In perhaps the most furious climate speech by an established politician directed at a sitting president, Joe Biden yesterday accused Donald Trump of being a "climate assassin".

During Trump's time in power, the United States has fallen to last place, after Saudi Arabia, due to its climate policy.

Or rather a lack of climate policy (according to the Climate Performance Index).

The survey is based on the 61 countries that together account for 90 percent of global carbon dioxide emissions.

Donald Trump has not ignored the climate issue.

Instead, he has systematically torn up the environmental and climate laws targeting the three largest sources of emissions in the United States (laws passed by President Barack Obama), ie the requirements for reduced CO emissions for cars, stricter emission requirements for the coal power industry and the latest ban on emissions of methane gas in gas and oil extraction.

Climate crises of emissions long before Trump

According to Donald Trump, these are reasonable measures at a time when the US's focus is on saving the economy and creating new jobs.

All environmental regulations are an obstacle to business, according to Trump.

When he visited burnt areas in California yesterday, he dismissed the climate crisis with the words "scientists know nothing".

Although the government's own climate experts have warned that continued burning of fossil fuels will triple the risk of forest fires in the western United States.

But to indirectly accuse Donald Trump of the ongoing forest fires and floods that is to be expected in the next few years is unreasonable.

The climate change we are now witnessing is the result of emissions that occurred long before Donald Trump became president.

In light of this, it is not difficult for the challenger Joe Biden to put together a climate policy program that appears to be both bold and ambitious.

He has promised to invest two billion dollars in renewable energy and major infrastructure projects such as building the world's fastest and most efficient railway network.

Investments that will create millions of new jobs, Biden promises.

He has promised to gather for a global climate summit within 100 days and try to speed up the lame negotiations that have suffered severely from the withdrawal of the world's most powerful country.

Climate commitment is greatest among young people

The climate is receiving increasing attention among voters.

Climate commitment is greatest among young, radical Democrats.

Joe Biden is criticized for failing to enthuse those who would rather have seen Bernie Sanders as the Democrats' candidate.

Should they stay home on election day, it is a victory for Donald Trump.

That is why Joe Biden has chosen the climate as one of his four main issues in the election campaign.

More than half of all Americans now state that they notice climate change in their immediate environment.

In ten years, it has gone from 44 percent to 60 percent who believe that the climate crisis is a major threat to the country's security.

But it is an issue that cuts through the party lines, the concern is twice as great among Democrats than Republicans.

On the other hand, there is a not insignificant proportion of center-right voters among Republicans who also say they are worried about climate change.

If they now see that the climate crisis threatens the lives of houses, homes, companies and people, it could be one of the decisive questions on American election day.

United States after China's largest emitting country

The opinion polls on the climatore were also done before the forest fires colored the sky blood red over San Francisco and the media reported on a 13-year-old boy who was found dead in a car with his dead dog on his lap, where they sought protection against the fires.

It is too early to say what will be decisive on election day.

The United States is also currently experiencing a historic pandemic, high unemployment and a devastating conflict over police violence against black Americans.

But how the American people will vote on November 3 is also a matter of fate for the global climate.

After China, the United States is the world's largest emitter of greenhouse gases.

During Donald Trump's time in power, he has partly decided to leave the Paris Agreement but also withdraw the promised two billion dollars to the UN's green climate funds that will help vulnerable countries to protect themselves against extreme weather and other climate consequences.
