesticides had unintended consequences as whilst pesticides targeted pests they ended up affecting birds and their offspring. The result being a decrease in the bird population brought  about by intoxication as a consequence of the poisoning of the food chain.

Rachel Carson was the first person to give a popular voice to ecological concerns. In so doing she laid the foundations of environmentalism. It can be safely stated that her Silent Spring was the trigger of popular ecological awareness in the United States and Europe and to the consequential setting up of environmental NGOs as well as Green Political Parties.

Today’s generation is indebted to Rachel Carson for a powerful environmental movement in the four corners of the earth. We owe to her the popular awareness and understanding of nature’s fragility.

But obviously awareness and understanding is not sufficient. It must be our motivation to act. Planet Earth, fifty years after Silent Spring was published, is in a much worse state then ever. It has a temperature, it is warming up. Sea levels are rising. The climate is changing to one of less frequent but more intense storms which leave a trail of havoc in their path.

Water resources are declining.

Waste is not sufficiently understood as an underutilised resource.

The sea has also been heavily polluted and its resources plundered.

Consider the following observation made by Callum Roberts oceanographer at York University.

“The seas are the ultimate sinks. Chemicals get washed out of the soil and into streams and rivers. They should settle on the sea bed and stay there. However, fishing has become so intense, with boats dredging up scallops and bottom-welling  fish all the time, that we are constantly ploughing up these toxins, including DDT, and stirring them back into the water.”

The environment movement was born 50 years ago to make a difference. It was born out of a love for nature but is not restricted or limited to nature.  It has set out to implement  a green revolution : bettering our quality of life and as a result bequeathing a planet earth in a better state of health to future generations.
