They should be prepared to be proactive in explaining the nature of scientific evidence to those who ultimately make the policy decisions. Ongoing climate change driven by greenhouse gas emissions is often discussed in terms of global average warming. For example, the landmark Paris Agreement seeks to limit global warming to 1.5 degrees … They looked at how the removal of rapid Arctic warming would affect temperature projections in a plausible intermediate emissions scenario and calculated the average temperature projection across all models. The Arctic is currently warming nearly four times faster than the global average rate. The new study, published in the journal Earth System Dynamics, aimed to estimate the impact of this faster warming on how quickly the global temperature thresholds of 1.5C and 2C, set down in the Paris Agreement, are likely to be breached.
‘Our Fragile Moment’ finds modern lessons in Earth’s history of climate
Published research is rarely black or white and there are significant areas of uncertainty and debate among experts in areas such as, for example, climate change, insecticides and bee health, and badgers and bovine TB. The policy-makers err towards a consensus view rather than a sound understanding of the underlying science. Yet there is often a disconnect between our policy-makers and the scientific community.

Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. The first of these referred to the rate of heat loss from the earth and the length of time it would have taken to form its solid crust. The second referred to such topics as the detailed shape of the earth and the dynamics of the earth-moon system. The third referred to the heat of the sun, particularly the rate at which such heat is being lost, compared with the total amount of energy initially available. Water trapped in meteorites from the asteroid Vesta closely matches the composition of Earth’s oceans. Comets such as 67P/Churyumov–Gerasimenko have, in general, too much deuterium to be Earth’s primary water source. Alexander’s research, along with that of many others, builds a strong case for a chemical match between Earth’s water and chondrites’ water.

“What’s clear is we are a force of nature. Human activity – the burning of fossil fuels and land change – is having a massive influence. We are in the midst of this giant geoengineering experiment.” “When I wrote this story I did not see it as a blockbuster,” Gwynne recalled. “It was just an intriguing piece about what a certain group in a certain niche of climatology was thinking.”
Time travel is the concept of moving between different points in time, just like you move between different places. In movies, you might have seen characters using special machines, magical devices or even hopping into a futuristic car to travel backward or forward in time.
