Changing attitude to nature

  • No comments
For most people, "changing attitudes to nature" is nothing more than a purely academic side job, but this change is deeper. A fundamental and necessary change is required to preserve and protect biological diversity and to protect human and animal populations around the world from harm

How can you work in this heat?

New findings reveal that heat stress affects the bodies of those of us who work mostly outdoors, and may also impair work efficiency. In the coming years, given the climate crisis, the phenomenon is only expected to get worse. Will the heat in the future force us to work harder?

Heat waves are common in India in spring and early summer, especially in May, which is usually the hottest month. But they are usually tempered by the beginning of the monsoon season from late May to September; This time they went ahead and extended; 12 of the last 15 years have been the hottest in the Indian subcontinent

Hot, Hotter, Frozen: The Surprising Reason for the "Little Ice Age"

In a new study it was discovered that the reason for the occurrence of the "Little Ice Age" was actually overheating in the period that preceded it. Could the extreme cold return a second time nowadays due to the increase in global temperature and how is this related to the weakening of the Gulf Stream?

Towards the next storm - less rainy winters, but the storms will be more powerful and concentrated

After we experienced the Carmel storm this week, a new study shows that future storms will be drier and more concentrated, that is, focused over smaller areas in space. They will last for short periods of time but will be more powerful

Autumn is disappearing and turning into a continuation of summer. Studies have shown that in Israel and its surroundings the warming was much greater than the world average. A study by the Institute for National Security Studies showed a connection between climate change in the region and civil wars in the region. The climate crisis has long been no longer a theoretical issue

Research: The international pressure on Israel to reduce greenhouse gas emissions - affects the local policy discourse

Avery Eitan from the Hebrew University, the leader of the study, explains: "The international agreements signed by Israel, as well as the pressure exerted on it by various countries to reduce greenhouse gas emissions by increasing the use of renewable energies, are indeed bearing fruit and actually influencing the Israeli policy discourse on the subject, which tends to neglect issues concerning to adapt to climate change"
