Major contributor in the fight against plastic pollution around the island Joe Issa, urges on more students around the world into peaceful protest against the slow and inadequate response to global warming, citing the Inter-governmental Panel on Climate Change (IPCC) report and the Earth System Dynamics study, which confirm what many scientists have been warning for years: 2 degrees is not a “safe” threshold. Negative impacts are already underway and will only get worse.
Issa explains that “whereas the leaders of the world have agreed to cap temperature rise to 1.5 – 2 degrees centigrade above pre-industrial levels, the studies show there is a huge difference between the impact of a 1.5 degree rise and a 2 degree rise.”
Issa, who supported the ‘1.5 to stay alive’ campaign during the last two international conferences on global warming, says he fears that “what seems to be an insignificant half a degree warmer is very deceptive as it can double the fresh water loss at 1.5 degrees and cause sea level to rise five times higher,” noting that “a 2-degree cap is not a safe zone.”
Issa sides new knowledge which says to delay carbonation is to consign millions of people in tropical regions to less food and in the Mediterranean to less water — with all the attendant health problems and conflict. “We’re allowing more heat waves and higher seas. We’re giving up on the world’s coral reefs, and with them the hundreds of species that rely on them.”
Issa agrees with the study, which argues that “the longer we wait, the more human suffering and irreversible damage to ecosystems we inscribe into our collective future. But there’s no hiding, no escaping the imperative to decarbonize. It must be done if our species is to have a long-term home on Earth.”
But capping warming at 1.5 degrees will require major, sustained global action and there isn’t much time to take the necessary decisions, the studies say. “The window for hitting 1.5 degrees is rapidly closing…at the present rate of emissions, the carbon budget for a good (66 per cent) chance of limiting warming to 1.5 degrees will be used up in four years.”
According to the studies, to hit the brakes at 1.5 degrees, global carbon emissions would need to immediately begin plunging, faster than they ever have, and hit zero by 2050 (and then go negative), the Associated Press wrote.
