Exclusive: Nearly half existing facilities will need to close prematurely to limit heating to 1.5C, scientists say

As Earth’s climate warms, incidences of extreme heat and humidity are rising, with significant consequences for human health. Climate scientists are tracking a key measure of heat stress that can warn us of harmful conditions.

Oil and gas majors are planning scores of vast projects that threaten to shatter the 1.5C climate goal. If governments do not act, these firms will continue to cash in as the world burns

There's no time for complacency, according to Dr. Peter Carter, founder of the Climate Emergency Institute

February 28, 2022. Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.

The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.

BERLIN, Feb 28 – Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.

Emerging ice-sheet modeling suggests once initiated, retreat of the Antarctic Ice Sheet (AIS) can continue for centuries. Unfortunately, the short observational record cannot resolve the tipping points, rate of change, and timescale of responses. Iceberg-rafted debris data from Iceberg Alley identify eight retreat phases after the Last Glacial Maximum that each destabilized the AIS within a decade, contributing to global sea-level rise for centuries to a millennium, which subsequently re-stabilized equally rapidly.

This was filmed at a UN press conference during the final days of COP26.

In Paris, all governments solemnly promised to come to COP26 with more ambitious 2030 commitments to close the massive 2030 emissions gap that was already evident in 2015. Three years later the IPCC Special Report on 1.5°C reinforced the scientific imperative, and earlier this year it called a climate “code red.” Now, at the midpoint of Glasgow, it is clear there is a massive credibility, action and commitment gap that casts a long and dark shadow of doubt over the net zero goals put forward by more than 140 countries, covering 90% of global emissions.

Temperature rises will top 2.4C by the end of this century, based on the short-term goals countries have set out, according to research published in Glasgow on Tuesday. That would far exceed the 2C upper limit the Paris accord said the world needed to stay “well below”, and the much safer 1.5C limit aimed for at the Cop26 talks.

A survey of the world’s top climate researchers shows a stark finding: Most expect catastrophic levels of heating and damage soon—very soon.

As a leading climate scientist, Paola Arias doesn’t need to look far to see the world changing. Shifting rain patterns threaten water supplies in her home city of Medellín, Colombia, while rising sea levels endanger the country’s coastline. She isn’t confident that international leaders will slow global warming or that her own government can handle the expected fallout, such as mass migrations and civil unrest over rising inequality. With such an uncertain future, she thought hard several years ago about whether to have children.

The United Nations secretary general, António Guterres, on Monday issued a blistering critique of the world’s failure to rein in global warming, calling on countries to return every year to review their climate targets — not every five years, as the Paris climate agreement spells out. “Even if the recent pledges were clear and credible — and there are serious questions about some of them — we are still careening towards climate catastrophe,” he said at the opening ceremony of COP26, the U.N. climate summit in Glasgow.

Scientists have warned that hydrogen could be a significant “indirect” contributor to the greenhouse effect when it leaks through infrastructure and interacts with methane in the atmosphere.

The enormous, unprecedented pain and turmoil caused by the climate crisis is often discussed alongside what can seem like surprisingly small temperature increases – 1.5C or 2C hotter than it was in the era just before the car replaced the horse and cart.

ome problems are so big, you can't really see them. Climate change is the perfect example. The basics are simple: the climate is heating up due to fossil fuel use. But the nitty gritty is so vast and complicated that our understanding of it is always evolving. Evolving so rapidly, in fact, that it's basically impossible for humans to keep up.

Vingt-trois agences fédérales ont planché sur la question durant plusieurs mois. Le quotidien passe en revue leurs conclusions les plus frappantes suivant les ministères concernés : Two dozen federal agencies flagged the biggest dangers posed by a warming planet. The list spreads across American society....

This article argues that resource and logistical constraints weighing on low-carbon energy and CO2 capture technologies are likely to pave the way for geo-engineering solutions such as Stratospheric Aerosol Injection (SAI), which demand negligible land, material, and energy inputs. This “climate transition without carbon transition”, though technically feasible, is far from being that simple, raising a whole new set of environmental risks as well as geopolitical, institutional, and ethical issues.

A UN analysis today revealed a bleak upward trajectory for global carbon dioxide emissions, despite new CO2-curbing plans by scores of countries, including major emitters such as the US and the European Union’s 27 member states.
