The #IPCC report shows:

At the moment, the world emits around 40 gigatonnes a year of CO₂ (and growing).

If the world reaches zero emissions by 2050, in each year until then, emissions must be no higher than 40% of 2021’s emissions on average. ⬇️ 🧵 To get emissions to peak and then start on a downward trend is fairly simple in theory.

There are several major changes that can be made in sectors like electricity, construction and transport, where there are readily available alternatives. ⬇️

The #IPCC report’s conclusion:

Staying below 2°C this century will only happen if emissions reach net zero by 2050 is well publicised.

But global emissions must peak some time in the middle of this decade. In other words, within the next few years.
⬇️ 🧵 This shows global emissions must peak by the middle of the decade for warming of just 1.5°C to be possible.

1.5˚C = considered the “safe” limit.

2˚C = based on accepting the impacts we think that we can cope with.

Neither limit means completely avoiding the impacts. ⬇️

The #IPCC report confirms:

As a result of human activities, the planet is changing at a rate unprecedented for at least thousands of years.

Climate scientist and lead author explains the profound changes of Earth’s oceans, ice and sea level rise ⬇️ Over the last decade, global average sea level has risen at a rate of about 4 millimetres per year.

This increase is due to two main factors:

- The melting of ice in mountain glaciers and at the poles

- The expansion of water in the ocean as it takes up heat⬇️

As global temperatures rise, the intensity of storms increases

The graph show how much wetter storms that historically occurred once every 10 years are likely to become at temperatures 1.5°C or more above the late 19th century average

A lead author of #IPCC report explains🧵⬇️ A number of factors are intensifying the water cycle, but one of the most important is that warming temperatures raise the upper limit on the amount of moisture in the air.

That increases the potential for more rain. ⬇️

The #IPCC report:

Under all scenarios examined, Earth is likely to reach the crucial 1.5℃ warming limit in the early 2030s.

Our climate scientists and IPCC authors explain why there’s still reason to act if Earth exceeds that limit. ⬇️ 🧵 Under the 2015 Paris Agreement, nations agreed to hold global warming to well below 2℃, and preferably limit it to 1.5℃.

The first global stocktake of that agreement will be held in 2023.

That’s one of the reasons global warming levels are being so keenly watched right now.⬇️

The #IPCC report has been released. Here are what the experts say:

For the first time, the IPCC states unequivocally — leaving absolutely no room for doubt – humans are responsible for the observed warming of the atmosphere, lands and oceans. 🧵⬇️ Earth has warmed 1.09℃ since pre-industrial times

The #IPCC recognises the role of natural changes to the Earth’s climate

But it finds 1.07℃ of the 1.09℃ warming is due to greenhouse gases associated with human activities = pretty much all global warming is due to humans ⬇️

For many years, people believed antibiotic resistance was primarily driven by imprudent use of antibiotics.

But growing evidence suggests that environmental factors may be of equal or greater importance to the spread of antibiotic resistance.

Most faecal matter contain resistant genes and bacteria which go directly into surface and groundwater.

EXCLU: Boris Johnson supporters want no-deal #Brexit, less talk of climate change – new survey of party members reveals.

theconversation.com/0-118633

Thread based on analysis by @ProfTimBale and Prof Paul Webb ⬇️ While only around a quarter of the wider British public support leaving the EU without a #Brexit deal, 85% of Johnson’s supporters within the party are keen on a no-deal departure.

66% of Conservative members said the UK should leave without a deal.
