UN climate catastrophe can be stopped now or never

(ORDO NEWS) — The time has come “now or never” to limit the catastrophic increase in temperature and climate disruption, the UN experts said in the latest warning to governments. An analysis of their report is published on Live Science.

“Fast, deep and immediate” reductions in global carbon dioxide emissions, which should start falling by 2025 and halve by 2030, must be implemented immediately across all sectors of society if we want to keep temperature changes at or below a dangerous threshold 1.5 degrees Celsius,” says a new report from the Intergovernmental Panel on Climate Change (IPCC).

However, reducing global emissions alone will not be enough. Keeping warming within tolerable limits will require further development of nascent technologies to suck carbon dioxide directly from the atmosphere and store it underground. Such technology will have to be accompanied by the planting of new forests, as well as the development of hydrogen fuel and the redesign of transport systems in cities.

We are heading towards a climate catastrophe: major cities under water, unprecedented heat waves, terrifying storms, widespread water shortages and the extinction of millions of plant and animal species.

Humanity already has the technology needed to cut global greenhouse gas emissions by at least 50% by 2030, according to the IPCC, and many measures are low cost and could even save money. These include increasing investment in renewable energy, further carbon sequestration in the soil, reducing methane emissions, and so on.

The report also notes that the cost of solar, wind and lithium battery technologies have plummeted since 2010, leaving the economic benefits of limiting warming to 2 degrees Celsius (or below) far outweighing the costs associated with switching to these energy sources.
